Hitbox Dissonance



"thats the result of all the training of Ryu, to make a invisible punch"

"There are no hitboxes, there are just ideas."

- Medibot, Let's Play Sonic Shuffle

In video games, a hitbox is the part of an object considered 'solid' for the game's purposes. It would be very mathematically complicated to model all the characters' body parts and check when they've touched, so instead, a rectangular or cubic region of each character is chosen as the hitbox. When two hitboxes overlap, the game knows that the characters have collided; when an attack lands inside a character's hitbox, it has hit the character. Fighting Game jargon usually differentiates the two boxes by calling the attack's a hitbox and the target's a hurtbox; in other genres the term "hitbox" usually gets used for both.

In the early days, it was literally a box, as a rectangular or circular solid is less math-intensive when doing the collision checks. More modern 3D games have a whole separate model made of hitboxes that closely follows the rendered model in logical space, many including different values for different body parts to enable hits to weak points For Massive Damage.

Sometimes, whether intentional or not, hitboxes don't match up quite right with the graphics, thus producing Hitbox Dissonance. This can take several different forms:


 * An enemy's hitbox is too small. This makes the enemy harder to hit, and tends to happen with small enemies that are already Goddamned Bats to begin with.
 * An enemy's hitbox is too large. This is especially problematic for enemies that attack via Collision Damage, and in extreme cases can break Willing Suspension of Disbelief when shooting the air two feet away from the big guy makes him bleed anyway.
 * The player's hitbox is too small. Although it makes the game easier against enemies (especially when dodging bullets), it can be more difficult trying to land on a platform when you don't know how much platform you have to work with.
 * The player's hitbox is too large, or extends beyond the visible portion of the sprite. This can be a rather glaring form of Fake Difficulty if your character is a One-Hit-Point Wonder.
 * Projectiles' hitboxes are too small. On magic, fire, or energy projectiles, this can be Handwaved as only the core of the projectile counting, with the aura around it just being gases or debris of some sort.
 * Projectiles' hitboxes are too large. This can prevent the player from shooting through small spaces or around cover, which may or may not be a good thing, depending on the game.
 * The hitbox is disjointed: the hitbox and main damaging areas do not follow the physical logic of the attack.

Fighting Game fans tend to explode when they encounter this type of problem. Maybe even the winner will Rage Quit, having unearthed the inherent unfairness. Regardless, it occasionally can be considered a Good Bad Bug.

Action Adventure

 * MediEvil (1998 video game) included sentient, man-eating pumpkins with a headbutting attack that did damage before the animation started.
 * One of the many, many flaws of advergame Darkened Skye. The hitboxes on the enemies are rather smaller than the models (especially, yes, the Goddamn Bats), while your own hitbox is larger...but your weapon's hitbox seems to be smaller. Fights are frustrating, to say the least.

Action Game

 * The original 8-bit Ninja Gaiden trilogy nearly falls into the realm of Fake Difficulty because of its poorly sized and placed hitbox areas, both in the player character as well as in the enemies. The Act I boss of the original suffers from this too. You can have your sword be centimeters from hitting him, and you'll still do damage.
 * In Toy Story for consoles, the hitbox for Buzz during the gas station fight is noticeably large when he's bounding around the stage, so you get hit unless you're directly below the arc, making this fight unfairly hard.
 * In Bugs Bunny Crazy Castle 2, both Bugs Bunny and his enemies had tiny hitboxes, which could lead to odd situations where Bugs Bunny could literally walk right through them without any harm. The weapons Bugs could pick up, on the other hand, had large hitboxes, and in most situations, had no trouble hitting an enemy's small hitbox. It almost completely works in the player's favor, at least, and since Bugs is a one hit point wonder, you may need all the help you can get.
 * In Battle City and Tank Force, players and enemies actually "snap" from one half-tile to another even though sprites seem to go smoothly. This was done to ease navigation as the problem was apparent in Tank Battalion.
 * The hitboxes for Chief Scalpem/Wigwam's knives in Sunset Riders don't always seem to be in the same place as the physical knives, meaning that in some cases, the safest place to be is directly in their path.
 * Alien Syndrome for the NES had a severe case of the "bigger" kind, in some cases, you could shoot the air and still kill your foes, likewise you could die from touching the air near them.
 * Presumably this occurred with things like walls in Superman64, since a few cases shown in The Angry Video Game Nerd's review had the player get stuck despite being about three feet from the actual wall. See here

Driving Game

 * Racing series Burnout and Excite Truck\Bots also use this, with "near miss" and "tree run" bonuses. The "small hitbox" is your whole car in these games though, and the "large hitbox" is the area around it.
 * Many early driving games has entirely rectangular Hit Boxes, which was really egregious when it extend all the way to the side-view mirrors.

Fighting Game

 * Soul Calibur
 * Soul Calibur's custom characters suffer from this. Since all custom characters are the same height but use a standard character's weapons, the standard character's hitbox is mapped onto the custom character, which leads to problems when using the style of a particularly tall or short character.
 * Tekken 5 was pretty notorious for grounded mids, especially in wall combos. To clarify for non-Tekken players: some mids do have the property of hitting a character on the ground (downward chops, rising kicks, etc). But there were a lot of straight thrusting attacks that hit a person almost completely lying on the ground or rolling to the side. One big offender was Anna's Tread Water kicks to Judgement Kick (f,f+3,4,3~b, 3), the last of which was a front kick which would hit a grounded opponent or sometimes even an opponent behind Anna.
 * MUGEN - Disjointed hitboxes are also one of potentially many signs of a badly made character. An Egregious example is Metal Greymon, whose hitboxes bear absolutely no resemblance to the sprites (which are a random assortment of Digimon characters, none of them animated).
 * Super Smash Bros. has a lot of these problems, partially due to the fact that a single attack will have several different hitboxes with sometimes wildly different strengths.
 * Ganon's down special continues for about four seconds, but by the third second it stops doing potential damage. This creates the odd situation where you should be going through someone with your foot but they smack you back. More evident in his recovery (up special) where not only is it unlikely that you will latch onto an opponent, but the punch at the end will most likely never hit.
 * Snake's side and up tilts are absolutely ludicrous in this regard. Both of them have hitboxes which strike at least a foot in front of where his feet/hands end. This is especially noticeable with his up tilt, which makes Snake kick straight upwards into the air and yet can hit an opponent seemingly three feet in front of him.
 * In Melee, Marth and Roy's grab hitboxes are twice as long as they really should have been. Their standing grabs actually outranged Yoshi, despite them having seemingly standard grabs and Yoshi having an obviously ranged grab.
 * Quite a few characters can hit people standing behind them thanks to attacks with hitboxes that extend behind their back or over their shoulder.
 * Hattori Hanzo's Limit Break in Samurai Shodown III had a hitbox that stuck around nearly a second after the actual explosion. Worse, it did not combo with the rest of the attack, meaning that a person who blocked the attack could let off the block a moment too early, and end up taking the full brunt of it anyway.
 * In Blaz Blue, the hitbox for Ragna's Carnage Scissors is much taller than the graphics would suggest.
 * It is even more noticeable with Hakumen's Yukikaze. The thing hits the entire horizontal plane and even double jumping will not save you unless you have moves that rocket you further up screen.
 * NES version of Yie Ar Kung-Fu suffered for this quite a bit where a hit was registered a miss and vice versa. The fact that the enemy was mostly made out of background instead of sprite contributed to that.
 * Killer Instinct was known for allowing some truly absurd crossups - essentially, kicking your opponent in the face by jumping over their head and grazing the air a metre behind them with your left knee.
 * As you'll find below, Touhou is famous for how important your character's hitbox is. This even carries over to the fighting game spinoffs, where sometimes dodging that instant-kill spellcard or that one bullet that would knock you out upon hitting relies solely on your knowledge of hitboxes.
 * Street Fighter III has a problem with so called "nails" where attacks would extend just a little to far that they should, as seen above in the quote.
 * Super Street Fighter IV: In a shocking nerf to fan favorite Makoto, who in Street Fighter 3 was able to pull combos like this, her EX Grab didn't extend past half her arm's length; they've since fixed this in Arcade Edition.

First Person Shooter

 * There's nothing quite like putting bullet holes into empty air in MAG.
 * In Doom, for collision with objects, monsters, and projectiles, everything is essentially treated as having infinite height.
 * The sprite for Revenants is noticeably taller than their hitbox. The difference between sprite and hitbox doesn't manifest as aiming difficulties, but it allows Revenants to walk in tunnels that they shouldn't fit into.
 * The Spider Mastermind seems to take up space at least four feet further on each side than it appears. This often leads to it getting hung up on walls and other monsters when used in custom levels.
 * The plasma rifle's shots are often blocked when just what one would think is just "glow" from them graze a wall.
 * There's also a bug where a bullet can completely fail to hit its target depending on where the shooter and the victim are standing in open space, even at point-blank range. Click here for details.
 * Hitbox Dissonance also factors (deliberately) into the final boss of the Doom 2, "The Icon of Sin", whose hitbox is located at the end of a tunnel on the boss monster's forehead, which is nearly impossible to hit directly, and can only be reliably damaged with splash damage from rockets.
 * Unreal brings us both monster variants:
 * The Titan, being essentially a twenty-foot reptilian gorilla, isn't very compatible with the simple collision cylinders used in the game, thus ending up with at least a minor form of the "shoot the air next to him" trouble. That said, this is probably a good thing for game balance due to his immense power and durability.
 * The pupae and predator enemies are best taken out from afar, since once in melee range, their narrow collision cylinders make them nigh-untouchable.
 * The Spy of Team Fortress 2: Landing a successful backstab (which is instant death) depends on the view angle of the victim, and not the actual pose of the character, causing dissonance when combined with some animations. This is in addition to lag and the game's rather odd way of calculating melee hits (using the player's bounding box) and, well, you end up with a lot of sidestabs and facestabs. Numerous tweaks and updates have gone toward trying to get it right, though you can't please everyone.
 * To the Spy's considerable advantage: a disguise does not change your hitbox. A headshot to your fake head will hit you in the torso if the model is short enough.
 * To add to this: the Spy can disguise as his own team, so the enemy sniper may not even know the player is a Spy.
 * Better still, the Sniper is taller than the Spy. It's very possible that what would have been a headshot on a real Sniper will go straight over your head.
 * With the Sniper's bow unlock, the Huntsman, it's quite possible to aim a few inches to the left or right of an enemy's head and still get a perfect headshot, as it uses the projectile hitbox (which is the same for every class) rather than the bullet one (which varies by class). The arrow, rather than sticking the body as it normally would, simply disappears.
 * Being hit by an enemy with a melee weapon in general is wonky - It will often appear the enemy is several feet from you and hitting you with a really long fist. This is because, rather than using hitboxes, melee attacks use one big map-aligned cube to determine hits.
 * Further compounding the issue is several melee animations, namely all of the Pyro's weapons and the Demoman's two-handed weapons, are disjointed relative to time. What this means is from your perspective, the attack hits while the Pyro/Demoman is still winding up for the strike. The Pyro/Demoman don't see this, however; their first-person animations are synced properly.
 * Taunt kills are even more silly. It's possible to temporarily dislocate the hitbox from the onscreen model, making it so that, for example, Sniper's arrow stab shanks someone directly behind him. Even without that, the range for several of them extend far enough to where the attack's animation doesn't have to actually touch the victim to do the damage. Most taunt kills even hit above you, so if your enemy is standing on your head they still get shafted. This isn't even touching on Heavy's ability to shoot his Finger Gun a full 90 degrees above/below where his arm is pointing.
 * Speaking of taunts, animations like taunts and post-round humiliation stances (and others like spy crabs) do not have matching hitboxes, meaning you need to shoot where their head would be if they weren't taunting, spycrabbing or being humiliated (thankfully, taunting opponents are immobile and humiliation gives you unlimited critical hits, mitigating the issue).
 * In Counter-Strike: Source, players' hitboxes actually lag a step behind their models. This can lead to some frustrating missed shots or WTF deaths. This happens in just about any online shooter to some extent, varying depending on lag and netcode.
 * For the technically-inclined, an excellent article on how Source engine games (Half-Life, Counter-Strike etc.) usually handle this can be found here. Making sure that gameplay seems fair (even at the cost of it actually being fair) is an important priority for developers who want the game to be any fun.
 * When zoomed, the Sniper's hits are calculated by precision, limb-for-limb hitboxes. When not zoomed, he gets the same single box as any other class. Since the sniper rifle is perfectly accurate, this actually means that you are more likely to hit someone with a non-scoped shot. Of course, without the scope it only does 50 damage maximum with sharp falloff.
 * Call of Duty: Modern Warfare 2 frequently has seemingly wonky hitbox detection, as seen from killcams in online play. The hitboxes are actually very, very detailed, but even a small amount of lag (as in, normal amounts of lag), can turn a kill into a miss. Headshots are, therefore, best pushed into the realm of luck rather than skill with anything other than a sniper rifle.
 * "Normal" hitboxes that players are used to demonstrate this trope. The premise is simple: players feel cheated when their bullets go through enemies, but badass when they're the ones dodging bullets. So, heroes tend to have smaller hitboxes than their sprites would suggest - this is why Mega Man puts his foot through the floor whenever he lands from a jump.
 * Killing Floor had effectively broken hitboxes on a pair of high level monsters, one had his head hitbox buried in his neck in such a way that it was more or less impossible to hit without attacking from above, another had his head hitbox floating in mid air above his left shoulder. This meant that new players attempting to gain head shots by shooting at the head found it impossible. Veterans that had learned about this and knew where to aim or how to exploit AI could hit them, but of course when this bug was finally fixed there were cries that the devs were pandering to the scrubs and had ruined the difficulty.
 * In Left 4 Dead the Hunter's hitbox is actually a ways ahead of him, as various Youtube tutorials have pointed out. One must take this into account when trying to melee them during their pounces. This has also extended to the Jockey and the Spitter in the sequel. The Jockey can leap and latch onto a survivor from at least 2 feet away due to its ranged hitboxes and the Spitter's acid patch has a slightly larger hitbox, leading to players being damaged from the acid even though their character models aren't physically standing in the acid.
 * The sequel also has wonky hit detection with melee weapons. Sometimes you can clearly hear the weapon smashing into a zombie's torso, indicating you hit them, but they may sometimes not take any damage at all and will continue to attack you. This problem is more noticeable with short ranged melee weapons like the machete and nightstick due to them having fewer hit boxes for being short weapons. One would expect this to happen in an online game where lag can pop up and mess with the timing of your swings, but this can also happen in single player mode, which is offline.
 * The survivors generally have the same sized hit boxes so that no survivor has an advantage over another survivor, but Zoey's hit boxes are slightly smaller than everyone else.
 * In Metroid Prime 2, Emperor Ing's second form takes an absurd amount of damage from the Screw Attack if you land near his feet. Not a direct hit, you must land near him. He'll crumple in under a minute. Also, his chin seems to block many blasts if you shoot him from ground level; try jumping. Note that the Wii rerelease fixed this.
 * When diving to the ground in Battlefield 2, the animation shows a running character jump forward before landing on the ground. The hitbox, on the other hand, changes to 'prone' instantly, making the diving character very hard to hit, even if you know you shouldn't aim for the airborne body but for the ground below him.
 * The hitbox wasn't the only thing that went straight to prone. So did the diving players accuracy. This is why before it was fixed in a patch Dolphin Diving was the biggest Game Breaker the series had ever seen.
 * Postal 2 has an egregious example with Gary Coleman, especially noticeable when he gets into a fight with NPCs that ALWAYS aim for the head and make puffs of blood appear ABOVE Gary's head. This is presumably done to maintain balance in multiplayer and avoid the issues that GoldenEye had with everyone trying to pick Oddjob.

Maze Game

 * Pac-Man has a smaller hitbox than it seems. Especially apparent in Championship Edition series. This is an odd case in which his hitbox is based on his position in the maze rather than his actual sprite. It's because of this that you will very rarely see Pac Man pass right through a ghost without dying at times.

Miscellaneous Games

 * Many games in Action 52 suffer from this.
 * The Robot Ninja Haggleman games from Retro Game Challenge gives enemies a slightly larger hitbox than the size of the enemy. This means that if you approach from the wrong angle, you will get hit without actually touching the enemy. This is particularly bad for Dark Hagglemen, who have an animation where they laugh after deflecting your attack - but which doesn't turn off their hitboxes.
 * In NES Remix game play pauses as soon as you die die, making any instance of this extremely noticeable.

MMOs

 * World of Warcraft has some examples of both. Many bosses have very large hitboxes to make it easier for melee classes to attack them. Kologarn for example has a hitbox that is so large that you can stand near his right arm and use an area-of-effect attack to hit both of his arms and his body (his body and arms have separate hitboxes). Some bosses on the other hand have very small hitboxes. Saphiron for example has a hitbox that's about the size of his body, with his head and tail extending outside of the hitbox, meaning melee classes pretty much have to stand right under him.
 * Sapphiron is a stonking great dragon, so if his hitbox really covered the same amount of ground he did, it would fill the whole room.
 * Thaddius: one of his boss abilities is to charge players up with either positive or negative charges. If the two groups stand too close together, you all die, so his hitbox is unnaturally big, or nobody would ever be able to kill him.
 * Lots of wipes were caused by some douchebag throwing Baby Spice on him.
 * Kel'thuzad can ice block a player, which will chain and ice block anyone else within 10 yards of that player, who will then chain to anyone within range of them. Generally if this happens to more than a couple players at once, it's a wipe. His hitbox is much larger than he is—just big enough that three melee classes (usually offtanks in case the main tank gets blocked) can stand at the points of a triangle around him and still stay 10 yards apart. On the flip side it means that any other melee classes in the group need to stand back and watch, while also not getting to close to anyone else....
 * A common method of dealing with this, when in a group that has lots of melee types, is to exploit the lack of collision detection by positioning people directly on top of each other. If one of the melee clumps freezes, then yeah they're all hurt, but it's manageable and won't chain to anyone else.
 * The proto-drakes in Wrath of the Lich King are pretty notorious for lousy hitboxes. Since they fly you don't often have a ground reference and the ground-hitbox-indicator-circle-thing (new trope?) is often hard to see and irritatingly small, which ends up with the player often getting "Not in range" or "You are standing behind him you dolt" messages when trying to melee.
 * Any player character, especially after factoring in server lag. You can get Ambushed or stunned from twenty feet away, shot (which you supposedly can't do at close range) between dual-wield melee swings that are supposed to go off simultaneously, be standing on top of an opponent inside their rendered model and see "too far away", etc.
 * At release, this was notoriously bad for feral druids in cat form, because the character in that form is a long, low-to-the-ground quadraped, the hitbox was still shaped like a humanoid (tall and narrow), so a kitty had to look like it was nearly inside a mob before it counted as being within hit range. This problem improved over time with patches.
 * Some attacks home into a certain body part for cosmetic effect, specifically shadow priest spells, being psionic in lore meaning they usually appear at and around the head hitbox. Sometimes on non-humanoid mobs the head hitbox is in some very odd places. Sometimes the hitbox wasn't placed correctly such as in Karazahn where mind flaying skeletal horses before the first boss made you HIT THE WALL about 20 feet away, needless to say, it was pretty comical to make fun of Spriests for damaging the deadly wall ghosts.
 * In a less violent sense, this applies while trying to interact with large sprites - collect items from a monster you killed, or talk to an NPC - when you might have to find a specific (unintuitive) spot to stand in order to be "close enough" to the core of the sprite. Sometimes you have to stand right inside the sprite, or inside its tail, or the like, in order to be close enough to interact with it at all.
 * Some more recent offenders include Lord Marrowgar, the first boss any player will see in Icecrown Citadel. For the uninformed, this guy is a big, floating mess of bones with arms and a really big axe. The standard manner of fighting him is to stand inside his hitbox to avoid a nasty line-of-fire-along-the-ground attack. However, hunters are required to stay at least 5 in-game yards away from him in order to use their ranged attacks (their only really powerful ones). This guy's hitbox is HUGE, and very difficult to actually pinpoint due to the fact that he's, you know, floating above the ground and doesn't directly touch the floor for reference. If a hunter gets caught on a bone spike, they'll likely be halfway across the room, away from notice if people aren't paying attention.
 * Tauren players have the largest hitbox of any race, this caused issue at the beginning of arenas, when Tauren melee had a hitbox large enough to allow their weapon swings to pass through the pillars in the nagrand arena, resulting in a game of maypole where the unlucky recipient couldn't even defend themselves, predictably, this was fixed pretty quickly.
 * The stone drake Slabhide is particularly problematic on Heroic difficulty due to this. During the fight he unleashes a crystal spray that people have to hide behind fallen stalactites to avoid. However, if people are inside his enormous hitbox the attack won't register the stalactite as blocking it and the attack will still damage them, even though by looking at the screen there was clearly a giant block of stone between the character and the drake.
 * The Ancient Smoldering Behemoth, one of five bosses from the daily quest chain in the Molten Front, is easily the largest of the monsters, but has an extremely small hitbox, so that you have to stand underneath him in order to melee him. The problem is that he also uses an area of effect attack centered on himself (which you must avoid for an achievement), making it more difficult to run out and back.
 * Monster Hunter
 * Players often shout abuse at the plesioth. Its hitboxes are grossly misaligned, which makes dodging its attacks extremely irritating. Its "hipcheck"—an attack where it slams you with its hip—is infamous for having a hitbox several meters bigger than the creature's body. Most people, even the most dedicated swordmasters, decide to make a bow solely to be able to snipe the Plesioth from beyond its wonky hitboxes' range.
 * A similar issue happens whenever a monster attacks by spinning in place to whip its tail around (which just about every wyvern or dragon with a tail does). Even if the monster is so tall that it looks like its tail would just whiff over your head, it'll knock you down.
 * Note that wyverns with similar body types don't necessarily have the hitboxes scaled to match. It's entirely possible to avoid a gypceros's tail sweep by standing directly under its crotch, but trying the same trick with a monoblos or diablos (who are both quite a bit taller than a gypceros) will get you clobbered.
 * This has been improved somewhat in Monster Hunter Tri, where you can avoid some tail swipes at distances that would have surely gotten you thwacked in earlier installments.
 * In terms of your own attacks, the hitboxes are slightly askew. When fighting against a large monster, it can be difficult to Attack Its Weak Point. If even a slight bit of your swing hits the hardest armor, your attack bounces off, the monster takes little damage, and you stand there like an idiot for a second while the monster has time to attack. This makes the Barroth a Wake Up Call Boss, since its the first monster to be mostly covered in hard plating.
 * It also works both ways though, as since most of your melee weapons involve swinging them around, if you're under a monster and your weapon just grazes their weakness, the game will register it as a full-fledged hit. There are some stories going around where people have cut off tails just by poking the tail with a weapon.
 * The Hitbox on a Mobile in Gunbound is literally only one pixel wide. This means that you can unleashe a Macross Missile Massacre or Bullet Hell on an enemy, completely obliterating the ground beneth them, only to have them still be alive, perched on that one pixel your blast did not destroy. This also makes it insanely hard to kill the opponent, as most projectiles don't explode unless they connect with another hitbox, and with the ground gone and the opponent being literally one pixel wide, it's considerably harder now to kill them.

Platform Game

 * Mega Man 3 has a lot of this, because Mega Man's hitbox is a rectangle. Mega Man's hitbox consistent for all the NES games (not including MM 9, which is an entirely different engine), but it's actually possible to see it, if briefly, every time the Blue Bomber gets hit. The white "damage field" that blink through Mega Man is exactly the same size of the hitbox. It's slightly taller than Mega Man, and slightly wider.
 * Where it gets ridiculous is when Mega Man fires his weapon while standing still. He leans forward, extends his arm, and projectiles emerge from the end, but his hitbox remains the same, and thus the entire outstretched arm has no collision detection at all! He can shove his arm into any obstacle and launch bullets from inside it if he pleases. In games where Sniper Joe's shield has its own hitbox rather than simply a shielded state for the whole sprite during certain animations, Mega Man can tiptoe up to Sniper Joe, reach past the shield, and shoot him directly, without having to wait for Joe to lower his shield.
 * The Apogee platformer Pharaoh's Tomb had rectangular hitboxes around everything, which could result in the player character being killed by something he apparently wasn't even touching when the corners of their hitboxes overlapped. There were also several places where, in order to jump over a wide gap, he had to walk right out onto the edge of a ledge until only the last pixel-column of his hitbox was still on the ledge—at which point he appeared to be standing several pixels out into thin air.
 * It gets stranger: You could actually jump to kick the monster into going the opposite direction and even walk on top of a monster's hitbox. It was up to you to stay on top; the monster wouldn't carry you along.
 * This is Handwaved in the manual: it is stated that you need some room to fire your weapon, so you can't kill enemies if you stand too close; this is actually because your hitbox will already touch the enemy at that point.
 * In I Wanna Be the Guy, The Kid's hitbox does not include the Cape Of The Hero or the Very Small Gun. That's extremely little difference, but it's required that you take advantage of it to be able to pass certain spike traps.
 * It also does not change during the vic viper segment, giving the whole thing quite a Bullet Hell feel.
 * In Ice Climber, the hitbox doesn't match the player while jumping which can often cause a player to go through floors while or not hitting enemies while being in the air.
 * Bugdom, a game that came free with the iMac, is another game with box-shaped hitboxes, which becomes rather obvious given the shapes of some enemies. This is most ridiculous when fighting non-flying bees, which both lack collision damage and essentially have invisible platforms hovering a few inches above their heads.
 * Sonic the Hedgehog
 * Tails' hitbox in Tails Skypatrol is only one pixel high, but the enemies have larger hitboxes than they should to make up for it.
 * One specific enemy from Sonic the Hedgehog 2, Shellcracker in Metropolis Zone, has an outright counter-intuitive hitbox. When his spiked claw-on-a-chain is extended, hitting him near the base of the chain hurts you. When his claw is retracted, hitting him on exactly the same spot hurts him.
 * NES game Treasure Master is all about this. First of all, your character's front hitboxes are very good and such, but however, if your back is at the enemy and enemy shoots you for an example, the projectile hits you from space where you could fill another protagonist's sprite. Enemies' hitboxes aren't bad, though.
 * Canabalt invokes this on purpose for the player's comfort. Buildings extend a bit past their visible right edges, and crates' hitboxes are a mere two pixels tall.

Real Time Strategy

 * Allegiance, being a team-based strategy/space combat hybrid, is especially susceptible to such problems, since flying every type of ship needs to be a fair experience for every player. Sometimes, the hitbox for a spacecraft with a complex shape oversimplifies the object's geometry a little too much. At the extreme, there is one ship that looks very small, with several thin wings, but acts as if all the wings were joined by solid surfaces, making what looks like a compact and difficult ship to hit an easy, bulky target in reality. There are also small, but annoying problems with the hit-boxes of a few space stations, which can be a problem since player ships often have to dock at these, and bumping into invisible walls when it looks like you should be flying into a docking bay is never fun. Fortunately, only a very few models suffer from these issues, and only require a little extra care. As the game is being developed by fans, there have been a number of attempts to create new hitbox models and fix these issues; some progress has been made, but the solutions aren't always easy to implement in practice... not to mention that in a few cases, some players have gotten used to the hitboxes, and don't want to see them fixed!
 * In Defense of the Ancients, the Keeper of the Light's Illuminate spell uses an effect similar to the Shockwave spell in Warcraft III. However, the area covered by the spell is a lot wider and somewhat longer than the visual effect, meaning that you can "dodge" the shockwave and still lose an assload of health.

Rhythm Game

 * Rhythm Games have a variation of this called the "timing window", which refers to how much a player can be off from the exact beat a note falls on when he/she hits that beat (graphically, how much of the note needs to overlap with the "hit zone", assuming a constant speed) for the note to be counted as a "hit". Some games, especially those created by Harmonix (Amplitude, Guitar Hero, Rock Band) only differentiate between "note hit" and "note missed", while other games (most Bemani games) have several levels of timing windows that award different amounts of points, or differentiate between a "close miss" and a "way off miss" by punishing you more for the latter. The exact width of these timing windows differs widely between games (and sometimes within the games), and you can guarantee that the type and width of these timing windows is a hot topic on forums where these games are compared.
 * Rhythm Heaven is a compilation of mini-games that are all hit-or-miss timing windows, but the windows seem to vary for each mini-game. Generally, the simpler the game, the harsher the timing window. Most of the games have either a near-hit or near-miss animation, but few if any have both. Not to mention the Space Shooter endless game that cuts down the timing window as you go.
 * O2Jam's timing windows are out of whack. First, the timing windows get faster as the song's BPM goes up. Second, they loosen when you use speed modifiers. Conclusion? You get punished if you're more comfortable with lower speed mods than higher speed ones.
 * DJ Max Technika also suffers from faster songs having smaller timing windows.
 * DJMAX Trilogy has the TECH stat, which expands the timing windows.
 * The GAMBOL Ascended Glitch in Beatmania IIDX deserves a special mention. Originally, it was one of the easiest charts in the game, but a bug caused it to have much tighter timing windows than any other song in the game, making it easy to clear but extremely hard to score well on it. The song has since been "fixed" to use the standard timing windows with the same chart on Normal difficulty, but retains its Hyper difficulty with the bugged timing windows, as well as having an added Another difficulty chart in the PS2 version of IIDX 11: RED, with the exact same chart but with ridiculously small timing windows that make it quite hard to clear. Newer installments in the series now have the "GAMBOL Judge Hyper" and "GAMBOL Judge Another" Easter Egg codes, which allow you to use the tightened timing windows on any song at all.
 * Fortunately, the latter incarnations of Guitar Hero allow you to manually synchronize audio and visuals with controller input. Rock Band 2 (and later) guitars have light and sound sensors that are used to precisely measure the audio and video lag.
 * The hit boxes in Guitar Hero and Rock Band are a point of contention among high-level players. In general, the timing window in Rock Band is pretty moderate, but the window shrinks when notes are placed very close together, which leads to Fake Difficulty on the hardest songs in the game (this is lessened in Rock Band 3, which has a new mechanic for extremely fast and\or imprecise strums and trills). Guitar Hero, on the other hand, is known for timing windows so big that "rhythm" is no longer a necessity. This is generally compensated for by including songs that are, for lack of better words, "walls of skittles".

Role Playing Game

 * This is part of what makes the infamous Cliff Racers of Morrowind so bad: the hitbox is misaligned so that it manages to both hit when it shouldn't and miss when it should have hit. Once you kill them the hit box still haunts you, as you need to remove the corpse to be able to grab anything near it or you will attempt to loot it's plumes instead.
 * Fortunately, getting below them and aiming for center of mass is pretty reliable.
 * Fallout 3 suffers this with the surrounding static models and their collision meshes. There are many occasions when one's line of shooting is very close to what is seen as an obstacle, but when one actually fires, they hit an invisible barrier, thus not hitting the target and subsequently alerting them to your presence and location if you were sneaking. The worst offender is the derelict subway car mesh.

In Melee combat, the range where you can activate VATS is longer than your weapon's actual range. You can effectively teleport about 10 feet to punch or chop your target. This is important since otherwise they tend to stay right out of melee range while retreating.
 * Fighting against other hunters in Phantasy Star Online is harrowing, as you need to land a blow directly in the center of their bodies in order for it to register...unless you're using a gun.

Shoot Em Up

 * Some Bullet Hell games (such as Esp Galuda) feature a tutorial at the beginning which, among other things, explicitly shows the ship's/character's hitbox. Usually represented by just a small circle in the cockpit/engine/torso and with a flashing arrow labeled "HIT".
 * The 'graze' mechanic in many Bullet Hell games involves two hitboxes- one very small (sometimes just a few pixels), which is fatal if struck, and a slightly larger one that gives extra points if bullets pass through it. This encourages players to take extra risks by getting closer to the bullets as they weave through the patterns.
 * Raiden DX has the graze bonus, despite being a non-Bullet Hell shooter with a ship-sized hitbox released in 1994.
 * Raiden Fighters brings the hitboxes closer to Bullet Hell-size, with the Slave having the smallest. However, if you're using the Judge Spear version of the Slave (which has the Judge Spear's game-breaking bomb), your movement speed becomes so fast that grazing becomes dangerous and impractical.
 * Raiden IV also downsizes the hitbox, to accomodate the denser enemy fire, and also has a grazing bonus.
 * In Border Down, the hitbox in the middle of the ship is small and enemy shots can pass through like other shmups. However, the ship will blow up if the ship itself, not the hitbox, runs into anything solid. Almost every other shmup these days will allow the player to put almost half of whatever they're playing as in walls and other obstacles as long as it doesn't hit the hitbox.
 * In Ikaruga, knowing the exact position of your hitbox is vital to getting the Dot Eater rank. Since you're not allowed to shoot your weapon for this rank, you have to be very precise in your positioning in order to get past walls, blocks, and enemies you're normally suppose to shoot to safely progress.
 * Radiant Silvergun has a mode you can unlock after playing enough hours where the hit boxes of your ship and the enemies become visible.
 * Knights in The Nightmare uses this version, awarding bonus experience for it.
 * rRootage and Parsec47, unusually, explicitly show the hitboxes of not only the player's ship, but also the bullets.
 * Genetos has a similar feature, but it's optional, because it can be distracting. It's off by default, but you can hit G to toggle it.
 * Both your ship and some asteroids in the original Asteroids had issues where they could appear to be hit on the side and survive, which makes this Older Than the NES.
 * The Japan-only Transformers NES game has this in spades. To begin with, enemy hitboxes are far larger than their graphics might suggest. On top of that, your own character is a large robot to begin with, and the game is extremely biased when it comes to hit detection - your own projectiles have to hit enemies dead center to hit them (and they're often very small to begin with) while enemy projectiles only need to barely graze you to score a hit. To make matters even worse, you're a One-Hit-Point Wonder that dies from Collision Damage while most enemies require multiple hits to kill.
 * Bangai-O Spirits has the Bat weapon, which has a hitbox larger than the range it swings through. This means you can swing at enemies a few feet away from your bat.
 * The Touhou series does this in a number of ways:
 * The playable characters' hitboxes are quite a bit smaller than their sprites. Focusing will show you it... except even that is a bit larger than it actually is, especially for Reimu, who has a smaller hitbox than everyone else (something that fans joke is a combat application of her power to eat sweets and never get fat.)
 * The bullets' hit-boxes themselves also tend to be tinier than their sprites (for example, you can safely fit the characters' entire hit-box into the sprite of the bigger bullets, or go through what seems to be a solid wall of rectangular amulets). This makes learning the hit-box of each type of bullet a important part of the learning process. There are, however, certain exceptions:
 * Patchouli's "Metal Fatigue" bullets are larger than normal for that type of bullet, greatly screwing up hardcore players that memorize exactly how large they normally are.
 * Knives have oddly shaped hitboxes that are larger than the sprite. Well, normally larger than the sprite. For some reason, later games have occasionally messed with the sprite to make it more accurate, while leaving the hitbox alone. They're still quite dangerous to players used to bullets having small hitboxes.
 * Mountain of Faith also has Kanako's extremely long oblong bullets during her first Spell Card attack, which appear to have rectangular hitboxes that make them absurdly big around the corners.
 * Enemies in general tend to have rectangular hitboxes that extend a bit beyond their sprite. This isn't normally a problem (in fact, it usually helps you, making it easier to hit them), except in Shoot the Bullet and Double Spoiler, where you're often required to get close to the boss.
 * Enemies' collision boxes are quite variable, though finding this out tends to be dangerous. While they're normally the same size as the enemies' hitbox, it been known to get smaller or disappear entirely during patterns that force you to get close.
 * But perhaps the most extreme example is the fanmade Mario knockoff, Super Marisa World, during the Kaguya battle. Damn, that's a small hitbox!

Simulation Game

 * Capital ships in the first Wing Commander have a bit of this going on, when at some angles of attack a ship's sprite doesn't quite match its actual physical model. This can result in blaster fire (or worse, missiles) passing clean through the enemy battleship.
 * The first two Wing Commanders (and spinoffs based on their engines) in general have a fair amount of this, as they simulated 3D objects flying freely through space by using sprites. The hitboxes are rectangular, no matter what the actual sprite looks like. This is especially noticeable when you are firing at a flat-shaped enemy fighter that is aligned diagonally, and you can hit it at the "empty" corners of the hitbox.
 * Some mechs in the Mechwarrior series have this issue on certain components. The Uziel in Mechwarrior Living Legends currently has a cockpit hitbox that is physically impossible to damage without splash damage, and many mechs in Mechwarrior 4 have odd hitbox locations, especially on asymmetrical mech. On the Cauldron-Born, the "Center Torso" hitbox is actually the projecting cockpit area, the Left Torso is only capable of being hit from the left side, and the Right Torso makes up the entire right side of the mech and can be hit from any angle.

Tabletop Games

 * At one point in Heroscape a model's cloak was not considered to be a hitbox. This had to be changed in later sets, as players were abusing the rules by turning their models cloaked backs to the opponent and claiming they were now immune to fire.
 * In Warhammer Fantasy Battle and Warhammer 40,000, a model's base is treated as its hitbox for purposes of melee combat, area effects, and such. The result is that, for example, a Gretchin (shrimpy little goblin creature) and a hulking Ork have the same hitbox, and a hitboxes may suddenly change (as when Terminators were moved from 25mm-diameter bases to 40mm-diameter bases.
 * Previously in 4th edition of 40k, for the purposes of shooting the Model was considered to be a cylinder, as tall as it needed to be for the purposes of being able to be shot at or not (so as long as you see part of the base, you saw the entire model). This was changed with the 5th edition, where True Line of Sight took place and you had to physically see the model in question. Problem is this causes massive issues since many players would model their commanders and characters on massively scenic bases, which would make them tall as hell. Moreover, the 5th edition introduced fliers, vehicles that are mounted on a massive clear pole on their own bases, which makes getting cover for them incredibly hard. It also caused the modelling community much headaches, as alot of aesthetic choices on the modeller's part are now against the rules, as it made the miniature physically smaller (and thus harder to actually hit) while others are being mothballed because they gave the model such height it was impractical to field them now.

Third Person Shooter

 * The N64 Mission Impossible game suffered from a quite disjointed hitbox, especially compared to GoldenEye. However, besides the common cases of bullets that should hit the enemy not having an effect, the biggest problem seemed to be with the individual hitboxes indicating the damage zone. The very common result of aiming anywhere besides the head was: the shot person would be shown flinching, but it wouldn't seem to have a damage effect, and a whole clip of a heavy pistol could be emptied into what seemed to be the lower half their center mass (or arms, legs, etc.), and then they would shoot back unfazed as you were reloading. This was even more jarring when you used what would otherwise be a One Hit KO dart gun, and was a major contrast to when you shot them in the head with even small handgun and they do a backflip. According to this author, "embarrassing... bullet detection problems" were also a factor in that game though.

Web Games

 * Skittles adgame Darkened Skye suffered from this in spades. The hitboxes on the enemies and the character's weapon were smaller than the sprites...and the character's hitbox was bigger. Leading to hilarious rage-inducing situations when you're flailing away at a little flying lizard and doing no damage at all, while it rapes you by clawing at the air a foot and a half away from you.
 * Very recently, Neopets released a game that, as part of a plot, was a re-skinned version of an older game. This is notable because the original game sprite was significantly smaller than the re-skinned sprite, but the hitbox remained the same. This was ostensibly a good thing... until you realize that the hitbox was the same size, but the center of it was located several pixels below the sprite itself, meaning that you had to fly higher than you thought you would to keep from dying. Bear in mind that this game is designed to constantly have your character descend unless you're consciously rising, so there's significantly more danger from scraping the bottom of the screen than the top to begin with...

Live Action TV

 * Came up as a plot point in an episode of CSI New York.
