History Main / CollisionDamage

* This trope is prevalent in all of the ''VideoGame/{{Shantae}}'' games, ''VideoGame/Shantae2002'', ''VideoGame/ShantaeRiskysRevenge'', and one of the few modern games to play it completely straight. Monsters can hurt the player character on contact, while most of the time it's Shantae herself, but also the other playable characters as well (Like Sky, Bolo, and Rottytops in the "Friends To The End" mode in ''Half-Genie Hero''.

** ''VideoGame/ShantaeAndTheSevenSirens'': The Crystal Crab Monster Card gives Shantae the ability to break jugs by waliking into them, instead of using an attack to damage and break them instead.

* ''VideoGame/EccoTheDolphin'' and ''EccoTheTidesOfTime'': Ecco takes damage from enemy sea life. Somewhat justified considering jellyfish can have nasty stings and can even kill sometimes. Sharks do have sharp teeth and rough skin and crabs do use their pincers defensively. Also an npc dolphin tells Ecco that all sea life is frightened after the Vortex attack.

* Certain Franchise/{{Pokemon}} can have an ability (like Rough Skin or Iron Barbs) that damages any opponent that attacks it with a direct-contact physical attack, or causing a status such as poison (the Poison Point ability).

* In ''Manga/JoJosBizarreAdventure'', merely bumping into a Pillar Man can be fatal, as [[HalfTheManHeUsedToBe Mark]] finds out.

** ''VideoGame/SuperMarioBrosWonder'' adds some justification with new enemy animations such as Goombas biting the player character when they get close. However, it also leans towards the nonsensical with one situation; during your first encounter with Bowser Jr there will be a point during the battle where he will make you gigantic in size, and he will become very small. At this stage of the boss fight he is about as tall as your foot and realistically you should be able to just squash him underneath it. However if you happen to touch his very tiny body you will still be the one to take damage from him.

However, it also leans towards the nonsensical with one situation; during your first encounter with Baby Bowser he will at one point during the battle make you gigantic in size, and he will become very, very small. During this point he is about as tall as your foot and realistically you should be able to just squash him underneath it. But if you happen to touch his tiny body at any point you will still be the one to take damage from him.

* A booster cartridge (like the Game Genie or Knuckles) was once sold for the UsefulNotes/{{Commodore 64}} which eliminated sprite collision detection on any game plugged through it into the C64, making the player character effectively invulnerable.

* In the downloadable UsefulNotes/{{Nintendo 3DS}} game ''Witch and Hero'' and its sequel, both the player character and his enemies take damage when anything collides with them, and they take extra damage when attacked from behind. If the knight lands the killing blow on an enemy, he doesn't take any additional damage from attacking it.

* In ''SAS Combat Simulator'' on the UsefulNotes/AmstradCPC, upon starting the game, you were immediately swarmed by vast numbers of enemy soldiers. Your "SAS Commando" would instantly die if he touched one of them. (The fact that they also shot at you wasn't helpful either). However, part way through the first level, you could get a jeep powerup. Not only was this "jeep" a virtual tank, that made you immune to bullets, the collision-damage was reversed: now enemies died if they ran into you (even if you were stationary). But if you were hit by a grenade (or completed the level), you lost the jeep. This resulted in the most uneven difficulty curve ever seen.

* In ''VideoGame/FZero GX'', touching certain things in the course scenery will blow your machine up into pieces, even if the object is otherwise non-lethal to the touch or you touch it at a snail's pace.

** The Sonic Boost move introduced in ''VideoGame/{{Sonic Rush|Series}}'' and brought to glory in ''VideoGame/SonicUnleashed'' is a more precise example. Sonic's spin needs to watch the spiky bits of enemies, but the Boost goes straight through every unguarded enemy.
