All (action)games I know of don’t have real and proper surface collision detection, except some physics games. Just an example: If my Char hits something or someone the weapon goes straight through without any physical reaction, it just counts the damage I’ve done. Are there any games out there, in which physics are calculated correctly and taken into visual account?!
Plenty. It’s just that it’s not often used because it’s more computationally expensive.
Usually it’s just collision hulls for hitboxes instead of per-face collision. But even if your sword passes right through the enemy, it’s still doing collision detection to identify that it’s passing through the enemy. It’s just that animations are rarely complex enough to account for all the possible ways you could hit an enemy.
