eli5: In a video game, why is it so hard to create hit boxes? And why aren’t they exact copies of the character model?

591 views

Hopefully this hasn’t been asked before on this sub, but I was wondering why so many games struggle with good hit boxes? Why are they even “boxes” in the first place? I would assume they would just be carbon copies of the character model instead of having individual boxes that stretch out over the characters body.

Checking for collision against a box around the player is quick and easy. Precise? Naw, not really – but gives you a result, either hit or miss, really quickly.

Checking for collision against *every individual part of a model* is slow. Slower “decisions” on things like hits or misses are extremely undesirable.
