I'm prototyping a 2D platformer/brawler game for uni and I'm having some trouble with creating collision/bounding boxes. This is most likely going to end up on a Vita so I do have some library constraints as well as performance implications. None of this has yet been implemented but is all theory. My idea was to have the artist create a sprite sheet for the character animation and then a second identical sprite sheet with the corresponding collisions in a solid colour (e.g green for where the character can be hit and red for dealing damage, near the foot if kicking etc.) With this, I would then parse the collision sheet and generate the various collisions required storing them in the character model. This is the point I feel would be most inefficient. While I think this is a possible solution, I was wondering if there was a more standard way of doing this or a more efficient way as I feel this would have severe performance problems.
