I just realized that imported Spriter models don't have bounding boxes/collision shapes and that GetSpriteHit is returning 0 when Spriter model is touched (with GetPointerPressed). Since Appgamekit is not giving me access to Spriter atlas/textures, I need help how to make these files identified by touch/collision.

limited experience with skeletons but based on this comment, i think your best bet is to create a sprite and attach it to the skeleton, somehow.

when i attached a 100x250 sprite to the skeleton in the Spriter example via FixSpriteToSkeleton2D(), i experienced some visual anomolies with the "collision" sprite (including a visible CreateDummySprite() sprite that was NOT the 100x250 i set it to):

..but the sprite registered proper hits, regardless. unknown what caused the visuals... there's some scaling and offsetting going on somewhere.

manual placement of the collision sprite based on GetSkeleton2DX/Y worked normally, of course (and i didnt try box2d methods which would allow additional sprite shapes, etc).

anyway, that's where i would start.

Thank you very much for the tip!


I also found strange anomalies while working with Spriter models on percentage-based screen layout where Spriter texture is abnormally stretched on 1.33 aspect ratio screen.
