Hi all!

I was wondering if anyone has every written a 2d skeleton-based animation system. I'm using joints, not bones, because I'll be needing only a few operations. Plus, it's easier to implement . Since I'm in the process of writing this system, any tips / code snippets / suggestions sure would be helpful

Also, I was wondering how physics would be handled in there circumstances. I'm using a physics engine as of now, so would I have to use a hitbox / create a physics shape for each joint? or would I need to use some other technique?

anway, thanks all!

Check out this thread - I attempted a 2D skeletal animation a month or so ago. Here are videos of its progress at various stages, in order from earliest to latest:









The end result (as far as I got) was pretty pleasing, but if you look at the earlier videos it might be easier to see how it was structured. Basically I used sine waves to determine the current position of each joint, relative to its parent.

Eventually I lost motivation because I realised the easiest way to progress would be to start again with 3D vectors, even if they were drawn in 2D. Depending on how sophisticated your animation is you might want to do the same. Consider the order in which body parts are drawn, especially if there is a turning animation.
