I am working on tool for 2D skeletonal animation. It exports all frames of skeleton to one file and images are animated, rotated in game. Which allows to adding different weapons/items to hand/armors etc.
Here is movie from it: http://www.youtube.com/watch?v=Ykv3jU6XZss
Currently I working with implementation for game maker, I optimizing it. When I finish I will move it to flashpunk and I think I will release this tool for free.
What do you think about it? Thanks.
