IK in 2D: tests


Some tests of using skeletons and IK. I've always used skeletons and IK in 3D softwares and it was new for me find and use these tools in a 2d software. To understand better how they work I quickly sketched a posing puppet, every moving section of the body is a different level (object) for the software, and then I built a skeletal stucture for the puppet, parenting and linking all the objects. Then was the the time for animating everything using FK, IK and mixing them.
It seemed to work smoothly, you can even make a clone of the puppet mirror it and all the animations were mirrored in the right way. But then there was to test what could happen if translatig the skeleton and while changing the root of the IK chain while the root of the skeleton was a different join bringing the overall translation data: so another little test with the puppet making a lateral step.
