In the last section of the manual it says:
"When you wish to add your own custom Player control without affecting the other scripts, it's
recommended that your Player prefab uses the Mecanim engine for animation, so that you can
script parameter changes without intefering with the other systems".
Based on that I tried to integrate character system 5.1 to AC but after several weeks of atemps I gave up. Can anyone give a hint of how to do it or if you think it's possible to do it with that system or any other alike?
