I made an animation that is supposed to swing a sword, etc.The code and animation is fine, but when I play the animation, everything moves except for the arm holding the sword. Is there something I have to tweak in the properties? All the parts are unanchored.
When you create the animation you must set the priority. Set the priority to ACTION. That overrides all other animations including the default tool animation.
I have had that same problem. When creating the animation keep in mind only r15 block rig animations will work on r15 only. And r6 animations will only work on r6.
