The SkeletonIK node shouldn't influence move_and_slide
, as it's a function in the KinematicBody node and there isn't any shared code or anything.
Is the KinematicBody node itself moving? If you use the remote inspector and check the position, does it change? Also, does the issue go away if you move the character using something like translate
instead of move_and_slide
? It will not have collision, but it might help answer if the movement is of the node itself is causing the issue.
