How to make Bones2D follow a Path2D

dbt79

Hello, I want to animate a snake though a predefined Path, using an Skeleton2D&Polygon2D for the snake and a Path2D and PathFollow2D to make snake move. The objective is that the bones of the snake adapts trough the path.

Snake polygon2D is properly rigged and weighted, but, when I make the snake (skeleton and polygon with child bones) child of the node Pathfollow2D, the bones don't follow the path.

What I'm missing? How can I make all the bones follow the path properly?

Welcome to the forums @dbt79!

You will probably need to have multiple PathFollow2D nodes, one for each bone, offset correctly in the path. That would likely be the easiest way to handle the problem. You could also write a script that rotates the bones based on the head's change in rotation, at least in theory.

The problem I see is that a Bone2D has to have another Bone2D or Skeleton2D as parent, and PathFollow2D has to be child of Path2D. I don't know how to get to the way you say, with multiple Pathfollow2D being parent of Bones, that don't work if not set as child of another bone or skeleton...

I think I'll have to use a script to set bones positions related to different Pathfollow2D with offsets, I just thought it would be an easier way.

You'd probably need to use RemoteTransform2D nodes, but using a script is probably the most flexible solution.
