I’m looking to implement something like this, only the game will adjust the bezier curve points at runtime.
I know that the path constraints work but I’m not sure about dynamically updating the constraint points of a path at runtime if that is supported currently.
You can use IK constraints with path constraints and I think that should work though. May take some experimenting.
Weight path to IK, constrain bones to path, and weigh mesh to bones.
Make sure you test with Spine version 3.7.94
Support for the official Spine runtime is a possibility on the horizon.
