Hey all,
I’m having a wierd bug with a control rig I’ve made for a skeleton.
The image above summarised is:

  • I do a sphere trace from 10 units above the foot bone to 10 units below.
  • If the trace hits an object or the floor. It should check if the control for the foot bone is below said impact point, and move it up to the impact location.
    But once everythings plugged in. I keep getting an “Array Index(0) is out of bounds(0)” or bounds(1).
    No idea why its happening, please help.

Ignore the unllinked node for the -10 add. Thats linked. Tho doing so causes the array index error to spread to the the sphere trace node as well.
