Animate Bone Layer Offset Script

[Mylenthes]

Im looking for a script that enables Bone layer offset to be animatable so i dont have to get off the bone layer.

I have a sword and i want it to be movable and angled with bones but right now it doesn't seem possible.

If there is a way to animate all in one bone layer without a script please tell me

Thank You

P.S im new

EDIT: LOL im a re-tard. If anyone wants to know all you have to do is move the bone with the move bone tool.
