Expression 2 Bone Core

This addon helps rotating bones using Expression 2!
Also it checks entity's owner, so other players can't move your or your entities bones.

Functions:

entity:setBoneAngle(number boneid,angle rot) - Rotates entity's bone with given ID
entity:getBonePosition(number boneid) - Returns vector position of entity's bone

Attached video shows, what you can do with these functions!
(Framerate on the video is poor, actually moving bones is very smooth)
