I have a aim animation playing when i press right click, i put a IK on my lower back of the armature.
The parent is a empty and when i move the empty the lower back moves but not that far 
the aim looks up and down but i want to control this in real time, i using a mouse actuator
but like i said, it does not work well and the empty does not seem to
make the bone look up or down that far, is there any way around this. I will upload a demo later.
