Blender Game Logic Actuator I managed to be able to control my player hand with mouse using mouse actuator.However, the hand move at the opposite direction i want. For example ,  when i move mouse down , the hand go up .And when i move my mouse around , the hand kind of turn around .



What is wrong with my actuator settings?
Here is the sample file:   http://www.mediafire.com/download/1sz9taf3bd8j28u/samp.blend
to reverse the hand direction set the sensitivity to -1.0 :



also pay attention to the local/global axis you are using ,the camera was turning in the right direction because you used the local axis while the hand local axis are not in the right orientation
