(I'm using blender 2.59 game engine ,my game character must aim and walk or jump and more action )
problem : aim-action don't work, holding the right mouse button the character must aim up down When the gun comes out and stop aiming when the gun back. problem 2: he keep aiming!. I think changed the script will solve the problem but I'm a beginner in script, I do not know where I start!.

Thank you in advance for the help.
