WHICH ACTUATOR DO I USE???!!!!

ive been trying to make a fps, but i cant figure out withc actuator i use to make the gun follow the cursor… Sugestions welcome pleaaaaaaaase

…thanks

the ipo actuator… duh

[to do proper fps controls in blender you MUST use python [there is no way to tell how much the cursor has moved without python, and even if there was there’s not anything useful you can do with that with only logic bricks]. The camera can be rotated with IPOs [a parent object for left/right, and the camera itself has another ipo to look up/down] or you could use setOrienation [with a 3 by 3 rotation matrix]. Your gun should be the child of your camera…]
