How do I make gun rotate only 180 degree

I am using the "Set angle toward(Mouse.X, Mouse.Y)" action to move the gun.However i want the gun to move only 180 degree max so that the gun don't do behind the chassis.How can i do this ?

I looked at your project, I think maybe if you make an invisible object that has follows the Y position of the mouse always but only follows the X position of the mouse if it is in front of the truck. Then have the turret point at this object instead of the actual mouse position.

— i am using the r233 version of construct and hence i cannot open your example

Although on second thought, you might want to be able to aim at all times..so this works for reversing the angle of the gun...

Works perfect plinkie....Thanks
