Having problems with component rotation. please help

I am making a missile truck(likes MLRS)

and i want the launcher part of the truck to rotate.

How can i do this? if i rotate the component, the collision does not seems to rotate.

a object passes through the rotated launcher.

Answer Please!

I think it should normally be rotating by default. you can turn ‘show collisions’ on to confirm that’s what is happening. i think the keyboard shortcut was alt+c.

unless your using a separate volume for your collision, your collision should always move with the mesh. if you are using a separate volume for collision then just make the volume a child of the mesh. in any event pictures would be helpful and a bit more info like how you are doing your rotation and what objects are passing though it.
