Is there any link telling you how to create a RTS game with UDK ?

including constructing Buildings through your mouse trace. i'd like to use the same system

But basically , Place a Static Mesh , or any 3d Model , when you click the mouse button, where you aiming of couurse with that green transparent house , and red when you cannot place it , That wouldn't call start fire anyways?

well since you cannot change input during runtime , then you need a weapon in order to do that ???

because that click would call the startFire function want it or not, so you'd need a hammer or something help
