I wan't to make a tank type thing, but i'm having trouble with something i'm guessing has to be really simple, but i can't seem to solve it.
The cannon moves freely. But when i'm moving the base and not the cannon, I want it to maintain the angle it had, relative to the angle of the base.

It's like what the pin behavior does, but i wanna know the math =(
