Actually, you don't have to manually set bullet angle while spawning. Bullet will automaticaly get parent object's angle.
Heh, I thought it was supposed to be set. See this is why I like this here forums, you never stop learning and there is just so much info in here!
Simplifies this by a WHOLE bunch!
Just remove all the angle stuff and only have that "On Left mouse button Clicked" in there spawning a bullet at the "gunbarrel" image point... Awesome!
