Hey everyone, I can’t believe I am having this problem. I have had it before and managed to fix it. But can’t remember how. 
I have and empty that shoots a missile. The Empty is parented to the tip of a rocket launcher. Which is set to track to my character. However, even though the the rocket launcher is tracking to my character, the rocket only shoots one direction. Even if the empty is aimed sideways, it still only shoots the same way.
I know it’s easy to solver, because I have had it before. Hoping for some answers.
Thanks,
~Coonerboy.
p.s did I explain that clearly enough?
Check that the missile is set to move along it’s local axis rather than the global axis. If the add object actuator controls the missile movement, make sure that it’s set to local (little L button), if the missile is moved by a motion actuator check that’s set to use the objects local axis.
Hope this helps!
