How do I set the bullet direction?

When i shoot the bullet go to the oposite side of my gun, what do i do, how do i set the the bullet direction to shoot for the right not left?/

(sorry for my english, i know it suck)

Set the Bullet "Angle of motion" in the direction that you want it to go.

Normally if the bullet's default Angle is looking to the right then you set it to:

Angle of motion = 0

To move in the right direction

thank you that work.
