Making projectiles

I need to set up a projectile attack for my player character and I have no clue how to do it. Can someone help?

Its extremely simple, use the EMIT function. Note that it will go different directions depending on the objects FORWARD property.

Positive force settings go the direction the character is facing.
Negative forces go the opposite direction.
if you use the flip command, the forward will go opposite, making the emit change too

can you make them emit in a vertical direction?
