ive looked through the tutorial on how to set the direction i want the energy ball to launch in, but i cant find a keyvalue "angle" or "direction". how do i do this?
when I launch the ball, it just bounces in random directions.

edit: also, how do i get rid of the actual ball after it hits the catcher?

For the first part.. no clue

As for the second question, to get rid of the ball, on the outputs of your catcher, have it disable your launcher.

i did that, but it just has the ball keep bouncing around

You can change the angle in the point_energy_ball_launcher entity. The keyvalue is Pitch Yaw Roll (Y Z X).

In the trigger_once/trigger_multiple in the catcher, add this output:

OnStartTouch > !activator > Kill
