Hey DreamBotStudios,
If you figure out the Forward Vector you would fire in, as in to fight to the right side of the screen, you can then take that same vector and feed it into the Rotate Vector function which will let you quickly get, for example, the new vector if you rotate X by -45 degrees (or 45 degrees). You can then use the new vector to generate the velocity in which to fire another projectile. Here’s a sample node setup for Rotate Vector:
Hope that helps!
