With this blueprint the projectile is spawned and moves to where my character is facing. I want to make it go backwards to where my character is looking, or move to the left or right. How do I make it happen?
If you right click the Transform pins, you can split them to expose each value. From there, you could just do some math on the yaw like so:
Put 90 or -90 in the addition node to go left or right, 180 to shoot it backwards. Or, any number really. Could feed an offset in as a float input on your shoot function or whatever.
