Ball Throw

I’ve got a simple First Person sports game I’m working on, and right now any help would be greatly appreciated.

What I need help with is to blueprint in a simple ball throw. Right now I’ve got it set up so a character can pick up the ball, and he can sort of throw it, but the real problem I’m having is just having him throw it straight. Right now it just sort of pops out of the character in random directions.

I’m sure the problem is I just don’t understand math all that well, but here’s a screen cap of what I have going on. The area in yellow is the Ball Throw. And I’m pretty sure the problem lies with the Add Impulse. Because really that section should just be getting a forward vector for my character, I guess I’m just unsure on how to handle that.

Thanks a bundle!
