I feel like a hammer noob again.
I have a problem with an energy ball launcher, which is that the ball is going in the wrong direction. I have no idea what is causing this. the pitch yaw roll is set in the correct direction, the point_energy_ball_launcher is not touching anything (It is not even in a dynamic model), but yet it goes at an obscure diagonal angle. Does anyone know what My problem would be?

Edit: My map does not have leaks, either.

I honestly don't know ( i don't have hammer you see ) but i think this problem might not have been encountered, in which case your name goes into history

I am not sure if this might be helpful.... but if there is an entity (or block) that spawns launcher (i only managed to make little bit of map in Hammer) try to rotate it 180 degrees so it faces the way you want, i had a similair problem when i set up the "Starting bed" effect, in which the camera went the oppsoite direction than what it was suppose to be, and i realised that the entity (or block) was placed and should've been rotated.

No, that wasn't my problem. I found out eventually that my ball spawner was clipping into the side of a model, causing the ball to spawn then bounce off.
