Yes, its true that changing ball´s tilt will change the trajectory

actually that is the problem, because ball´s tilt is allways camera tilt and works fine with player and gun stopped, i mean, the ball is created right and the movement and gravity is good, no matters what pan ot tilt camera / gun.

The problem is when the player and gun are moving, if i look up the ball is trown too much high, and when look down she goes too much down.

Tried using player´s speed on ball´s movement but didnt work

More ideas?
