Thread: Angle Compensation

As Moutere said, gravity only affects the horizontal component of the projectiles travel. If you are shooting 100m at 45 degrees up or down hill then the horizontal component is cos(45) * 100 = 70.7m, so it has the same drop as a 70m horizontal shot. This is an approximation as the projectile still slows as if it is travelling the 100m plus the extra deceleration of the vertical component of gravity sin(45) * 9.8 ms^-2, but these tend to be negligible over the distances we are dealing with.
