Determines random angle adjustment on hitscan weapons fired from player.
By default, hitscan projectiles (i.e. instant hit bullet projectiles such as SHOTSPARK1) do not have perfect aim; there is a random component to their trajectories. ANGRANGE is the xy part of this random component. ANGRANGE can be adjusted in EVENT_GETSHOTRANGE. When ANGRANGE is set to 1, the hitscan projectile will fire at the player's angle (perfect xy axis accuracy). Increase ANGRANGE by powers of 2 (2, 4, etc.) to increase the random angle and decrease accuracy. See also ZRANGE.
