PROJ RANGE
When PROJ_WORKSLIKE is a hitscan type projectile (PROJECTILE_FLAG_KNEE or PROJECTILE_FLAG_BULLET) this number must be equal to the desired range in BUILD units. If PROJ_WORKSLIKE is an RPG type (PROJECTILE_FLAG_RPG) this number is amount of time (in ticks) that a projectile travels before expiring. For example, if a projectile has a range of 52, then it will last for exactly two seconds before dying.
For RPG projectiles this works together with PROJECTILE_FLAG_TIMED and PROJECTILE_FLAG_EXPLODEONTIMER.
