for some calculations having the end of the muzzle is extremely helpful:

syntax:

unit muzzlePosition muzzleName

Example:

player muzzlePosition primaryWeapon player

The return value can either be ASL, AGL, or in model coordinates.

Alternatively, we could have a weaponMemoryPointToWorld command that supports custom selection names:

player weaponMemoryPointToWorld [primaryWeapon player, "usti hlavne"]

(the shorter the command name the better!)
