setWeaponReloadingTime seems broken. No arguments have any effect, neither before reloading or while reloading.
Furthermore, the wiki and the game has two completely different and contradicting descriptions of the command.
Wiki: "Sets states and/or makes an action of/on weapon. Reload time is between 0 and 1 inclusive, where 1 is 100% of maximum reloading time."
This would indicate that 0.0 is 0% of the configured reloading time (Thus 0 seconds), and 1.0 is 100% of the entire configured reloading time.
Game: "Set phase of weapon reloading. ReloadTime goes from 0 to 1, where 1 is the end of loading procedure. Return values tells if given weapon was found for given gunner."
This however seems to say that it sets the position inside the animation, and that 1 instant completion and 0 will play the entire animation.
