Energy bar for Weapons

[singhamitoj]

Hello,
I was thinking if an energy bar for weapons could be added to the game. Weapons such as the flamer and shotgun would not be affected by this. However, weapons such as the energy sword and laser rifle (The sword uses energy and the rifle uses lasers) would be affected by this. Basically, instead of ammo (The sword doesn't have any, though) it would have an energy bar. While the energy bar is not empty, you can shoot without reloading, but when the energy bar is depleted, you have to wait for it to regenerate (The bar does not need to be full).
