No, I changed my mind : I tried to make the HD pack addon compatible with this, but the TAU cannon angles are messed up.

Modified the Gauss gun for NPCs 'cus why not

Added new weapon special for NPCs in override list if u mount Half-Life: Source. It adds the TAU cannon itself! (WARNING: Code retaken from the MekoTAU cannon)

Added damage type. (DMG_ENERGYBEAM)

Reorganized lua, and now the weapon use only its own lua file instead of shared.lua, cl_init.lua and init.lua

Disabled Accurate crosshair for fixing the zoom glitch.

Reactivated the NPC script at the end of the lua file. This way it's already updated for the GMod update.

You can no longer spam RMB now.

SWep is now usable by NPCs. Expect another update when the GMod update is released.

Reorganized and optimized some codes in shared.lua .
Also buffed the RMB recoil to fits like on Hl:Source.
