How can I make some custom sounds for a weapon?
Go into your game folder where your desired weapon originates from (I’m going to assume Half Life 2). Go into sound and create a folder called “weapons” (minus the quote marks), then make another folder, for example pistol. Then add your wav file, it has to have the exact name as the original. You can get all the file names by using GCFScape.
Load Gmod and your sound will play when you’re done.
