You will need to know where your Gmod common folder is. Many other guides reference how to get there. For me, I go to C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod.

Once you reach this magical place, go to your gamemodes folder. This method of modifying your files is gamemode specific, so select the gamemode you want to modify. I will be modifying my Sandbox files, because each gamemode overrides the base settings.



After you do that, go to your gamemode/player_class folder. You will now need to open the player_class lua file with notepad. This is where you can start modifying files.

Once you open the file, it should look something like this:


These are the variables I know how to change:

PLAYER.WalkSpeed = 400 -- How fast to move when not running
PLAYER.RunSpeed = 600 -- How fast to move when running
PLAYER.CrouchedWalkSpeed = 0.3 -- Multiply move speed by this when crouching
PLAYER.DuckSpeed = 0.3 -- How fast to go from not ducking, to ducking
PLAYER.UnDuckSpeed = 0.3 -- How fast to go from ducking, to not ducking
PLAYER.JumpPower = 200 -- How powerful our jump should be
PLAYER.CanUseFlashlight = true -- Can we use the flashlight
PLAYER.MaxHealth = 100 -- Max health we can have
PLAYER.StartHealth = 100 -- How much health we start with
PLAYER.StartArmor = 0 -- How much armour we start with
PLAYER.DropWeaponOnDie = false -- Do we drop our weapon when we die
PLAYER.TeammateNoCollide = true -- Do we collide with teammates or run straight through them
PLAYER.AvoidPlayers = true -- Automatically swerves around other players
PLAYER.UseVMHands = true -- Uses viewmodel hands

To add a variable that isn't there, simply paste one of the above directly underneath the last PLAYER variabe there. For me, I will be placing WalkSpeed, RunSpeed, CrouchedWalkSpeed, and DropWeaponOnDie under PLAYER.UnDuckSpeed.

As you can see above, I changed some of the variables to my liking. You should probably test out your new settings in singleplayer before you create a listen server.

If you scroll down a little bit in the player_class document, you should see something like this:

The upper area of the screenshot shows the ammunition and guns that are given to you when you enable weapons (all hl2 weapons in this case), and the bottom area shows the ammunition and guns that are given to you reguardless (the toolgun, physgun, and camera in this case).

To add a weapon and its ammo to this list, you must know the weapon and ammo "script" name. To find that, go into Gmod and right click the weapon you want. Select "copy to clipboard" and paste its name somewhere you can get it. I will be doing this with FA:S weapons.

The IMI Galil's "script" name is fas2_galil.
The IMI Galil's ammunition "script" name is fas2_ammo_556x45

Next, just copy over the names to repace the ones there. You can remove lines if you want, but make sure to copy them exactly if you want to add lines.

Hopefully this helped you in setting up a server. This works with both dedicated and listen servers, you just need to find their respective file paths.

If you need individiual loadouts for each person, I recommend this addon:
