Addons Guide/Step Two: Installing

From GMod Wiki

Garrysmod.org is a the official website for Garry's Mod addons, with a large selection that is checked to insure there are no viruses. You'll need to sign in with your Steam account to quickly verify you own Garry's Mod before you can download anything from the site.

Installing Addons

Standard Download

• Download your addon of choice from the internet to a sensible location on your computer. Our example addon here will be ADDON.zip.

• Extract the addon from its .zip or .rar file using either Windows inbuilt extract wizard or a program like WinRAR. You'll end up with a folder, in our case called ADDON, with several subfolders entitled Lua, Models, Materials, etc.

• Go to your addons folder

• On 32-bit Windows, your addon folder is located at C:\Program Files\Steam\steamapps\USERNAME\garrysmod\garrysmod\addons\
• On 64-bit Windows, your addon folder is located at C:\Program Files (x86)\Steam\steamapps\USERNAME\garrysmod\garrysmod\addons\

• On Mac OS (X), it is located at Users\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\addons\

or Finder\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\addons\

• Copy the downloaded folder (in our case ADDON) into the addons directory. Make absolutely sure that if you open the folder it will have the following in it: Lua, Materials, Models, etc, and a Info.txt file.

• If there is no Info.txt file you can easily create one using notepad:

"AddonInfo"
{
        "name"              "Addon name"
        "version"           "Current Version"
        "up_date"           "Date of update"
        "author_name"       "Addon's Author"
        "author_email"      ""
        "info"              "Addon's Info"
        "override"          "0"
}

• With all these files in place, your addon is installed and ready to use!

SVN Download

Some addons are only available through something called SVN. It is simply a way to share files.

• Download a suitable SVN client. TortoiseSVN is the one this tutorial is written for.

• Find your addons folder

• On 32-bit Windows, your addon folder is located at C:\Program Files\Steam\steamapps\USERNAME\garrysmod\garrysmod\addons\
• On 64-bit Windows, your addon folder is located at C:\Program Files (x86)\Steam\steamapps\USERNAME\garrysmod\garrysmod\addons\

• On Mac OS (X), it is located at Users\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\addons\

or Finder\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\addons\

• Depending on the instructions given, either create a folder (for example ADDON) inside the addons folder and right-click on it, or just right-click on the addons folder itself.

• From the right-click menu, select "SVN Checkout".

• Type the SVN address (for example: https://svn.wiremod.com/svn/wiremod) into the first text box and type the full address of your addons folder (see above) into the second.

• Some SVNs require a username and password. These should be available from the download's relevant website.

• When it is done downloading, you can delete the .svn file in your "addons" folder.

• Every so often, right-click on your "addons" folder and select "SVN update" to check for updates to your SVNs.

Installing Maps

Installing maps is even easier than other addons.

• Download the map of your choice. Our example here will be MAP.zip.

• Extract it from its .zip or .rar file using either Windows inbuilt extract wizard or a program like WinRAR. You will have a new folder, in our example entitled MAP.

• Within this folder will be a file named MAP.bsp.

• Go to your maps folder

• On 32-bit Windows, your maps folder is located at C:\Program Files\Steam\steamapps\USERNAME\garrysmod\garrysmod\maps\
• On 64-bit Windows, your maps folder is located at C:\Program Files (x86)\Steam\steamapps\USERNAME\garrysmod\garrysmod\maps\

• On Mac OS (X), it is located at Users\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\maps\

or Finder\USER\Library\Application Support\Steam\SteamApps\USERNAME\garrysmod\garrysmod\maps\

• Copy the MAP.bsp into the maps folder.

• You now can select your new map from the New Game dialog in-game. If you continue to have problems, see the full Installing Maps page.
