Add-On Creation & Folder Structure

{{CatUp|Lua}}

= Introduction =
Add-Ons are one of the major components to Garry's Mod, because they allow users to easily add custom content to Garry's Mod in an easy, and organized way.
This page will teach you how to create your own Add-Ons that you can distribute to other players.

= The Info File =
The info file named "info.txt" is the key to making any Add-On work. Below I have shown the format of an Add-On file.

  "AddonInfo"
  {
     "name"                ""
     "version"             ""
     "up_date"             ""
     "author_name"         ""
     "author_email"        ""
     "author_url"	  ""
     "info"                ""
     "override"            "0"
  }

Then you just fill in the quotes with your Add-On's information.

= The Folder Structure =
An Add-On is just a folder with an info file inside it with content is their respective directories. For each piece of content you add to your Add-On, depending on the file type it needs to be added to a certain folder. Also, Add-Ons themselves should go into a certain folder. Below I have listed where each type of content should go. 

Note: $SteamUserDir is the directory in your steam file where game content is stored. Also, I will refer the name of your Add-On with an <addon-name> tag.

== Add-On ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/

== Lua (.lua) ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/lua

== Models (.mdl) ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/models

== Textures & Materials (.vtf, .vmt) ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/materials

== Maps (.bsp) ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/maps

== Sound (.wav, .mp3) ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/sound

== Data  ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/data

== Settings ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/settings

== Scripts ==

 ../Steam/steamapps/$SteamUserDir/garrysmod/garrysmod/addons/<addon-name>/scripts

= Conclusion =
some tend to think of the content of the folder containing "info.txt" as an extention of the "garrysmod/garrysmod" folder
