<cat>Play.Hosting</cat> The convar **sv_loadingurl** allows a server owner to define a webpage to show to players when joining the server. # Setting your server's loading URL If you are setting the convar through the console then make sure to put quotes around the URL. Also a + should be added to the front. Your command should look something like this: ``` +sv_loadingurl "http://wiki.garrysmod.com/" ``` If you are placing this into your autoexec.cfg configuration file, be sure to remove the +, like so: ``` sv_loadingurl "http://wiki.garrysmod.com/" ``` If you want, you may also use %s or %m in your URL (most likely in a GET variable) to pass the steam id, and map name respectively. For example: ``` sv_loadingurl "http://wiki.garrysmod.com/?mapname=%m&steamid=%s" ``` These can be later retrieved with simple PHP code. # Custom loading pages This section will not detail creating your page, and assumes you have already designed one. ## Javascript functions There are several Javascript functions which are called directly by Garry's Mod. To use these, simply create a function with that name in your page - it will be called when the event associated with it happens. ``` /* Called at the start, when the loading screen finishes loading all assets. serverName - Server's name. Convar: hostname For exmaple: "Garry's Mod Server" serverURL - URL for the loading screen. Convar: sv_loadingurl For example: "http://mywebsite.com/myloadingscreen.html" mapName - The name of the map the server is playing. For example: "cs_office" maxPlayers - Maximum number of players for the server. Convar: maxplayers steamID - 64-bit, numeric Steam community ID of the client joining. For example: 76561198012345678 gamemode - The gamemode the server is currently playing. Convar: gamemode For example: "deathrun" volume - The value of the player's in-game 'snd_musicvolume' console variable (Music Volume), from 0 to 1 language - The value of the player's in-game 'gmod_language' console variable, a two letter representation of the player's main menu language */ function GameDetails( servername, serverurl, mapname, maxplayers, steamid, gamemode, volume, language ) {} ``` ``` /* Called at the start total- Total number of files the client will have to download. */ function SetFilesTotal( total ) {} ``` ``` /* Called when the client starts downloading a file. fileName- The full path and name of the file the client is downloading. This path represents the resource's location rather than the actual file's location on the server. For example, the file "garrysmod/addons/myAddon/materials/models/bobsModels/car.mdl" will be: "materials/models/bobsModels/car.mdl" */ function DownloadingFile( fileName ) {} ``` ``` /* Called when the client's joining status changes. status- Current joining status. For example: "Starting Lua..." Under normal conditions this would not be fired until game client starts interacting with server files/workshop. This means you probably can't use "Retrieving server info" and everything that goes before downloads. */ function SetStatusChanged( status ) {} ``` ``` /* Called when the number of files remaining for the client to download changes. needed- Number of files left for the client to download. */ function SetFilesNeeded( needed ) {} ``` ## PHP GET parameters **%m** and **%s** will be replaced with the server's current map and the player's 64-bit steam community ID, respectively. This means you can grab them using PHP's $_GET superglobal. The map is a string, so you should have no trouble making use of that. However, the steam community ID is not the classic "shorthand" steam ID often seen in-game. A method of conversion (using PHP's bcmath & bcsub) is shown below. <note> Method from http://maurits.tv/data/garrysmod/wiki/wiki.garrysmod.com/indexb59e.html --please notify if this doesn't work</note> ``` <?php $authserver = bcsub( $communityid, '76561197960265728' ) & 1; //Get the third number of the steamid $authid = ( bcsub($communityid, '76561197960265728') - $authserver ) / 2; //Concatenate the STEAM_ prefix and the first number, which is always 0, as well as colons with the other two numbers $steamid = "STEAM_0:$authserver:$authid"; ?> ``` <example> <description>If you would like to use a local file as a loading screen, for example during gamemode creation as a default loading screen, you can use the asset:// prefix. The example uses the default loading screen, but any html file can be used.</description> <code>sv_loadingurl "asset://garrysmod/html/loading.html"</code> </example> <example> <description><validate>We Seek Validation, does it work?</validate>If you would like to use a simple image as a loading screen, but don't have a webhost, you can use the following code as your `sv_loadingurl` value. Make sure to replace `URL-GOES-HERE` with the link to the image you would like to use. This makes use of [Data URIs](https://developer.mozilla.org/en-US/docs/data_URIs) for writing HTML for the URL.</description> <code>data:text/html,<style>html,body{padding:0;margin:0;background:#000}</style><img src="URL-GOES-HERE" width="100%" height="100%"></code> </example> # Ready to use examples ## gmod-lsm.com A free, online and easy-to-use loading screen maker, without having to code anything or rent a web server.
