SourceMod is the plugin framework most server plugins need. Game Host Bros installs it for you on your Black Mesa server, together with Metamod:Source, with one setting.

How To Install SourceMod

1
Log in to Bropanel and select your server.
2
In the sidebar, go to Settings.
3
Under Modding, enable SourceMod.
4
Click Save & Restart to apply your changes.

While Auto Update is on, SourceMod and Metamod:Source update to the latest stable version when your server restarts. Your plugins and their configs are kept.

Note

If you want to install a specific SourceMod or Metamod:Source version yourself, keep this setting off so our system leaves those files alone. Turning it off moves our managed addons folder aside as addons_disabled_ plus the date, so nothing is deleted.

Adding Yourself As An Admin

1
Join your server, open the console and type status to find your SteamID, for example STEAM_0:1:12345678 or [U:1:12345678].
2
Log in to Bropanel and select your server.
3
In the sidebar, go to Files and open bms/addons/sourcemod/configs/admins_simple.ini.
4
Add a new line with your SteamID and "99:z", for example "STEAM_0:1:12345678" "99:z", and save the file.
5
Restart your server.

In game, type sm_admin in the console to open the admin menu.

How To Install Plugins

1
Log in to Bropanel and Stop your server.
2
In the sidebar, go to Files.
3
Navigate to bms/addons/sourcemod/plugins.
4
Upload your plugin files, usually ending in .smx.
5
Start your server.

Use plugins made for Black Mesa or for any Source game. Some also need an extension in bms/addons/sourcemod/extensions or a config in bms/cfg/sourcemod; check the plugin's page for what it needs.
