.smx file to /cstrike/addons/sourcemod/plugins/ and any translations, gamedata or configs files to the matching folders under addons/sourcemod/. Then type sm plugins refresh in the console or change the map. Check it with sm plugins list. SourceMod must be installed first.
Before you start
- Install Metamod:Source and SourceMod. They are not preinstalled.
- Get plugins from the AlliedModders plugin list or the author’s GitHub. Check that the plugin supports Counter-Strike: Source.
- Make a backup before adding several plugins.
How to install a plugin
1
Download the plugin
Download the compiled
.smx file. If the author only offers a .sp source file, you need a compiled .smx; the server can’t run .sp files.2
Upload the .smx
In Files, open
/cstrike/addons/sourcemod/plugins/ and upload the .smx.3
Upload extra files
If the plugin comes as a zip with
addons/sourcemod/... inside, upload the zip to /cstrike, click … and choose Unarchive so every file lands in the right folder. Otherwise copy each folder by hand:4
Load it
In the console, type
sm plugins refresh. A map change or restart also loads new plugins.5
Check it
Type
sm plugins list. Your plugin should be in the list without an error.6
Configure it
Many plugins create a config file in
/cstrike/cfg/sourcemod/ the first time they load. Edit it, then change the map or restart.Plugin commands
How to turn a plugin off
Move the.smx into /cstrike/addons/sourcemod/plugins/disabled/ with Move, then change the map. To turn it back on, move it back into plugins/.
SourceMod also keeps some optional plugins in plugins/disabled/, such as map voting plugins. Move one into plugins/ to use it.
Why a plugin doesn’t load
Plugin errors are also written to
/cstrike/addons/sourcemod/logs/.
Frequently asked questions
Can I install CS:GO or CS2 plugins on CS:S?
CS2 plugins (CounterStrikeSharp and similar) don’t work on CS:S. Many CS:GO SourceMod plugins don’t either. Use plugins that list Counter-Strike: Source as supported.Do plugins need a restart?
Usually not.sm plugins refresh or a map change loads them. Plugins with extensions or gamedata may need a full restart.
Where do plugin settings go?
Most plugins use a file in/cstrike/cfg/sourcemod/ or a cvar you can add to server.cfg. The plugin page tells you which.
