An RPG or perk mod for Left 4 Dead 2 is a SourceMod plugin that gives players experience, levels, points or perks for kills and objectives. To add one, install Metamod:Source and SourceMod, upload the plugin’s .smx and its other files to addons/sourcemod/, and, if the plugin saves player progress in MySQL, create a database in the panel’s Databases page and add it to addons/sourcemod/configs/databases.cfg.

​
Before you start

  • Install SourceMod and, because most L4D2 plugins need it, Left4DHooks.
  • Pick an RPG or points plugin on AlliedModders and read its requirements: SourceMod version, other plugins, and whether it uses a database.
  • Make a backup in Backups.

How to install an RPG plugin

1

Upload the plugin files

In Files, upload the .smx to left4dead2/addons/sourcemod/plugins/. Put gamedata files in gamedata/, translations in translations/ and configs in configs/, as the plugin’s instructions say.
2

Restart once

Restart the server. Most plugins create their settings file in left4dead2/cfg/sourcemod/ on the first start.
3

Check it runs

Type sm plugins list in the Console. If the plugin shows an error, open the newest errors_<date>.log in addons/sourcemod/logs/.
4

Adjust the settings

Edit the plugin’s .cfg in cfg/sourcemod/ (XP rates, prices, perk limits) and restart.

​
How to connect the plugin to a MySQL database

Plugins that save levels between sessions need a database.
1

Create a database

Open Databases in the panel and create one. Note the host, database name, username and password it shows. See how to manage databases.
2

Edit databases.cfg

Open left4dead2/addons/sourcemod/configs/databases.cfg and add an entry inside "Databases" with the name the plugin asks for (here myrpg):
3

Restart

Restart the server and check the SourceMod error log for database errors.

​
Frequently asked questions

​
Do players need to download anything for an RPG mod?

Usually not. Most RPG plugins run on the server only. Check the plugin’s page for custom sounds or models.

​
Can I use SQLite instead of MySQL?

Some plugins support SQLite, which stores data in a file on the server. Use whatever the plugin documents; MySQL is easier to back up and view separately.

​
Why did all levels reset?

The plugin couldn’t reach its database, or it stores data in a file you deleted. Check the error log and databases.cfg, and restore from Backups if needed.
