ConVars

ConVars are made to dynamically change the settings of the server: So you should add these ConVars (with modified names!) to your custom class addon

ConVars

CreateConVar("ttt_customclasses_enabled", "1") [SHARED]

This can be used to enable/disable the class selection.

CreateConVar("ttt2_classes_shooter_enabled", "1") [SHARED]

This will be automatically initialized
