Scripts which take an entity class or an entity class name as a string will require one of the following fields. Just use the name, not the number before it. For example, to make a spawner spawn disruptors, use ENTCLASS_PROJ_DISRUPTOR Spawning odd things like launchpads will probably crash the game.
