How does it work? i'm trying to cannibalise the code to generate another item, i've already altered everything but i can't see how it works when you place it.

It's not controllable like the clone farm, at the moment i'm thinking about giving up and using that as a base because this isn't working

So basically, is it controllable?

It's not controllable, it's just an emitter. Thing is, it's missing the code that actually makes it emit. Try throwing a EmissionEnabled = 1 somewhere in there, and if that doesn't work, compare the code to another emitter, like a wound, to see what else is missing.

It's controlled by the .lua file for the scene, and as such does not work outside of the zombie cave mission run from the campaign menu.

You can take the sprite and throw an emitter on it that creates zombies, though. Might require the "abomb" method to make them function properly, though.
