How to make a resource generator?

[WolfClaw114]

I want to add in an object into my mod which will create resources over time e.g. food, water, ammo ect.
I assumed i could alter a water purifier to produce something else but that ended up not working, didn't even see a reference for purified water within it. 

Is there another way, or tutorial i somehow missed which goes through the process of creating a resource generator?

F4MS Factory was written to do this.
There is a demo mod showing how to use it.

The water purifier uses an actor value so it knows what to produce.  Most of the stuff in settlements that produce resources use either keywords or actor values to let it know what to make.  If you're looking to make what you want then you're going to need to script it.  You could even get away without making any actual machinery and just create a quest that deposits items into the workshop chests, and using a holotape to turn it on or off.  The actual object doesn't do anything in itself, and it's all down to scripting or stuff the engine does itself.
