Looking for a point in the right direction.

[droon456]

I am in the process of learning lua so I have been setting myself some small feature goals.

My goal today is to make a small power system that includes a generator entity that can be connected with a stool to something like a money printer.

I would like to have a limit of 5 printers per power point and have them be able to be removed and for them to act correctly if the power source is removed/destroyed.

I haven't done any work with connecting entities before and would like to be pointed in the right direction.
