I’ve been looking for instructions and haven’t found a conclusive tutorial on this, so here is a quickie:
POWER – GENERATORS Build a generator.
POWER – CONNECTORS&SWITCHES Build power pylon.
Connect generator to pylon with wire (option is shown while looking at the object in workbench mode, PC shortcut “space”)
POWER – CONNECTORS&SWITCHES Place a switch near where you want your light to be.
Connect switch to pylon with wire (see above).
POWER – LIGHTS Place a light bulb in the vicinity of your switch.
If the switch is in range of your light, it doesn’t need any further connecting, the light bulb will just be powered. It confused the heck out of me, but that’s how it is. Kind of electricity wifi. Oh joy, the future?
Flip switch like an idiot and be happy: you just made light!
