Anything that can be done by a machine, without user input, should be possible. Especially if it doesn't require detection of a foreign object's state. I've been unable to do some things in my builds only because Logic is so limited. ... Or my brain is limited in creativity. Here's one example I was struggling with. Help me out. Furnace power saving: - I want to interact with a switch or a button on a wall to turn the Furnace on. - The Furnace then works for 3min and shuts down. - If the furnace is already working when I press the button, it keeps working for 3 more minutes. - If it's a switch, it flips itself off after that. If it's a button, there's also an "off" button next to it. After playing some other building games (most notably From the Depths and modded Java Minecraft), I've come to rely on automation so much that I feel crippled when I can't automate a chore.
