i am trying since 24 hours without sleep to figuring out how redstones work etc. And i learned alot in creative mode from redstones.
I built successfully a piston door which works with a lever and redstones.
I have a small problem: When i turn on the lever, the piston door opens successfully. I want now another lever for the other side of the room which i can only access currently from the one side where i have the first lever, if you know what i mean XD.
I want to use 2 levers for the same piston. How gonna i do it for a 2x2 room ?
Edit: Alright i made some tests and i can't figure out how to get 2 levers for one "conection" work don't matter if the first lever is ON or OFF.
Watch this screen and look on the right lever. The left lever is on ON, and because of that, the lever on the right does nothing.
What i wan't is, that IF Lever A is ON, that lever B turns A off on the next push / right click. And IF A is OFF, i want that B turns it ON on a right click .... so hard ? xD
Took me 30+ hours non stop playing without sleep, i was keep trying till i figure it out by my own and now it works like a charm.
Check my image, that's how i solved the problem. It doesn't matters anymore that Lever A is on ON or OFF. I can still turn ON and OFF lever B whenever i wan't :).
When i open (turn on) the door with lever A and keep it open, and press Lever B, the door closes (and if i right click again on lever B or even A, the door opens). When i close (turn off) the door with lever A and keep it closed, and right click on lever B (or lever A) the door opens.
