what you do is drag the blocks so that they connect and make a circut to change the direction of a block, you put your mouse over it and press the arrow key facing the direction you want. to delete a block, put your mouse over it and press d. NOT blocks change the signal from on to off or vice versa. AND blocks need to receive ON signals on both receiving things OR blocks need to receive ON signals on only one of the receiving things XOR blocks need to receive OFF signals on one of the receiving things the power blocks are power scource the wires are for long distance connections. you put the green dot on the signal you want to transmit, and put the other dot(the one its connected to) on the place you want to transmit it to.
please use my copying script in other projects i couldn't find a way to duplicate the long distance connectors UPDATE: spliters they turn 1 connection into two!
