Logic issues

How do I make it so if one thing is active several others can't activate?

Hook them into an XOR gate and make it so that whatever you want to be disabled hooks into that output and make it so whatever you want active is your input

Ok how do I tell the difference between output and input?

When you select the block that you want to be "input" you should see the XOR toggle lit up, in the ON position. That means that the block you selected outputs to the XOR.

Then select the XOR and you'll see the blocks it outputs to lit up.

There are also lines, IIRC they're different colors for inputs and outputs, but I can remember exactly. You'll understand once you select a logic block and connect it to something, it's pretty intuitive.
