i found out how to do it, but can i ask another question?
How do i get more than 15 blocks powered so that i can sense a mob from the bottom of the thing?
That is quite simple :smile.gif:
Just add 2 blocks with torches on the redstone path
Edit: Ah ninjad, though I never thought of that, much more compact version, I will leave my version though, as you can have 15 blocks of red powder between each
Just as long as you have an even amount of them, they essentially flip the signal, so 1 of them will reverse the signal, another will reverse it back, but by simply having 15 redstone between each one, in the example I gave, you can have 15 between the pressurepad and the first, between the 2, and at the end, which gives you 49 blocks inbetween.....
Of course, doesn't matter if you're within 30 blocks of the pads you want to connect(and you can just use what sonic posted), just thought I would explain it
