hey guys need some help here. i was built a hidden staircase the other day and it was working great but today the 2 bottom pistons which seal off the entrance quit working...the pistons are suppose to extend and block the entrance and then retract to reveal the staircase, but for some reason they are not retracting now, this is only happening when im using a sticky piston the push and retract another piston, sticky and regular, all other blocks are extending and retract as normal! WTF...any help or ideas about a bug or anything would be greatly appreciated!! thank you all!
You have posted paths to files on your computer which others can't see (you can, because your browser can access files on your own computer, but we can't). You'll have to upload the images to a file hosting service like imgur.
If the pistons won't retract it's very likely because they're being powered from some other place than you expect. You likely have a powered block next to them or diagonally above them.
well i mean like i said its not a power problem cause theyre firing fine and was working fine but now theyre just not wanting to retract just the other pistons,,,,, and yea i F'd up trying to upload that
Did you change the thing they're pushing to a solid opaque block (like stone)? If a piston pushes a block up, and then the block gets powered in that position, the piston will get stuck activated because of quasiconnectivity.
Probably because you didn't get to the upload part?
Anyway, Munin is right, there is something powering your pistons in a BUD fashion, they are getting powered diagonally or something causing a BUD (Block Update Detector) and the reason replacing the piston works to make it retracted is because the original piston was being powered in a very glitchy fashion.
Go test this out, go power your piston so it gets stuck in the extended state, then place a block right next to the piston and see if something happens, if it does then come back and tell us, if not, come back and tell us that too.
Okay, so is the problem shown in picture 7 -- the sticky piston wall on the right didn't pull back the upwards-facing sticky piston that looks out of place? If that's the case I would guess that it was still extended when the wall tried to pull it (extended pistons can't be moved) -- you'll need to adjust the repeater timing to make sure it retracts before the wall tries to pull it back.
