ok so i have been toying with this idea for a while now: how to power something without actually physically touching an input.
this can be accomplished with the water glitch: if water is flowing in one direction dig a hole next to it and then when the chunk recalculates itself the water will flow in both directions. knowing this i placed a redstone torch next to the water so the torch was knocked out and the circuit powered [inverter] when the chunk recalculated. the only major drawback to this is that it can only be done once before you have to manually reset this because the torch is washed away. also you have to reset the source block of water.
the other day i [pa]trolling the redstone forums and i saw a thread someone had posted for an automatic reed farmer so i clicked it expecting nothing special but what i found was amazing. this guy had made a contraption with a source block of water and some piston and a boat with a reed next to it that worked like this.
there was a reed that wasnt fully grown, and a source block of water running into a small hole, then on the other side of the water block there was a small square with a boat on dry land and a wooden pressure plate in the corner. when the reed grew taller the chunk had to recalculate itself and therefore the the water flowed into the square with the boat. the water pushed the boat into the corner depressing the pressure plate and sending a signal through some wiring. this signal pushed a piston the chopped the top of the reed off and and also sent another signal to two piston which cut the water flow into the square[essentially resetting the water so it only flowed away from the pressure plate again, as it was originally] then as the water receded the boat moved away from the pressure plate and rested again on dry land. as the pressure plate popped back up the two piston which cut the water flow retracted but the water didn't flow back into the square until the reed grew again.
when i got home last night i tried to replicate this setup but i instead became so frustrated i eventually quit the idea.
here is where i encountered problems.
1. as i stated earlier the water should recalculate it's path when the chunk recalculates here are the things that cause a chunk to recalculate[a block being placed/destroyed, crops growing, redstone receiving a charge, or the chunk loading] but even when i dug a hole next to the source block and placed/destroyed tons of blocks i could not get the water to recalculate the flow.
2. after the water started flowing into the square and the pressure plate was depressed the signal was sent to the "cutter" piston which were supposed to stop the water flow. although they did as soon as the water flow stopped the boat simply rested on top of the pressure plate instead of moving away. i tried to fix this by using pistons to push the boat away and this just breaks it after a couple uses.
3. the piston which cut the water did not do their job correctly. the second they retracted the water would rush right back into the square again.
if anyone has built something similar or encountered similar problems help is more than appreciated, this project is HUGE and had limitless applications if i can get it to work.
thanks!
INB4 peeps ask for screenies- i will post screenies as soon as i get home but i cant post any at the moment
1) Water flows towards the nearest hole (not 100% positive on this step). If there are two nearest holes it flows according to the southwest rule (this I am positive about). As such, the water will only redirect if the hole you are sending it down is closer than the permanent hole, or you are oriented in the right direction.
2) Getting the boat to move away is tricky. You have to get the water flow direction pointed away from the plate as it drains away. Experiment with different draining set-ups and orientations.
3) The pistons have to be timed correctly, or they will cause the water block to update as they retract.
Be advised that this behavior is very glitchy and could change after any given update.

you're 100% accurate on all those facts [or atlast we both know the same thing :wink.gif:] and although that isnt the ANSWER i was looking for it does corroborate my issues...ill toy with it some more tonight and ditch it if i want get it to work.

1) Really? how come I can dig two holes three holes or even 4 holes and water will flow into every open hole. Also, water only updates when a change in a block directly adjacent above or below changes state, gets power of block gets destroyed, that's why when using the water glitch water redirection, you need to make sure there is a block below the one to the side that you are going to break, this way when it updates it will find no hole and will not flow towards the new passage. Then you destroy the next block, which seeing it's not adjacent it does not update the water and the flow stays, that's why you can do this:
and it will not update until the water or the block it's on of the block above or to a side gets power or a block to the side is destroyed or placed.
BTW, I'm not just saying this, it's also seen in the scripting of the game, if you get into modding and look at water.
