[1.12.2] Strong redstone power instead of weak? in Modder Support Posted January 5, 2018 · Edited January 5, 2018 by IceMetalPunk Okay, so after a lot of debugging, I finally got it working. I took some inspiration from how the observer block works and manually called World#notifyNeighborsOfStateChange, on all adjacent blocks, after setting the powered or unpowered block states of the Gazing Glass. It now works just fine I was under the impression that such block updates occurred automatically when you set a block state, but apparently not. Is there a better way to do this, or is that the correct way?
