Hi, is there any plugin wrapper or Bukkit Mod that adds in the command onBlockPower or onBlockPowerChange? So far I looked into the listeners and the only way I could think of doing anything like this is to search the redstone wiring that has changed state with onRedStoneChange() and scan its proximity for powered or unpowered block. However this becomes quickly inefficient and doesn't allow for blocks directly powered by lever or button. So is there?
