This article assumes familiarity with the basics of redstone structures. The command block is given the command "/testfor @p[r=3]" where @p=nearest player and r=3 checks within a 3 block radius. 0. One simple way to do that is to have another row of hoppers, each with a comparator facing a command block, with redstone dust on top of the hoppers. The player is able to place redstone dust on top of the iron block and turn the dust on and off at will. It is really only effective for up to 10 outputs. Similar to the blocks that send out Redstone signals without having a Redstone component in their recipe, we also have similar blocks that get triggered by Redstone signals. Have it so the comparator strength given from a command block testing for a number is relative to the limit value given. If I understood correctly, it should be:I have even tried the (testforblock ~ ~ ~ air) command and several other blocks to see if the /testforblock command would work on anything. Run this new redstone output into command blocks THAT ARE WITHIN RANGE OF THE ENTIRE ARENA. 14 it. Note that not all "successful" commands actually do something, and not all "failed" commands fail to do. 11. Block C3 setblock pos2 redstone_block. You might be able to do this by editing the tile entity data (which is NBT data).
