How do I use the /testfor command?


  • QA Engineer

    In Minecraft and in the answers I see stuff like this:

    /testfor @a[x=X,y=Y,z=-Z,r=R]
    

    Then the people say to hook it up to a /setblock command or a /fill command or etc.

    What do people mean when they say "hook up to"? How do you hook up a /testfor command block to another /setblock command? I understand the whole /testfor thing except the part on how to hook it up to another command block.



  • To use a /testfor command block, simply hook it up to your circuit with a redstone comparator.

    Arrangement of Command Block and Comparator

    When the testfor condition is met, the comparator will output a signal (out of the end facing away from the block). Simply place another command block or a redstone circuit there and it will do what you want when you want.
