I set a command block to /tp. It was supposed to activate only if you had 0 time left, and to activate the command block with a hopper clock to keep giving it power.

But it is not checking if you have 0 time left, so it keeps teleporting me. I can't get close enough to the command block to break it, so I'm stuck in a neverending teleport loop.

Any ideas?

If you are running this world on a multiplayer server, you can disable command blocks completely via the server properties. Shut down the server, open server.properties with a text editor of your choice and set

enable-command-block = false

This disables all command blocks. Join the game, destroy the command block in question and reenable them afterwards.

In singleplayer, it's a bit more complicated. You have to open the world as a multiplayer* server. Open server.properties and set

level-name = [relative path to your savegame]

e.g. saves/world (use / to divide folders).

*If you haven't run a multiplayer server yet, you can download the server.jar (or server.exe) from the Minecraft website and save it wherever you want. Run it once to generate some files, including server.properties and a savegame called world.

To join your own server, connect to localhost or in Minecraft.

I think that this solution works best if you're already running a server. –  Riking Jun 2 '14 at 9:14

For situations like this, an external world-editing tool is best. Find the command block, and delete it.

A common one is MCEdit, which is available here: http://www.mcedit.net/

As @MrLemon mentions, you could be running a multiplayer server, in which case MCEdit is a bad idea -- the download time of a 60GB map is non-negligible. In that case, follow his answer.

If the command block is not at the spawn; tpye /kill. But if one is at spawn just look down real quick and break it if you can.

destroy the block using a world editor, then use a command block to comparator for the test part with the /testfor command, you want the comparator to go to a command block that just puts up a message to start with to find out if the /testfor command and comparator are working properly, do not start the /tp command until you have confirmed that the first two parts are working in conjunction with each other propperly

Heres what I did. Watch this video and you can watch me solve the problem as I was dealing with it.

Please summarize the method used in the video to solve the problem of this question. Answers should be able to stand on their own; if the video were to go down for some reason, your answer as it stands would not help anyone. –  Trent Hawkins Dec 29 '14 at 5:08
