In the new update for Minecraft pocket edition, it said that it added command blocks. What command do you use to get it?
I have tried every command I can think of, but they won't work. Is there a command I should use to get access to all other commands?
You should be able to use any command available on the pocket edition. I found a list of commands here.
Remember that command blocks need to be powered with Redstone before their command will activate, and that the command itself must be syntactically correct.
