Unable to locate house in Minecraft PE

My son has spent a long time making a big house in creative mode of Minecraft and now someone else has played in that world and he can't navigate back to his house. Can anyone help?

Solution 1:

There are 2 ways to do relocate your build:

1. Let's say that your build was not too far from spawn, and the person that went on this map flew you far away, then it would just be a simple /tp @p 0 100 0 command that you could execute. This method could also work if you remember around where the build was, let's say it was around 300 blocks from spawn, execute /tp @p 0 100 0 then face the direction of your build and do /tp @p ~ ~ 100 (This may not work for PE)
2. If your build was in a completely random location, you will need to follow this method:
   1. On your computer, download a software that can view the files of your iPad, I recommend iExplorer
   2. Download MCedit
   3. Navigate to your "saves" folder as follows: Apps -> com.mojang.minecraftpe -> Documents -> games -> com.mojang -> minecraftWorlds -> <worldname> Substituting <worldname> for the name of your world.
   4. Copy level.dat in a folder that you can access on your computer (such as desktop)
   5. Run MCedit using the level.dat that you just copied.
   6. Locate your world there: You can use the block search function to look for specific builds, or search for "non-natural blocks" Refer to this on how to find you build on MCedit.
   7. Copy down the coordinates, and paste that into you tp command like this /tp @p X Y Z Substituting X Y Z for the appropriate number.
