[1.8] Copy Paste section of worlds

[delpi]

I have a mod that I created to do some simple world fill, delete, and copy/paste for ease of building.

 

I have a question around TileEntities, specifically chests.

 

When I copy a portion of the world with the chest, I would like the chest contents to be included.  Easy enough, grab the nbt from the tile when copying. 

 

After the paste when I write the nbt data back in, getting a world crash to the point where I can't reload the world.

 

I 'think' its because I just pasted in nbt that has position references for the tile that are wrong since it moved. 

 

Anybody got experience with doing this?  Am I going to have to carve out just the inventory part of the nbt data and deal with that?

Yes, you are right. Before reading from nbt to te, change integers in nbt: "x", "y", "z" to valid values (pos of new te).

[delpi]

Any other gotchas you can think of there?

Reset te's position right after reading from nbt.

Hi

 

One of my mods does this

There's quite a bit involved, not just NBT.  You may get useful clues from here

see WorldFragment.writeToWorldAsynchronous_do()

 

Also - 1.8. has an inbuilt command to copy a range of blocks.  Your code could just call that instead.
