Hi,

I'm initialising my TileEntity in the Constructor of it, but at the point when i want to open my GUI the data is null.

 

My code is here: https://github.com/siiikooo0743/Extradimensional-Hotbar

what exactly is null ? because there nothing initialized in the tile entity related to NBT and the gui doesnt ask for anything either (anything related to NBT )

First, don't use this:

Minecraft.getMinecraft().theWorld.markBlockForUpdate(this.xCoord, this.yCoord, this.zCoord);

You set your world object for the tile entity and then don't use it? Using that could be bad. Aside from that tidbit (and the way you did your NBT, that was just strange), what hydroflame said.

@Guff

I set the worldObj. because otherwise this happens:

EDIT: I removed the

Minecraft.getMinecraft().theWorld.markBlockForUpdate(this.xCoord, this.yCoord, this.zCoord);

@ hydroflame

 

The Array "content" is null and the int sze is 0.

because there nothing initialized in the tile entity related to NBT and the gui doesnt ask for anything either (anything related to NBT )

What do I need to do?

I did it like in the tutorial: http://www.minecraftforge.net/wiki/Basic_Tile_Entity

 

Thanks for answering btw

Why can't I?

I just pass the World- Parameter of the

createNewTileEntity

as an parameter to my TE.

That seemed to work fine.
