Greetings! It's been a while since I've asked a question here.

 

I was wondering if it's necessary to save the metadata in the NBT data of the TileEntity of a block.

 

BlockFurnace does not do that, yet it managas to save the direction it's facing.

 

I took a look at the Transposer from Redpower, it uses NBT. (link to redpower TileMachine)

 

This is my current code:

 

 

 

public class BlockItemRelay extends BlockSingularityBlock{

 

public static final String NAME = "ItemRelay";

 

private IIcon topIcon,bottomIcon,sideIcon;

 

public BlockItemRelay() {

super();

setBlockName(NAME);

setBlockTextureName(Singularity.MODID + ":" + NAME);

}

 

@Override

public TileEntity createNewTileEntity(World world, int meta) {

return new TileEntityItemRelay();

}

 

@Override

public void registerBlockIcons(IIconRegister register) {

topIcon=register.registerIcon(getTextureName()+"_top");

bottomIcon=register.registerIcon(getTextureName()+"_bottom");

sideIcon=register.registerIcon(getTextureName()+"_side");

}

 

@Override

        public IIcon getIcon(int side, int meta){

                if(meta==side) return bottomIcon;

                if(meta/2==side/2) return topIcon;

                return sideIcon;

        }

 

@Override

public void onBlockPlacedBy(World world, int x,int y, int z, EntityLivingBase entity,ItemStack stack){

super.onBlockPlacedBy(world,x,y,z,entity,stack);

world.setBlockMetadataWithNotify(x,y,z,Utils.getMetaFromDirection(entity.rotationYaw,entity.rotationPitch),1);

}

}

 

 

 

The metadata returned from Utils.getMetaFromDirection(yaw,pitch) is correct, and I added a line to the TileEntity of this block that prints the metadata of the block. It has the correct value.

 

Now, when I exit the world and enter again, it prints -1. What. Am I really supposed to use NBT data here? I thought metadata was something saved automatically?

 

Thanks in advance,

Pancake

Yes, metadata is saved automatically. But what Eloraam has done there is not metadata, but rather just a simple field in TileMachine that has to be saved to NBT. The vanilla furnace does use metadata to store it's rotation.

I just figured it out!

 

I was using the TileEntity's blockMetadata. It said -1, but worldObj.getBlockMetadata(xCoord,yCoord,zCoord) gave me the correct metadata.

 

I know I have to use the getBlockMetadata method now, which initialises the blockMetadata if it's -1. My bad! :3

 

It's weird that that field isn't initialised from the start though.
