I've created a TileEntity to store the metadata of a block, when i place my block averything goes well:

 

width=800 height=419https://dl.dropboxusercontent.com/u/184200482/img/ladder_ok.png[/img]

** The blocks' metadata are the following 

| 2 | 6 | 10 | 14 | 18 | 22 |

**

 

But once I restart minecraft I see that the 

blockMetadata

information has not been stored by the TileEntity:

 

width=800 height=419https://dl.dropboxusercontent.com/u/184200482/img/ladder_bad.png[/img]

** The blocks' metadata are the following 

| 2 | 6 | 10 | 14 | 2 (18) | 6 (22) |

**

 

This is the error:

This code goes in the 

preInit

method:

Blocks.Ladder = new BlockLadder();
GameRegistry.registerBlock(Blocks.Ladder, ItemBlockLadder.class, "Ladder");

 

And this in the 

init

method:

GameRegistry.registerTileEntity(TileEntityLadder.class, "Ladder");

First of all don't just re-use Minecraft's field in the TE. It is used for something else.

You need a default constructor on your TileEntity, otherwise MC cannot load it.

 

I've been looking for where the 

blockMetadata

field were used and it's only used on the 

TileEntity.class

, so I'm assuming there is no problem if I use it to store the block metadata.

 

And looks like it works by adding the default constructor:

public TileEntityLadder() {}

 

Thanks  :)

 

PS: Unless I get an error by "re-using" Minecraft's field in the TE, I won't change it.

Search for usages on the getter (getBlockMetadata). There are a lot of usages in the minecraft codebase. Do not do this.

 

Yes, I know there are a bunch of classes using the getter, but (in my opinion) the important is to know where is the value of the field set, so as there are no setter, the only way to set the value of the field is this:

 

    public void markDirty()
    {
        if (this.worldObj != null)
        {
            this.blockMetadata = this.worldObj.getBlockMetadata(this.xCoord, this.yCoord, this.zCoord);
            this.worldObj.markTileEntityChunkModified(this.xCoord, this.yCoord, this.zCoord, this);

            if (this.getBlockType() != Blocks.air)
            {
                this.worldObj.func_147453_f(this.xCoord, this.yCoord, this.zCoord, this.getBlockType());
            }
        }
    }

 

More concretely this part:

this.blockMetadata = this.worldObj.getBlockMetadata(this.xCoord, this.yCoord, this.zCoord);

 

Which I think is the same thing that I'm doing, isn't it?
