I have a custom block which has a facing direction and a type. A facing direction already uses up most of the metadata that a block can store, and I need to have at least more than 8 variants of a block along with its facing direction. How can I render by both its facing direction and its type without passing the metadata limit, or get more metadata I can have on my block?

 

This block does have a tileentity associated with it, so if there is any way to move the block rotation rendering into the tileentity, that would work fine

 

    public static final PropertyDirection FACING = PropertyDirection.create("facing");
    public static final PropertyInteger TYPE = PropertyInteger.create("type", 0, 31);

    @Override
    public int getMetaFromState(IBlockState state) {
        int i = 0;
        i = i | ((EnumFacing)state.getValue(FACING)).getIndex();

        {
            i |= 8;
        }
        
        i = i | ((Integer)state.getValue(TYPE)) << 3;

        return i;
    }

Metadata is limited to 16 values, so a property with 6 values limits you to one other property with 2 values (2 * 6 = 12, 3 * 6 = 18).

 

If you require additional values, you need to store them in a

TileEntity

. If you want to use them to determine the model, override

Block#getActualState

to set the property from the value stored in the

TileEntity

.

 

You can see an example of this here:

TileEntity

The blocks I need this for are already tileentitites

 

How can I then render them facing their direction with submodels for the different types?

 

Or does the getActualState allow more than the 15 bits

 

Edit: I'm stupid

Also, don't create your own PropertyDirection, use the one from BlockDirectional

Also, don't create your own PropertyDirection, use the one from BlockDirectional

And make a conscious decision on whether you want to use UP and DOWN (like a piston) or  only N, S, E & W (like a furnace). If the latter, use BlockHorizontal.

 

Actual state receives a state (probably made from a metadata value 0-15) and returns another block state, not and integer, so it is not limited. You just need to set each property within the range for that property. The method may reach out to the world (neighbor blocks, tile entities etc) to get data for deciding the actual state.
