Hello all,

 

So I have this directional block in my mod, that accepts 3 types of capabilities (fluids, energy and items), however, on the front of the 'machine' I want the capabilities to return null, so it does not connect to any power handlers / fluid handlers / item handlers. I have most of it working, other than finding the side for it to return null on. I have tried this:

    	IBlockState state = this.world.getBlockState(this.getPos());
    	EnumFacing front = EnumFacing.getFront(state.getBlock().getMetaFromState(state));
    	if(facing != front) {
    		return this.storage;
    	}
		return null;

however, only 1 direction (north) actually returns null on the front.

 

How can I find the front of a directional block?

 

Thanks.

.getMetaFromState(state)

No. Bad modder.

EnumFacing facing = state.getValue(BlockDirectional.FACING)

I changed my code:

    @Override
    public IEnergyStorage getEnergyStorage(EnumFacing facing) {
    	IBlockState state = this.world.getBlockState(this.getPos());
    	EnumFacing face = state.getValue(BlockDirectional.FACING);
    	if(facing != face) {
    		return this.storage;
    	}
		return null;
    }
    
    @Override
    public IFluidHandler getFluidHandler(EnumFacing facing) {
    	IBlockState state = this.world.getBlockState(this.getPos());
    	EnumFacing face = state.getValue(BlockDirectional.FACING);
    	if(facing != face) {
    		return this.fluidStorage;
    	}
		return null;
	}
    
    @Override
    public IItemHandler getItemHandler(EnumFacing facing) {
    	IBlockState state = this.world.getBlockState(this.getPos());
    	EnumFacing face = state.getValue(BlockDirectional.FACING);
    	if(facing != face) {
    		return this.slots;
    	}
		return null;
    }

However now it crashes:

java.lang.IllegalArgumentException: Cannot get property PropertyDirection{name=facing, clazz=class net.minecraft.util.EnumFacing, values=[down, up, north, south, west, east]} as it does not exist in BlockStateContainer{block=ce:void_infuser, properties=[facing]}

Ah, you're using the horizontal facing.

s/BlockDirectional.FACING/FACING

 

Also:

public static final PropertyDirection FACING = PropertyDirection.create("facing", EnumFacing.Plane.HORIZONTAL);

You can just use BlockHorizontal.FACING, rather than creating a new property.

Okay I changed to use the property from BlockHorizontal, but I didn't understand what you meant by:

As I still don't see the problem on why its crashing.

 

Okay, I picked up on what you meant, I changed your code to this:

    	EnumFacing face = state.getValue(BlockHorizontal.FACING);

However, the back of the machine is being ignored, not the front

Edited March 29, 20187 yr by Lambda

Maybe I should do a bit of looking around before asking for more help.

EnumFacing.getOpposite() seems to work great for this.

 

Thanks for your help!
