[1.11.2] A problem with Item handler capability

[tommyte]

Hello everyone,

 

I'm working on a multiblock structure with a core tile entity that should store all the data, like items. I got another tile entity in the multiblock that should be able to in- and output items to and from the inventory of that core tile entity. I tried to achieve this by returning the instance of the ItemStackHandler of the core tile entity in the getCapability method in the other tile entity. It looks like this:

//The class that should in and output to the core tile entity
public class TileEntityMultiblockItemHandler extends TileEntity implements IMultiblockTileEntity{

	private TSMultiblock block;
	
	public TileEntityMultiblockItemHandler()
	{
		
	}
	
	@Override
	public TSMultiblock getMultiblock() 
	{
		return ((IMultiblockBlock)world.getBlockState(pos).getBlock()).getMultiblock(world, pos);
	}
	
	@Override
	public boolean hasCapability(Capability<?> capability, EnumFacing facing) 
	{
		if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) 
		{
			return true;
		}
		return super.hasCapability(capability, facing);
	}
	
	@Override
	public <T> T getCapability(Capability<T> capability, EnumFacing facing) 
	{
		if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) 
		{
			return (T) getMultiblock().getCoreEntity().getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, facing);
		}
		return super.getCapability(capability, facing);
	}

	@Override
	public void onMultiblockLoad() 
	{
		
	}
}

 

And

 

//The core tile entity
public class TileEntityFabricator extends TileEntityMachineBasic implements ITickable, IInteractionObject, ITileEntityInterface{

	private int currentFormTime;
	private int totalFormTime;
	private int energyConsumption;
	private TSEnergyStorage energy;
	private TSItemStorage inventory;
	
	public TileEntityFabricator()
	{
		totalFormTime = TSConfigHandler.runtimeFabricator;
		currentFormTime = 0;
		energyConsumption = TSConfigHandler.fabricatorConsumption;
		energy = new TSEnergyStorage(10000, 0, 0);
		inventory = new TSItemStorage(10);
	}
	
	//I left a bunch of methods out here
	
	@Override
	public boolean hasCapability(Capability<?> capability, EnumFacing facing) 
	{
		if (capability == CapabilityEnergy.ENERGY) 
		{
			return true;
		}
		if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) 
		{
			return true;
		}
		return super.hasCapability(capability, facing);
	}
	
	@Override
	public <T> T getCapability(Capability<T> capability, EnumFacing facing) 
	{
		if (capability == CapabilityEnergy.ENERGY) 
		{
			return (T) energy;
		}
		if (capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY) 
		{
			return (T) inventory;
		}
		return super.getCapability(capability, facing);
	}
}

 

The problem: when I attach a hopper to the itemhandler tile entity, it inputs items, but I can't see them on the gui. Furthermore, I can get the items I put in out again with a hopper, but the items inside that I can see and access through the gui stay put. What have I done wrong?

quick spelling corrections (:

False alarm, I figured it out already. My 'getCoreEntity()' method didn't work properly. I wonder why it didn't spit out an error, but o well. Thanks anyways!
