I'm currently learning how TileEntities work. So I implemented McJty's great example: http://modwiki.temporal-reality.com/mw/index.php/GUI-1.9

But I noticed that items don't get dropped when the block is broken. So I tried to add that functionality by myself.

I noticed that there are 2 similar methods, harvestBlock and breakBlock. What is the difference?

 

I got it working with breakBlock. I'm not fully understanding how the new Capability system works even though I read http://mcforge.readthedocs.io/en/latest/datastorage/capabilities/

So I tried it with that, not sure if it's correct and I had to define a facing I'm accessing the item, so I defaulted to the up facing, pretty sure that's not great. Can anyone help me how to do this correct?

 

public void breakBlock( World worldIn, BlockPos pos, IBlockState state ){
        TileEntity te = worldIn.getTileEntity( pos );
        if( te instanceof TileEntityFaeryHouse ){
            ItemStackHandler ish = (ItemStackHandler)te.getCapability( CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, EnumFacing.UP );
            for( int i=0; i<ish.getSlots(); i++ ){
                if( ish.getStackInSlot( i ) != null ){
                    worldIn.spawnEntityInWorld( new EntityItem( worldIn, pos.getX(), pos.getY(), pos.getZ(), ish.getStackInSlot( i ) ) );
                }
            }
        }

        super.breakBlock(worldIn, pos, state);
    }

Ah, didn't know that I use null here, nice.

 

I get the difference between those two methods, thanks.

I'm not sure if I should open another thread rather than posting here, so I hope you don't mind if I ask another question here.

 

I now want to define if items in specific slots are extractable through hoppers/pipes.

I looked into the furnace code, it uses canExtractItem, but it doesn't use the Capability system, so I can't replicate that.

There is also canTakeStack in the SlotItemHandler, but that only defines manually extraction. If I set that to false, I can't take the item out anymore, but can still extract it with a hopper. I want the opposite though. Can someone give me a hint in the right direction?

You supply a different capability depending on the

side

parameter.

That was very helpful. Thanks.
