[1.12.2] Specify which Container Slot a hopper can take


MisterGamer _

Recommended Posts

I have a Container with 2 slots; one for input and one for output.

 

The Output Slot is a custom-made Slot and here is it's code:

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.ItemStack;
import net.minecraftforge.items.IItemHandler;
import net.minecraftforge.items.SlotItemHandler;

public class CompactorOutputSlot extends SlotItemHandler{

	private int removeCount;
	
	public CompactorOutputSlot(IItemHandler itemHandler, int index, int xPosition, int yPosition) {
		super(itemHandler, index, xPosition, yPosition);
	}

	@Override
	public ItemStack onTake(EntityPlayer thePlayer, ItemStack stack) {
		this.onCrafting(stack);
		super.onTake(thePlayer, stack);
		return stack;
	}

	@Override
	public boolean isItemValid(ItemStack stack) {
		return false;
	}

	@Override
	public ItemStack decrStackSize(int amount) {
		if(this.getHasStack()) this.removeCount += Math.min(amount, this.getStack().getCount());
		return super.decrStackSize(amount);
	}
	
}

 

How can I specify which of the two slots the hopper can take?

You do it by exposing the TileEntity's item stack handler capability by side. If the hopper can only take the output slot, then you only let it access the output slot when the side being accessed is DOWN.

Vice versa for the input slot.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Is it the same on a block without the facing property?

That is a block without a facing parameter. If you mean one that has a facing property:
