[1.12] Hopper and custom container.

Recommended Posts

Hi, 

 

I created a new chest, but after many times I saw that it was possible with a hopper to extract item from my custom chest. But I didn't add anything and I wanted to know if there is a simple way to disable it ? I've searched and I saw IItemHandler but It didn't work. I added it in my tile entity and tried but without success :/ This is my tile entity :

public class TileEntityBlockVault extends TileEntity
{
	ItemStackHandler inventory = new ItemStackHandler(27);
	public String ownerS = "";
	
	public TileEntityBlockVault()
	{
	}
	
	
	
	public TileEntityBlockVault(String ownerData)
	{
		 this.ownerS = ownerData;
	}
	
	
	
    public void setString(String string)
    {
        this.ownerS = string;
    }
    
    
    
    @Nullable
    public String getOwnerS()
    {
        return this.ownerS;
    }
	
	@Override
	public NBTTagCompound writeToNBT(NBTTagCompound compound) 
	{
		compound.setTag("inventory", inventory.serializeNBT());
		compound.setString("ownerS", this.ownerS);
		return super.writeToNBT(compound);
	}
	
	
	@Override
	public void readFromNBT(NBTTagCompound compound) 
	{
		super.readFromNBT(compound);
		inventory.deserializeNBT(compound.getCompoundTag("inventory"));
		this.ownerS = compound.getString("ownerS");
	}
	
	 
	@Override
	public boolean hasCapability(Capability<?> capability,@Nullable EnumFacing facing) 
	{
		return capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY || super.hasCapability(capability, facing);
	}
	
	@Override
	public <T> T getCapability(Capability<T> capability, @Nullable EnumFacing facing) {
		return capability == CapabilityItemHandler.ITEM_HANDLER_CAPABILITY ? (T)inventory : super.getCapability(capability, facing);
	}


}

 

How can I do that ? Thank you :)

You are gonna want to check the facing value in hasCapability and getCapability and if it is anything, but null say you don't have it or it doesn't exist.

VANILLA MINECRAFT CLASSES ARE THE BEST RESOURCES WHEN MODDING

I will be posting 1.15.2 modding tutorials on this channel. If you want to be notified of it do the normal YouTube stuff like subscribing, ect.

Forge and vanilla BlockState generator.

Ok, yep I removed the capabilities and I've done that instead in my other class ! It works but is that correct ?

 

I added in tile entity

 

	public ItemStackHandler getHandler()
	{
		return inventory_seller;
		
	}

 

And then I've done that in container/guis

 

IItemHandler inventory = te.getHandler();

 

It works perfectly fine ^^
