I have an inventory TileEntity. How do I make sure no automation mods can interact with it (like BuildCraft pipes)?

So if I don't expose it, players will still be able to interact with it? And should I implement

IItemHandler

,

IItemHandlerModifiable

and

INBTSerializable<NBTTagCompound>

?

So Minecraft itself doesn't use the methods defined by those interfaces? 

If you don't expose an IItemHandler capability on any side, there will be no automated interaction with your TE's inventory (or inventories), but players can of course still interact via any GUI you choose to attach to it via a Container.

 

What do you mean by "implement IItemHandler..." ? Your TE shouldn't be doing that at all; your TE should contain an object implementing IItemHandler (commonly just an ItemStackHandler) for each inventory it has, and, if it wants to make those available to other mods (and vanilla!), return those from getCapability(), like I do here: https://github.com/desht/ModularRouters/blob/master/src/main/java/me/desht/modularrouters/block/tile/TileEntityItemRouter.java#L156

 

(Note that vanilla items like a hopper have been retrofitted with capability awareness and will interact with any inventory you expose via capabilities).

 

You don't need to explicitly implement INBTSerializable; the TileEntity class implements that anyway, and the implementing methods just call readFromNBT() and writeToNBT(), which are the methods you should normally be overriding.

I talked about implementing those interfaces because my

TileEntity

is a chest

"is a chest"?  You mean, you're directly extending TileEntityChest, or you're creating a tile entity with chest-like functionality?

 

Have you looked at the code for TileEntityChest (note, it gets tricky because of double chests).  You'll see that even vanilla chests implement getCapability() & hasCapability() for ITEM_HANDLER_CAPABILITY.

 

But I think the short answer to your question is no: you don't need to implement any of those interfaces.

public class Tilelol extends TileEntity {

    ItemStackHandler itemStackHandler = new ItemStackHandler(5);

 

    @Override

    public void readFromNBT(NBTTagCompound compound) {

        itemStackHandler.deserializeNBT(compound.getCompoundTag("llo"));

        super.readFromNBT(compound);

    }

 

    @Override

    public NBTTagCompound writeToNBT(NBTTagCompound compound) {

        super.writeToNBT(compound);

        compound.setTag("llo", itemStackHandler.serializeNBT());

        return compound;

       

    }

}

is this what you want ?
