So, I have a TileEntity that extends IInventory. I now want to make it so players can only take items out of the inventory and never put them in. How would I go about that?

You would need to create a custom Slot class that returns false for isValid.  The TE would be able to move inventory items around all it wants, as the isValid check only applies to players (there's another, separate function for sided inventories for things like pipes).

 

Check the GUI for the furnace.  The slot on the right is the kind you're looking at.

Okay, thanks!

Is there an easier way to add your own slots than replacing each slot in EntityPlayer.openContainer? It just seems a bit messy.

How do you mean? You're just replacing the creation of normal Slots by your own slot in your Container class, right? That isn't messy.. Or can you show some code  what you think is messy?

I don't have a container class. Just a TileEntity that implements IInventory.I just call displayGUIChest whenever someone right clicks the containing block.

You should create your own GUI container classes.

They aren't that difficult.  Annoying, time consuming, and taking a ton of classes.

 

But not difficult.

If I can ever get around by NOT making a custom GUIcontainer I will, like when I created a different kind of dispenser (it had different behaviors but was for all intents and purposes still a dispenser) I just extended TileEntityDispenser and used the Dispenser GUI.

Okay, thanks for the help. I'll give it a shot.
