Is there a cap on how many slots a container can hold? The code should be adding about 62 slots, but the slots list has a size of 45 when it's done adding the slots.

 

The weird part is that all of the slots are rendered, but if I try to click on one of the slots that are added after the first 45 are added, I crash with an NPE stating that the index is out of bounds.

 

Container Class:

package ttm.inventory;

import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.Container;
import net.minecraft.inventory.IInventory;
import net.minecraft.inventory.Slot;
import ttm.util.LogUtil;

public class ContainerInventory extends Container {
public IInventory inventory;

public ContainerInventory() {
	super();
	inventory = new InventoryT();
	int currentSlot = 0;
	for(int i = 0; i < 9; i++) {
		this.addSlotToContainer(new Slot(inventory, currentSlot, 10 + (18 * i), 14));
		currentSlot++;
	}
	for(int i = 0; i < 9; i++) {
		for(int l = 0; l < 6; l++) {
			this.addSlotToContainer(new Slot(inventory, currentSlot, 10 + (18 * i), 52 + (18 * l)));
			currentSlot++;
		}
	}
}

@Override
public boolean canInteractWith(EntityPlayer var1) {
	return true;
}
}

Huhh? NPE != OOBE

 

Yeah, the index is out of bounds so the list returns a null.

 

(I think)

 

 

Here's the crash log if you need it:
