[SOLVED] [1.10.2] How to set inventory stack limit with capabilities

[Daeruin]

I am trying to update my custom containers to the capability system. My old tile entity class implemented IInventory and made use of the very handy built-in getInventoryStackLimit method to limit the number of items allowed in each slot. Now I'm using ItemStackHandler, and I'm left wondering how to set a stack limit on my container. I didn't see a similar method in ItemStackHandler except getStackLimit, but that refers to a property of the ItemStack rather than the container.

 

Thanks in advance for any tips you have on how to achieve this.

That is the right method to override to change the stack limit.

OK... so to do that, do I need to replace ItemStackHandler with my own class that implements IItemHandler?

Or extend ItemStackHandler, or create an anonymous class of ItemStackHandler that overrides getStackLimit.

you need to update to 1.11.2 to have ( int getSlotLimit(int slot); )

That's good to know. I'm still trying to update to 1.10.2 from 1.8.9, and it's taken me several months. So I'm reluctant to try to update further at the moment.

I had never heard of anonymous classes before, so I read up on them and realized I had seen them before without knowing what to call them. So I experimented a little and came up with something that seems to work.

 

public class PrimalTileEntity2 extends TileEntity {

private ItemStackHandler inventory;
private int numSlots;

public PrimalTileEntity2(int numSlots, final int stackLimit)
{
this.numSlots = numSlots;
inventory = new ItemStackHandler(this.numSlots)
{
	@Override
	protected int getStackLimit(int slot, ItemStack stack)
	{
		return Math.min(stackLimit, stack.getMaxStackSize());
	}
};
}
