I'm having the following problem, i'm trying to create a Witchery like cauldron and i need to check wether multiple Items (saved in a list) are contained in another list.

List<ItemStack> items = new ArrayList<ItemStack>();
for (int i = 0; i < tile.getInventory().getSlots(); i++){
    if (tile.getItem().getStackInSlot(i) != new ItemStack(Items.AIR)){
       items.add(tile.getItem().getStackInSlot(i));
    }
}

if (items.containsAll(recipe.catalysator)) {

    // TODO

}

The recipe.catalysator is a list that contains one item and the same item is also in the inventory.

use itemstack.isEmpty not

 != new ItemStack(Items.AIR)

@Differentiation that code block is a bit hard to read

List<ItemStack> items = new ArrayList<ItemStack>();

for (int i = 0; i < tile.getInventory().getSlots(); ++i)
{
    if (!tile.getItem().getStackInSlot(i).isEmpty())

Purge the page (reload)

So i tried this change and my inventory list doesnt contain air anymore but it still doesnt work.

can you put all your code on https://github.com/

so we can have a look
