I am trying to get the number of how many empty inventory slots there are, we are talking about hotbar + regular inventory, without armor and without the second hand.

Just all of these: http://prntscr.com/jh0ucf

 

I tried using 

player.inventory.getFirstEmptyStack()

But as you can tell it will tell me if there is any space in the inventory, not how many slots there are empty.

You would need to iterate through all inventory slots and check if each one of them is empty incrementing some counter if it is.

To clarify - you would need to iterate the InventoryPlayer#mainInventory list.

Awesome, thanks.
