Finding the amount of items in a stack(SOLVED)
Posted: Tue Dec 31, 2013 23:05In Minearriatest's Jungletools mod, there is a grinder node. This grinder's formspec has 2 slots (input, output) and a button (Grind). However, on clicking Grind, only one item is removed from the input slot, and only 1 is added to the output. Is there a way to find the amount of jungletools:jungle_spore craftitems in the input slot and add that many jungletools:jungle_dust to the output slot on_recieve_fields?
