Need help on groups

[LvCoetzer]

Hello there guys, I've started developing a mod which will add quantum mechanics to the game, but I am struggling to get the sub groups to work and to let the actual group appear in the crafting area. My item-groups.lua is as follows:

Code: Select all

data:extend({
--Main item group
	{
    type = "item-group",
    name = "quantum-stuff",
	icon = "__Quantum_Stuff__/graphics/group_icon.png",
    order = "f",
	inventory_order = "f"
	
  },
-- Crafting materials subgroup
  {
	type = "item-subgroup",
	name = "material",
	group = "quantum-stuff",
	order = "a"
  },
-- Entity subgroup
  {
	type = "item-subgroup",
	name = "gate",
	group = "quantum-stuff",
	order = "b"
  }
})

When I try to launch the game, it tells me that the sub groups don't exist. What am I doing wrong?
Here is the item.lua:

Code: Select all

data:extend({
	{
		type = "item",
		name = "quantum-chip",
		icon = "__Quantum_Stuff__/graphics/icons/quantum-chip.png",
		flags = {"goes-to-main-inventory"},
		--subgroup = "material",
		order = "a[quantum-chip]",
		stack_size = 50
	},
	{
		type = "item",
		name = "quantum-gate",
		icon = "__Quantum_Stuff__/graphics/icons/quantum-gate.png",
		flags = {"goes-to-quickbar"},
		--subgroup = "gate",
		order = "b[quantum-gate]",
		--place_result = "quantum-gate",
		stack_size = 2
	}
})
