SOLVED: How to Check for Item in Another Mod?

[Grizzly Adam]

I want to check and see if crops:peppercorn is present, and if so run the below script. Otherwise I want to end.

I just can't quite figure out how to write it and google is failing me.

Code: Select all

--if crops.peppercorn isn't present, then end

	on_place = function(itemstack, placer, pointed_thing)
		local under = minetest.get_node(pointed_thing.under)
		if minetest.get_item_group(under.name, "soil") <= 1 then
			return
		end
		crops.plant(pointed_thing.above, {name="crops:pepper_plant_1", param2 = 1})
		if not minetest.setting_getbool("creative_mode") then
			itemstack:take_item()
		end
		return itemstack
	end
})

First, make sure your mod lists crops as a dependency.
Then check minetest.registered_items["crops:peppercorn"] to see if it is nil or not.

I might add that you should only need to 'soft' depend on the crops mod to ensure it gets loaded before yours.

Also, if you are going to check this repeatedly it would be worth storing the result in a local variable, eg.

Code: Select all

local has_peppercorn = minetest.registered_items["crops:peppercorn"] ~= nil

Again, thank you. It worked very well.
