Wie fügt man in einer Mod einen neuen Block hinzu der was bestimmtes craften kann

by debiankaios » Post

Hallo, ich arbeite gerade an der 1.0 von alien_material. Dort kommt eine neue Alien Bench hinzu! Ich habe den OFen kopiert aber das funktioniert noch nicht so gut:

Code: Select all

-- default/furnace.lua

-- support for MT game translation.
local S = default.get_translator

--
-- Formspecs
--

function default.get_furnace_active_formspec(fuel_percent, item_percent)
	return "size[8,8.5]"..
		"list[context;src;2.75,0.5;1,1;]"..
		"list[context;fuel;2.75,2.5;1,1;]"..
		"image[2.75,1.5;1,1;default_furnace_fire_bg.png^[lowpart:"..
		(fuel_percent)..":default_furnace_fire_fg.png]"..
		"image[3.75,1.5;1,1;gui_furnace_arrow_bg.png^[lowpart:"..
		(item_percent)..":gui_furnace_arrow_fg.png^[transformR270]"..
		"list[context;dst;4.75,0.96;2,2;]"..
		"list[current_player;main;0,4.25;8,1;]"..
		"list[current_player;main;0,5.5;8,3;8]"..
		"listring[context;dst]"..
		"listring[current_player;main]"..
		"listring[context;src]"..
		"listring[current_player;main]"..
		"listring[context;fuel]"..
		"listring[current_player;main]"..
		default.get_hotbar_bg(0, 4.25)
end

function default.get_furnace_inactive_formspec()
	return "size[8,8.5]"..
		"list[context;src;2.75,0.5;1,1;]"..
		"list[context;fuel;2.75,2.5;1,1;]"..
		"image[2.75,1.5;1,1;default_furnace_fire_bg.png]"..
		"image[3.75,1.5;1,1;gui_furnace_arrow_bg.png^[transformR270]"..
		"list[context;dst;4.75,0.96;2,2;]"..
		"list[current_player;main;0,4.25;8,1;]"..
		"list[current_player;main;0,5.5;8,3;8]"..
		"listring[context;dst]"..
		"listring[current_player;main]"..

		"listring[current_player;main]"..
		"listring[context;fuel]"..
		"listring[current_player;main]"..
		default.get_hotbar_bg(0, 4.25)
end

Starting with modding in Minetest I would recommend this:

Try downloading other mods and see how things work.

Hm... technic has some sort of custom crafting system, afaik they also allow to "register" new machine types but i don't know how flexible this is.

Otherwise you are probably better off using one of the alternative crafting systems, like this:
