CHeck if node in inventory?

[azekill_DIABLO]

how to know if an item is in the inventory of the player?

EDIT:888 post!

[rubenwardy]

Use contains. http://rubenwardy.com/minetest_modding_ ... l#contains

[azekill_DIABLO]

ok thanks! i'm supposed to use

if not inv:contains_item(listname, stack) then
print("Item not in inventory!")
end

but am i supposed to replace something by the name of the item?

CAN SOMEONE HELP ME?

This is how to check for default:dirt in the player's main inventory:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

if inv:contains_item("main", ItemStack("default:dirt 99")) then
   print("Inventory contains at least 99 dirt!")
else
   print("Inventory doesn't contain 99 dirt (either less than 99, or no dirt)!")
end


You should read that chapter and the item stack chapter

ok thanks!i'm not english so i don't understand everything...sry

[azekill_DIABLO]

it says that inv is a nil value.Why?

[everamzah]

local inv = player:get_inventory() or perhaps minetest.get_inventory().

ok thx i'm dumb!

[azekill_DIABLO]

game crashes without any debug :\

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_craftitem("bandage:bandage", {
   description = "Bandage",
   inventory_image = "bandage_bandage.png",

})

local inv = minetest.get_inventory("main")

if inv:contains_item("main", ItemStack("default:dirt 99")) then
   print("Inventory contains at least 99 dirt!")
else
   print("Inventory doesn't contain 99 dirt (either less than 99, or no dirt)!")
end

minetest.register_craftitem("bandage:bandage", {
   description = "Bandage",
   inventory_image = "bandage_bandage.png",
   --i'm doing thing wrong :P
   minetest.register_on_player_hpchange(function(player, hp_change)
      function minetest.get_content_id(...)
         if hp_change>0 then
         user:set_hp(hp + 2)
         itemstack:take_item()
         end
      end
   end
)})


this is not working at all!it does not do anything!

[everamzah]

minetest.register_on_hpchange() is not an item definition, and does not belong inside of minetest.register_craftitem().

Additionally, you're checking for hp_change greater than 0, but when it's damage, it's less than zero (a negative number).

[rubenwardy]

Wow, you're doing everything wrong :P What are you even trying to do?

The following code will consume a bandage and stop a hp decrease if a bandage is in the inventory:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_craftitem("bandage:bandage", {
   description = "Bandage",
   inventory_image = "bandage_bandage.png",
})

minetest.register_on_player_hpchange(function(player, hp_change)
    if hp_change >= 0 then
        return hp_change
    end

    local inv = player:get_inventory()
    local itemstack = inv:remove_item("main", ItemStack("bandage:bandage"))
    if itemstack:get_count() == 1 then
        -- cancel hp change
        return 0
    else
        -- no bandages, don't cancel
        return hp_change
    end
end, true)

HAHA! an error!!!

Code: Select all

   local inv = player:get_inventory()
