Hello Everyone,

I am trying to create a sign with the following code, but for some reason it doesn't work. Do you know why?

Code: Select all

minetest.register_node(
   'tutorial:sign',
   {
     description='sign',
     drawtype='nodebox',
     tiles={'tutorial_sign_wall.png'},
     inventory_image='tutorial_sign.png',
     wield_image='tutorial_sign.png',
     groups={dig_immediate=2},
     paramtype2='wallmounted',
     selection_box={
       type='wallmounted',
       wall_top={-0.4375, 0.4375, -0.3125, 0.4375, 0.5, 0.3125},
       wall_bottom={-0.4375, -0.5, -0.3125, 0.4375, -0.4375, 0.3125},
       wall_side={-0.5, -0.3125, -0.4375, -0.4375, 0.3125, 0.4375}
     },
     walkable=false
   }
)

It looks like this:

I have another problem. This time I try to create a liquid, but I get error messages that I don't understand. The error message is: "ERROR[Server]: Map::setNode(): Not allowing to place CONTENT_IGNORE while trying to replace "air" at (-2,9,-33) (block (-1,0,-3))". Do you know how to fix it?

[rubenwardy]

you wrote liquid_alternativ_source in the first def

[Gibeinumo]

I also wrote alterntative. That was the problem, thanks :)

You're not the first person who has problems understanding the misleading CONTENT_IGNORE error message.

I encountered another problem with the following code.

Code: Select all

minetest.register_node(
  'vsb:test',
  {
    description='test',
    tiles={
      'default_dirt.png',
    },
    groups={crumbly=3},
    on_use=function(itemstack,player,pointed_thing)
      minetest.chat_send_all(itemstack:get_count())
      itemstack:take_item(1)
      minetest.chat_send_all(itemstack:get_count())
      player:set_breath(5)
      player:set_wielded_item(itemstack)
    end
  }
)

The amount of items is reduced by one and the breath is set to five, but for some reason the amount of wielded items doesn't change. In theory it should work even without calling set_wielded_item. Do you know how to fix it?

[Linuxdirk]

You need to return the modified itemstack.

[Gibeinumo]

Ah, thx. I changed the itemstack and then it was changed again by the function. :)
