How to use HUD API?

[PeterKabin]

That doesn't work.

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

player:hud_add({
    hud_elem_type = "statbar",
    position = {x=0,y=1},
    size = "",
    text = "ui_heart_bg.png",
    number = 20,
    alignment = {x=0,y=1},
    offset = {x=0, y=-32},
})
health_hud[name] = player:hud_add({
    hud_elem_type = "statbar",
    position = {x=0,y=1},
    size = "",
    text = "ui_heart_fg.png",
    number = player:get_hp(),
    alignment = {x=0,y=1},
    offset = {x=0, y=-32},
})

Did anybody understood how to do it?

It added the HUD but could be invisible for you (out of the window).
Look at mods which use HUD elements and compare the codes.

Please can you explain what you want to do?

I made that mod and it does not show any text. I want to make mod, which show rules of the server.

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

tekstik="azazazaza"
while player~=nil do
    player:hud_add({
        hud_elem_type = {"text"},
        position = {x=0.5,y=0.5},
        size = {x=-20,y=-20},
        text = tekstik,
        alignment = {x=0,y=0},
        offset = {x=0,y=0},
    })
end

Getting a player object does not work like this.
Example code:

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

local initial_text = "hello world!"
minetest.register_on_joinplayer(function(player)

    local my_hud = player:hud_add({
        hud_elem_type = "text",
        position = {x=0.5,y=0.5},
        size = {x=-20,y=-20},
        text = initial_text,
        alignment = {x=0,y=0},
        offset = {x=0,y=0},
    })

end)


This adds the text as HUD of a new joined player.

Thanks.

I'm trying to make a mod, showing first white, then green text, but this mod works only sometimes:

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("testiki:tul", {
    description = "beret vesh",
    inventory_image = "testiki.png",
    on_use = function(itemstack, player, pointed_thing)
    -- Takes one item from the stack
    local tekst = itemstack:take_item()
    local hud = player:hud_add({hud_elem_type = "text",position = {x=0.3,y=0.5},direction = 0,text = tostring(tekst),scale={x=100,y=100},number = 0xFFFFFF,alignment = {x=0,y=0},offset = {x=0,y=0},})
     
    player:hud_change(hud,number,0x00FF00)
   
    return itemstack
    end,
})

How to make it always workable?

Use minetest.after to change the color after a delay.
