I know how to install mods per game and also globally. Is there a way to install mods per world?

I know how to install mods per game and also globally. Is there a way to install mods per world?

In world folder u must make new folder named "Worldmods" and here u can give mods which u want to have in gameplay

[hunterdelyx1]

Why is nobody reading https://github.com/minetest/minetest/bl ... ua_api.txt?

>/worlds/*WORLDNAME*/worldmods
Both mods in this folder and global mods will work.

>/worlds/*WORLDNAME*/game/mods
Creating special game for this world. Only mods from this folder will work.

is there any code behind the air nodes?/any way to write a pseudo-air node?

Spoiler

a node that mimics air so closely that an abm could make it pass as the original

in addition to the previous request:
is there a lua entity for sam/singleplayer I could use for a texture tester/game piece

[Sokomine]

Yes, the model that is used for the player can also be used for mobs. Some mods do that. Perhaps the Doppelgaenger mod may help you.

Its all about this script:
Github link
The goal is, to kick all online players when the server is about to shutdown. For some reason, its not working, and im at the end with my thoughts about it. Instead of kicking the players in the list returned by .get_connected_players(), it just ignores it and starts looping again. Also the .request_shutdown call is ignored, until all players have left. The process then dies, and thats it.
The first time while testing, the shutdown request was ignored, due to the fact that i was not running the server as seperate process ( singleplayer started server ). After 'fixing' that, i inserted the kicking code, but its not working for some reason i cannot explain.
Im sure that i missed something, but i can't find it. Would be nice if somebody could point me to it.
So my question: What the cobble am i doing wrong?

You can't just "request" new versions of minetest. 0.5.0 is a long way off, and shouldn't be rushed. The first mod you suggested is possible, that might actually be something I'll give a shot at. As for your second request, try Blockmen's Creatures mod, PilzAdam's Simple Mobs, or MobF.

Hi, im trying to improve my mod and i wanted to add a series of items that upon right clicking on the ground, generates a small hollow cube (probably 5x5) with another block in the middle of the interior (probably on the floor) and a doorway. However i don't know how to do this. If possible could i have some help.
Like this;

The wool represents a block from my mod
Many thanks.

Items can react to rightclick via on_rightclick(pos, node, clicker, itemstack, pointed_thing). For spawning entire buildings, schematics are helpful (place_schematic). If the intended building is as tiny as shown in your sample, using minetest.add_node might also be sufficient.

I plan on using the building shown in the screenshot in my previous post, but each version will have something instead of the red wool. How would I make it so an item spawns the building, I don't know what to do for it; I haven't really played around with these kind of things before. Thanks for the reply.

Is there any way to get an ore to spawn in both stone and desert stone without having to create a seperate minetest.register_ore? Like: wherein = "default:stone, default:desert_stone"?

[paramat]

any way to write a pseudo-air node?

Code: Select all

minetest.register_node("modname:airlike", {
    description = "Airlike Node",
    drawtype = "airlike",
    paramtype = "light",
    sunlight_propagates = true,
    walkable = false,
    pointable = false,
    diggable = false,
    buildable_to = true,
    is_ground_content = false,
})

'is_ground_content = false' will stop cavegen eating the node if the node is added by a mod 'on generated chunk'.

I'm trying to write a mod that plays music at dawn and dusk.

Code: Select all

minetest.register_globalstep(
    function(dtime)
        if minetest.env:get_timeofday() == 0.2
        then minetest.sound_play("sunsong")
        end
    end
)

minetest.register_globalstep(
    function(dtime)
        if minetest.env:get_timeofday() == 0.8
        then minetest.sound_play("sunsong")
        end
    end
)

This doesn't work. I don't know enough to know why.

Second: How would one go about writing a chat_command that stops time? I.E. "/stoptime" to halt the world clock, and "/starttime" to set it going again?

Take a look at my bell mod at github. It does slightly more than you want (plays a sound each hour and repeats it as much times as the time demands).

Second: How would one go about writing a chat_command that stops time?

"/set time_speed 0" ought to do.

minetest.register_globalstep(
    function(dtime)
        if minetest.env:get_timeofday() == 0.2
        then minetest.sound_play("sunsong")
        end
    end

        end
    end
)

This doesn't work. I don't know enough to know why.

globalstep works ca. every 0.05s, I think, so minetest.env:get_timeofday() won't be exactly 0.8 or 0.2. You could use math.floor and check if the play_sound was already started 2s ago to avoid playing it more times.

Something like this should work

Code: Select all

local is_day
minetest.register_globalstep(
    function(dtime)
        local t = minetest.get_timeofday()
        local new_is_day = (t >= 0.2) and (t < 0.8)
        if is_day == nil then
            is_day = not new_is_day
        end
        if new_is_day ~= is_day then
            if new_is_day then
                minetest.sound_play("rooster") -- Dawn
            else
                minetest.sound_play("wolf") -- Dusk
            end
            is_day = new_is_day
        end
    end
)

[Krock]

I would let it only try to work every 10s:

Code: Select all

local is_day
local t0 = 0
minetest.register_globalstep(
    function(dtime)
        t0 = t0+dtime --[dtime] = ms
        if t0 < 10000 then
            return
        end
        t0 = 0
...

"dtime" is a double/float/decimal number, it counts in seconds. (ex. 0.06661337)

Is there any way to get items into bones that are in a detached inventory? I would like to get armor from Stu's armor mod into bones, and I'm using 0gb.us' inventory_plus mod. I don't mind modifying the bones mod itself...

Funny, I'd never even thought about that. You shouldn't really need to modify bones, perhaps use register_on_dieplayer in armor to transfer the detached inventory to main. I think that should work but I will try to add something like that myself, now that bones are in the default minetest_game (since a while back actually)

[NathanRandallHolt]

What does register_ore do if you specify sheet distribution? Does it create various flat deposits like clusters of magnetite and micro line in Dwarf Fortress? Does it create an intermittent sheet of ore that spans the world? If the latter, what determines the altitude of the sheet? Is it the min, the max, the average, or something else? Could someone provide an example of how to use it?

what value does return 'player:get_look_yaw()' (something between 1,5 and -4,6????) and how can i convert it into 0-360 degree?

[addi]

I tried it out some time ago. I saved the yaw with get_look_yaw and added it back to the player but somehow it didn't work. "It [...] pretty randomly as of now."

uhh it all hurts in my head.
but i get closer to the solution:

that function returns a radiant like this:

Degree-Radian Conversion [Public domain], by Inductiveload (Own work), from Wikimedia Commons

that can be easily converted to degrees :

Code: Select all

local grad = player:get_look_yaw()*180/math.pi

so now i have degrees. but the cero pount is on the left. this can be fixed with this:

Code: Select all

grad = grad -90;
if grad < 0 then grad = grad + 360 end

ok now is the 0° on the top and 180° on the bottom.

but: 270° are on the left side and 90° are on the right side!?

is somebody good in math and is there a way to rotate this ?

one solution could be a switch case with 360 entries... but i hobe there is a better way.

[CWz]

Can someone please tell me what's wrong with this code. I can't seem to get it to work.

Code: Select all

if minetest.check_player_privs(name, {interact=false}) then
    minetest.after(3.5, player:setpos(x=0,y=15,z=0))
end

[Sokomine]

The player:setpos call is evaluated (and thus executed) immediately, and the return value of that function (whatever that may be) is passed on to minetesminetest.after. Use

Code: Select all

minetest.after(3.5, myfunction, player,{x=0,y=15,z=0} )

and do the setpos in myfunction:

Code: Select all

myfunction = function( player, pos )
      if( player and pos ) then
          player:setpos( pos );
     end
end
