Okay. If you want everyone to be able to use, edit and distribute the mod, then use GPLv3. If you want any other license, you might try LGPL or some other one. CC licenses aren't really for code...

Yes!
Get to work!

Ok, so I'm putting together a mod for personal use, and I added a food item. But on use of this food item, I want part of it to return back to the inventory (it's soda, I want an empty bottle back). I have no coding experience, so I'm just going on what I see in minetest_game mods and other mods. I have this...

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("morestuff:apple_soda", {
    description = "Apple Soda",
    inventory_image = "apple_soda.png",
    on_use = minetest.item_eat(3),
    replacements = { {"morestuff:apple_soda", "vessels:glass_bottle"} },
})

Can someone tell me where I'm going wrong?

An actual scroll bar that works, maybe but I think it would be very difficult to do. You could however have an up arrow button and a down arrow button and use them to scroll through different inventories. To do something like that I would suggest you study the code for unified inventory which is part of the technic mod.

[Krock]

This worked perfectly, thanks!

Wow, and I didn't even test it :3

Okay thanks, maybe are scrollbars needed somewhen :)

[LionsDen]

I believe that the unified inventory mod is no longer being developed at that thread and is now a part of technic. A sub-mod if you will. At least I remember hearing about that at one point months ago.

[Nightshade]

This worked perfectly, thanks!

Ok, so maybe it didn't work as perfectly as I thought. First what I did was take out my "on_use" then put in yours. that didn't allow the soda to heal. Then I combined the two, but if you tried to drink one from a whole stack, the whole stack was taken. SO, I added a stack limit of 1, and that fixed it. I ended up with this:

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("morestuff:apple_soda", {
    description = "Apple Soda",

    stack_max = 1,
    on_use = minetest.item_eat(4),
    on_use = function(itemstack, user, pointed_thing)
        -- Dig if pointed on node
        if pointed_thing.type == "node" then
            return
        end
        minetest.item_eat(4)
        return ItemStack({name = "vessels:glass_bottle"})
    end,
})

I may look into the code of the farming:bread and change some stuff around later though. :)

i need only one thing: i making on my mod from simple mobs but i dont know how i can set jumping to any lenght , high and speed. Please help me

[pandaro]

'm sorry but I have tried in several ways. I'm not able to change the position of a HUD through "hud_change ()"

EXAMPLE of not working test:

minetest.register_tool("player_radar:radar_hud",{
description="radar hud",
inventory_image = ("portable_receiver.png"),
tool_capabilities = {
groupcaps={
snappy = {times={[2]=0.95}, uses=20, maxlevel=1},
--fleshy = {times={[3]=1.6}, uses=10, maxlevel=1}
}
},
on_use=function(itemstack,user)
player_radar_hud[user:get_player_name()] = user:hud_add({
hud_elem_type = "image",
position = {x=0.5,y=0.5},
scale = {x=0.1, y=0.1},
text = "radar13cmp2.png",
number = 1,
alignment = {x=0,y=0},
offset = {
x = 0;
y = 0;
},
})
end,
on_place=function(itemstack,placer)
placer:hud_change(player_radar_hud[placer:get_player_name()],"position",{x=0.1,y=0.1})
print(dump(placer:hud_get(player_radar_hud[placer:get_player_name()])))
end,
})

someone could pass me an example?

[kaeza]

Pandaro: seems like a typo in the Lua HUD. I have submitted a patch for it.

For now, you can use "pos" instead of "position".

[AMMOnym]

It is possible that it can be from one combination to produce more things as output?
minetest.register_craft({
output = 'poke:magicarp', 'poke:psyduck',->?
recipe = {
{'poke:randomwater'},
{'poke:awakening'},
}

[AMMOnym]

thx

kaeza thanks, it works!
I hope that your patch is accepted.

About the hud; No matter what I set "direction" to, it always looks the same. Could it be that this is not implemented yet?

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_bubbles[name] = player:hud_add({
    hud_elem_type = "statbar",
    text = "bubble.png",
    number = 20,
    direction = 1,
    position = {x=0.5,y=0.9},
    offset = {x=0, y=19},
})

Is there a way to connect two worlds? Has anyone done it? Is it in the realm of possibilities thru lua or is it something I would have to get into the hard coding for?

[Casimir]

Depending on what you want, there are two things I can think of. Both would be possible in Lua.
1. With some portal thing when entered the player file is copied to the second world, in one file there is saved that the player left the world. Then the player is kicked out of the server and can not connect until the "player is not in this world" file is changed from an other world. You would have to manually connect to the new server.
2. A shared build area. When ever a node is altered in the defined area, it is saved in a worldedit file and sent to the second server/world together with a timestamp and then loaded into the second world.

couldn't I make a .js file to use theplayer profile to automatically log the player into the new server?

[fairiestoy]

Question is: What are you exactly aiming at? Do you want to cross-connect several servers by portals? If you just want to give the player the imagination that hes wandering between different worlds, you could create a mod which adds unpassable borders at specific heights and generate new land above this borders. If a player gets ported to the destination, he cannot get back to the original level without the portals. Thats at least the most useable solution ( imo ) when you don't want to kick out the user from his server and force him to reconnect somewhere else ( where he might run into problems when not finding it in the server list for example ).

If you want the crossconnect stuff ( which is interesting ), you have to suggest a API facility to the devs ( like minetest.client_connect_to( <connection parameters> ) ) which holds the current connection but tries to get the user into the other server. On success, he gives free the original connection. Should be a client-only thing.

Topic: Can someone put this C# code into LUA?
Reason: Mods
More Info: This here is the 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

//for the 3D-coords
struct Position {
     public int x, y, z;
}
//node
struct Node {
     public int param2;
}
//nplayer
class Player {
     //just pointing to the existence of this
}

//now the codes
void testing(Position pos, Node node, Player player) {
     for(int x = pos.x - 1, x <= pos.x + 1, x++) {
     for(int y = pos.y - 1, y <= pos.y + 1, y++) {
     for(int z = pos.z - 1, z <= pos.z + 1, z++) {
          Position xpos = new Position();
          xpos.x = x;
          xpos.y = y;
          xpos.z = z;
          minetest.env:remove_node(xpos);
     }
     }
     }
}


In short: it should dig a 3*3*3 block, without changing the "pos" variable.

[Krock]

function dig3(pos)
for i = -1,1 do
for j = -1,1 do
for k = -1,1 do
minetest.remove_node({x=pos.x+i, y=pos.y+j, z=pos.z+k})
end
end
end
end

Oh thanks, I simply thought too much.
