I have a problem. I tried to do 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

on_punch = function(pos, node, puncher)
        if puncher:get_wielded_item():get_name() == "bucket:bucket_water" then
            minetest.env:set_node(pos, {name="thaumtest:cauldron_full"})
            minetest.env:replace({item="bucket:bucket_empty"})
        end
end,


Just set the wieleded item :

Code: Select all

on_punch = function(pos, node, puncher)
        if puncher:get_wielded_item():get_name() == "bucket:bucket_water" then
            minetest.env:set_node(pos, {name="thaumtest:cauldron_full"})
            puncher:set_wielded_item({name="bucket:bucket_empty"})
        end
end,

Edit:

he was using on_rightclick, not on_punch.

Nope. he changed after the suggestion of Casimir

Thanks everyone! It works now. Idk what I would do without this topic. :D

I am running in to a problem. I want to do the same thing as I did before, except it empties the cauldron into the bucket this time. My problem is that you can't punch anything with an empty bucket. The reason you can't punch anything, is that the only thing you can punch with an empty bucket is water. Since I am using "on_punch" to detect when to take the water out of the cauldron, it doesn't work. Can anyone suggest a workaround for this?

I need help installing mods..i tried several times and it didnt work. is there a specific way of doing it instead of just downloading and temoving it from the file?

Do you use stable 0.4.6? --> http://forum.minetest.net/viewtopic.php?pid=88510#p88510

If you use the latest github version(s) --> http://forum.minetest.net/viewtopic.php?pid=91221#p91221
--> don't forget to 'activate' them with configure

Some other "Usual suspects" for mods (still) not working:
- A folder needs to be renamed to the (low-case) name, used in the init.lua.
Example: VanessaE-homedecor-e5c99a3 --> rename --> homedecor
- Trying to use an older mod version or a not up to date mod version
- Use of an older version of minetest than the latest, unofficial
- Missing dependencies (look in the 1st post of a mod or check the depends.txt file in the mod folder you installed)
- Bugs in a mod

For the life of me I CANNOT MOD.

I am on a 64-bit Windows 7 Toshiba laptop. I use the stable, official 0.4.6 release. I've tried both the installer (in beta) and just extracting it to a folder I named Minetest in WINDOWS (C:).

I know how to install them: it's easy, just extract into the mods folder. But nothing works. The mods simply won't run, even if the game does. Every single time I run a game it's like the mod was never there. I've uninstalled and reinstalled. I even tried PilzAdam's unofficial build. Nothing works.

I'll rename the mods folder like some people say I should with the name consisting only of lowercase letters. That doesn't work either. So what the heck is going on? I even tried to make a simple mod myself, the decowood mod that is used for the creating mods tutorial. That doesn't work either.

I've tried at least two mods, the mob framework and the PilzAdam's Minecraft-like item drop mod. It all refuses to run. Can anyone help? I'll try to give additional information as needed.

If you have (one of the latest) 'unstable' versions, follow the link in the previous post from cHyper.

Afaik you don't need to create a folder to unzip your mods into (although I heard about that, so not 100% sure). You run the risk creating something like /mobs/mobs, which doesn't work.

If you have the 0.4.6 stable version of minetest extract the mods from your download folder by right-clicking and then selecting extract to (maybe unzip to) and then selecting with your file manager that should have popped up one of the following folders:

1. minetest/mods/minetest folder
2.a. minetest/games/build/mods folder.
2.b. minetest/games/survival/mods folder.

1. When you put the mods into the /mods/minetest folder, you need to create a game in the menu choosing Minetest (minetest_game).
2.a. When you put the mods in the /games/build/mods folder, you need to create a game in the menu choosing Build.
2.b. When you put the mods in the /games/survival/mods folder, you need to create a game in the menu choosing Survival.



I you have (one of the) latest 0.4.6 versions (unstable), read this:

http://forum.minetest.net/viewtopic.php?pid=91221#p91221

but first you can try to put the mods in a place that looks like this:
minetest/mods/minetest folder
(like option 1 for the stable version / works at least for a run in place version of minetest) EDIT: or, if that doesn't work move them to the higher minetest/mods folder


If this doesn't help you'll at least need (to try) to specify in a post:
- What operating system you're using (Windows, Linux, ...)
- What version of minetest you've installed (0.4.5, 0.4.6 stable, latest Github version, one of the builds from the forum)
- and if you installed it local or system wide
- exit minetest, delete your debug.txt file, restart minetest, start a game, exit minetest, copy the content of the debug.txt file and paste it in a post.

Sometimes minetest versions and mod versions conflict with each other. It think at least this mod works fine for more versions: http://forum.minetest.net/viewtopic.php?id=5571 (rename it to lavalamp) . It's easier to try out installing with this one (and it's a good looking mod).

How would i access the world seed from within a lua mod?

I want to use the world specific world seed number to define some world specific features generated by mods.
The on generated function has 'seed' but this is the blockseed it seems ...
Many thanks if anyone can help ;)

[kaeza]

you could load that yourself:

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 path = minetest.get_worldpath().."/world.mt"
local f = io.open(path)
if (not f) then error("wut") end

local prefix = "seed ="
local prefixlen = prefix:len()

local seed

for line in f:lines() do
  if (line:len() > prefixlen) and (line:sub(1, prefixlen) == prefix) then
    seed = tonumber(line:sub(prefixlen+1):trim())
    break
  end
end
f:close()

if seed == nil then
  error("couldn't find seed")
end


Untested code.

I was making a better skyblock map, and it seems default does not allow for cobblestone generators. Can anyone link me to a mod that allows for cobblestone generators?

Not a cobblestone generator but obsidian :-)
I took a quick look, seems obsidian generates with source-source and flowing-flowing. I hope it helps you.

No, obsidian doesn't work. I need cobblestone, obsidian is in default.

I believe glooptest has some form of lava+some form of water -> cobblestone
See here: http://forum.minetest.net/viewtopic.php?id=4345

[Nore]

Looking in the code of default, I reckon that lava_flowing and water (flowing or not) will create default:stone. Is it what you need?

Hey, I am working on a mod and I need to know if there is a way to make a furnace not need to use fuel. I am very new to modding, so could you please help?

Hey, I am working on a mod and I need to know if there is a way to make a furnace not need to use fuel. I am very new to modding, so could you please help?

Yes, this is possible. Just copy the furnace code from default and remove the parts where it takes fuel.

Is there a mod that makes items that are dropped on the ground (like the saplings from leaves decaying) automatically go into your inventory when you walk close to them?

How do you make textures work on nodes that have nodeboxes bigger than a node? The only example I could find is the hydro turbine in mesecons, and I don't see anything special in the code.

How do you make textures work on nodes that have nodeboxes bigger than a node? The only example I could find is the hydro turbine in mesecons, and I don't see anything special in the code.

I don't know how to do it. But here's some other examples: the big pumpkin and the scarecrows of farming_plus.

How do I overwrite a node like trees:tree_conifer from Tiny Trees?

I want to do this in my mod Alternative Trunks.

Here's an example of something I tried:

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 cube =    {-0.5   ,  -0.5   ,  -0.5   ,  0.5   ,  0.5   ,  0.5   }

local cylinder = {
                {-0.1875,  -0.5   ,  -0.5   ,  0.1875,  0.5   ,  0.5   },
                {-0.5   ,  -0.5   ,  -0.1875,  0.5   ,  0.5   ,  0.1875},   
                {-0.3125,  -0.5   ,  -0.4375,  0.3125,  0.5   ,  0.4375},
                {-0.4375,  -0.5   ,  -0.3125,  0.4375,  0.5   ,  0.3125},   
                {-0.375 ,  -0.5   ,  -0.375 ,  0.375 ,  0.5   ,  0.375 },
}

if minetest.get_modpath("trees") ~= nil then
minetest.register_node(":trees:tree_conifer", {
    description = "Conifer trunk",
    paramtype = "light",
    tiles = {
        "trees_tree_top_conifer.png",
        "trees_tree_top_conifer.png",
        "trees_tree_conifer.png"},
    drawtype = "nodebox",
    selection_box = {
        type = "fixed",
        fixed = cube,
    },
    node_box = {
        type = "fixed",
        fixed = cylinder,
    },
    groups = {tree=1,choppy=2,oddly_breakable_by_hand=1,flammable=2},
    sounds = default.node_sound_wood_defaults(),
})
end

This doesn't work.
What did I do wrong?
