question about box in formspec, the API call:
box [<X>, <Y>; <W>, <H>; <color>]
^ Simple colored semitransparent box
^ X and y position the box relative to the top left of the menu
^ W and h are the size of box
^ Colorkey (see colorkeys)

So I tried it with:
"box [6.6, 1.1, 0xFF0000]"
or
"box [6.6, 1.1; FF0000]"
or
"box [6.6, 1.1; 000000]"
  and with other various forms of color definition. Minecraft always responds:


13:21:02: ERROR [main]: Invalid Box element (3): '6, 6, 1.1, 0xFF0000 'INVALID COLOR

Someone very kindly know the proper way to use the colors in the definition of a box within a formspec?
I hope you understand me.

EDIT!!
i need the latest git version up to use rgb colour definition.
the answer to my question is: update minetest!

My concrete 2.2 mod seems to shut server down when you dig the concrete.
Code causing the problem most likely is...

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_node("concrete:concrete", {
    description = "Concrete",
    tiles = {"concrete_concrete.png"},
    is_ground_content = true,
    groups = {cracky=1},
    drop = "concrete:gravel_mound",
    after_destruct = function(pos)
        minetest.env:set_node(pos, "concrete:concrete4")
    end,
})

    tiles = {"concrete_concrete.png"},
    is_ground_content = true,

can you find the problem?

~~~~
minetest.env:set_node(pos, "concrete:concrete4")

Yes, set_node and add_node take a table containing the fields 'name', 'param1', and 'param2'.
Also minetest.env:* was moved to minetest.*.

minetest.set_node(pos, {name="concrete:concrete4"})

Note: Technic also has a concrete mod, so watch out for conflicts.
Edit: Nevermind, it is under the technic namespace.

Is there any way of running a certain lua file when a certain node is placed? So: If I placed mymod:mynode it would do the file mymod_second_part.lua
Also, is there any way of making it so only one of mymod:mynode can be placed in the world?
Lastly, can I make it so that if a stone node has air above it, every five seconds it has a 1/5 chance of spawning a fire node (ABM perhaps)

Please PM me with any answers.

Is it possible to put a modpack inside of other modpacks?

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.

There is a configure button in the start screen of Minetest. With that you can decide what mods you want installed and what mods you don't. Hope this helps.

Is there any way of running a certain lua file when a certain node is placed? So: If I placed mymod:mynode it would do the file mymod_second_part.lua

see after_place_node in register_node. The function is usually used to setup nodes (i.e. set their owner).

Also, is there any way of making it so only one of mymod:mynode can be placed in the world?

Yes, but that takes more effort. You could store the information where the exclusive node was placed in a file in the world folder - and check each time a node of that type is to be placed if the file exists.

Lastly, can I make it so that if a stone node has air above it, every five seconds it has a 1/5 chance of spawning a fire node (ABM perhaps)

Yes, register_abm is the right place to look for.

In which folder is stored the starry sky of minetest?

[PilzAdam]

In which folder is stored the starry sky of minetest?

Its not stored anywhere, its generated at runtime.

[pandaro]

I think about the possibility of creating a starry sky always the same, that would enable the player to navigate at night using the stars.
It would be possible at least in theory?

[paramat]

Hi, i searched but no success ... how would i control the order of execution of 'on generated' functions in various mods? ... dependancies maybe?

[qwrwed]

How do I use add_node or set_node to create other nodes? i am making a plasma screen TV mod which has 6 nodes, arranged like this:
1 2 3
4 5 6
5 is the node that is placed, and when the player places it the other 5 nodes should generate. However, I don't know how to do this, and looking in the code for the stargate mod, doors mod and beds mod did not help - the first two were more complicated, and I don't even know where I'm going wrong using code from beds, so I would like to start from scratch.

[webdesigner97]

If you need your manually placed node to facedir, make sure to add param2 to the node:

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

    after_place_node = function(pos,placer,itemstack)
        --Don't forget to modify the <pos> table
        minetest.set_node(pos,{name="bla", param2=minetest.dir_to_facedir(placer:get_look_dir())})
    end


And for changing pictures: Why not use a texture animation?

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_rightclick = function(pos, node, clicker)
        local inv = clicker:get_inventory()
        if inv:room_for_item("main", {name="flowers:pot", count=1, wear=0, metadata=""}) then
            node.name = "flowers:dandelion_white"
            minetest.env:set_node(pos, node)
            minetest.sound_play("default_dug_node", {pos,gain = 1.0})
            inv:add_item("main", "flowers:pot")
        end
    end,

Everything works, except adding the item. It is added when there is already a stack of flowers:pot in the inventory, but not when there is non.

have you tried removing 'wear=0' from the room_for_item() call? It sounds silly, but 'wear' should only be set on tools (note that '0' is neither nil, nor a "false" boolean value).

[Casimir]

Setting the node and playing sound is working, so that's not the problem.

At the moment I have a much bigger one: I moved a mod into another folder, because I wanted to publish it. Using strg-x and strg-v and then is just disappeared :(
Is is Mint, is it Thunar or is it me who has done something wrong? (Yes, I should have made backups.)
It might be to late at night - I'm very confused - in the game everything still works but the mod-folder is nowhere.

Hello guys,

is it possible to access the tiles that were used on minetest.register_node( <parameters> ) ? I found param1 & param2 as well as the name, but no way to find the registered image files used for that specific tile. Is that somehow possible?
(If i missed something really obvious, sorry for that :-/ )

Greetings

Do you want to change the texture of a node (like stone and desertstone) or the way it is displayed (like papyrus/stone/torch/sign/rail...)?

Do you want to change the texture of a node (like stone and desertstone) or the way it is displayed (like papyrus/stone/torch/sign/rail...)?

I dont want to change it. I need the references to see, if i can create a way of changing the appearance of a node ( with use of a dummy node ) especially its mesh in a way that is not dependent on hard coded links to other mods. As example:
The stairpick mod uses references to the stairsplus stairs. So it looks up the fitting stairs out of this mod in order to replace the node you are pointing to and replace it with the stair.
BUT if you are capable of accessing the tiles of a registered node, you could create a stairpick (as example) that uses no references to other mods. Instead it uses a dummy model of a mesh (also an example) and assigns the texture of the node you were pointing to in the first place.

I hope this will work ( up to now its only a idea)

How do you use the facedir param (param2) of nodes? E.g. how do you make the facedir of a node depend on where the player looked when it is placed?

D'oh.
I looked up the paramtype2 line of my node definition in my code again and saw 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

          sounds = default.node_sound_wood_defaults(),
      paramtype = "light",
      paramtype2 == "facedir",
      on_construct = function(pos)
      ....


Obviosly, that comparision doesn't make for a proper paramtype ;)
I fixed that line, now it works like a charm.
