is it posible to put a texture for each side like this: (say, for a stone node)
and for the other side (blue=north, red=west, yellow=top, ECT) and if so *Can I have some code**pretty please!*

Of course, it's possible, look here for the code:
https://github.com/minetest/minetest_ga ... s.lua#L683

[hoodedice]

tiles — Specifies the textures used for the node's faces. It's an array (table) of either one or six elements. If only one texture is needed, it can be specified directly as a string instead of a table. The textures are specified as strings as either "texturename.png" or "texturename". The order of the textures is +Y, -Y, +X, -X, +Z, -Z. In English: top, bottom, right, left, front, back.

Does anyone know the mod where you break the bottom of the tree block and the whole thing falls. Do you know where that is and if you do can you put a link down?

It's called timber mod

Need a link? Here is it

Haha, thanks

Does anyone know where I can find the hunger bar mod?

So, while trying to modify paramat's floatindev mod, I ran into a very vexing problem: Many of the blocks that the voxelmanip generates, including default:gravel and a couple moreblocks nodes are added to the world as fire:basic_flame. However, other blocks that I added such as obsidian and dirt_with_snow are generating perfectly fine. Near the beginning of the code, I check to see if moreblocks is installed before redefining the nodes from it I'm using so as to turn is_ground_content false. Does anyone know what could be causing this?

I ran into the same problem couple of times too, the reason from what i checked was a unknown node being generated, e.g. i accidentally spelled "default:wood" as "defautl:wood" <-- (Unknown node). The voxelmanip strangely generates fire:basic_flame instead of a unknown node, look through your code and check the spelling of the node names being generated, you ought to spot some mistakes.
EDIT: didn't saw Topywo post above, and yeah the link basically explains what happens

[Kilarin]

Is that a bug, or a really awesome looking feature! :)

[Casimir]

When using the LuaVM you don't work with the node names but the contend id. Fire has some special number (either zero or one) and therefor is used when there is an invalid id. So make sure you get the right id and there is no typo. Kind of funny that a small mistake can make the whole world go into flames.

I'm trying to make small pools of oil, rather than that mess you can see there, anyone got a fix to it to make it a real pool of liquid?

If you use the sheet ore generation, you could use minetest.on_generated and perlin instead.

[DeepGaze]

what is wrong with this and how can i fix it:

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("bloop:console", {
  -- ...
  on_punch = function(pos, node, puncher, pointed_thing)
    puncher:setpos({bloopxyz})
  end,
  -- ...
})
bloopxyz = "t/xyz"
minetest.register_chatcommand("t/xyz", {
    params = "bloopxyz",
    description = "send bloop to",
    privs = {bloopcontroller=false},
    func = function(name, param)
        bloopxyz = param
        minetest.chat_send_all(name.." sets the value to "..param)
    end,
})

[Casimir]

Is there a way to change how many items the middle click takes/places? I don't think so, so take this as a feature request.

@ DeepGaze
A position is a table {x, y, z}. When you do "bloobxyz = param" then you only have a string. Look into "minetest/builtin/chatcommands.lua". I think you can copy-paste most of the teleport command.

Thanks for the help. After posting this last night, I kept at it for about half an hour more, and found the problem. I knew it was relating to unknown nodes, but since I double checked my spelling and the names of the mods, I knew it was a logic error. And indeed it was. At the start of my code, I had something along these lines:

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 mblocks = false
if (minetest.get_modpath("moreblocks")) then
     mblocks = true
end

What my error was, is that the logic statement was never run since it was not in any function. Silly error, but after correcting it, everything is going good. Volcano biomes with optional coal_stone depending on mods installed are now working. This error has one more benefit: I'm thinking of purposely adding fire to that biome as a surface generation similar to grass. :P

There is no "get_id()" function for entity in "lua_api.txt" .
But "minetest.luaentities" returns id`s of active entities.

So, how I can get id of "richt_clicked_entity" and get entity by id?
Of course, I can get entity by id just using

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

function get_entity_by_id(id)
for k,v in pairs(minetest.luaentities) do
        if k == id then
         return v
   end
end

, but it`s not efficient way, if there is a lot of active objects.

Hi

I've made a nodebox but the correponding image hasn't the correct orientation in the inventory.

Is it possible to turn the automatic inventory image ?

I've just found this http://dev.minetest.net/minetest.inventorycube but i don't want to do an image myself.

     mblocks = true
end

Short it.

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 mblocks = minetest.get_modpath("moreblocks")

Returns string or nil. Doesn't matter, you can use it the same way as boolean.

Good idea, thanks! I'll implement that in the code. Will that run outside of any functions?

I highly recommend LuaEdit. I've been using it extensively, and it has many basic features that really help out. Plus, WordPad doesn't have syntax highlighting.

[LionsDen]

I have Windows XP and use Notepad++ for my text editing needs. It has syntax highlighting and works well for my needs.

WordPad isn't good for modding. You need a syntax highlighter.
I'm using Notepad++ like LionsDen, that one also supports other languages like python, batch and php...

[MrIbby]

Thank you all very much! I tried using LuaEdit, but it doesn't let me highlight large selections with double click... Notepad++, however, is very easy to use.

Is it possible to add items to chests when a abm turns a random node into a chest? I've added a block that turns into a chest, and tried several ways of filling it, none of which have worked... What I want is a few (random) items inside a chest, which is added to the world via an abm. Other ways of adding a chest with things in would work as well. Thanks!

[Kilarin]

I would like to be able to, under certain circumstances, set the players yaw to match a vehicles yaw.
Actually, I wouldn't HAVE to change the players yaw, I just need to make the camera direction change to match the direction the vehicle is moving. (when the player has deliberately chosen to lock their view to the vehicles)

But I can't figure out how to do this through lua. I can do a setyaw on an object, but it doesn't seem to work on a player. There is a get_look_yaw() function, but no set_look_yaw() function.

Is there a way to do this, or have the developers chosen that it is not wise to let mods change the players yaw or the camera direction?

thanks!

Thank you, that's what I needed! It's not documented in the regular part of the developers wiki.

What I want is a few (random) items inside a chest, which is added to the world via an abm. Other ways of adding a chest with things in would work as well. Thanks!

Well, the way I would try it is to define your own treasure chest with a second abm, have your current abm spawn the special chest, then use the new abm to call inv = minetest.get_inventory() on the new node, generate a random ItemStack, then call inv:add_item() to add the random itemstack, and loop it over as many times as needed. Once that is done, swap the node with a regular chest to stop the abm.

[Kilarin]

yet another yaw question.
player:get_look_yaw() and player:set_look_yaw() don't seem to be using the same offset.

When I do a set_look_yaw(1.57) and follow up with a get_look_yaw, the value returned is 3.14. Setting 3.14 returns 4.71 etc. It looks like the values returned from get_look_yaw are offset by +1/2 pi from the values put in to set_look_yaw.

Why?

Do you have any example code? I'm not to good at "complex" things... Thanks for your help!
