A question about:

Settings: An interface to read config files in the format of minetest.conf
- Can be created via Settings(filename)
methods:
- get(key) -> value
- get_bool(key) -> boolean
- set(key, value)
- remove(key) -> success
- get_names() -> {key1,...}
- write() -> success
^ write changes to file
- to_table() -> {[key1]=value1,...}

the question is:
I can query a file type. "conf", called, for example: "player_radar.conf", which is located in "/ minetest / games / mod / player_radar / player_radar.conf"?

Perhaps I misunderstand this API, I thought I could use
local radar_configuration minetest.Settings = ("/ minetest / games / mod / player_radar / player_radar.conf")
since the API says:

"Can be created via Settings (filename)"

I'm wrong? what?

[Krock]

local radar_configuration minetest.Settings = ("/ minetest / games / mod / player_radar / player_radar.conf")

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 radar_configuration = minetest.Settings("/ minetest / games / mod / player_radar / player_radar.conf")

[pandaro]

local radar_configuration minetest.Settings = ("/ minetest / games / mod / player_radar / player_radar.conf")

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 radar_configuration = minetest.Settings("/ minetest / games / mod / player_radar / player_radar.conf")

excuse for imprecision syntax, however this time I typed:
"local radar_configuration = minetest.Settings("/minetest/games/minetest/mods/player_radar/player_radar.conf")"
Terminal says:

"17:47:46: ERROR [main]: Servererror: LuaError ... p/minetest/0.48/bin/../games/minetest/mods/test/init.lua: 25: attempt to call field 'Settings '(a nil value) "

any of you have an example to share?

[wtfsamcrap]

I have a confesion to make .. i cant make new nodes or tools or mapgen for a mod but any other lua works fine how do i fix this

[pandaro]

sorry, solved by myself. The correct syntax is:
local radar_configuration = Settings("/home/p/minetest/0.48/games/minetest/mods/player_radar/player_radar.conf")
AS THE API SAYS!

You can't from Lua. You need to edit the engine sources (C++).

about:
object.get_armor_groups()
this API works?

It should. can you paste some code?

the terminal says me:

I tried with:

print(dump(user:get_armor_groups("fleshy")))
print(dump(user:get_armor_groups([fleshy])))

No, its not implemented yet.

[pandaro]

ok thanks to all

[Casimir]

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

Found it. I had to use "dir" instead of "direction". But dir=1 looks like there is still some work to do.

can someone explain to me how to get node name using lua Voxel Manipulator, place node in certen position with it, and what

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

VoxelManip: An interface to the MapVoxelManipulator for Lua
- Can be created via VoxelManip()
- Also minetest.get_voxel_manip()
methods:
- read_from_map(p1, p2): Reads a chunk of map from the map containing the region formed by p1 and p2.
  ^ returns actual emerged pmin, actual emerged pmax
- write_to_map(): Writes the data loaded from the VoxelManip back to the map.
  ^ important: data must be set using VoxelManip:set_data before calling this
- get_data(): Gets the data read into the VoxelManip object
  ^ returns raw node data is in the form of an array of node content ids
- set_data(data): Sets the data contents of the VoxelManip object
- update_map(): Update map after writing chunk back to map.
  ^ To be used only by VoxelManip objects created by the mod itself; not a VoxelManip that was
  ^ retrieved from minetest.get_mapgen_object
- set_lighting(light): Set the lighting within the VoxelManip
  ^ light is a table, {day=<0...15>, night=<0...15>}
  ^ To be used only by a VoxelManip object from minetest.get_mapgen_object
- calc_lighting(): Calculate lighting within the VoxelManip
  ^ To be used only by a VoxelManip object from minetest.get_mapgen_object
- update_liquids(): Update liquid flow



means?
I have serched and read over things as much as i could but there is not much infomation about this. What i want to do is to get large box as 2 position, read exactry how many of what is in that large box that is diggable and what is drops, turn it all in to air and keep the liquid, then place them in chest like stuff organised. (i'm trying to make technic quarry like thing that charges like battery and digs instantly when fully charged.)

ps
someone need to make developers wiki page about Lua Voxel Manipulator.

I've a simple question:

How do I check if the node "X" contains items/nodes in it?

[PilzAdam]

I've a simple question:

What do you mean by "contains items"? An inventory like a chest?
The node's inventory is in the meta, that can be gotten via:

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 meta = minetest.get_meta(pos)
local inv = meta:get_inventory()


Then it depends on the node in which list the content is, e.g. for a chests its in "main".

Well, I mean like the chest or furnace, but I need a general checking if there is something stored or not..else will my new node erase everything in it.

Hmmm... I dont know how to get a list of all used listnames in that inventory.

[Krock]

Hmmm... I dont know how to get a list of all used listnames in that inventory.

Or is there another way then with listnames? I've tried with meta:to_table() but that does not work...

I guess something like this could work:

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 listname,list in pairs(meta:to_table().inventory) do
    for index,item in ipairs(list) do
        -- do something with item
    end
end

okay thanks, I will try.

I need to execute a function when I put an item in the first row of the inventory of the player. Inventory of reference should be current_player, main. So I should redefine the function on_put () for inventory, "current_player"

is this possible?

You might look into the "flashlight" node/tool of the technic mod:

I do not think that's what I try. I have to run a function when a player put an item in the first row of the inventory. I do not want to use a "globalstep" because it is computationally exaggerated.


Then I still try to change "on_put" of the inventory of the player.
I discovered that through minetest.get_inventory ("player", "name_of_the_player")I can get a reference.
At this point can i change "on_put" for this player? or even for all players?

Is it possible to spawn an ore in the air because wherein = "default:air", doesn't seem to work

[kaeza]

Is it possible to spawn an ore in the air because wherein = "default:air", doesn't seem to work

The node name for air is "air", not "default:air". See if that works.

It worked, thanks. Another question: is it possible to spawn something that isn't random, like a house or somethin, and how?
