I'm making the assumption that you are trying to make Minetest register the node as a default: node. However, the ":" prefix is only for replacing existing nodes, not using other mods to register a non-present node as present in the mod. You can only use this prefix if you are already replacing an existing "default:stone_with_gold". So you'll just have to register it as a default_extra node.

Just my meagre knowledge and guesswork..

Not true. The : prefix disables the name check, so you can use it to add a node called default:stone in a mod called default_extra

-.- Stupid me. I hade a dofile... pointing to mod "default". Fixed now. Works now.

[ABJ]

Wow nice.
I made another mistake.
I COULD HAVE LOOKED SO MATURE! :P XD

Hello, I've ran into a problem with my new mod. See this screenshot here: http://i.imgur.com/7g6rYtE.png
As you can see, some squares are weirdly "highlighted". Here is my code:

Note:I removed the code from here since my issue is fixed.

Can anyone help?

[everamzah]

Perhaps try commenting out default.get_hotbar_bg(0,4.85), or maybe changing it to default.get_hotbar_bg(9,0).

[Nefario]

I commented out that line and it fixed it on one side, had to also comment out

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

"list[current_player;main;9,1.08;8,3;8]" ..

to remove it on the other side.

Thanks :)

Is there any software that helps assemble formspec? (Similar to NodeBoxEditor)

Is it possible to activate "continuous forward" walking within mod API? E.g. to make player move forward, not to change game settings.

Is there any way to find the path of debug.txt?
Similar to minetest.get_worldpath()
I have seen that in some situations this file can be bin or .mintest (personal Linux folder)
In other cases it appears in the same location where the command is used by the Linux terminal
I need a correct method to get the string that path

[ABJ]

Now, I have this idea. The idea is to, in the TNT mod code, to move the particlespawner in add_effects function behind the timer on tnt_boom registering. The effect I desire to achieve is to have the TNT fireball only visible for the first half second and then delete it and generate the smoke cloud. With all the variables that are used in the main add_effects function, would this even be a good idea? If not, how can this be done?

BrunoMine, maybe this could give the path of debug.txt:
local path = io.popen"pwd":read"*all".."/debug.txt"

btw, try following command:
$ locate debug.txt

[BrunoMine]

BrunoMine, maybe this could give the path of debug.txt:
local path = io.popen"pwd":read"*all".."/debug.txt"

The first command worked perfectly.
I tested it running the same minetest via a link (on the desktop), by terminal and the actual executable. He always returned the path where the debugger is.
The problem is that the string follows a line jump at the end.

btw, try following command:
$ locate debug.txt

I tried
io.popen"locate debug.txt":read"*all"
returned many separate paths for line jump

I am 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

local debug_path = io.popen"pwd":read"*all"
debug_path = string.split(debug_path, "\n")
debug_path = debug_path[1]

What continous moveto does exactly http://dev.minetest.net/ObjectRef:moveto ?

[BrunoMine]

local path = io.popen"pwd":read"*all".."/debug.txt"

there is a way to find the binary that is being used to run the minetest server?

[Hybrid Dog]

ABJ, ask the question there: https://github.com/minetest/minetest_game/issues
but please don't be sad if conservatism is performed there again

BrunoMine, string.sub works better (a lot faster) than string.split:
local path = io.popen"pwd":read"*all":sub(1, -2).."/debug.txt"
l assume there is a way to find the binary, l don't know it.

Is there a way to change the default stack size from 99 to another value in general, or do I have to add stack_max to each item and block?

[KCoombes]

Is there a way to change the default stack size from 99 to another value in general, or do I have to add stack_max to each item and block?

Yep, it's a value in the definition of the craftitem (I searched the dev.wiki for "stack_max" and this was the only result)

[rubenwardy]

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

minetest.nodedef_default.stack_max      = 123
minetest.craftitemdef_default.stack_max = 123


will set the default stack_max for any items registered after those lines are run to the value you give.
To set the stack max of those before, you'll need to iterate through the registered_items

There was a PR to allow a minetest.conf setting to customise stack max, but it was closed due to implementation details and not wanting to update it: https://github.com/minetest/minetest/pull/1843

[BrunoMine]

I know it can be very complex, but is part of a mod I'm doing.
It is possible to destroy a socket to make sure it is free again when the server starts?
I do not know if there is some kind of method C in the minetest. Is there any way to accomplish this?

(Maybe using some command in the shell as well)
assume linux
Thank you

How hard would it be to create an Internet mod?

I mean, would you use node metadata (like shared chests)
to create a sort of "wireless channel?" not unlike a digiline's wired version?
Also, could this be used to interface to Mesecons to create a switch that can
be controlled from afar?

I am currently working on something like that. I will create a forum post soon when the core features are all implemented. Repository: https://github.com/gejan/dcircuits

Ok, I'm having a strange issue - I have created a mesh (16x32) and texture (16x32) for a node, with selection_box and collision_box set appropriately tall - the inventory and wield images are perfect, using the same texture file - but placed in the world, only the bottom 16x16 of the mesh is showing, and without the corresponding texture - is there a way to stretch the mesh to fill the top half (or show the top half of the existing mesh), with the full texture file being used?

screenshot attached

[pithy]

@KCoombes:
Meshes can be made as large as you want and will extend past one node.
It could be an issue with the mesh file.

Mesh file created with NodeBoxEditor (.obj format), but thanks - I'll check it out.

[rubenwardy]

After exporting an obj from NBE, you should take it to a UV wrapping program such as Blender. If you don't need to UV wrap it, just export it as a node box

[Gerald]

Node metadata behaves unexpected:
If i use meta:set_string("key", nil) the field is removed, but if i use meta:set_int("key", nil) key is mapped to zero. I feel uncomfortable using nil as argument and set_string() to remove a field which was set using set_int(). Is there a better/correct way to delete fields?
