Instead of using g() you can just write
var = minetest.setting_get(value) or default
Much shorter than defining g().

license question:

if i use a mod or parts of a mod in my subgame,
but i edit/change the mod content, what do i write into the "license.txt"?

[Desour]

@DS-minetest: Your signature uses the word too. I do not think it means what you think it means.

is it better now?

@Linuxdirk: To add a setting to the configuration UI see settingtypes.txt in lua_api.txt.

So settingtypes.txt isn’t for games only but mods can use it, too? But I guess with this I still have to make sure to use some kind of validation of the used configuration option actually exists in minetest.conf, right?

var = minetest.setting_get(value) or default

Currently it isn't for better flexibility but g() could be extended to automatically prefix the option. Writing local var = g('parameter', 'default') to me is much shorter than writing local var = minetest.setting_get('my_cool_mod_pefix_parameter') or 'default' …

Of course it makes no sense to use a function when only requesting one or two parameters. But I use this function in my entire mod pack and all of the possible values are configurable through options.

Yes mods can have a settingtypes.txt to.

If it is not in minetest.conf then the value is nil.

Germans like to use the word too.

Just checked and rewrote my modpack so it uses the file. Too bad it's stated nowhere that this is possible for mods, too.

Google Übersetzer funktioniert gut.

Question:
If I wanted multiple blocks to be placed when I place one block, how would I make that happen? Also dependent on what direction player is facing?
eg- place one block and 2 "spawn" stacked on top and 3 "spawn" stacked next to it
[][]
[][] <------like that
[][]
^
Say that is the original block.

[D00Med]

When the block is placed(on_construct), check if the block beside is empty(ie: air), and then use minetest:set_node(pos, {name="nodename"}).
Like this:

Code: Select all

on_construct = function(pos, node, _)
		local under = {x=pos.x, y=pos.y-1, z=pos.z}
		if minetest.get_node(under).name == "air" then
		minetest.set_node(under, {name = "test:node"})
		end
	end,

But I don't know about making it dependant on the direction the player faces

I think it is probably better to place them as schematics

EDIT: Figured that out, but the amount of blocks placed is infinite in that direction until obstructed... also, sounds don't seem to work. Keeps saying 'default' is nil in the default.node_sound_wood_defaults().

[D00Med]

Oh yes I forgot to mention that, just make it check if there is not already a the same node 2 nodes above.
have you listed default as a dependancy?

[pithy]

How do I use listcolors twice in a formspec?

[orwell]

You mean upper inventory blue and lower red?
I think this isn't possible as of now.
But you could make a background and make slot background transparent

[pithy]

^Thats what I was thinking I might have to do.

Hi folks )
Is it right if attached entity (to other entity) disappear after restart singleplayer game ?

simplified code here:

Spoiler

Code: Select all

	
local a = minetest.add_entity( pos, Proto)	
local b = minetest.add_entity( pos, Proto)	
	
b:set_attach( a, "", {  x=10,  y=0, z=0},    {x=0, y=0, z=0}) 

[Desour]

i think no, it only gets detached

[GreenXenith]

Is there an on_player_construct function or anything? Using on_construct makes an infinite tower. If there was a construct function specific to a player placing a block, I would like to know what it is.

[pithy]

Use "after_place_node" in the node def.

[GreenXenith]

Gave up on what I was doing. :P

Is it possible to override a chat command registered by a mod to check for a condition? If so, how do I target it? Or would it be better to override the entire mod?

[orwell]

Yes you can, and that's cool about lua. You should avoid this practice, but here's how:
1. depend on the mod that registers the chatcommand, so that it loads first
2. take it and modify the function:

Code: Select all

local original_func = minetest.chatcommands["chatcommandname"].func
minetest.chatcommands["chatcommandname"].func = function (name, param)
        if your condition here then
                original_func(name, param)
        end
end

It's important that you understand what you're doing:
you are saving the original function that the mod registered as local variable, then you define a new function that replaces the original chatcommand's function with the above code.
if you condition is true, you call the original function.

For Wild-West - themed buildings, I would need big signs on houses,
such as "Bank", "Saloon", "General Store", etc.

Obviously, I could make textures with parts of such a text,
(or just single big letters) to put on blocks.

Is there a better / more general way than to do it ?
E.g. a block made of 2 different materials, and a surface-pattern,
that makes it look like those ore-blocks. but shaped like a letter/symbol.

There is a mod for traffic-signs, and an idea for a sign-making machine, but still WIP.

[orwell]

You could make one big mesh and place the sign texture on it. That mesh would then span ~5 nodes but only occupies the node you placed it to.
The homedecor soda vending machine is actually a mesh being 2 nodes high and having a texture. Or have a look at the rails from my trains mod.
- model it in blender and unwrap (detailed info on how to make textures for models you find on youtube)
(1 blender unit equals 1 node)
- export as b3d and write SALOON on the texture
- make a drawtype=mesh node in MT.
