Well,I finally bookmarked your modding book Sir Ruben Wardy XD, It's a very useful reference material.
So, at end the code seems like that:

Code: Select all

local sound = 'no'
minetest.register_tool("headphones:1headphones", {
   description = "Headphones Test Song",
   inventory_image = "testh.bmp",

   on_use = function()
        if sound == 'no' then
            sound = minetest.sound_play("test") --keep the "reference" of the sound
        else
            minestes.sound_stop(sound) --stop the sound
            sound = 'no'
       end
   end,
})

Not really, you just need practice.
make little challenges to yourself:
exercises, big projects, read some good book/e-book (not only about Lua),
It comes along with time, so be patient.

And of course think out the box :D
creativity helps to find a nicer way to solve a problem.

I agree! I have been slowly learning. I still have a lot more to learn. Every challenge I give myself makes me have a little more knowledge. Keep trying.

Remember that failing is much better than not trying at all. Some of the best things in life are the result of failures.

Good advice...

Many people said that to me too...

Question: How to post a topic?
Reason: I want to release a mod.

[kaeza]

For length: #str
For character: str.sub(i, 1)

Correction: `str:sub(i, i)`

Arguments are start and end pos, not start pos and length.

[...]I want to create a verification loop of characters in a string.

Patterns are probably faster. For example, this code tells you if you have any non-alphanumeric chars:

Code: Select all

if str:find("[^A-Za-z0-9]") then
  error("please only use letters or digits")
end

Read more about patterns here.

Edit: If you need to know the position for whatever reason:

Code: Select all

local start, fin, what = str:find("[^A-Za-z0-9]")
if start then
  error("character "..what.." (at position "..start..") is not allowed")
end

[jp]

This would be even simpler using :

Code: Select all

str:find("%W")

You release a mod in the wip mods section.
When the mod is complete and the forum topic is set up following the guidelines then you request that your mod gets moved to releases.

How can I place an item in a biome.
For example: I want to appear in a chest in a jungle forest.

I can not check the area next to jungle trees that have just been generated.

Are you trying to do it when the map loads or could you use an abm or lbm to make it place?
