Question - Code Retrieve audio_group sounds [SOLVED]

[DeveloBert]

Hi all!

Does anybody know if there's some way in GMS2 to retrieve all the sounds included in an audio_group? Basically what I would like to achieve is a piece of code that return a relation of all the sound objects that belong to a particular audio_group.

Thanks!

A simple workaround would be to give the sounds a prefix or suffix to indicate that they belong to one or other audio group, and then loop over all sounds, retrieving those that have it in the name (string_pos\string_copy). I did at one point write a script that would read the game's own executable to get this data, but that's something that breaks as versions advance.

Thanks, @YellowAfterlife That aproach could work. How do I loop overall all sounds in the resources tree?

By doing just

for (var snd = 0; sound_exists(snd); snd += 1) {
    // work with `snd`
}

since sounds are accessed by index.

Cool, I'll try this! Thanks a lot for your help!

Hi again,

In case it helps anyone, here's the final chunk of code I came up with:

var _sound_id = "my_sound_id";

for(var _snd = 0; audio_exists(_snd); _snd++)
{
    var _sound_name = audio_get_name(_snd);
    
    if(string_pos(_sound_id, _sound_name))
    {
        // Your code here
    }
}

Let's say you have the following sounds in the library: "snd_Level1_1", "snd_Level1_2", "snd_Level1_3"

You just need to set the "_sound_id" var to "Level1" and the code will detect all the library sounds which contain that string.

Cheers!
