Sound mp3. Yours, background music in mp3 format, on your map.

I'm just shocked, on a website, there are no lessons about sounds.
We need to fix this.

Sound mp3 with the use of ambientPlay (music plays continuously until the very end with a repeat, there is no default music).
The music file must be in mp3 format

In the folder raw/soundaliases we create the file mp_tutorial.csv. In it we insert this:

The sound should be put in the folder raw/sound/ambient/

Now go to mp_tutorial.gsc file and change in the line ambientPlay value in parentheses to "ambient_mp_tutorial" Should look like this:

Now open the zone file in the compiler
And we add:

Instead of mp_tutorial - the name of the map, respectively

The penultimate step is to go to usermaps / mp_tutorial and create the sound / ambient folders, copy the song there and archive this folder as a zip archive named mp_tutorial.iwd

The last step is to remove the default music:
It's best to create a separate .GSC file, well, call it eg: _killmusic.
We paste in it what is written below:

Naturally do not forget, the new .GSC files of your scripts should be:
if multiplayer, then in the directory: raw / maps / mp / _killmusic.gsc.
if a single-user mode, then in the directory: raw / maps / _killmusic.gsc.

Now in the main mp_tutorial.gsc file, you need to add this line:

It should look something like this:

Now open the zone file again in the compiler
And we add:

Now we can compile the fast game file and add them to usermaps / mp_tutorial.
And accordingly we add this whole thing to some MOD, and through the mod we launch the map, and we enjoy our music.
