Random song of choosing on load?

[Armaetus]

Say I want to make a music WAD with multiple renditions of the same song (IE D_RUNNIN, D_RUNNI2, D_RUNNI3, D_RUNNI4, etc) but want the game to randomly choose one of those and loop it for the duration of the level and repeat the same with the next track (D_STALKS, STLKS2-4, etc)

Is this possible?

Probably with an ACS ENTER script of some type that checks the current map number and chooses from an array of song lump titles.

I didn't test this script, but you could try if it works. This picks from 3 random music tracks for each of 4 maps. I don't know how to get around the switch/case block because afaik, ACS can't mix two different strings together.

Code: Select all

str randomMusic[4, 3] = {
                            {"map01_1", "map01_2", "map01_3" } //or rename them to d_runnin, d_runni2, d_runni3 if you want to.
                            {"map02_1", "map02_2", "map02_3" }
                            {"map03_1", "map03_2", "map03_3" }
                            {"map04_1", "map04_2", "map04_3" }
                        }

script "randomMusic" ENTER
{
    switch(GetLevelInfo(LEVELINFO_LEVELNUM))
    {
        case 1:
        ChangeMusic(randomMusic[1, Random(1, 3)], 0 ,0);
        break;

        case 2:
        ChangeMusic(randomMusic[2, Random(1, 3)], 0 ,0);
        break;

        case 3:
        ChangeMusic(randomMusic[3, Random(1, 3)], 0 ,0);
        break;

        case 4:
        ChangeMusic(randomMusic[4, Random(1, 3)], 0 ,0);
        break;
    }
}

You don't need to concatenate strings. I tested this version.

#library "randMus"

str rndMus[4][3] = {
                            { "map01_1", "map01_2", "map01_3" },
                            { "map02_1", "map02_2", "map02_3" },
                            { "map03_1", "map03_2", "map03_3" },
                            { "map04_1", "map04_2", "map04_3" },
                        };

script "randomMusic" ENTER
{
        int lvlNum = GetLevelInfo(LEVELINFO_LEVELNUM);
        int rnd;
        if (lvlNum <= 4) //don't want this blowing up at the end of the song array
        {
            rnd = Random(0, 2); //arrays are zero-indexed in ACS
            SetMusic(rndMus[lvlNum - 1][rnd]); 
        }
}

Why is this an enter script for a global, non-player, action? This is what open scripts are for.

[Arctangent]

To be fair, it could also be fixed with LocalSetMusic instead of SetMusic, too. That'd mean each player gets to roll for which music file is used, instead of all of them using the same one.

I tried that. It didn't change the music.

I didn't think of LocalSetMusic().

[edward850]

Really? Because it works perfectly fine. Why would it not work?

[Aliotroph?]

Turns out using "open" works with SetMusic(), but not LocalSetMusic(). That was my mistake when I changed two things at the same time and didn't pay enough attention.

[edward850]

Well no, because that's a player function.

[Aliotroph?]

Yeah, I forgot I changed that one. I then stared at the two otherwise superficially different versions of the script for a while and didn't see my mistake. Dumb.
