Lua script audio when starting game (Urwigo)

[+Richard en Monja]

Hello,

 

I am new to Wherigo cartridges en lua scripts..... I looking for an lua script that plays a mp3 soundfile once at startup of a game.

 

Thanks in advance.

 

Richard.

Try to use a Wherigo-builder like urwigo. These have defined many methods. Also one to start an audio.

Thanks for the reply, but what I want is following:

 

Before Wherigo.ShowScreen(Wherigo.MAINSCREEN) I want to add an lua script to play an audio mp3 file.

 

If I add an audio file with Urwigo "Play Sound" than it plays the mp3 file, but then the game does not start up anyfurther.

 

When the Lua script is added  directly in the Lua user functions it might work.

 

Thanks in advance.

I would use the blocks for anything I can. I only use lua source code for arrays or moving zones - it's easier;)

 

To see how a sound is played you can try the following:
1. Create a cartridge that plays a sound in the onStart event
2. Create a .gwz file
3. Unzip the .gwz file
4. There should be a lua file. Search there how Urwigo implemented the play sound file.

 

(Sorry for my english. I used google to translate.)

If my memory serves me right, you first must create a Wherigo.ZMedia object and pass your cartridge to its constructor.

audio = Wherigo.ZMedia(cart)

You then must set its Resources field accordingly.

audio.Id = "00000000000000000000000000000000"
audio.Name = "Sound Effect" -- the Name and Id fields probably aren't strictly 
                            -- necessary, but I've never tested that myself so
                            -- I'm not sure. Some players may crash w/o them.
audio.Resources = {
    {
        Type = "mp3",       -- waveforms (wav) should also be vaild.
        Filename = "path_to_effect_in_gwz.mp3", 
        Directives = {}
    }
}

To play the audio, you can call the Wherigo.PlayAudio method, and pass the audio object instance as the first argument.

function cart:OnStart()
    Wherigo.PlayAudio(audio)
end

As a precaution, though, you should probably follow the steps described by @capoaira above and figure out how the regular builders implement this.
