Assets Declarations

To play a sound, you must first add the file to your assets/sounds/ directory and then declare it. To do so, Monogatari has a function that will let you declare all kinds of assets for your game.

monogatari.assets('sounds', {
    '<sound_id>': 'soundFileName'
});

Supported Formats

Each browser has its own format compatibility. MP3 however is the format supported by every browser.

If you wish to use other formats, you can check a compatibility table to discover what browsers will be able to play it.

Loop Sound

The following will play the sound, and once the sound ends, it will start over on an infinite loop until it is stopped using the Stop Sound Action.

Script

monogatari.script({
    'Start': [
        'play sound riverFlow with loop',
        'end'
    ]

Fade In Effect

The following will play the sound with a fade in effect.

Custom Volume

The following will set the volume of this sound to 73%.

Script

monogatari.script({
    'Start': [
        'play sound riverFlow with volume 73',
        'end'
    ]
});

Sound Assets

Please note that the user's preferences regarding volumes are always respected, which means this percentage is taken from the current player preferences. If the player has set the volume to 50%, the actual volume value for the sound will be:

$$50\% \times 73\% = 36.5\%$$

Resume Paused Sounds

If sounds have been paused using the Pause action, you can resume them:

'play sound'  // Resume all paused sounds

All Together

You can combine all properties. The order doesn't matter.

Script

monogatari.script({
    'Start': [
        'play sound riverFlow with volume 100 loop fade 2',
        'end'
    ]
});

Audio Effects
