Phaser . Sound . NoAudioSoundManager

This is a beta release of our new docs system. Found an issue?
Please tell us about it in the #📖-newdocs-feedback channel on the Phaser Discord

Phaser . Sound . NoAudioSoundManager

No-audio implementation of the Sound Manager. It is used if audio has been disabled in the game config or the device doesn't support any audio.

It represents a graceful degradation of Sound Manager logic that provides minimal functionality and prevents Phaser projects that use audio from breaking on devices that don't support any audio playback technologies.

Constructor:

new NoAudioSoundManager(game)

Parameters:

name type description
game Phaser.Game

Reference to the current game instance.

Since: 3.0.0
