No problem on android phone but no sound can be heard in wechat on iphone. (Audio auto-play problem of WeChat browser in ios environment)
Solution:
<script>
function playsound(sound, loop) {
if (sound == null) {
console.log('sound err')
return;
}
var times = loop ? 0 : 1;
if (typeof WeixinJSBridge != 'undefined') {
WeixinJSBridge.invoke('getNetworkType', {}, function (e) {
return sound.play(0, times).volume = 0;
});
} else {
return sound.play(0, times).volume = 0;
}
}
</script>
Next, how do we call it in ts?
class SoundManager {
private static _instance: SoundManager;
private onOff: boolean = true;//Sound effect master switch
private music: MusicPlay;//background music
public static get instance() {
if (!this._instance) {
this._instance = new SoundManager();
}
return this._instance;
}
/**
* play music
*/
public playMusic(pKey: string = "", volume = 0.5) {
}
//stop playing music
public stopMusic() {
}
//Constructor
public constructor() {
this.music = new MusicPlay();
}
//Play background music that can be controlled after mute boot
//This method is best executed when loading is finished, and it is easy to use before all music is played.
public playNullSound() {
//First load the music resources and get the music resources before calling the methods in index.html,
I load it in advance when loading, so I get resources synchronously
let nullSound: egret.Sound=RES.getRes("nullSound_mp3");
window["playsound"](nullSound, false);
}
}
//The sound resource is loaded, the playback is muted, and the background music that can be controlled is played after the mute guide
SoundManager.instance.playNullSound();
