[LayaAirIDE 2.0]微信小游戏，实现监听前后台切换

一个简单的思路，不知道Laya本身是否有解决方案啊
wxhelper.js

class WXHELPER {

    constructor () {

        this._isWxContext = !!window.wx

    }



    onShow (callback) {

        if (!this._isWxContext) return

        window.wx.onShow(callback)

    }



    onHide (callback) {

        if (!this._isWxContext) return

        window.wx.onHide(callback)

    }



    offShow (callback) {

        if (!this._isWxContext) return

        window.wx.offShow(callback)

    }



    offHide (callback) {

        if (!this._isWxContext) return

        window.wx.offHide(callback)

    }

}



const wxHelper = new WXHELPER()

export default wxHelper

gameController.js

import wxHelper from 'wxhelper'

export default class welcome extends Laya.Script {

    constructor() {

        super()

    }



    onEnable() {

        wxHelper.onShow(this.resumeGame)

        wxHelper.onHide(this.pauseGame)

    }





    resumeGame () {

        console.log('resumeGame')

    }



    pauseGame () {

        console.log('pauseGame')

    }



    onDestroy () {

        wxHelper.offHide()

        wxHelper.offShow()

    }

}
