egret.StageOrientationEvent 判斷橫屏幕或豎屏幕範例

class Main extends eui.UILayer {

    protected createChildren(): void {
        super.createChildren();
        egret.lifecycle.onPause = () => egret.ticker.pause();
        egret.lifecycle.onResume = () => egret.ticker.resume();
        egret.registerImplementation('eui.IAssetAdapter', new AssetAdapter());
        egret.registerImplementation('eui.IThemeAdapter', new ThemeAdapter());
        this.runGame();
    }

    private async loadResource() {
        let loadingView = this.stage.addChild(new LoadingUI()) as LoadingUI;
        await RES.loadConfig('resource/default.res.json', 'resource/');
        await new Promise(resolve => new eui.Theme('resource/default.thm.json', this.stage).once(eui.UIEvent.COMPLETE, resolve, this));
        await RES.loadGroup('preload', 0, loadingView);
        this.stage.removeChild(loadingView);
    }

    private async runGame() {
        await this.loadResource();
        // --- Edwin 給你最乾淨的程式碼, 從這行以下開始寫喔 ---

        // 範例 1. 直接程式裡修改旋轉模式
        this.stage.orientation = egret.OrientationMode.AUTO;

        // 範例 2. 另外想判斷橫豎屏幕以下是變通方法
        // 注意, 只有 this.stage 註冊才有效, 不能用 this 或任何非 stage 物件註冊
        this.stage.addEventListener(egret.StageOrientationEvent.ORIENTATION_CHANGE,(e:egret.StageOrientationEvent)=>{
            // 判斷橫屏幕或豎屏幕
            const orientation = window.innerHeight > window.innerWidth ? egret.OrientationMode.PORTRAIT : egret.OrientationMode.LANDSCAPE;
            console.log(orientation); // portrait or landscape
        },this);

    }
