game-egret.URLLoader

egret.URLLoader 使用範例

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();

        // egret 的資源讀取方法
        // 1. egret.HttpRequest 為 xhr 的包裝類
        // 2. egret.ImageLoader 為圖片讀取類
        // 3. egret.URLLoader 為 egret.HttpRequest 的包裝類
        // 4. RES.getRes 筆者推薦使用

        const loader = new egret.URLLoader;
        loader.dataFormat = egret.URLLoaderDataFormat.TEXTURE; // 材質
        loader.addEventListener(egret.Event.COMPLETE, (e: egret.Event) => {
            var texture = e.target.data as egret.Texture;
            this.addChild(new eui.Image(texture));
        }, this);
        loader.load(new egret.URLRequest("resource/assets/Slider/thumb.png"));

        const loader2 = new egret.URLLoader;
        loader2.dataFormat = egret.URLLoaderDataFormat.TEXT; // 文本
        loader2.addEventListener(egret.Event.COMPLETE, (e: egret.Event) => {
            var text: string = e.target.data;
            (this.addChild(new eui.Label) as eui.Label).text = text;
        }, this);
        loader2.load(new egret.URLRequest("resource/config/description.json"));

        const loader3 = new egret.URLLoader;
        loader3.dataFormat = egret.URLLoaderDataFormat.SOUND; // 音樂
        loader3.addEventListener(egret.Event.COMPLETE, (e: egret.Event) => {
            var snd = e.target.data as egret.Sound;
            snd.play(); // 瀏覽器限制, 播放前請至少點擊一次遊戲畫面此方法才能生效
        }, this);
        loader3.load(new egret.URLRequest("resource/assets/bg.mp3"));

    }
