core-egret.ImageLoader

egret.ImageLoader 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();
        // --- Edwin 給你最乾淨的程式碼, 從這行以下開始寫喔 ---

        // 方法1
        const imageLoader = new egret.ImageLoader;
        imageLoader.crossOrigin = 'anonymous'; // 啟用跨域資源共享
        imageLoader.addEventListener(egret.Event.COMPLETE, (e) => {
            const texture = new egret.Texture();
            texture.bitmapData = e.currentTarget.data;
            this.addChild(new eui.Image(texture));
        }, this);
        imageLoader.load('https://www.google.com/pathToImage.png');
        
        // 方法2,請用此方法取代上述方法,更為簡單
        egret.ImageLoader.crossOrigin = 'anonymous'; // 全域參數啟用跨域資源共享
        const tex = await RES.getResByUrl('https://www.google.com/pathToImage.png');
        this.addChild(new eui.Image(tex));

    }
