core-egret.XML

step1. 請建立 game.xml 檔

<?xml version="1.0" encoding="utf-8" ?>
<game>
    <name>Edwin Game</name>
    <stage width="100" height="100"></stage>
</game>

step2. 將 game.xml 拉到資源庫, 請注意文件型態要 Text 而不是 bin

step3. 撰寫程式碼

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 ---

        // game.xml
        `
            <?xml version="1.0" encoding="utf-8" ?>
            <game>
                <name>Edwin Game</name>
                <stage width="100" height="100"></stage>
            </game>
        `;
        // 獲取 xml 字串
        const source = RES.getRes('game_xml');

        // 獲取 egret.XML 物件
        let game: egret.XML = egret.XML.parse(source);
        // nodeType 節點類型，1：XML，2：XMLAttribute，3：XMLText (官方沒有實作 XMLAttribute)
        // 根元素 game 標籤
        egret.log(game.name, game.nodeType); // game 1
        console.log('子元素有:', game.children.length,'個'); // 2

        // 取第 1 個 name 標籤元素
        let gameName: egret.XMLNode = game.children[0]; 
        let nameText: egret.XMLText = gameName.children[0];
        egret.log(gameName.name, gameName.nodeType); // name 1
        egret.log(nameText.nodeType, nameText.text); // 3 "Edwin Game"

        // 取第 2 個 stage 標籤元素
        let gameStage: egret.XMLNode = game.children[1]; 
        egret.log(gameStage.name, gameStage.nodeType); // stage 1
        egret.log(gameStage.attributes); // {width: "100", height: "100"}
        // xml 讀進的數值是字串, 請使用 parseInt 或 parseFloat 將自傳轉成數值
        egret.log(parseInt(gameStage.attributes.width), parseInt(gameStage.attributes.height)); // 100 100

    }

}

// 防止報錯
declare namespace egret {
    interface XML{
        children: egret.XMLNode[];
    }
    interface XMLNode {
        name: string;
        children: any[]; 
        attributes: any; // 應為 egret.XMLAttribute 
    }
}
