Ⓒegret.lifecycle.LifecycleContext 用法

LifecycleContext 示例

protected createChildren(): void {
    super.createChildren();

    console.log('egret.lifecycle.contexts.length', egret.lifecycle.contexts.length); // 1, 系統預設有一個 LifecycleContext

    egret.lifecycle.addLifecycleListener((context: egret.lifecycle.LifecycleContext) => {
        // custom lifecycle plugin
        window.onblur = () => context.pause(); // 滑鼠點擊示窗外
        window.onfocus = () => context.resume(); // 滑鼠點擊示窗內
    })

    console.log('egret.lifecycle.contexts.length', egret.lifecycle.contexts.length); // 2, addLifecycleListener 會新增一個 LifecycleContext 用以設置客製化內容

    // 設置心跳開關        
    egret.lifecycle.onPause = () => egret.ticker.pause();
    egret.lifecycle.onResume = () => egret.ticker.resume();

    // 動畫, 受 egret.ticker 影響
    let s = new egret.Shape();
    s.graphics.beginFill(0xFF0000);
    s.graphics.drawRect(0, 0, 100, 100);
    s.graphics.endFill();
    this.addChild(s);
    egret.Tween.get(s, { loop: true }).set({ x: 0 }).to({ x: 200 }, 1000);
}
