属性动画

指定相应的动画数据，然后控制物体或者摄像机做一些有规律的动画。 可自定义动画数据，也可以用插件编辑导出。

物体动画 和 摄像机动画

这两种动画的驱动方式是一样的

// 自定义数据动画
protected createObjectAnimation() {
    var cube: egret3d.Mesh = new egret3d.Mesh(new egret3d.CubeGeometry(100, 100, 100));
    cube.material.diffuseTexture = this.queueLoader.getAsset("resource/doc/materail/FLOOR_1.png");
    this.view.addChild3D(cube);

    // 创建一个动画对象
    var proAnim: egret3d.PropertyAnim = new egret3d.PropertyAnim();

    // 指定动画曲线
    var animCurves: egret3d.AnimCurve[] = [];

    var c0: egret3d.AnimCurve = new egret3d.AnimCurve();
    c0.start.x = 0;
    c0.start.y = 0;

    c0.end.x = 3000;
    c0.end.y = 300;

    c0.c1.x = 0;
    c0.c1.y = 0;

    c0.c2.x = 10;
    c0.c2.y = 10;

    var c1: egret3d.AnimCurve = new egret3d.AnimCurve();
    c1.start.x = 3000;
    c1.start.y = 8;

    c1.end.x = 6000;
    c1.end.y = -500;

    c1.c1.x = 30;
    c1.c1.y = 30;

    c1.c2.x = 50;
    c1.c2.y = 10;

    animCurves.push(c0);
    animCurves.push(c1);

    proAnim.addAnimCurve("y", animCurves);

    var proAnimation: egret3d.PropertyAnimController = new egret3d.PropertyAnimController();
    proAnimation.addPropertyAnim(proAnim);
    // 给cube 创建属性动画控制器
    
    cube.proAnimation = proAnimation;

    // 播放
    proAnimation.play();
}

// 导入有动画的场景
protected importObjectAnimationScene() {
    // 特效资源加载完成后，把特效加入场景中
    var scene: egret3d.Scene3D = this.queueLoader.getAsset("resource/doc/animation/MapConfig.json");
    this.view.scene = scene;
    // 找到导出场景中的主摄像机  设置为当前摄像机
    this.view.camera3D = <egret3d.Camera3D>scene.findObject3D("Camera");

    //// 找到场景中的水晶对象 然后播放动画  如果动画没有自动播放需要查找节点proAnimation.play()
    //var Crystal: egret3d.Object3D = scene.findObject3D("Crystal");
    //Crystal.proAnimation.play();
}
