animatorVector事件问题

0 投票
您好:

 我想请问下在animatorVector中,怎样去获取动画在每一帧的时候的事件,我看在js的API上显示的是用drawFrame,但是没有用,有没有其他的方法?

您好,我这边测试了一下这个功能是可以正常实现的,您那边是监听后没有效果吗?

您好

animatorVector.events.on({"drawFrame":drawFrame});

function drawFrame(feature) {
        console.log("test");
        //console.log(feature);
    }

监听后没有任何效果,console.log("test")这段代码都无法执行
您是在咱们官网上看的么?我这边在官网的话是正常的
您好
官网上是这样的例子

{Array(String)} 此类支持的事件类型。

  • drawfeaturestart 每次绘制在当前时间节点内的feature时触发。
  • drawFrame 绘制帧,动画的每一帧都会触发此事件,传回的参数即为当前渲染的要素
  • featurerendered 要素渲染事件,当要素被渲染后发触发,返回一个当前补间动画中真实被渲染的要素,这样可记录运动的轨迹 例如:
//使用下面的方法将图层添加到map
var animatorVector = new SuperMap.Layer.AnimatorVector("animatorVector", {}, {
    //设置速度为每帧播放0.05的数据
    speed:0.05,
    //开始时间为0
    startTime:0,
    //每秒渲染12帧
    frameRate:12,
    //结束时间设置为10
    endTime:10
});
layer.events.on({"drawfeaturestart": drawfeaturestart});


function drawfeaturestart(feature) {

}

但是我把drawfeaturestart": drawfeaturestart换成"drawFrame":drawFrame就无法监听执行

您私信我一个联系方式,然后方便的话我远程看一下您那边的情况
您好

请问方便提供一下你的测试DEMO吗
我这边就是用的官网的执行的
