KmlTourFlyTo

KmlTourFlyTo 是 CesiumJS 中的一个类,用于定义 KML(Keyhole Markup Language)数据中的飞行到动画。它继承自 KmlTourPrimitive 类并添加了目标位置和时间延迟属性。

属性

property stopTime: JulianDate

定位结束时的 Julian 日期。

property position: Cartesian3

定位的目标位置。

property delay: TimeInterval

执行动画前需等待的时间。

方法

function flyTo(duration: number): FlyTo

动画定位到实体的位置并返回 FlyTo 对象以控制动画。

参数 duration 指定动画时长(单位为秒)。

示例

以下示例演示如何使用 KmlTourFlyTo 类:

// 添加 KML 数据源
var dataSource = new Cesium.KmlDataSource();
dataSource.load('myTour.kml');

viewer.dataSources.add(dataSource);

// 等待 3 秒后开始定位到位置
var flyTo = dataSource.entities.getById('myFlyTo').flyTo(5.0);

// 事件到达时触发
flyTo.then(function(){
    console.log('动画完成');
});
