### Implement Map Movement Animation in Android

Source: https://developer.fengmap.com/develop-android-guide-animation.html

This example demonstrates how to create and manage a map movement animation. It shows how to get or create an animation object, set an interpolator (e.g., FMBounceInterpolator), duration, and animation listener. The listener handles animation updates, including moving the map between coordinates and updating the map view. It also shows how to destroy the animation object after use.

```Java
FMValueAnimation va = FMAnimationFactory.getFactory().getFMValueAnimation("AnimationName");
if (va == null) {
    // 若缓存里面不存在创建新的对象
    va = FMAnimationFactory.getFactory().createFMValueAnimation("AnimationName");
    // 设置插值为 
    va.setInterpolator(new FMBounceInterpolator());
    // 设置动画的持续时间
    va.setDuration(1000);
    // 设置动画的监听接口
    va.setOnFMAnimationListener(new FMAnimation.OnFMAnimationListener() {
        @Override
        public void beforeAnimation(String pName) {
            // 动画开始前
        }

        @Override
        public void updateAnimationFrame(String pName, Object pLastValue, Object pCurrentValue) {
            // 动画更新

            FMMapCoord from = (FMMapCoord) pLastValue;
            FMMapCoord to   = (FMMapCoord) pCurrentValue;

            // 不使用方法内置动画
            mMap.move(from, to, false);

            // 更新
            mMap.updateMap();
        }

        @Override
        public void afterAnimation(String pName) {
            // 动画结束后
            // 可以选择销毁对象
            FMAnimationFactory.getFactory().destroyFMValueAnimation(pName);
        }
    });
}
// 设置开始位置和结束位置
va.ofPosition(start, end);
// 开始动画
va.start();
```

### Start Navigation Analysis (Objective-C)

Source: https://developer.fengmap.com/develop-ios-guide-routenavi.html

Initiate navigation analysis, distinguishing between simulated and actual navigation. For simulated navigation, use `simulateWithSpeed:`, `pause`, `resume`, and `stop`. For actual navigation, use `locate:angle:` with real-time positioning data. Actual navigation optimizes position and provides feedback via callbacks.

```Objective-C
//Start simulated navigation, and set the simulated navigation speed, speed range is 0.4-5.0, unit is meters/second
[_navigation simulateWithSpeed:1.0];
//Pause simulated navigation
//[_navigation pause];
//Resume simulated navigation from pause state, this method must be called to resume from pause state
//[_navigation resume];
//Stop simulated navigation
//[_navigation stop];

//Actual navigation is a navigation tool class used when connecting to a real positioning system. This tool class can perform path constraint optimization on the positioning location,
//correct the positioning point to the drawn path, and return navigation results in callback events: corrected coordinates, remaining distance, angle value
//and text description of the corresponding road section.
//The angle is the angle parameter passed when calling - (BOOL)locate: (FMKGeoCoord)position angle: (CGFloat)angle.
//Actual navigation does not process the angle in any way.
//The angle for correcting the positioning coordinates is the angle passed back by the positioning system, and the internal angle is not processed.

 //[_navigation locate:FMKGeoCoordMake(groupID, position) angle:0];
//Each call to this method returns true if navigation analysis is successful, and triggers the navigation callback method.
```

--------------------------------

  - **changeTiltAngle** (boolean) - Optional - Whether to change the map's tilt angle and animate it when the floor changes during real navigation. Defaults to true.
  - **zoom** (number) - Optional - The map's display zoom level at the start of real navigation. Defaults to 21 (scale 1:282).
  - **maxZoom** (number) - Optional - The maximum display zoom level at the start of real navigation. Defaults to 22 (scale 1:141). Prevents the view from becoming too close.
  - **maxOffsetDis** (number) - Optional - Maximum offset distance for the path, in meters. Defaults to 10 meters.
  - **completeDistance** (number) - Optional - The distance threshold for determining navigation completion, in meters. Defaults to 0 meters from the destination.
  - **screenPosition** (object) - Optional - The screen position ratio of the positioning point, e.g., {x:0.5, y:0.75}. During navigation, the positioning point is at the horizontal center and 3/4 vertical position of the screen. Defaults to the center.

### Add Start and End Markers on Fengmap

Source: https://developer.fengmap.com/develop-js.html

Adds image markers to represent the start and end points of a route on the map. It retrieves the appropriate layer and creates an FMImageMarker with a specified URL and size.

```javascript
//添加起点终点marker
function addMarker(coord, type) {
    //获取目标点层
    var group = map.getFMGroup(coord.groupID);
    //创建marker，返回当前层中第一个imageMarkerLayer,如果没有，则自动创建
    var layer = group.getOrCreateLayer('imageMarker');
    var markerUrl = '';
    if (type === 'start') {
        markerUrl = 'images/start.png';
    } else {
        markerUrl = 'images/end.png';
    }
    //图标标注对象，默认位置为该楼层中心点
    var im = new fengmap.FMImageMarker({
        x: coord.x,
        y: coord.y,
        //设置图片路径
        url: markerUrl,
