2.5.7 实时路径漫游

实时路径漫游

实时路径漫游是动态路径漫游的一种模式。它可以在播放的过程中删除关键点列表前端的点以及在列表的后端追加关键点，但不影响路径的播放。

由于是实时路径漫游是属于动态路径漫游中的一种，对于图层的创建以及编辑，可以参考动态路径漫游，这里只介绍实时路径漫游特有的一些操作。实时路径漫游主要包括以下几种特有的操作。

创建图层。这与动态路径漫游的创建大体相同，只是在设置播放模式时，PlayerMode 必须设为PLAYER_ONEWAY_STAY。即实时播放。
改变关键点容量。通过更新KeyPointCapacity参数可设置最大存储关键点数量，默认为-1，代表不限容量。当设定一个容量时，如果关键点数量超出该容量，在播放的过程中，会自动剔除已经播放的关键点。
剔除关键点。在播放的过程中，也可以手动剔除已经播放的关键点。通过更新图层操作将OperationName参数设为 PopKeyPoint，然后设置PopSize 参数的数量，可以删除已经播放的关键点个数。
追加关键点。可以在关键点末尾进行关键点的追加。通过更新图层操作将OperationName参数设为 AppendKeyPoints，然后在KeyPoints 参数中设置追加的关键点集，即可实现关键点的追加。

实时路径漫游主要用于模拟GPS实时跟踪效果模拟。在播放的过程中，定时接收GPS传递的关键点信息，然后通过追加关键点操作让路径一直延伸。

注意： 如果关键点都已经播放完毕，在进行追加关键点操作之前，路径会暂停等待，直到有新的关键点追加进来，路径才会继续播放。

下图是开启实时路径播放的效果：
