android - Nutiteq 3D 和 OpenStreetMaps 中的随机标记和动画

Question

我要为 Android 平台开发一款基于位置的游戏。我想在随机坐标(用户位置周围)但在路上创建一个标记!此外，我将从这一点 (A) 到第二个随机点 (B) 为该标记制作动画。有什么想法吗？

谢谢!

ps.我用的是Nutiteq 3D map app的示例代码

}

ps.This is excactly i wand to do but in android sdk http://openplans.github.io/Leaflet.AnimatedMarker/

Answer 1

您可以只使用 Nutiteq SDK 中标记的 setMapPos() 方法。
