我正在一个项目中担任实习生，该项目是一对一比例的荷兰城市：格罗宁根。
我的工作是制作（迷你）地图，所以我就这么做了。只有一个问题。在生成时，玩家和小地图的位置是对齐的，但距离生成点越远，这种对齐就越不准确。我希望有人可以帮助我并看看我做错了什么，因为我被困住了！ 这是整个 miniMapManager。看着那（这 double[] 翻译坐标()

如你所见，我计算了 m 的 x/z 位置，并据此给出了纬度/经度，但有些地方出了问题。
这是一个疯狂的猜测，但您是否尝试过使用
double当前您正在使用
Mathffloat=> 可能会到处引入舍入问题，这种比例的 GPS 坐标和纬度/经度需要很高的精度！
如果你查看Mathf的源代码，它主要使用
System.MathfloatSystem.MathRadToDegreedoublepublic const double Deg2Rad = Math.PI * 2.0 / 360.0;
public const double Rad2Deg = 1.0 / Deg2Rad;
等等
