我有一个带有下拉脚本的dropdowncontroller对象，然后我将两个下拉对象拖到脚本中。

包含枚举的GoogleAPi脚本位于rawimage对象中，即地图。没有提及GoogleAPI脚本中的下拉列表。只有枚举。应该有吗？

“缺少程序集引用错误是针对3”_locationSelected.locationSelected = GoogleAPI.Locations.Pentraeth;“ “_locationSelected.locationSelected = GoogleAPI.Locations.Newborough;” “_locationSelected.locationSelected = GoogleAPI.Locations.Another;”

这个想法将是2个开关案例。 1检查Locationsdropdown值，然后更改具有变量locationSelected的Locations枚举的状态，然后更改lat和lon坐标，然后生成新地图。

另一个开关案例应该完全相同的逻辑，但改变maptype而不是lat和lon。

我把开关盒放在try中，因此我可以得到一些debug.logs，这是正确的吗？

认为我已经足够清楚了！

Answer 1

错误似乎很清楚。您需要在引用googleapi的文档顶部添加using语句。

Answer 2

修正了它。猜猜这是一个错误，因为Unity和Visual Studio只需要重启。现在错误消失了。

所以如果有人得到'错误CS1061：你错过了程序集引用吗？'一切看起来还不错。刚刚重启。为我工作，我看到了另一个线程，它也为他们工作。

通过更改脚本2中的下拉值来更改脚本1中的枚举状态。“您是否缺少程序集引用？”
