'PlayerControls.photonView'由于其保护级别而无法访问

Question

需要解决什么？我在浪费时间寻找错误，但都失败了，我该怎么办？

错误：Assets \ MapController.cs（54,31）：错误CS0122：由于其保护级别，无法访问'PlayerControls.photonView'

Answer 1

在PlayerControls.cs中，将private PhotonView photonView;更改为public PhotonView photonView;。

此问题是属性声明中使用的private关键字。这将不允许您访问photonView类之外的PlayerControls.cs属性。将其声明为public可解决此问题。

Answer 2

PhotonView是该类的一个属性，它被声明为protected或private。

如果处理代码，则需要将其声明为公共。如果没有，那么您需要找到某种其他方式来访问它。
