我对PUN和Unity有些陌生,所以希望我犯了一些初学者的错误。
void Update(){
if(launch == true){
Debug.Log("launched");
myPhotonView.RPC("ChangeScene", PhotonTargets.All);
}
//myPhotonView.RPC("ChangeScene", PhotonTargets.All);
}
当我运行上面的代码时,我可以看到在控制台中启动但是我得到了
“NullReferenceException:对象引用未设置为的实例 对象“在这一行:myPhotonView.RPC(”ChangeScene“, PhotonTargets.All);
当我用该行注释掉并且在if语句之外的行取消注释时运行它时,没有空引用异常并且该方法执行。上面的代码中是否有错误,或者这是Photon中的错误?
任何帮助都非常感谢。如果有人认为有必要,我可以发布完整的代码或错误消息。
此外,这不太重要,但myPhotonView在我创建的任何方法中都为null,这些方法不是常规的MonoBehaviour方法,如Start或Update,即使我将其设置为全局变量并在尝试访问它之前将其填入Start 。这似乎可能与我遇到的其他问题有关,这是我为此使用Update的唯一原因。

编辑:我从未设法解决这个问题,但我确实解决了这个问题。我创建了游戏对象,为游戏中的其他玩家提供价值。请告诉我更多信息
