当玩家进入房间时执行操作

Question

我想使用 Photon (Pun2) 创建一个多人游戏应用程序。玩家加入房间后，我想为该房间中的所有玩家隐藏一些按钮并显示其他按钮。目前我有这个功能：

public override void OnPlayerEnteredRoom(Player newPlayer)
     {
         print(newPlayer); // #02
         if (PhotonNetwork.CurrentRoom.PlayerCount == 2 && PhotonNetwork.IsMasterClient)
         {
             print(PhotonNetwork.CurrentRoom.PlayerCount + "/2 Starting game...");
 
             searchingBtn.SetActive(false); // hide this button
             findMatchBtn.SetActive(false); // hide this button
             scanningBtn.SetActive(true); // display this button
         }
     }

但这不起作用，因为只有 2 名玩家中的 1 名按钮会改变，而另一名玩家的按钮将保持不变。

我在网上看到一些例子，在这个函数OnPlayerEnteredRoom里面叫PhotonNetwork.LoadLevel(scene_index)，但是那一刻，我不想加载另一个场景，我想留在当前场景中，只是隐藏/显示一些按钮。这甚至可能吗？

编辑：这是最终版本

public override void OnJoinedRoom()
{
    Debug.Log("You joined the room.");
    Debug.Log(PhotonNetwork.CurrentRoom.PlayerCount);
    Debug.Log(PhotonNetwork.IsMasterClient);

    UpdateButtons();
}

public override void OnPlayerEnteredRoom(Player newPlayer)
{
    Debug.Log("Other players joined the room.");
    if (PhotonNetwork.CurrentRoom.PlayerCount > 1 && PhotonNetwork.IsMasterClient)
    {
        Debug.Log(PhotonNetwork.CurrentRoom.PlayerCount + "/2 Starting game...");

        UpdateButtons();
    }
}

private void UpdateButtons()
{
    searchingBtn.SetActive(false); // hide this button
    findMatchBtn.SetActive(false); // hide this button
    scanningBtn.SetActive(true); // display this button
}

来自光子文档：

virtual void OnJoinedRoom ()
    //Called when the LoadBalancingClient entered a room, no matter if this client 
    //created it or simply joined.

virtual void OnPlayerEnteredRoom (Player newPlayer)
    //Called when a remote player entered the room. This Player is already added to 
    //the playerlist.

有了这些知识，OnPlayerEnteredRoom 只会在远程玩家加入房间时被调用。因此，为了解决您的问题，您需要在本地客户端的OnJoinedRoom 回调中调用您的代码，并在远程玩家加入时调用OnPlayerEnteredRoom。

总而言之，您的新代码应如下所示：

public override void OnPlayerEnteredRoom(Player newPlayer)
{
     UpdateButtons(newPlayer);
}

public override void OnJoinedRoom(Player player)
{
    UpdateButtons(player);
}

private void UpdateButtons(Player player)
{
    if (PhotonNetwork.CurrentRoom.PlayerCount > 1 && PhotonNetwork.IsMasterClient)
    {             
        print(PhotonNetwork.CurrentRoom.PlayerCount + "/2 Starting game...");
 
        searchingBtn.SetActive(false); // hide this button
        findMatchBtn.SetActive(false); // hide this button
        scanningBtn.SetActive(true); // display this button
    }
}
