PlayerConnectionGUI.ConnectionTargetSelectionDropdown

参数

描述

显示一个下拉按钮和菜单，供用户选择并建立与玩家的连接。

此控件与 性能分析器窗口、帧调试器 或 控制台窗口 的工具栏中使用的控件相同。下拉菜单将列出您的编辑器可以连接到且可发现的所有可用玩家和编辑器。它还提供了一个直接连接到 IP 地址的条目。您需要提供用于 编辑器窗口 的连接状态。要获取一个，请在 OnEnable 中使用 PlayerConnectionGUIUtility.GetConnectionState，并在您使用的 编辑器窗口 的 OnDisable 中记得释放状态。

此类目前仅适用于性能分析工具和控制台使用的连接。在将来的版本中，这将与 PlayerConnection 一起使用。

            case ConnectionTarget.Editor:
                // The name of the Editor or the PlayMode Player would be "Editor" so adding the connectionName here would not add anything.
                Profiler.enabled = GUILayout.Toggle(Profiler.enabled, "Profile the Player in the Editor", EditorStyles.toolbarButton);
