PlayerConnectionGUILayout.ConnectionTargetSelectionDropdown

参数

描述

展示一个下拉按钮和菜单，供用户选择并建立与播放器的连接。

这是与 Profiler Window、Frame Debugger 或 Console Window 工具栏中使用的控件相同的控件。下拉选项会列出所有可用的播放器和编辑器，供你的编辑器连接且可发现。它还提供了直接连接到 IP 地址的条目。你需要为你 EditorWindow 提供连接状态。若要获取状态，请在 OnEnable 中使用 PlayerConnectionGUIUtility.GetConnectionState。确保在你使用的 EditorWindow 的 OnDisable 中释放状态，以免发生泄漏。

目前，此类仅适用于配置文件工具和控制台使用的连接。在未来版本中，这将适用于 PlayerConnection。

public class MyWindow : EditorWindow
{
    // The state can survive for the life time of the EditorWindow so it's best to store it here and just renew/dispose of it in OnEnable and OnDisable, rather than fetching repeatedly it in OnGUI.

    }

    private void OnEnable()
    {
        // The state of the connection is not getting serialized and needs to be disposed of.
        // Therefore, it's recommended to fetch it in OnEnable and call Dispose() on it in OnDisable.
        attachProfilerState = PlayerConnectionGUIUtility.GetConnectionState(this, OnConnected);
    }

    private void OnConnected(string player)
    {

            case ConnectionTarget.None:
                //This case can never happen within the Editor, since the Editor will always fall back onto a connection to itself.
                break;
            case ConnectionTarget.Player:
                Profiler.enabled = GUILayout.Toggle(Profiler.enabled, string.Format("Profile the attached Player ({0})", attachProfilerState.connectionName), EditorStyles.toolbarButton);
                break;
            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);
                break;
            default:
                break;
        }
        EditorGUILayout.EndHorizontal();

    private void OnDisable()
    {
        // Remember to always dispose of the state!
        attachProfilerState.Dispose();
    }
