EditorGUIUtility.GetAttachToPlayerState

参数

返回

IConnectionState 要在 EditorGUI.AttachToPlayerDropdown 或 EditorGUILayout.AttachToPlayerDropdown 中使用的播放器连接非序列化状态。该状态知道当前连接的目标和可用的目标。

描述

此方法生成状态跟踪对象，用于建立和显示编辑器到播放器连接。

此状态和相应的 GUI 方法（EditorGUI.AttachToPlayerDropdown 和 EditorGUILayout.AttachToPlayerDropdown）应该在 EditorWindow 中使用。提供的编辑器窗口用于： 1.连接时显示覆盖面板 2.建立连接后重新绘制窗口 3.当使用相同连接类型的其他窗口建立连接时，通过 connectedCallback 接收回调调用 从技术上讲，有可能将 parentWindow 作为 null 提供并在 EditorWindow 之外进行使用，但不推荐这样做，而且我们也不计划支持这种用法。

另外切记，收到的状态不是序列化的，需要处理。推荐的使用模式是获取 EditorWindow 的 OnEnable 中的状态，并在 OnDisable 中对其进行处理。

如果通过自动建立性能分析器与播放器的连接或者回退到与编辑器的连接来建立连接，则不会触发 connectedCallback。相反，只会响应主动选择目标的用户，并等待直到建立该连接。如果连接类型是在编辑器窗口之间共享的类型，那么当用户在另一个 EditorWindow 中进行选择时，也会被触发。

返回的状态知道当前连接的目标和可用的目标。
