public static Networking.PlayerConnection.IConnectionState GetConnectionState (EditorWindow parentWindow, Action<string> connectedCallback);

파라미터

parentWindow The EditorWindow that will use the connection.
connectedCallback A callback that is fired whenever a user-initiated connection-attempt succeeds.

반환

IConnectionState Returns the unserialized state of the connection to a Player, which is used in PlayerConnectionGUI.ConnectionTargetSelectionDropdown or PlayerConnectionGUILayout.ConnectionTargetSelectionDropdown. The returned connection state object contains information on what target is connected to the Player, and what targets are available.

설명

This method generates a state tracking object for establishing and displaying an Editor to Player Connection.

This state and the corresponding GUI Methods (PlayerConnectionGUI.ConnectionTargetSelectionDropdown and PlayerConnectionGUILayout.ConnectionTargetSelectionDropdown) are supposed to be used from within an EditorWindow. The supplied Editor Window is used to: 1. Display an overlay while connecting 2. Repaint the window after a connection has been established 3. Receive callback calls through connectedCallback when other windows using the same connection type establish a connection Technically, it might be possible to supply parentWindow as null and use it outside of EditorWindow, but that is neither recommended nor a use-case we plan to support.

Also keep in mind that the received state is not serialized and needs to be disposed. The recommended use pattern is to get the state in the EditorWindow's OnEnable and to dispose of it in OnDisable.

The connectedCallback will not be fired if, for example, the connection was made by automatically establishing a profiler connection to a Player or falling back on to the connection to the Editor. Instead, it only responds to a user actively choosing a target, and waits until that connection has been established. If the connection type is one that is shared across Editor windows, it will also be fired when the user chooses it in a different EditorWindow.

The returned state knows what target is currently connected and what targets are available.
