A base class to implement debugger plugins. [EditorDebuggerPlugin] provides functions related to the editor side of the debugger. To interact with the debugger, an instance of this class must be added to the editor via [method EditorPlugin.add_debugger_plugin]. Once added, the [method _setup_session] callback will be called for every [EditorDebuggerSession] available to the plugin, and when new ones are created (the sessions may be inactive during this stage). You can retrieve the available [EditorDebuggerSession]s via [method get_sessions] or get a specific one via [method get_session]. [codeblocks] [gdscript] @tool extends EditorPlugin class ExampleEditorDebugger extends EditorDebuggerPlugin: func _has_capture(prefix): # Return true if you wish to handle message with this prefix. return prefix == "my_plugin" func _capture(message, data, session_id): if message == "my_plugin:ping": get_session(session_id).send_message("my_plugin:echo", data) func _setup_session(session_id): # Add a new tab in the debugger session UI containing a label. var label = Label.new() label.name = "Example plugin" label.text = "Example plugin" var session = get_session(session_id) # Listens to the session started and stopped signals. session.started.connect(func (): print("Session started")) session.stopped.connect(func (): print("Session stopped")) session.add_session_tab(label) var debugger = ExampleEditorDebugger.new() func _enter_tree(): add_debugger_plugin(debugger) func _exit_tree(): remove_debugger_plugin(debugger) [/gdscript] [/codeblocks] Override this method to process incoming messages. The [param session_id] is the ID of the [EditorDebuggerSession] that received the message (which you can retrieve via [method get_session]). Override this method to enable receiving messages from the debugger. If [param capture] is "my_message" then messages starting with "my_message:" will be passes to the [method _capture] method. Override this method to be notified whenever a new [EditorDebuggerSession] is created (the session may be inactive during this stage). Returns the [EditorDebuggerSession] with the given [param id]. Returns an array of [EditorDebuggerSession] currently available to this debugger plugin. [b]Note:[/b] Not sessions in the array may be inactive, check their state via [method EditorDebuggerSession.is_active]
