Inheritance Hierarchy

Area2D is a 2D area node used for collision detection. It extends Node2D and provides area-based collision functionality.

Fields

Area2D has no additional fields beyond those inherited from Node2D.

Signals

Area2D nodes automatically emit signals based on their name field when objects enter, occupy, or exit the area. The signal naming follows a pattern:

• NAME_Entered - Emitted when an object first enters the area
• NAME_Occupied - Emitted while an object is inside the area
• NAME_Exited - Emitted when an object leaves the area

For example, if an Area2D node has name = "Door", it will emit "Door_Entered", "Door_Occupied", and "Door_Exited" signals.

@script DoorHandler extends Node    fn init() {        // Connect to Area2D signals by the area's name        Signal.connect("Door_Entered", on_door_entered)        Signal.connect("Door_Exited", on_door_exited)    }     fn on_door_entered() {        Console.print("Player entered the door area")    }     fn on_door_exited() {        Console.print("Player left the door area")    }

The Area2D node doesn't need any script attached - it automatically emits these signals based on collision detection. Any script can listen for these signals by connecting to the appropriate signal name. See the Signals documentation for more information.

Basic Usage

@script TriggerArea extends Area2D    fn init() {        // Area2D for collision detection        self.name = "Trigger"        // Will emit: Trigger_Entered, Trigger_Occupied, Trigger_Exited    }
