Listener Reference

Generated reference pages for GDLink listener bricks.

Brick	Purpose	Tier
Always	The Always listener continuously outputs a positive pulse every tick, providing a constant activation signal for testing and basic logic flows.	Basic
Delay	Waits a specified number of ticks before activating, optionally staying active for a duration, with optional repeating.	Basic
Keyboard	Detects keyboard input with trigger modes, pulse detection, modifier key requirements, and inversion.	Basic
Mouse	Detects mouse buttons, movement, wheel, and hover events.	Basic
Cursor	Publishes current cursor screen coordinates into GDLink variables and triggers graph flow from cursor presence or movement.	Basic
Gamepad	Detects gamepad input across buttons, D-Pad directions, analog stick axes, and analog triggers.	Basic
Touch	Detects touch input on mobile devices and touchscreens.	Basic
UI Hover	Detects when the mouse cursor hovers over UI elements (Control nodes).	Basic
UI Click	Detects mouse button clicks on UI elements (Control nodes).	Basic
Collision	Detects collisions and overlaps with other physics objects, with filtering by name, group, material, or property.	Basic
Ray	Casts a ray from the object in a specified direction and triggers when the ray hits something, with optional filtering.	Basic
Near	Detects when objects enter or exit a spherical (3D) or circular (2D) radius around the listener’s parent object.	Basic
Radar	Detects objects within a cone-shaped field of view (FOV), like a radar or vision cone.	Basic
Transform	Monitors transform changes on a Node2D or Node3D target and fires when the sampled position, rotation, or scale delta matches the configured threshold/mode.	Basic
Movement	Detects when an object is moving, stopped, accelerating, or changing direction.	Basic
Gravity	Detects the current gravity state of the object, enabling logic to react to changes in gravity such as zero-G animations, wall-walking controls, or gravity well effects.	Basic
Variable	Monitors Global or Local variables and triggers when a comparison condition is met.	Basic
Random	Triggers randomly based on a probability percentage, useful for creating unpredictable behaviors and variations.	Basic
Inventory	Fires reactive events when the inventory state changes or when a player interacts with a slot.	Basic
Message	Listens for messages sent via Message Executor on a specific subject/channel, enabling object-to-object communication.	Basic
Signal	Detects when a specific Godot signal is emitted by a target node.	Basic
XR Input	Unified controller input listener for all XR devices (Quest, Vive, Index, etc.).	Pro
XR Tracking	Unified tracking data listener that senses spatial/skeletal/biometric state from XR trackers.	Pro
XR Ray	Spatial raycasting from XR controller or HMD for pointer interactions and teleport target identification.	Pro
