Triggers

Triggers are key components within interactions, determining when an interaction should activate. Each interaction can contain one or multiple triggers.

Available triggers:

Trigger	Description
On load	Activates upon project loading.
On update	Activates continuously with each frame rendered.
On click	Activates upon a click event.
Mouse enter	Activates when the mouse cursor enters an area.
Mouse exit	Activates when the mouse cursor leaves an area.
Event listener	Activates in response to specific events. Learn more: Events (for API)
While dragging	Continuously activates during cursor drag actions. Note: this trigger only detects the cursor interaction - it does not move the object itself. To physically move an object, use the Transformation action and set the target to Pointer.
While hovering	Continuously activates when the cursor hovers over an area.
WebXR (Enter/Exit)	Activates upon entering or exiting a WebXR session

Triggers can be applied to any 3D object, UI element, or selection within the project.

Trigger type	Description	Target
Object	Select any 3D or 2D object as a trigger. Additional options: Anywhere and Background.	- Anywhere - Background - Group - 3D objects - 2D objects - Hotspots - Clipping plane - Modifiers - Deformers - 3D text
