Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://help.vectary.com/documentation/3d-configurator/interactions/triggers.md). # 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. `May cause performance issues`
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
Selection	Selections are useful when objects belong to different groups or cannot be placed in a single group. There are two ways to add a selection: 1. If a selection has already been created, simply choose it from the list. 2. Select the required objects (minimum two) on the left panel using `Ctrl` and click the `+` icon. Learn more: Selections
Floating UI	It is possible to select either the entire Floating UI (Parent) or a specific Floating UI element	- Entire Floating UI - Image - Button - Divider - Container - Slider - Input - Variants - Materials

--- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://help.vectary.com/documentation/3d-configurator/interactions/triggers.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
