SceneNode \ Hover
These events fire when a user points at or moves away from a scene object in VR (without grabbing it). Use them to react as an object is hovered — for example to highlight it, show a label, or hide that hint again when the user looks elsewhere. Each event also tells you which user did it.
Hover events
Node Hover Started
Reacts the moment a user begins pointing at (hovering over) a chosen object in your scene.
What it does
This event fires the instant a user’s pointer or gaze starts resting on the object you connect to it — for example when someone aims their VR controller at a machine part or moves their cursor onto it. It fires once at the start of each hover; it does not keep firing while the pointer stays on the object.
When it fires, it hands you the object that was hovered and the user who started the hover, so you can light up the object, show a label, or play a sound. It only watches for hovers while its Enable input is true, and it never changes the object itself.
Inputs
| Port | Type | What to connect |
|---|---|---|
| Enable | True / false | While this is true the event is active and watches for hovers; set it to false to switch the event off. Defaults to true, so you can leave it unconnected to keep it always on. |
| SceneNode | Scene node | The object in your scene you want to watch. The event fires when a user starts hovering over this object. (A viewer start position cannot be used here.) |
Outputs
| Port | Type | What you get |
|---|---|---|
| Execute | Trigger | Fires when a user starts hovering over the object. Wire this to whatever should happen next, such as highlighting the object or showing a tooltip. |
| SceneNode | Scene node | The object that was hovered over. Handy when one event watches several objects and you want to know which one was pointed at. |
| User | User | The user who started the hover. Useful in shared sessions where more than one person can point at objects. |
Example
| Enable input | true |
| SceneNode input | The Control Panel Button object |
| Execute output | Fires the moment the user aims at the button |
| SceneNode output | The Control Panel Button object |
| User output | The user who pointed at it, e.g. Trainee 1 |
Tips
- Pair this with a “Node Hover Ended” event to turn a highlight on when the hover starts and off again when it stops.
- Set Enable to false to pause the hover reaction during parts of your scene where it should be ignored.
Node Hover Ended
Reacts the moment a user stops pointing at (or looking at) a particular object in your scene.
What it does
This node watches one object you choose. While it is switched on, it fires the instant a user’s hover leaves that object — for example when they move their controller, gaze, or cursor away from it after hovering over it. It’s the natural partner to a hover-start event, letting you undo a highlight, hide a tooltip, or reset an object once the user looks elsewhere.
Each time it fires, it hands you the object the user stopped hovering over and the user who did it, so you can respond to exactly the right thing. It only watches and reports — it doesn’t change the object in any way.
Inputs
| Port | Type | What to connect |
|---|---|---|
| Enable | True / false | While this is true the event is active and watching. Set it to false to switch the event off so it stops firing. |
| SceneNode | Scene node | The object in your scene to watch. The event fires when a user stops hovering over this object. (The viewer start position cannot be used here.) |
Outputs
| Port | Type | What you get |
|---|---|---|
| Execute | Trigger | Fires when the user stops hovering over the chosen object. Wire this to whatever should happen next. |
| SceneNode | Scene node | The object the user stopped hovering over — handy when you want to act on that same object. |
| User | User | The user whose hover just left the object. Useful in shared sessions to tell who did it. |
Example
| Enable input | true |
| SceneNode input | The Control Panel Button object in your scene |
| Execute output | Fires when the user moves their pointer off the button — wire it to a node that removes the button’s highlight |
| SceneNode output | Control Panel Button |
| User output | The user who was hovering, e.g. Trainee 1 |
Tips
- Pair this with a hover-start event on the same object: start the highlight when hovering begins, and use this node to remove it when hovering ends.
- To stop watching at any time, feed a false value into Enable — the event will go quiet until you switch it back on.
