Events
Events are at the core of interactive experiences. They define what should happen at a certain point in time, or when the user interacts with an Interactive Element.
Interactions
By clicking on an Interactive Element, you will be able to display its properties inside of the Properties View. Here are the interactions which you can detect on an Interactive Element and which you can associate with an Action.
| Name | Description | Note |
|---|---|---|
| Select | Corresponds to a more general interaction to select a button. Tip: This is generally the interaction you want to use. It combines Gaze for seconds, Gaze and tap and Touch on Cardboard. | |
| Gaze in | The Event is triggered as soon as the user starts looking at an Interactive Element. |
|
| Gaze out | The Event is triggered when the user looks away from an Interactive Element he was looking at. |
|
| Gaze for seconds | The Event is triggered when the user maintains a gaze at an Interactive Element for a certain amount of time. |
|
| Gaze and tap | The Event is triggered when the user is gazing at an Interactive Element and then taps taps the Gear VR's touchpad. | |
| Touch | Corresponds to a touch on an Interactive Element on a touchscreen. Works on Cardboard 2D mode, like in a standard mobile app. | |
Time Events
You can let something happen a certain amount of time after a Node started (Node Event in the Node properties) or after an experience started (Experience event in experience properties). In both cases, you need to fill in the property Time (in seconds), which is the time at which the Event should happen.
Action
This defines what happens during an Interaction or Timer Event.
You will be able to select an Interactive Element among the ones in the node.
