Time Sensors provide a powerful, easy way to set up timed actions and transitions into your VR presentation.
In contrast to Proximity Sensors, which rely on user behavior to trigger actions, Time Sensors trigger actions based on the amount of time that has elapsed once users enter a scene in your Presentation. Here's how to set them up.
You'll find the Time Sensor at the bottom of your Asset Library. Drag it into your scene. You can see the Time Sensor icon in your scene, but when inside a Vizible Session, Time Sensors aren't visible.
To set the amount of time until the Time Sensor gets triggered, right click on the Time Sensor and select "Set Duration". If you want something to happen after 5 seconds, you would set the Duration to 5 seconds. If you want something to happen repeatedly at 5 second intervals, you can select "Set Repeats" and select how many times you'd like the action to repeat. Here I am setting the Duration to 5 seconds. As I only want this action to happen once, I won't set any Repeats:
To set the Action that will happen once the Time Sensor is triggered, right click on the Time Sensor and select "On Trigger" and then select "On Elapsed". The Sensor will turn green, which lets you know that you can set any Actions that will happen once the Sensor is Triggered. You can right click on objects in the scene to add actions to them, and you'll see a preview of the action you set. One Time Sensor can trigger multiple actions. Here I am setting an action that will move an object (the baseball) in my scene:
To return to the regular editing mode, simply right click on the Time Sensor again and select "Exit Active Trigger".
If you want a sequence of actions to unfold at certain times in your Presentation, you can have as many Time Sensors as you want on any particular Slide.
Tip: One of the Actions you can link to Time Sensors (and Proximity Sensors) is a Slide Transition. In other words, if you want your VR Presentation to move along automatically based on time, without any user input, you could set up your Time Sensors to make this happen. Follow steps 1-3 above, but instead of adding an action to the baseball, add a "Set Slide" action to the "Scene" object. You can then set a value for the slide you want the participants to move to once the Time Sensor goes off. Here I am setting up a Time Sensor that will move the Presentation to Slide 3 after the Time Duration has elapsed.
