Scene elements – Audio

Sometimes a scene requires a bit more extra media or information. E.g. an audio clip giving instructions to the student, an in-scene video that a student can optionally watch first, or several in-scene text boxes next to objects of interest. This is where scene elements become very helpful. Scene elements are extra elements that can be added to a node. In the app they appear as small round icons with either a default icon or (if set) a custom icon. They are clickable in the app, so depending on the type of the scene element either a text box will show, audio will play or a video frame will show.

Adding an audio scene element

Scene elements can be added to either a 360 Image or Scenario Question node. After clicking on the ‘Scene Elements’ button, a window shows where scene elements can be added to the node. In the type filter we have to select what type of scene element we want to add. In this case an Audio Scene Element. Then we press on the plus button and a new audio scene element is added without yet an audio file assigned to it. With the edit button (pencil) we open the media picker in which we can select an audio file we uploaded earlier with the upload side bar.

Added elements can be deleted with the recycle bin button or previewed with the eye icon. Multiple scene elements can be added to a node and also of mixed type.

Positioning the scene element

After the scene element is added in the node, it still has to be positioned in the scene as well. For this, press ‘Edit Scene’ to see the Scene View and find the scene element in the overview panel on the right. Press the plus button to add it to the scene and then click and drag it into position. There are also some extra properties here. Autoplay means the audio will start to play upon start of the scene in the app. Loop means that the audio will infinitely repeat (or until the student pauses it by clicking on the playing scene element). Hidden means the scene element is initially invisible in the app, so it is not visible but a student can still click on it.

Audio scene element properties

AutoplayThe audio will automatically play at the start of the scene
LoopThe audio will loop continuously (unless playback is halted by pressing its controls)
HiddenThe element icon is initially invisible
Show ControlsPlayback controls are removed. So students can’t interact with playback

Note: when hidden is combined with autoplay, the autoplay will trigger the audio scene element and therefore its icon is no longer hidden.

Setting a custom icon

Scene elements have a default icon representing their type, but this icon can be replaced with a custom icon. Click on the small edit button that appears when you hover over the scene element icon. Now a custom icon can be selected from the element icons uploaded via the side bar. They can also be reverted to the default icon by hovering over the icon and pressing the recycle bin button.
