In Spark, turning on the Loop feature allows you to 1) automatically advance through all overlays on a Layer, and 2) cycle back to the first overlay on that Layer once it's reached the end.
How it Works
1 - Set a timer
First, make sure all overlays in your desired Layer have a Duration set.
Pages without Durations will be skipped when Loop is activated.
2 - Turn Looping on
Click the Loop icon on the far right of the layer. This will activate the functionality and you'll notice the color changes to indicate that it is active.
Notice if you hover over the icon, you'll see a tool tip appear, indicating that the button turns Auto-Advance on. Hovering over elements within Spark will often give you details about their functionality.
3 - Click an overlay to take to air
To start the Layer Looping, click on any of the overlays in that Layer that have an active Duration. Spark will automatically cycle through the overlays in order once their Duration has expired. Because of Layer Logic, Spark knows to automatically animate overelays on the same Layer off before playing out a new one. Once it reaches the far right overlay on the Layer, Spark will loop back to play the first overlay on the far left of the Layer.
If adjacent overlays are of the same Template, they will perform an Update Animation. If they are different Templates, one will animate off before the other is triggered to play. Your overlays will continue to play on-air regardless if you're on On Air Mode or Edit Mode, so feel free to keep tweaking things or build new overlays while your Loop is running.
4 - Closing the loop
There are three ways to turn looping off.
- Click on the active overlay on that Layer. This is the one that has a red outline. The overlay will animate out.
- Click on the Stop button on the left side of the layer to animate out the current overlay and halt the process of the loop.
- Click again on the Loop button on the right side of the layer. You should see the button change back to a neutral color.
This option will keep the current overlay on-air until it completes its duration. It will then animate off but the next overlay will not play automatically.
Looping allows you to take a hands-free approach to your overlays so you can focus your attention elsewhere when you're on air.
