Rules are one of the most powerful features in PADS4. They let a presentation, page, or page element respond automatically when a predefined situation occurs during playback.
How a rule works
Every rule has two parts:
- Condition (IF) — the situation that PADS4 watches for.
- Action (THEN) — what PADS4 does when that condition is met.
When the condition is true during playback, the action runs.
Where you can define rules
Rules can be set at three levels:
- Presentation level — affect the entire presentation.
- Page level — affect a single page.
- Page element level — affect an individual element on a page.
You can create as many rules as you need at each level, but only one rule of the same type can be active at any given time.
Most rules are linked to a data provider so they can react to real-time data events.
Examples
Presentation rule
- If no real-time data is available, switch to an advertising page. When data becomes available again, switch back to the original page.
Page rule
- If the current time is between 10:00 AM and 11:00 AM, hide the page so it is skipped.
Page element rule
- If a real-time data value rises above a defined threshold, change the element’s background color to red.
