The Watch watches for changes in an Attribute and triggers if the attribute changes via the Change Value action. Watch trigger is unaffected by changes to attribute via API Method.
The Author can decide what kind of change to watch for – an increment, decrement or either.
NOTE: the watch trigger compares previous value with new value:
- If old value > new then Watch fires on
- If old value < new then Watch fires on
- If old value is different from new value (larger or smaller) then Watch fires on Changed.
In the Beat Sheet below, the Watch trigger watches the Project-level Attribute “Game_On”. When Game_On is set to True, the beat Game On activates and Conducttr posts to Tumblr the post “The Game is now in progress!”
