The Set Data Event.
This event is dispatched by a Data Manager when a new item is added to the data store.
Game Objects with data enabled have an instance of a Data Manager under the
data property. So, to listen for
the addition of a new data item on a Game Object you would use:
A reference to the object that owns the instance of the Data Manager responsible for this event.
The unique key of the data item within the Data Manager.
The item that was added to the Data Manager. This can be of any data type, i.e. a string, boolean, number, object or instance.
