Using Global Parameters in Event Actions You can use global parameters when you create event actions. Suppose you have a scene that contains a pie chart to show the percentages of sales per customer. You might want to allow users to click on a wedge and jump to another scene that shows more details about the wedge. You can use global parameters when you define the event action in the Object Behavior dialog box. Here is an example of how you might do that. To set global parameters in an event action on a Wedge object:
