What Is an Event Action?

An event action is a procedure automatically executed in response to a specified event. An event can be initiated by the user or triggered by the application. You can associate an event, such as mouse click, with an action, such as entering a wormhole, jumping to a new scene, or executing an SQL statement.

You define event actions so that the end user can navigate and execute commands in the published world.

Event Types

The following events can be used to trigger actions:

Mouse click
Mouse double-click
Mouse up
Mouse down

There are two categories of actions: navigation and command.
