AttributeSetDouble Function

Action

Assigns a floating-point value to a specified attribute of the user. The function automatically creates the attribute if it does not exist.

User attributes are useful when working with Silk Performer frameworks, in fact, when the user behavior is defined in two separate script. In that case, user attributes enable the exchange of data between scripts, for example, between a Silk Performer and a Java script.
