Detailed Description

interface for saving changable data of an action

Since the "Id" of an action is the pointer itself, and this pointer is used in every action set, we can't set the changeable data of an action that easily, since it would change the action's data everywhere in the program. If this isn't wanted (as usual), we have to use action data objects. New action data objects can be retrieved from any action class (if there is no changeable data for an action the action will return a NULL pointer). This action data object is now local, and not global any more and can therefore be changed easily. If an action has changeable data, the action pointer and a coresponding action data object determine the action. This is used in many function-arguments. Normally, if the action-data object is missing (= NULL) a new action data object is retrieved from the action.

At the momemt its used for saving the data of MultiStepActions (duration, finished), and ContinousActions (saving the continuous action value) all other classes return NULL when asking them for a CActionData Object.
