The classes in the model system are (at least in mid-July 2005), in a vague UML-ish syntax, arranged somewhat like:
Random Actors
Selections are made at three levels:
- Global - e.g. "Winter".
- Entity - e.g. "Chop".
- Actor - e.g. "Helmet B". (The same selections are used for the base actor and all prop actors.)
Global-level selections are currently unimplemented.
Entity-level selections are set by CUnit::!SelectEntityVariant(name) (currently only one selection can be made at a time, since I assume that's the most convenient interface), which is called by the entity when its state changes (e.g. when it starts chopping wood). (TODO: Determine what "state" means, and the exact strings that should be used.)
Actor-level selections are usually either specified when reading the map (for units that were created in the editor, or for loading a saved game), or else are not specified at all. When they are not specified, random selections will be made and then added to the actor selections list. (TODO: Should/can this be network-synchronised?)
The selections, and the resultant variation, are remembered in the !ObjectEntry. When changes are made to the selections, the !ObjectEntry rebuilds its model data to match the new variation.
