Jan and I implemented a number of changes: - Converted SClassSet to vector. - Refactored get/set ClassSet from string into methods in CClassSet. - Turned pass-by-value string params in getCollisionObject, CEntity constructor and CEntityManager into pointers. - Simplified processChooseMovement. - Merged CalculateRun and CalculateHealth into a single, simpler CalculateRegen + helper functions. - Changed the way regen works so the rates read in the XML act as rates (before, they were the number of seconds until the entity will be fully regenned, which is a bit counterintuitive). This was SVN commit r4167.

// Maintains entity id->object mappings. Does most of the work involved in creating an entity.
|
|
//
|
|
// Usage: Do not attempt to directly instantiate an entity class.
|
|
// HEntity bob = g_EntityManager.create( unit_class_name, position, orientation );
|
|
// or HEntity jim = g_EntityManager.create( pointer_to_unit_class, position, orientation );
|
|
//
|
|
// Perform updates on all world entities by g_EntityManager.updateAll( timestep )
|
|
// Dispatch an identical message to all world entities by g_EntityManager.dispatchAll( message_pointer )
|
|
// Get an STL vector container of all entities with a certain property with g_EntityManager.matches( predicate )
|
|
// or just get all entities with g_EntityManager.getExtant().
|
|
//
|
|
// Those last two functions - caller has responsibility for deleting the collection when you're done with it.
