Also split Entity.cpp further, moving the rendering code to EntityRendering.cpp and the JS interface code to EntityScriptInterface.cpp. This makes each individual file smaller (about 1000 lines still!) and lets them be compiled independently. This was SVN commit r4314.

// 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.
