Detailed Description

The object class is designed to optimize entity queries.

CGroupEntity will store query results; however, in some cases, it will re-query, such as when an entity is created or destroyed by CEntityManager, or when the notifyNeedQuery method is called.

Example of creating a group, that only queries entities containing CPrimiviteData.

const u32 primitive[] = GET_LIST_ENTITY_DATA(CPrimiviteData);
CEntityGroup* group = entityManager->createGroup(primitive, 1);

This method also creates a group that queries entities with CPrimiviteData, but only if those entities are visible (visible = true)

const u32 primitive[] = GET_LIST_ENTITY_DATA(CPrimiviteData);
CEntityGroup* group = entityManager->createGroupFromVisible(primitive, 1);
