|
// Entity class.
|
|
//
|
|
// Usage: Do not attempt to instantiate this class directly. (See EntityManager.h)
|
|
// Most of the members are trivially obvious; some highlights are:
|
|
//
|
|
// HEntity me: is a reference to this entity. Use instead of the address-of operator for
|
|
// non-temporary references. See EntityHandles.h
|
|
// When an entity dies, this should be set to refer to the bad-handle handle.
|
|
// CUnit* m_actor: is the visible representation of this entity.
|
|
// std::hash_map m_properties: isn't yet used, is capable of storing properties defined by script.
|
|
//
|
|
// snapToGround(): Called every frame, this will ensure the entity never takes flight.
|
|
// updateActorTransforms(): Must be called every time the position of this entity changes.
|
|
// Also remember to update the collision object if you alter the position directly.
|
|
//
|
|
// Some notes: update() and dispatch() /can/ be called directly without ill effects,
|
|
// but it's preferable to go through the Entity manager and the Scheduler, respectively.
|
|
//
|
|
// Collision detection/avoidance is now present in some form; this is a work in progress.
