Public Member Functions

 Time (Context *context)
 Construct.
 
virtual ~Time ()
 Destruct. Reset the low-resolution timer period if set.
 
void BeginFrame (float timeStep)
 Begin new frame, with (last) frame duration in seconds and send frame start event.
 
void EndFrame ()
 End frame. Increment total time and send frame end event.
 
void SetTimerPeriod (unsigned mSec)
 Set the low-resolution timer period in milliseconds. 0 resets to the default period.
 
unsigned GetFrameNumber () const
 Return frame number, starting from 1 once BeginFrame() is called for the first time.
 
float GetTimeStep () const
 Return current frame timestep as seconds.
 
unsigned GetTimerPeriod () const
 Return current low-resolution timer period in milliseconds.
 
float GetElapsedTime ()
 Return elapsed time from program start as seconds.
 
- Public Member Functions inherited from Urho3D::Object
 Object (Context *context)
 Construct.
 
virtual ~Object ()
 Destruct. Clean up self from event sender & receiver structures.
 
virtual StringHash GetType () const =0
 Return type hash.
 
virtual const StringGetTypeName () const =0
 Return type name.
 
virtual const TypeInfoGetTypeInfo () const =0
 Return type info.
 
virtual void OnEvent (Object *sender, StringHash eventType, VariantMap &eventData)
 Handle event.
 
bool IsInstanceOf (StringHash type) const
 Check current instance is type of specified type.
 
bool IsInstanceOf (const TypeInfo *typeInfo) const
 Check current instance is type of specified type.
 
template<typename T >
bool IsInstanceOf () const
 Check current instance is type of specified class.
 
void SubscribeToEvent (StringHash eventType, EventHandler *handler)
 Subscribe to an event that can be sent by any sender.
 
void SubscribeToEvent (Object *sender, StringHash eventType, EventHandler *handler)
 Subscribe to a specific sender's event.
 
void UnsubscribeFromEvent (StringHash eventType)
 Unsubscribe from an event.
 
void UnsubscribeFromEvent (Object *sender, StringHash eventType)
 Unsubscribe from a specific sender's event.
 
void UnsubscribeFromEvents (Object *sender)
 Unsubscribe from a specific sender's events.
 
void UnsubscribeFromAllEvents ()
 Unsubscribe from all events.
 
void UnsubscribeFromAllEventsExcept (const PODVector< StringHash > &exceptions, bool onlyUserData)
 Unsubscribe from all events except those listed, and optionally only those with userdata (script registered events.)
 
void SendEvent (StringHash eventType)
 Send event to all subscribers.
 
void SendEvent (StringHash eventType, VariantMap &eventData)
 Send event with parameters to all subscribers. More...
 
VariantMapGetEventDataMap () const
 Return a preallocated map for event data. Used for optimization to avoid constant re-allocation of event data maps.
 
ContextGetContext () const
 Return execution context.
 
ObjectGetSubsystem (StringHash type) const
 Return subsystem by type.
 
ObjectGetEventSender () const
 Return active event sender. Null outside event handling.
 
EventHandlerGetEventHandler () const
 Return active event handler. Null outside event handling.
 
bool HasSubscribedToEvent (StringHash eventType) const
 Return whether has subscribed to an event without specific sender.
 
bool HasSubscribedToEvent (Object *sender, StringHash eventType) const
 Return whether has subscribed to a specific sender's event.
 
bool HasEventHandlers () const
 Return whether has subscribed to any event.
 
template<class T >
T * GetSubsystem () const
 Template version of returning a subsystem.
 
const StringGetCategory () const
 Return object category. Categories are (optionally) registered along with the object factory. Return an empty string if the object category is not registered.
 
- Public Member Functions inherited from Urho3D::RefCounted
 RefCounted ()
 Construct. Allocate the reference count structure and set an initial self weak reference.
 
virtual ~RefCounted ()
 Destruct. Mark as expired and also delete the reference count structure if no outside weak references exist.
 
void AddRef ()
 Increment reference count. Can also be called outside of a SharedPtr for traditional reference counting.
 
void ReleaseRef ()
 Decrement reference count and delete self if no more references. Can also be called outside of a SharedPtr for traditional reference counting.
 
int Refs () const
 Return reference count.
 
int WeakRefs () const
 Return weak reference count.
 
RefCountRefCountPtr ()
 Return pointer to the reference count structure.
