Inheritance diagram for GraphicsFeature::CameraProperty:
Detailed Description
A camera property adds the ability to manipulate the camera to an entity. Please note that more advanced camera properties should always be derived from the class camera property if camera focus handling is desired, since the FocusManager will only work on game entities which have a CameraProperty (or a subclass) attached.It is completely ok though to handle camera manipulation in a property not derived from CameraProperty, but please be aware that the FocusManager will ignore those.
The camera property will generally

Member Function Documentation
| void GraphicsFeature::CameraProperty::OnObtainCameraFocus | ( | ) | [virtual] |
called when camera focus is obtained
This method is called by the FocusManager when our entity gains the camera focus. Override this method if your subclass needs to do some initialization when gaining the camera focus.
Reimplemented in GraphicsFeature::ChaseCameraProperty.
| void GraphicsFeature::CameraProperty::OnLoseCameraFocus | ( | ) | [virtual] |
called when camera focus is lost
This method is called by the FocusManager when our entity loses the camera focus. Override this method if your subclass needs to do any cleanup work here.
| void GraphicsFeature::CameraProperty::OnRender | ( | ) | [virtual] |
called before rendering happens
Called before camera is "rendered". The default camera properties applies shake effects to the camera.
Reimplemented from Game::Property.
Reimplemented in GraphicsFeature::ChaseCameraProperty, and GraphicsFeature::MayaCameraProperty.
| bool GraphicsFeature::CameraProperty::HasFocus | ( | ) | const [virtual] |
return true if currently has camera focus
This method returns true if our entity has the camera focus. This implementation makes sure that 2 properties cannot report that they have the camera focus by accident.
| void Game::Property::OnActivate | ( | ) | [virtual, inherited] |
called from Entity::ActivateProperties()
This method is called by Game::Entity::ActivateProperties(). Use this method for one-time initializations of the property.
Reimplemented in GraphicsFeature::ChaseCameraProperty, GraphicsFeature::GraphicsProperty, GraphicsFeature::MayaCameraProperty, PhysicsFeature::ActorPhysicsProperty, PhysicsFeature::PhysicsProperty, PhysicsFeature::TriggerProperty, and StateObjectFeature::StateGraphicsProperty.
| void Game::Property::OnLoad | ( | ) | [virtual, inherited] |
called from within Entity::Load() after attributes are loaded
This method is called from within Game::Entity::Load() after the entity attributes have been loaded from the database. You can override this method in a subclass if further initialization is needed for the property after attributes have been loaded from the database, but please be aware that this method may not be called if the entity is created directly.
Reimplemented in PhysicsFeature::TriggerProperty, and StateObjectFeature::StateProperty.
| void Game::Property::OnSave | ( | ) | [virtual, inherited] |
called from within Entity::Save() before attributes are saved back to database
This method is called from within Game::Entity::Save() before the entity attributes will be saved to the database. You can override this method in a subclass if actions are needed before a save happens (this is usually the case if entity attributes need to be updated by the property before saving).
Reimplemented in PhysicsFeature::TriggerProperty, and StateObjectFeature::StateProperty.
| void Game::Property::OnBeginFrame | ( | ) | [virtual, inherited] |
called on begin of frame
This method is called from Game::Entity::OnBeginFrame() on all properties attached to an entity in the order of attachment. Override this method if your property has to do any work at the beginning of the frame.
Reimplemented in PhysicsFeature::TriggerProperty, and StateObjectFeature::StateProperty.
| void Game::Property::OnMoveBefore | ( | ) | [virtual, inherited] |
called before movement happens
This method is called from Game::Entity::OnMoveBefore() on all properties attached to an entity in the order of attachment. Override this method if your property has any work to do before the physics subsystem is triggered.
Reimplemented in PhysicsFeature::ActorPhysicsProperty.
| void Game::Property::OnMoveAfter | ( | ) | [virtual, inherited] |
called after movement has happened
This method is called from Game::Entity::OnMoveAfter() on all properties attached to an entity in the order of attachment. Override this method if your property has any work to do after the physics subsystem has been triggered.
Reimplemented in PhysicsFeature::ActorPhysicsProperty, and PhysicsFeature::PhysicsProperty.
| void Game::Property::OnRenderDebug | ( | ) | [virtual, inherited] |
called when game debug visualization is on
This method is called from Game::Entity::OnRenderDebug() on all properties attached to an entity in the order of attachment. It's meant for debug issues. It will be called when debug mode is enabled.
Reimplemented in GraphicsFeature::GraphicsProperty, PhysicsFeature::ActorPhysicsProperty, and PhysicsFeature::TriggerProperty.
| void Game::Property::OnLoseActivity | ( | ) | [virtual, inherited] |
called when game debug visualization is on
This method is called from Game::Entity::OnLoseActivity() on all properties attached to an entity in the order of attachment. It indicates that the entity will no longer be trigger, due to leaving the "Activity Bubble", i.e. the area of interest (most probably around the active camera).
Reimplemented in PhysicsFeature::ActorPhysicsProperty.
| void Game::Property::OnGainActivity | ( | ) | [virtual, inherited] |
called when game debug visualization is on
This method is called from Game::Entity::OnRenderDebug() on all properties attached to an entity in the order of attachment. It indicates that the entity will be trigger from now on, due to entering the "Activity Bubble", i.e. the area of interest (most probably around the active camera).
attach a message handler to the port
Attach a message handler to the port.
remove a message handler from the port
Remove a message handler from the port.
send a message to the port
Send a message to the port. This will immediately call the HandleMessage() method of all attached handlers. If the message has been handled by at least one of the handlers, the Handled() flag of the message will be set to true.

Return the current refcount of the object.
| void Core::RefCounted::AddRef | ( | ) | [inline, inherited] |
increment refcount by one

Decrement the refcount and destroy object if refcount is zero.
| const Util::String & Core::RefCounted::GetClassName | ( | ) | const [inline, inherited] |
get the class name
Get the class name of the object.
| Util::FourCC Core::RefCounted::GetClassFourCC | ( | ) | const [inline, inherited] |

Get the class FourCC of the object.
| void Core::RefCounted::DumpRefCountingLeaks | ( | ) | [static, inherited] |
dump refcounting leaks, call at end of application (NEBULA3_DEBUG builds only!)
This method should be called as the very last before an application exits.
