GraphicsFeature::GraphicsProperty Class Reference
#include <graphicsproperty.h>
Inheritance diagram for GraphicsFeature::GraphicsProperty:
Detailed Description
This is the standard graphics property which adds visibility to a game entity.NOTE: There are cases where the graphics property may depend on a physics property (for complex physics entities which require several graphics entities to render themselves). Thus it is recommended that physics properties are attached before graphics properties.

Member Function Documentation
| void GraphicsFeature::GraphicsProperty::OnActivate | ( | ) | [virtual] |
called from Entity::ActivateProperties()
Attach the property to a game entity. This will create and setup the required graphics entities.
Reimplemented from Game::Property.
Reimplemented in StateObjectFeature::StateGraphicsProperty.
| void GraphicsFeature::GraphicsProperty::OnDeactivate | ( | ) | [virtual] |
called from Entity::DeactivateProperties()
Remove the property from its game entity. This will release the graphics entities owned by the property.
Reimplemented from Game::Property.
Reimplemented in StateObjectFeature::StateGraphicsProperty.
| const Util::String & GraphicsFeature::GraphicsProperty::GetGraphicsResource | ( | ) | const [inline, virtual] |
override to provide a self managed graphics resource (default is Attr::Graphics)
Get the default graphics resource, which is Attr::Graphics. subclasses may override this to provide a self managed resource.
| void GraphicsFeature::GraphicsProperty::SetupGraphicsEntities | ( | ) | [protected, virtual] |
setup graphics entities
Setup the graphics entities. You may override this method in a subclass if different setup is needed.
Reimplemented in GraphicsFeature::ActorGraphicsProperty.
| void GraphicsFeature::GraphicsProperty::UpdateTransform | ( | const Math::matrix44 & | m, | |
| bool | setDirectly = false | |||
| ) | [protected, virtual] |
update the graphics entity's transform
Called to update the graphics entity's transform.
| void GraphicsFeature::GraphicsProperty::SetVisible | ( | bool | visible | ) | [protected] |
Shows or hides all attached graphics entities.
| 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::OnStart | ( | ) | [virtual, inherited] |
called from within Entity::OnStart() after OnLoad when the complete world exist
This method is called from within Game::Entity::OnStart(). This is the moment when the world is complete and the entity can establish connections to other entitys.
Reimplemented in GraphicsFeature::CameraProperty.
| 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::OnRender | ( | ) | [virtual, inherited] |
called before rendering happens
This method is called from Game::Entity::OnRender() on all properties attached to an entity in the order of attachment. Override this method if your property has any work to do before rendering happens.
Reimplemented in GraphicsFeature::CameraProperty, GraphicsFeature::ChaseCameraProperty, and GraphicsFeature::MayaCameraProperty.
| 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.
| int Core::RefCounted::GetRefCount | ( | ) | const [inline, inherited] |

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