Member Function Documentation

void Game::Property::SetupCallbacks (  )  [virtual, inherited]

setup callbacks for this property, call by entity in OnActivate()

Tells the entity what per-frame callback methods should be called for this property. The method is called after SetupDefaultAttributes() by the entity, and the property is expected to call the Entity::RegisterPropertyCallback() once for every callback method (OnBeginFrame(), OnMoveBefore(), ...) that should be called per-frame.

Reimplemented in GraphicsFeature::CameraProperty, GraphicsFeature::GraphicsProperty, GraphicsFeature::MayaCameraProperty, PhysicsFeature::ActorPhysicsProperty, PhysicsFeature::PhysicsProperty, PhysicsFeature::TriggerProperty, and StateObjectFeature::StateProperty.

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::OnDeactivate (  )  [virtual, inherited]

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::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).

void Messaging::Port::AttachHandler ( const Ptr< Handler > &  h  )  [inherited]

attach a message handler to the port

Attach a message handler to the port.

void Messaging::Port::RemoveHandler ( const Ptr< Handler > &  h  )  [inherited]

remove a message handler from the port

Remove a message handler from the port.

void Messaging::Port::Send ( const Ptr< Message > &  msg  )  [virtual, inherited]

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]

get the current refcount

Return the current refcount of the object.

void Core::RefCounted::AddRef (  )  [inline, inherited]

increment refcount by one

Increment the refcount of the object.

void Core::RefCounted::Release (  )  [inline, inherited]

decrement refcount and destroy object if refcount is zero

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 code

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.
