Detailed Description

Base class of all component types.

Derive from this class to implement custom component types. Also add the PL_DECLARE_COMPONENT_TYPE macro to your class declaration. Also add a PL_BEGIN_COMPONENT_TYPE/PL_END_COMPONENT_TYPE block to a cpp file. In that block you can add reflected members or message handlers. Note that every component type needs a corresponding manager type. Take a look at plComponentManagerSimple for a simple manager implementation that calls an update method on its components every frame. To create a component instance call CreateComponent on the corresponding manager. Never store a direct pointer to a component but store an plComponentHandle instead.

Member Function Documentation

Deinitialize()

void plComponent::Deinitialize ( )

protectedvirtual

This method is called before the component is destroyed. A derived type can override this method to do common de-initialization work.

This function is always called before destruction, even if the component is currently not active. The default implementation checks whether the component is currently active and will ensure OnDeactivated() gets called if necessary. For typical game code, prefer to use OnDeactivated().

DeserializeComponent()

void plComponent::DeserializeComponent ( plWorldReader & inout_stream )

virtual

Override this to load the current state of the component from the given stream.

The active state will be automatically serialized. The 'initialized' state is not serialized, all components will be initialized after creation, even if they were already in an initialized state when they were serialized.

GetActiveFlag()

PL_ALWAYS_INLINE bool plComponent::GetActiveFlag

(

)

const

Checks whether the 'active flag' is set on this component. Note that this does not mean that the component is also 'active'.

See also

IsActive(), SetActiveFlag()

HandlesMessage()

bool plComponent::HandlesMessage ( const plMessage & msg ) const

virtual

Returns whether the given Message is handled by this component.

Reimplemented in plForwardEventsToGameStateComponent, and plTypeScriptComponent.

Initialize()

void plComponent::Initialize ( )

protectedvirtual

Can be overridden for basic initialization that depends on a valid hierarchy and position.

All trivial initialization should be done in the constructor. For typical game code, you should prefer to use OnSimulationStarted(). This method is called once for every component, after creation but only at the start of the next world update. Therefore the global position has already been computed and the owner plGameObject is set. Contrary to OnActivated() and OnSimulationStarted(), this function is always called for all components.

IsActive()

PL_ALWAYS_INLINE bool plComponent::IsActive

(

)

const

Checks whether this component is in an active state.

The active state is determined by the active state of the owning game object and the 'active flag' of this component. Only if the owning game object is active (and thus all of its parent objects as well) and the component has the active flag set, will this component be active.

See also

plGameObject::IsActive(), plGameObject::SetActiveFlag()

IsActiveAndInitialized()

PL_ALWAYS_INLINE bool plComponent::IsActiveAndInitialized

(

)

const

Returns whether this component is active and initialized.

See also

IsActive()

IsActiveAndSimulating()

PL_ALWAYS_INLINE bool plComponent::IsActiveAndSimulating

(

)

const

Whether the component is currently active and simulation has been started as well.

See also

IsActive()

OnActivated()

void plComponent::OnActivated ( )

protectedvirtual

This method is called when the component gets activated.

By default a component is active, but it can be created in an inactive state. In such a case OnActivated() is only called once a component is activated. If a component gets switched between active and inactive at runtime, OnActivated() and OnDeactivated() are called accordingly. In contrast Initialize() and Deinitialize() are only ever called once.

OnDeactivated()

void plComponent::OnDeactivated ( )

protectedvirtual

This method is called when the component gets deactivated.

Upon destruction, a component that is active first gets deactivated. Therefore OnDeactivated() should be used for typical game code cleanup.

OnSimulationStarted()

void plComponent::OnSimulationStarted ( )

protectedvirtual

This method is called once for active components, at the start of the next world update, but only when the world is simulated.

This is the one preferred method to setup typical game logic. In a pure game environment there is no practical difference between OnActivated() and OnSimulationStarted(), as OnSimulationStarted() will be called right after OnActivated().

However, when a scene is open inside the editor, there is an important difference: OnActivated() is called once the component was created. OnSimulationStarted() is only called once the game simulation is started inside the editor. As an example, if a component starts a sound in OnActivated(), that sound will play right after the scene has been loaded into the editor. If instead the sound gets started in OnSimulationStarted(), it will only play once the user starts the game mode inside the editor.

Additionally, OnSimulationStarted() is only ever executed once on a component, even if the plWorld pauses and resumes world simulation multiple times. Thus components that should only execute a thing exactly once, will work correctly. In contrast OnActivated() and OnDeactivated() will be executed every time the component's active state is toggled, which could re-execute the same behavior multiple times.

SetActiveFlag()

void plComponent::SetActiveFlag

(

bool

bEnabled

)

Sets the active flag of the component, which affects its active state.

The active flag affects the 'active state' of the component. Ie. a component without the active flag will always be inactive. However, the active state is also affected by the active state of the owning game object. Thus a component attached to an inactive game object, will also be inactive.

Note that it is up to the component manager though, whether it differentiates between active and inactive components.
