	Returns the unique id for this component.

void	SetUniqueID (plUInt32 uiUniqueID)

void	EnsureInitialized ()
	Ensures that the component is initialized. Must only be called from another component's Initialize callback.

void	EnsureSimulationStarted ()
	Ensures that the OnSimulationStarted method has been called. Must only be called from another component's OnSimulationStarted callback.

PL_ALWAYS_INLINE bool	SendMessage (plMessage &ref_msg)
	Sends a message to this component.

PL_ALWAYS_INLINE bool	SendMessage (plMessage &ref_msg) const

void	PostMessage (const plMessage &msg, plTime delay=plTime::MakeZero(), plObjectMsgQueueType::Enum queueType=plObjectMsgQueueType::NextFrame) const
	Queues the message for the given phase. The message is processed after the given delay in the corresponding phase.

virtual bool	HandlesMessage (const plMessage &msg) const
	Returns whether the given Message is handled by this component.

void	SetUserFlag (plUInt8 uiFlagIndex, bool bSet)
	Be careful to check which flags may already be in use by base classes.

bool	GetUserFlag (plUInt8 uiFlagIndex) const
	Retrieves a custom flag. Index must be between 0 and 7.

void	SetCreatedByPrefab ()
	Adds plObjectFlags::CreatedByPrefab to the component. See the flag for details.

virtual void	Initialize ()
	Can be overridden for basic initialization that depends on a valid hierarchy and position.

virtual void	Deinitialize ()

virtual void	OnActivated ()
	This method is called when the component gets activated.

virtual void	OnDeactivated ()
	This method is called when the component gets deactivated.

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

virtual bool	OnUnhandledMessage (plMessage &msg, bool bWasPostedMsg)
	When EnableUnhandledMessageHandler() was activated, this is called for all messages for which there is no dedicated message handler.

virtual bool	OnUnhandledMessage (plMessage &msg, bool bWasPostedMsg) const

Detailed Description

This component polls all input events from the given input set every frame and broadcasts the information to components on the same game object.

To deactivate input handling, just deactivate the entire component. To use the input data, add a message handler on another component and handle messages of type plMsgInputActionTriggered. For every input event, one such message is sent every frame. The granularity property defines for which input events (key pressed, released or down) messages are sent.

Member Function Documentation

◆ DeserializeComponent()

void plInputComponent::DeserializeComponent ( plWorldReader & inout_stream )

overridevirtual

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.

Reimplemented from plComponent.

◆ GetCurrentInputState()

float plInputComponent::GetCurrentInputState	(	const char *	szInputAction,
		bool	bOnlyKeyPressed = false ) const

Returns the amount to which szInputAction is active (0 to 1).

If bOnlyKeyPressed is set to true, only key press events return a non-zero value, ie key down and key released events are ignored.

◆ SerializeComponent()

void plInputComponent::SerializeComponent ( plWorldWriter & inout_stream ) const

overridevirtual

Override this to save the current state of the component to the given stream.

Reimplemented from plComponent.
