Detailed Description

Animates a scene node. Can animate position, rotation, material, and so on.

A scene node animator is able to animate a scene node in a very simple way. It may change its position, rotation, scale and/or material. There are lots of animators to choose from. You can create scene node animators with the ISceneManager interface.

Member Function Documentation

◆ animateNode()

virtual void jpp::scene::ISceneNodeAnimator::animateNode	(	ISceneNode *	node,
		u32	timeMs
	)

pure virtual

Animates a scene node.

Parameters

node	Node to animate.
timeMs	Current time in milliseconds.

◆ cloneMembers()

void jpp::scene::ISceneNodeAnimator::cloneMembers ( const ISceneNodeAnimator * toCopyFrom )

inlineprotected

This method can be used by clone() implementations of derived classes

Parameters

toCopyFrom The animator from which the values are copied

◆ createClone()

virtual ISceneNodeAnimator * jpp::scene::ISceneNodeAnimator::createClone	(	ISceneNode *	node,
		ISceneManager *	newManager = `0`
	)

pure virtual

Creates a clone of this animator.

Please note that you will have to drop (IReferenceCounted::drop()) the returned pointer after calling this.

◆ deserializeAttributes()

virtual void jpp::scene::ISceneNodeAnimator::deserializeAttributes	(	io::IAttributes *	in,
		io::SAttributeReadWriteOptions *	options = `0`
	)

inlineoverridevirtual

Reads attributes of the scene node animator.

Reimplemented from jpp::io::IAttributeExchangingObject.

◆ getStartTime()

virtual jpp::u32 jpp::scene::ISceneNodeAnimator::getStartTime ( ) const

inlinevirtual

Get the starttime.

This will return 0 for by animators which don't work with a starttime unless a starttime was manually set

◆ hasFinished()

virtual bool jpp::scene::ISceneNodeAnimator::hasFinished ( void ) const

inlinevirtual

Returns if the animator has finished.

This is only valid for non-looping animators with a discrete end state.

Returns: true if the animator has finished, false if it is still running.

◆ isEventReceiverEnabled()

virtual bool jpp::scene::ISceneNodeAnimator::isEventReceiverEnabled ( ) const

inlinevirtual

Returns true if this animator receives events.

When attached to an active camera, this animator will be able to respond to events such as mouse and keyboard events.

◆ OnEvent()

virtual bool jpp::scene::ISceneNodeAnimator::OnEvent ( const SEvent & event )

inlineoverridevirtual

Event receiver, override this function for camera controlling animators.

Implements jpp::IEventReceiver.

◆ serializeAttributes()

virtual void jpp::scene::ISceneNodeAnimator::serializeAttributes	(	io::IAttributes *	out,
		io::SAttributeReadWriteOptions *	options = `0`
	)		const

inlineoverridevirtual

Writes attributes of the scene node animator.

Reimplemented from jpp::io::IAttributeExchangingObject.

◆ setEnabled()

virtual void jpp::scene::ISceneNodeAnimator::setEnabled	(	bool	enabled,
		u32	timeNow = `0`
	)

inlinevirtual

Sets the enabled state of this element.

Parameters

enabled	When set to false ISceneNodes will not update the animator anymore. Animators themselves usually don't care. So manual calls to animateNode still work.
timeNow	When set to values > 0 on enabling and disabling an internal timer will be increased by the time disabled time. Animator decide themselves how to handle that timer, but generally setting it will allow you to pause an animator, so it will continue at the same position when you enable it again. To use that pass jpp::ITimer::getTime() as value. Animators with no timers will just ignore this.

◆ setStartTime()

virtual void jpp::scene::ISceneNodeAnimator::setStartTime	(	u32	time,
		bool	resetPauseTime = `true`
	)

inlinevirtual

Reset a time-based movement by changing the starttime.

By default most animators start on object creation. This value is ignored by animators which don't work with a starttime. Known problems: CSceneNodeAnimatorRotation currently overwrites this value constantly (might be changed in the future).

Parameters

time	Commonly you will use jpp::ITimer::getTime().
resetPauseTime	Reset internal pause time for enabling/disabling animators as well
