Detailed Description

Specialised AnimationTrack for dealing with node transforms.

Constructor & Destructor Documentation

◆ NodeAnimationTrack() [1/2]

Ogre::NodeAnimationTrack::NodeAnimationTrack	(	Animation *	parent,
		unsigned short	handle
	)

Constructor.

◆ NodeAnimationTrack() [2/2]

Ogre::NodeAnimationTrack::NodeAnimationTrack	(	Animation *	parent,
		unsigned short	handle,
		Node *	targetNode
	)

Constructor, associates with a Node.

◆ ~NodeAnimationTrack()

virtual Ogre::NodeAnimationTrack::~NodeAnimationTrack ( )

virtual

Destructor.

Member Function Documentation

◆ createNodeKeyFrame()

virtual TransformKeyFrame * Ogre::NodeAnimationTrack::createNodeKeyFrame ( Real timePos )

virtual

Creates a new KeyFrame and adds it to this animation at the given time index.

It is better to create KeyFrames in time order.

Parameters

timePos The time from which this KeyFrame will apply.

◆ getAssociatedNode()

virtual Node * Ogre::NodeAnimationTrack::getAssociatedNode ( void ) const

virtual

Returns a pointer to the associated Node object (if any).

◆ setAssociatedNode()

virtual void Ogre::NodeAnimationTrack::setAssociatedNode ( Node * node )

virtual

Sets the associated Node object which will be automatically affected by calls to 'apply'.

◆ applyToNode()

virtual void Ogre::NodeAnimationTrack::applyToNode	(	Node *	node,
		const TimeIndex &	timeIndex,
		Real	weight = `1.0`,
		Real	scale = `1.0f`
	)

virtual

As the 'apply' method but applies to a specified Node instead of associated node.

◆ setUseShortestRotationPath()

virtual void Ogre::NodeAnimationTrack::setUseShortestRotationPath ( bool useShortestPath )

virtual

Sets the method of rotation calculation.

◆ getUseShortestRotationPath()

virtual bool Ogre::NodeAnimationTrack::getUseShortestRotationPath ( ) const

virtual

Gets the method of rotation calculation.

◆ getInterpolatedKeyFrame()

void Ogre::NodeAnimationTrack::getInterpolatedKeyFrame	(	const TimeIndex &	timeIndex,
		KeyFrame *	kf
	)		const

overridevirtual

Gets a KeyFrame object which contains the interpolated transforms at the time index specified.

The KeyFrame objects held by this class are transformation snapshots at discrete points in time. Normally however, you want to interpolate between these keyframes to produce smooth movement, and this method allows you to do this easily. In animation terminology this is called 'tweening'.

Parameters

timeIndex	The time (in relation to the whole animation sequence)
kf	Keyframe object to store results

Implements Ogre::AnimationTrack.

◆ apply()

void Ogre::NodeAnimationTrack::apply	(	const TimeIndex &	timeIndex,
		Real	weight = `1.0`,
		Real	scale = `1.0f`
	)

overridevirtual

Applies an animation track to the designated target.

Parameters

timeIndex	The time position in the animation to apply.
weight	The influence to give to this track, 1.0 for full influence, less to blend with other animations.
scale	The scale to apply to translations and scalings, useful for adapting an animation to a different size target.

Implements Ogre::AnimationTrack.

◆ _keyFrameDataChanged()

void Ogre::NodeAnimationTrack::_keyFrameDataChanged ( void ) const

overridevirtual

Internal method used to tell the track that keyframe data has been changed, which may cause it to rebuild some internal data.

Reimplemented from Ogre::AnimationTrack.

◆ getNodeKeyFrame()

virtual TransformKeyFrame * Ogre::NodeAnimationTrack::getNodeKeyFrame ( unsigned short index ) const

virtual

Returns the KeyFrame at the specified index.

◆ hasNonZeroKeyFrames()

bool Ogre::NodeAnimationTrack::hasNonZeroKeyFrames ( void ) const

overridevirtual

Method to determine if this track has any KeyFrames which are doing anything useful - can be used to determine if this track can be optimised out.

Reimplemented from Ogre::AnimationTrack.

◆ optimise()

void Ogre::NodeAnimationTrack::optimise ( void )

overridevirtual

Optimise the current track by removing any duplicate keyframes.

Reimplemented from Ogre::AnimationTrack.

◆ _clone()

NodeAnimationTrack * Ogre::NodeAnimationTrack::_clone ( Animation * newParent ) const

Clone this track (internal use only)

◆ _applyBaseKeyFrame()

void Ogre::NodeAnimationTrack::_applyBaseKeyFrame ( const KeyFrame * base )

overridevirtual

Internal method to re-base the keyframes relative to a given keyframe.

Reimplemented from Ogre::AnimationTrack.
