Detailed Description

A base class for all animations.

Constructor & Destructor Documentation

AnimationBase()

AnimationBase::AnimationBase

(

Ipo *

ipo

)

Special constructor which takes one IPO (or curve).

This is used by the

Member Function Documentation

getAt()

void AnimationBase::getAt ( float  time, Vec3 *  xyz = NULL, Vec3 *  hpr = NULL, Vec3 *  scale = NULL  )

virtual

Return the time, position and rotation at the specified time.

It does not update the internal timer as update() does.

Parameters

dt	Time since last call.
xyz	Position to be updated.
hpr	Rotation to be updated.

getDerivativeAt()

void AnimationBase::getDerivativeAt ( float  time, Vec3 *  xyz  )

virtual

Returns the derivative at the specified point.

Parameters

time	The time for which to determine the derivative.
xyz	Float pointer to store the result.

setInitialTransform()

void AnimationBase::setInitialTransform	(	const Vec3 &	xyz,
		const Vec3 &	hpr
	)

Stores the initial transform (in the IPOs actually).

This is necessary for relative IPOs.

Parameters

xyz	Position of the object.
hpr	Rotation of the object.

update() [1/2]

virtual void AnimationBase::update ( float  dt )

inlinevirtual

This needs to be implemented by the inheriting classes.

It is called once per frame from the track. It has a dummy implementation that just asserts so that this class can be instantiated in CannonAnimation.

Reimplemented in ThreeDAnimation.

update() [2/2]

void AnimationBase::update ( float  dt, Vec3 *  xyz = NULL, Vec3 *  hpr = NULL, Vec3 *  scale = NULL  )

virtual

Updates the time, position and rotation.

Called once per frame.

Parameters

dt	Time since last call.
xyz	Position to be updated.
hpr	Rotation to be updated.
