Public Member Functions
	ParameterTransition (const plist::PrimitiveBase &srcVal, plist::PrimitiveBase &dstVal, std::set< ParameterTransition * > &activeTrans, unsigned int dur)
	constructor, specify source to be monitored, destination to be kept in sync, a collection to be updated when transitions are in progress, and desired duration of transitions
	~ParameterTransition ()
	destructor
virtual void	plistValueChanged (const plist::PrimitiveBase &)
	This will be called whenever a plist you have registered with is changed.
bool	update (unsigned int curTime)
Public Attributes
const plist::PrimitiveBase &	src
	the parameter which is being monitored for changes (a member of the superclass of XWalkMC)
plist::PrimitiveBase &	dst
	the parameter which is updated with smoothly transitioning values based on src
std::set< ParameterTransition * > &	active
	collection which ParameterTransition will insert itself when src has been changed and transition is in progress
float	curd
	current velocity of parameter (d for derivative)
float	cura
	current acceleration of parameter
unsigned int	startTime
	time at which src was changed
unsigned int	duration
	how much time to use in transitioning (cura is then based on difference between src and dst, and this)
unsigned int	lastUpdate
	time of last call to update() or reset()
bool	decelerate
	set to true if in the deceleration phase of transitioning

Member Function Documentation

void XWalkMC::ParameterTransition::plistValueChanged ( const plist::PrimitiveBase & pl ) [virtual]

This will be called whenever a plist you have registered with is changed.

pl is const to help you avoid infinite recursion from an accidental modification of pl's value -- use a const cast if you're sure you know what you're doing

Implements plist::PrimitiveListener.
