Constructor & Destructor Documentation

virtual ~Tweens ( )

virtual

Kills every Tween still registered.

void cleanup ( )

std::shared_ptr<Tween> property	(	O *	obj,
		void (O::*)(const T &)	set,
		T	initial,
		T	final,
		const float	duration,
		const TransitionType	ttype = `TransitionType::LINEAR`,
		const Tween::Callback &	callback = `nullptr`
	)

inline

Creates a PropertyTween that interpolates a property on an Object, registers it, and returns it. The target object must outlive the Tween.

Parameters

obj	The target object.
set	Member setter to call on the target object.
initial	Starting value applied at time 0.
final	Target value reached at the end of the duration.
duration	Animation duration in seconds (must be > 0).
ttype	Interpolation curve to use (default: LINEAR).
callback	Optional function invoked when the Tween completes.

std::shared_ptr<Tween> registerTween ( const std::shared_ptr< Tween > & tween )

Registers a Tween for automatic update each physics ticks

std::shared_ptr<TweenSequence> sequence	(	std::vector< std::shared_ptr< Tween >>	tweens,
		const Tween::Callback &	callback = `nullptr`
	)

Creates a TweenSequence, registers it, and returns it.

Parameters

tweens	Ordered list of Tweens; ownership is transferred.
callback	Optional function invoked when the last Tween completes.

void update ( double deltaTime )

Advances all registered Tweens and removes completed ones.
