TweenSequence Class Reference

Detailed Description

Plays a list of Tweens sequentially, one after the other.

When the active Tween finishes mid-frame, the leftover delta is passed immediately to the next Tween so there is no one-frame gap between steps. An optional callback is invoked once the last Tween completes.

Constructor & Destructor Documentation

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

Creates a sequence from an ordered list of Tweens.

Parameters
tweensTweens to play in order; ownership is transferred.
callbackOptional function invoked when the last Tween completes.

Member Function Documentation

bool isRunning ( ) const
inlineoverridevirtual

Returns true while the Tween is still animating.

Reimplemented from lysa::Tween::isRunning()

void kill ( )
inlineoverridevirtual

Immediately stops the Tween without firing the completion callback.

Reimplemented from lysa::Tween::kill()

bool update ( double  deltaTime)
overridevirtual

Advances the Tween by delta time.

Parameters
deltaTimeTime elapsed since the previous update (seconds).
Returns
true when the Tween has finished, false while it is running.
