Definition
• A tween is basically an interpolation between two
values that runs for a given amount of time.
• Tween Engine does a lot more than that, and handles
the life-cycles and the update mechanisms of the
interpolations for you. Moreover, it enables the
interpolation of attributes of some objects.

Why use tweening (engine)?
• Dynamic.
• You can modify your transitions, timing, values,
easings, and other attributes with only lines of code,
rather than telling your artist/animator to
animate/fixate the object. This will faster the
production time, too.
• Some tweening engine have motion path, too!

More on tweening (engine)
• Time : Time needed to complete a tween animation
• Delay : Time needed to start a tween animation
• Easing : Some equation to control the rate of
tweening
