Action objects are just like they sound. They make a Node perform a change to its properties. Action objects allow the transformation of Node properties in time. Any object with a base class of Node can have Action objects performed on it. As an example, you can move a Sprite from one position to another and do it over a span of time.

Example of MoveTo and MoveBy action:

// Move sprite to position 50,10 in 2 seconds.
auto moveTo = MoveTo::create(2, Vec2(50, 10));

// Move sprite 20 points to right in 2 seconds
auto moveBy = MoveBy::create(2, Vec2(20,0));
