Overview

Animations lists are collections of animations, updating them and removing all the animations that are done running. As this the only thing you’ll need to do most of the time, you can just push an animation at the end of it and let Scene do the rest of the work.

Examples:

animations << color_variation(:from => [255, 0, 0], :to => [0, 255, 0],
                              :duration => 3).start(sprite)
