NAME

cue - a loop with start time and end time; cues are used to compose a scene.

DESCRIPTION

Cue is a subclass of loop that provides extra instance variables to control when to start and stop itself. Cues are used by scenes to create animation sequences. Typically, many cues are provided to a scene, each cue starting at its start time and ending at its end time.

Like loop, cue has start, tick, and end actions that are executed at the beginning, during, and at the completion of the cue. A more extensive description of these instance variables and methods can be found in the loop man page.
