Class Detail

cc.MotionStreak()
cc.MotionStreak manages a Ribbon based on it's motion in absolute space.
You construct it with a fadeTime, minimum segment size, texture path, texture
length and color. The fadeTime controls how long it takes each vertex in
the streak to fade out, the minimum segment size it how many pixels the
streak will move before adding a new ribbon segment, and the texture
length is the how many pixels the texture is stretched across. The texture
is vertically aligned along the streak segment.
