Class: Ray::Animation::Combination

Inherits:
Ray::Animation show all
Defined in:
lib/ray/animation/combination.rb

Overview

This class allows to use a single object to apply several kind of animations to a same target.

Note combining two animations affecting the same attribute usually won’t work.

Thus:

translation(:of => [10, 10], :duration => 2) +
  translation(:of => [10, 10], :duration => 2)

Is not the same as:

translation(:of => [20, 20], :duration => 2)
