CreateAnimation() публичный Метод

Creates an animation which can be used to animate scene nodes.

An animation is a collection of 'tracks' which over time change the position / orientation of Node objects. In this case, the animation will likely have tracks to modify the position / orientation of SceneNode objects, e.g. to make objects move along a path.

You don't need to use an Animation object to move objects around - you can do it yourself using the methods of the Node in your application. However, when you need relatively complex scripted animation, this is the class to use since it will interpolate between keyframes for you and generally make the whole process easier to manage.

A single animation can affect multiple Node objects (each AnimationTrack affects a single Node). In addition, through animation blending a single Node can be affected by multiple animations, although this is more useful when performing skeletal animation (see Skeleton.CreateAnimation).
