animation code in c#

using UnityEngine;

// Animation.Play example. Let the S and J keys start
// a spin or jump animation. Let Space play back spin and
// jump at the same time. Let Z play spin and jump with
// spin doubled in speed.
//
// Spin: rotate the cube 360 degrees in half or one second
// Jump: bounce up to 2 units and down in one second
//
// Note: AnimationState.layer is no longer supported, but still exists.
