Unity3D制作序列帧动画的方法

public class Test : MonoBehaviour {
 
 [SerializeField]
 private Image image;
 [SerializeField]
 private List<Sprite> animationSprites = new List<Sprite>();
 
 
 private int AnimationAmount { get { return animationSprites.Count; } }
 public void PlayAnimation()
 {
 if (image == null) image = GetComponent<Image>();
 StartCoroutine(PlayAnimationForwardIEnum());
 }
 
 private IEnumerator PlayAnimationForwardIEnum()
 {
 int index = 0;//可以用来控制起始播放的动画帧索引
 gameObject.SetActive(true);
 while (true)
 {
  //当我们需要在整个动画播放完之后 重复播放后面的部分 就可以展现我们纯代码播放的自由性
  if (index > AnimationAmount - 1)
  {
  index = 50;
  }
  image.sprite = animationSprites[index];
  index++;
  yield return new WaitForSeconds(0.03f);//等待间隔 控制动画播放速度
 }
 }
}
