Unity中UGUI轮播Image

思想：把一组图片放到Scroll View下，把超出屏幕的Image塞到最后，然后继续续播放。
找的Gif制作软件有水印，将就着看…

看下去掉mask后的效果：

废话不多说，放代码：

public abstract class PictureRotationUI<T> : MonoBehaviour where T:MonoBehaviour
{
    private Transform content1;
    private Transform startPos;
    private Transform endPos;
    private Transform[] childItem;

    protected virtual void Awake()
    {
        content1 = transform.GetChild(0).GetChild(0).transform;
        childItem = new Transform[content1.childCount];
        for (int i = 0; i < content1.childCount; i++)
        {
            childItem[i] = content1.GetChild(i).transform;
        }
        startPos = transform.Find("Viewport/startPosition").transform;
        endPos = transform.Find("Viewport/endPosition").transform;
    }
 
    protected virtual void Move(bool isMove,float speed)
    {
        if (isMove)
        {
            for (int i = 0; i < childItem.Length; i++)
            {
                childItem[i].transform.position = new Vector3(childItem[i].transform.position.x-speed*Time.deltaTime,childItem[i].transform.position.y,childItem[i].transform.position.z);
                if (childItem[i].transform.position.x<=endPos.position.x)
                {
                    childItem[i].transform.position = startPos.position;
                }
            }
        }
    }
}

鼠标进入和鼠标退出：

public class PictureItem : MonoBehaviour, IPointerEnterHandler,IPointerExitHandler
{
    TestPicture pic;
    RectTransform rect;

    void Start()
    {
        pic = transform.parent.parent.parent.GetComponent<TestPicture>();
        rect = this.GetComponent<RectTransform>();
    }

    public void OnPointerEnter(PointerEventData eventData)
    {
        pic.isMove = false;
        rect.sizeDelta = new Vector2(230,230);
    }

    public void OnPointerExit(PointerEventData eventData)
    {
        pic.isMove = true;
        rect.sizeDelta = new Vector2(200, 200);

    }
}
