Unity 实现Image轮播图效果_untity 轮播图

废话不多说，上代码

using UnityEngine;
using UnityEngine.UI;
 
public class ImageCarousel : MonoBehaviour
{
    [SerializeField] private Image[] images; // 将需要轮播的所有图片拖拽到这个数组中
    [SerializeField] private float transitionDuration = 1f; // 图片切换过渡时间
    [SerializeField] private bool loop = true; // 是否循环播放
 
    private int currentImageIndex = 0;
    private bool isTransitioning = false;
 
    void Start()
    {
        if (images.Length > 0)
        {
            ShowCurrentImage();
            StartCoroutine(StartTransition());
            InvokeRepeating("NextImage", transitionDuration, transitionDuration);
        }
    }
 
    IEnumerator StartTransition()
    {
        while (true)
        {
            if (!isTransitioning && images.Length > 1)
            {
                isTransitioning = true;
                LeanTween.alpha(images[currentImageIndex].rectTransform, 0f, transitionDuration).setEaseInOutSine().setOnComplete(() =>
                {
                    currentImageIndex = (currentImageIndex + 1) % images.Length; // 循环索引
                    images[currentImageIndex].gameObject.SetActive(true); // 显示下一张图片
                    LeanTween.alpha(images[currentImageIndex].rectTransform, 1f, transitionDuration).setEaseInOutSine().setOnComplete(() => isTransitioning = false);
                });
            }
            yield return null;
        }
    }
 
    void NextImage()
    {
        if (!loop && currentImageIndex == images.Length - 1) return; // 如果不循环且已经是最后一张图片，则停止
 
        StopAllCoroutines(); // 停止当前所有的协程以防止叠加
        StartCoroutine(StartTransition()); // 开始新的过渡动画
    }
 
    void ShowCurrentImage()
    {
        foreach (var image in images)
        {
            image.gameObject.SetActive(false);
        }
        images[currentImageIndex].gameObject.SetActive(true);
    }
}
