unity滚动视图超出的部分停下的脚本

你可以使用Unity的ScrollRect组件来实现滚动视图,并通过编写脚本控制滚动视图停止超出的部分。
以下是示例代码:
```csharp
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
public class ScrollViewController : MonoBehaviour, IBeginDragHandler, IEndDragHandler
{
public ScrollRect scrollRect;
public float scrollSpeed = 10f;
private bool isDragging = false;
private Vector2 targetPosition;
private void Start()
{
targetPosition = scrollRect.content.anchoredPosition;
}
private void Update()
{
if (!isDragging)
{
scrollRect.content.anchoredPosition = Vector2.Lerp(scrollRect.content.anchoredPosition, targetPosition, Time.deltaTime * scrollSpeed);
}
}
public void OnBeginDrag(PointerEventData eventData)
{
isDragging = true;
}
public void OnEndDrag(PointerEventData eventData)
{
isDragging = false;
float minDistance = Mathf.Infinity;
foreach (RectTransform child in scrollRect.content)
{
float distance = Mathf.Abs(scrollRect.content.anchoredPosition.y - child.anchoredPosition.y);
if (distance < minDistance)
{
minDistance = distance;
targetPosition = child.anchoredPosition;
}
}
}
}
```
这个脚本会在开始拖动滚动视图时停止滚动,然后在拖动结束时自动滚动到最接近的子项位置。你可以将这个脚本附加到你的ScrollRect组件上,并设置scrollRect变量为你的ScrollRect组件。你还可以调整scrollSpeed变量来控制滚动速度。
