Unity C#如何避免轻击并仅通过滑动按字符移动

using UnityEngine;
using UnityEngine.EventSystems;

public class SwipeMovement : MonoBehaviour, IDragHandler, IEndDragHandler
{
    private Vector2 startPosition;
    private Vector2 endPosition;

    public float swipeThreshold = 100f; // 设置滑动的阈值

    public void OnDrag(PointerEventData eventData)
    {
        // 当拖动开始时记录起始位置
        if (eventData.delta.magnitude > 0)
        {
            startPosition = eventData.position;
        }
    }

    public void OnEndDrag(PointerEventData eventData)
    {
        // 当拖动结束时记录结束位置
        endPosition = eventData.position;

        // 计算滑动距离
        float swipeDistance = Vector2.Distance(startPosition, endPosition);

        // 判断滑动距离是否超过阈值
        if (swipeDistance > swipeThreshold)
        {
            // 计算滑动方向
            Vector2 swipeDirection = endPosition - startPosition;

            // 根据滑动方向执行相应的操作
            if (swipeDirection.x > 0)
            {
                // 向右滑动
                MoveRight();
            }
            else if (swipeDirection.x < 0)
            {
                // 向左滑动
                MoveLeft();
            }
        }
    }

    private void MoveRight()
    {
        // 向右移动字符的逻辑代码
    }

    private void MoveLeft()
    {
        // 向左移动字符的逻辑代码
    }
}
