unity中如何让一个对象沿着路径点循环移动

public List<Vector3> List_PathPoint = new List<Vector3>();
public float MoveSpeed = 5f;

private int currentPathIndex = 0;

void Update()
{
    // 获取当前指向的路径点
    Vector3 currentTarget = List_PathPoint[currentPathIndex];

    // 计算移动方向和距离
    Vector3 moveDirection = currentTarget - transform.position;
    float distanceToTarget = moveDirection.magnitude;

    // 如果距离小于可以接受的误差，则移动到下一个路径点
    if (distanceToTarget < 0.1f)
    {
        currentPathIndex++;
        if (currentPathIndex >= List_PathPoint.Count)
        {
            currentPathIndex = 0;
        }
    }
    else
    {
        // 向下一个路径点移动
        Vector3 moveVector = moveDirection.normalized * MoveSpeed * Time.deltaTime;
        transform.position += moveVector;
    }
}
