使用Unity中的光线投射(2D)尝试拾取相对于玩家位置的对象

using UnityEngine;

public class ObjectPicker : MonoBehaviour
{
    public Transform player; // 玩家的Transform组件

    void Update()
    {
        if (Input.GetMouseButtonDown(0))
        {
            Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);

            // 构建射线
            Vector2 direction = mousePosition - (Vector2)player.position;
            Ray2D ray = new Ray2D(player.position, direction.normalized);

            // 进行光线投射
            RaycastHit2D hit = Physics2D.Raycast(ray.origin, ray.direction);

            // 处理相交结果
            if (hit.collider != null)
            {
                // 获取相交点的物体信息
                GameObject hitObject = hit.collider.gameObject;
                Debug.Log("拾取到物体：" + hitObject.name);
            }
        }
    }
}
