生成物体片段

曾经使用世界坐标点生成物体，结果被tilemap覆盖了

        // 屏幕坐标 转 世界坐标
        Vector3 wordPos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        //Debug.LogError(wordPos);
        // 世界坐标 转 格子坐标
        Vector3Int callPos = GoodsLayer.WorldToCell(wordPos);
        //// 格子坐标 转 世界坐标
        Vector3 createPostion = GoodsLayer.CellToWorld(callPos);



        //2d检测 鼠标下的物体
        Ray myRay = Camera.main.ScreenPointToRay(Input.mousePosition);
        Debug.Log(myRay);
        //RaycastHit2D hit = Physics2D.Raycast(new Vector2(myRay.origin.x, myRay.origin.y), Vector2.down,2);
        RaycastHit2D hit = Physics2D.Raycast(new Vector2(createPostion.x, createPostion.y), Vector2.down, 2);
        Debug.Log(hit);
        Debug.Log(hit.collider);
        if (hit.collider != null)
        {
            //do something print (hit.collider);
            Debug.Log("2d物体名称:" + hit.collider.name);
        }
        else
        {
            GoodsLayer.SetTile(callPos, tile);
            //GoodsLayer.BoxFill(callPos, tile,0,0,5,5);
            //tilemap.RefreshAllTiles();
            //GoodsLayer.RefreshAllTiles();

            //GameObject.Find("Grid/Goods").transform
            //GameObject.Instantiate(goods, new Vector3(createPostion.x, createPostion.y, -1), Quaternion.identity);
        }
