如何在unity 2d中获得玩家前面的方块？

using UnityEngine;

public class GetFrontBlock : MonoBehaviour
{
    public float raycastDistance = 1f; // 射线投射的距离

    private void Update()
    {
        // 获取玩家当前位置和朝向
        Vector2 playerPosition = transform.position;
        Vector2 playerDirection = transform.right;

        // 发射射线
        RaycastHit2D hit = Physics2D.Raycast(playerPosition, playerDirection, raycastDistance);

        // 判断是否击中方块
        if (hit.collider != null)
        {
            // 获取方块对象
            GameObject block = hit.collider.gameObject;

            // 处理方块逻辑，比如获取位置、颜色等信息，或者触发特定的事件
            Vector2 blockPosition = block.transform.position;
            Color blockColor = block.GetComponent<SpriteRenderer>().color;

            Debug.Log("Front block position: " + blockPosition);
            Debug.Log("Front block color: " + blockColor);
        }
    }
}
