`Destroy(collision.gameObject)` 是一个 Unity 脚本中的方法调用,它用于销毁与当前碰撞对象关联的游戏物体(`collision.gameObject`)。在游戏场景中,当某个对象(比如角色碰到一个带有"brick"标签的障碍物)发生碰撞时,如果这个碰撞检测到了预期的目标(例如砖块),则此行代码会删除碰撞目标,即摧毁该砖块,可能意味着减小分数、积分或影响后续的游戏状态。这样有助于实现游戏的物理规则或关卡设计逻辑。

这是一个在2D游戏中检测碰撞的函数。当游戏对象与另一个游戏对象发生碰撞时,该函数会被调用。在函数中,首先判断碰撞的游戏对象的标签是否为“GoldCoin”,如果是,则销毁该游戏对象,增加得分,并播放声音。如果不是,则停止播放声音。然后判断碰撞的游戏对象的标签是否为“zhi”,如果是,则销毁该游戏对象并减少血量。最后,如果碰撞的游戏对象的标签是“zhi2”,则忽略该碰撞。
public void Move() { int stt = sun; scoreText.text = stt.ToString(); if (Input.GetKey(KeyCode.W)) { direction = 0; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[2]; this.gameObject.transform.Translate(Vector3.up * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.S)) { this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[0]; direction = 2; this.gameObject.transform.Translate(Vector3.down * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.D)) { direction = 3; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[1]; this.gameObject.transform.Translate(Vector3.right * speed * Time.deltaTime); } else if (Input.GetKey(KeyCode.A)) { direction = 1; this.gameObject.GetComponent<SpriteRenderer>().sprite = prota[3]; this.gameObject.transform.Translate(Vector3.left * speed * Time.deltaTime); } // 播放脚步声 if (Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.D)) { if (!audioSource.isPlaying) { audioSource.clip = footstepSound; audioSource.loop = true; audioSource.Play(); } } else { audioSource.Stop(); } // 攻击 if (Input.GetMouseButtonDown(0)) { // 处理鼠标左键点击事件 GameObject ins = Instantiate(bulletPrefab); Vector2 clickPosition = Camera.main.ScreenToWorldPoint(Input.mousePosition); ins.GetComponent<Blogs>().clickPosition = clickPosition; if (direction == 0) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y + 0.15f); } else if (direction == 2) { ins.transform.position = new Vector3(this.gameObject.transform.position.x, this.gameObject.transform.position.y - 0.15f); } else if (direction == 3) { ins.transform.position = new Vector3(this.gameObject.transform.position.x + 0.15f, this.gameObject.transform.position.y); } else if (direction == 1) { ins.transform.position = new Vector3(this.gameObject.transform.position.x - 0.15f, this.gameObject.transform.position.y); } } }public void OnCollisionEnter2D(Collision2D collision) { if(collision.gameObject.tag == "GoldCoin") { Destroy(collision.gameObject); sun = sun + 1; if (!audioSource.isPlaying) { audioSource.clip = shique; audioSource.loop = true; audioSource.Play(); } } else { audioSource.Stop(); } //判断是否遭受攻击 if (collision.gameObject.tag == "zhi") { Destroy(collision.gameObject); hp = hp - 1; } // 检测碰撞物体的标签 if (collision.gameObject.tag == "zhi2") { // 忽略该碰撞 Physics2D.IgnoreCollision(collision.collider, GetComponent<Collider2D>()); } }
这段代码主要是一个角色的移动和攻击行为,使用了键盘和鼠标输入来响应玩家操作。角色可以向上、下、左、右移动,并且在移动时会播放脚步声音效。角色还可以使用鼠标左键攻击,发射一个子弹。如果角色与"GoldCoin"标签的游戏对象碰撞,就会增加分数,如果角色与"zhi"标签的游戏对象碰撞,就会减少血量。如果角色与"zhi2"标签的游戏对象碰撞,就会忽略该碰撞。
