Unity 见缝插针

Unity零基础入门 - 见缝插针（Unity2017）

UML流程

靶子旋转 RotateSelf

public class RotateSelf : MonoBehaviour {public float speed = 90;// Update is called once per framevoid Update () {transform.Rotate(new Vector3(0, 0, -speed * Time.deltaTime));}
}

// Vector3(x,y,z)对应(红，绿，蓝)

//旋转修改z，像塑料小陀螺的小柄

针头 PinHead

//触发检测，调用游戏结束的方法

public class PinHead : MonoBehaviour {private void OnTriggerEnter2D(Collider2D collision){if (collision.tag == "PinHead"){GameObject.Find("GameManager").GetComponent<GameManager>().GameOver();}}
} 

针 预制体 Pin

游戏控制器 GameManager

(了解) GetActiveScene

GetActiveScene().buildIndex);//得到当前激活的场景
Unity3D_(API)场景切换SceneManager

游戏管理者 GamaManager

代码

public class GameManager : MonoBehaviour {[Tooltip("这里没用到，1号针的起飞位置")] private Transform startPoint;[Tooltip("2号针的预备位置，也是生成位置")]   private Transform spawnPoint;[Tooltip("鼠标点击就起飞，1号针")]   private Pin currentPin;[Tooltip("数量、分数")] private int score = 0;[Tooltip("靶子中间的文本框")] public Text scoreText;[Tooltip("针预制体")] public GameObject pinPrefab;//[Tooltip("失败？")] private bool isGameOver = false;[Tooltip("主相机")] private Camera mainCamera;[Tooltip("游戏结束的动画的时长")] public float gameOverAnimationTime = 3;[Tooltip("游戏结束，相机最终大小")] public float cameraOrthographicSizeWhenGameOver = 4f;// Use this for initializationvoid Start () {startPoint = GameObject.Find("StartPoint").transform;//取spawnPoint = GameObject.Find("SpawnPoint").transform;mainCamera = Camera.main;SpawnPin();//实例针}private void Update(){if (isGameOver) return;if (Input.GetMouseButtonDown(0)){score++;//这逻辑是射出去就有分scoreText.text = score.ToString();//UI更新currentPin.StartFly();//1号起飞SpawnPin();//2号预备}}void SpawnPin()//生产针{Vector3 position = spawnPoint.position;Quaternion quaternion = pinPrefab.transform.rotation;//头朝下//GameObject.Instantiate(预制体,位置,旋转角度);currentPin = Instantiate(pinPrefab, position, quaternion ).GetComponent<Pin>();}public void GameOver()//游戏结束{if (isGameOver) return;//暂时未发现不加的后果//GameObject.Find("Circle").GetComponent<RotateSelf>().enabled = false;//不转了。单例浪费，所以或者拖拽StartCoroutine(GameOverAnimation()); //开协程，调用方法isGameOver = true;}IEnumerator GameOverAnimation()//游戏结束的动画{while (true){float size = cameraOrthographicSizeWhenGameOver;//嫌字多//变色、变大mainCamera.backgroundColor = Color.Lerp(mainCamera.backgroundColor, Color.red, gameOverAnimationTime * Time.deltaTime);mainCamera.orthographicSize = Mathf.Lerp(mainCamera.orthographicSize, size, gameOverAnimationTime * Time.deltaTime);if( Mathf.Abs( mainCamera.orthographicSize- size )<0.01f){break;}yield return 0;}yield return new WaitForSeconds(0.2f);//等待n秒后，加载新游戏SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);//重新加载当前激活的场景}
}

游戏结束

//旁边的Text是用来测试rtotateSelf的，因为觉得针跟着靶子转很神奇（结果是设置父节点的原因）

针 Pin

代码

public class Pin : MonoBehaviour {[Tooltip("针的飞行速度")] public float speed = 5;[Tooltip("起飞？")] private bool isFly = false;[Tooltip("靶上？")] private bool isReach = false;[Tooltip("1号针起飞位置")] private Transform startPoint;[Tooltip("针扎上靶子时针的位置")]    private Vector3 pinReachPos;[Tooltip("靶子")]   private Transform circle;// Use this for initializationvoid Start () {startPoint = GameObject.Find("StartPoint").transform;circle = GameObject.FindGameObjectWithTag("Circle").transform;//circle = GameObject.Find("Circle").transform;////pinReachPos = circle.position;pinReachPos.y -= 1.55f;}// Update is called once per framevoid Update () {if (isFly == true)//1号针飞{transform.position = Vector3.MoveTowards(transform.position, pinReachPos, speed * Time.deltaTime);if (Vector3.Distance(transform.position, pinReachPos) < 0.05f)//差不多就得了，卡==0有时检测不到{transform.position = pinReachPos;transform.parent = circle;//以此让针跟着靶子旋转isFly = false;}}else//2号针上位{if (isReach == false){transform.position = Vector3.MoveTowards(transform.position, startPoint.position, speed * Time.deltaTime);if (Vector3.Distance(transform.position, startPoint.position) < 0.05f)//也是差不多得了{isReach = true;}}}}public void StartFly()//鼠标左键调用GameManager,GameManager调用StartFly(){isFly = true;isReach = true;}
}
