要求

• 游戲有 n 個 round，每個 round 都包括10 次 trial；
• 每個 trial 的飛碟的色彩、大小、發(fā)射位置、速度、角度、同時出現(xiàn)的個數(shù)都可能不同。它們由該 round 的 ruler 控制；
• 每個 trial 的飛碟有隨機性，總體難度隨 round 上升；
• 鼠標(biāo)點中得分，得分規(guī)則按色彩、大小、速度不同計算，規(guī)則可自由設(shè)定
• 使用帶緩存的工廠模式管理不同飛碟的生產(chǎn)與回收，該工廠必須是場景單實例的
• 近可能使用前面 MVC 結(jié)構(gòu)實現(xiàn)人機交互與游戲模型分離
  工廠模式:

工廠模式:飛碟工廠的設(shè)計模式是單實例的工廠,分?jǐn)?shù)和場景控制及各種預(yù)制的分離和使用

游戲規(guī)則

• 每個回合60s，玩過3關(guān)之后勝利
• 飛碟不同的顏色，大小對應(yīng)不同的分?jǐn)?shù)
• 回合60s內(nèi)達到500分進入下一關(guān)，不能達到500分則失敗

游戲?qū)崿F(xiàn)

代碼結(jié)構(gòu)

導(dǎo)演類

public class SSDirector : System.Object {public static SSDirector _instance;public ISceneController currentScenceController { get; set; }public bool running { get; set; }public static SSDirector getInstance(){if (_instance == null){_instance = new SSDirector();}return _instance;}public int getFPS(){return Application.targetFrameRate;}public void setFPS(int fps){Application.targetFrameRate = fps;}public void NextScene(){Debug.Log("no next scene");} }

飛碟工廠

工廠里面實現(xiàn)功能:GetDisk()和FreeDisk()

飛碟工廠類，在場景控制器需要某種飛碟的時候，飛碟工廠從倉庫(List free)中獲取這種飛碟，如果倉庫中沒有，則實例化一個新飛碟，然后添加used list 中
當(dāng)場景控制器發(fā)現(xiàn)飛碟被打中或者飛碟掉出攝像機視野外，將執(zhí)行回收飛碟,在used list 刪除飛碟，然后將該飛碟的數(shù)據(jù)添加到free_list中循環(huán)利用

• 偽代碼設(shè)計

GetDisk() IF (free list has disk) THEN a_disk = remove one from list ELSE a_disk = clone from Prefabs ENDIF Set Disk_Data of a_disk with the ruler Add a_disk to used list Return a_disk FreeDisk() Find disk in used list IF (not found) THEN Remove exception Move disk from used to free list

• 代碼實現(xiàn)

public class DiskFactory : MonoBehaviour {private List<GameObject> used = new List<GameObject>();private List<GameObject> free = new List<GameObject>();private Color[] color = { Color.red, Color.green, Color.blue, Color.yellow };public GameObject GetDisk(int ruler){GameObject a_disk;if (free.Count > 0){a_disk = free[0];free.Remove(free[0]);}else{a_disk = GameObject.Instantiate(Resources.Load("prefabs/Disk")) as GameObject;Debug.Log(a_disk);}a_disk.GetComponent<DiskData>().size = UnityEngine.Random.Range(0, 7-ruler);a_disk.GetComponent<DiskData>().color = color[UnityEngine.Random.Range(0, 4)];a_disk.GetComponent<DiskData>().speed = UnityEngine.Random.Range(5+ruler, 8+ruler);a_disk.transform.localScale = new Vector3(a_disk.GetComponent<DiskData>().size * 2, a_disk.GetComponent<DiskData>().size * 0.1f, a_disk.GetComponent<DiskData>().size * 2);a_disk.GetComponent<Renderer>().material.color = a_disk.GetComponent<DiskData>().color;a_disk.SetActive(true);used.Add(a_disk);return a_disk;}public void FreeDisk(GameObject disk){for(int i = 0; i < used.Count; i++){if(used[i] == disk){disk.SetActive(false);used.Remove(used[i]);free.Add(disk);}}} }

• 飛碟數(shù)據(jù)由round的ruler控制

a_disk.GetComponent<DiskData>().size = UnityEngine.Random.Range(0, 7-ruler); a_disk.GetComponent<DiskData>().color = color[UnityEngine.Random.Range(0, 4)]; a_disk.GetComponent<DiskData>().speed = UnityEngine.Random.Range(10+ruler, +ruler);

場景控制類

• 場景單實例,運用模板，可以為每個 MonoBehaviour子類 創(chuàng)建一個對象的實例

public class Singleton<T> where T : MonoBehaviour {private static T instance;public static T Instance{get{if (instance == null){instance = (T)Object.FindObjectOfType(typeof(T));if (instance == null){Debug.LogError("Can't find instance of " + typeof(T));}}return instance;}} }

• 射擊條件

public void shoot() {if (Input.GetMouseButtonDown(0) && (state == State.START || state ==State.CONTINUE)){Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hit;if (Physics.Raycast(ray, out hit)){if ((SSDirector.getInstance().currentScenceController.state ==State.START || SSDirector.getInstance().currentScenceController.state== State.CONTINUE)){shootAtSth = hit.transform.gameObject;explosion.transform.position =hit.collider.gameObject.transform.position;explosion.GetComponent<Renderer>().material =hit.collider.gameObject.GetComponent<Renderer>().material;explosion.GetComponent<ParticleSystem>().Play();}}} }

• 加載飛碟,從飛碟工廠得到飛碟并將飛碟加入場景
• 檢查飛碟是否需要回收
• 判斷游戲狀態(tài)

public void Judge(){if(shootAtSth != null && shootAtSth.transform.tag == "Disk" && shootAtSth.activeInHierarchy){scoreRecorder.Record(shootAtSth);diskFactory.FreeDisk(shootAtSth);shootAtSth = null;}if(scoreRecorder.getScore() > 500 * round){round++;leaveSeconds = count = 60;}if (round == 4) {StopAllCoroutines();state = State.WIN;}else if (leaveSeconds == 0 && scoreRecorder.getScore() < 500 * round) {StopAllCoroutines();state = State.LOSE;} elsestate = State.CONTINUE;}

動作管理類

public class RoundActionManager : SSActionManager, ISSActionCallback {public RoundController scene;public MoveToAction action1, action2;public SequenceAction saction;float speed;public void addRandomAction(GameObject gameObj){int[] X = { -20, 20 };int[] Y = { -5, 5 };int[] Z = { -20, -20 };Vector3 starttPos = new Vector3(UnityEngine.Random.Range(-20, 20),UnityEngine.Random.Range(-5, 5),UnityEngine.Random.Range(50, 10));gameObj.transform.position = starttPos;Vector3 randomTarget = new Vector3(X[UnityEngine.Random.Range(0, 2)],Y[UnityEngine.Random.Range(0, 2)],Z[UnityEngine.Random.Range(0, 2)]);MoveToAction action = MoveToAction.getAction(randomTarget, gameObj.GetComponent<DiskData>().speed);RunAction(gameObj, action, this);}protected void Start(){scene = (RoundController)SSDirector.getInstance().currentScenceController;scene.actionManager = this;}protected new void Update(){base.Update();}public void actionDone(SSAction source){Debug.Log("Done");} }

UI實現(xiàn)

代碼詳見/asset/script/UserGUI.cs

積分規(guī)則

飛碟速度越快,體積越小,得到的分?jǐn)?shù)就越高,不同顏色的飛碟得分情況的也不同

public class ScoreRecorder : MonoBehaviour {private float score;public float getScore(){return score;}public void Record(GameObject disk){score += (100 - disk.GetComponent<DiskData>().size *(20 - disk.GetComponent<DiskData>().speed));Color c = disk.GetComponent<DiskData>().color;switch (c.ToString()){case "red":score += 250;break;case "green":score += 200;break;case "blue":score += 150;break;case "yellow":score += 100;break;}}
