　　簡單說一下設計思路。對于飛碟的運動：運動學運動，有點類似牧師惡魔里面的過河；物理運動，則類似射箭小游戲的設計。所以，對于這兩種動作分別實現即可。
　　
運動學實現：

public void playDisk(GameObject disk){temp = disk;//隨機選取起始坐標float x = Random.Range(-1.5f, 1.5f);float z = Random.Range(-2f, 2f);Vector3 initialPos = new Vector3(x, -3.7f, z);disk.transform.position = initialPos;//隨機選取發射方向float xEnd = Random.Range(-2f, 2f);float yEnd = Random.Range(6f, 8f);float zEnd = Random.Range(0f, 5f);Vector3 dir = new Vector3(xEnd, yEnd, zEnd);//隨機設置速度float speed = Random.Range(10f,50f);action = MoveToAction.getAction(dir, speed);RunAction(disk, action, this);}//飛碟運動到指定地點后，添加重力，方便其落回地面public void actionDone(SSAction source){if(source == action){temp.GetComponent<Rigidbody>().useGravity = true;}}

物理學實現：

public void playDisk(GameObject disk) {//隨機選取起始坐標float x = Random.Range(-1.5f, 1.5f);float z = Random.Range(0f, 0.5f);Vector3 initialPos = new Vector3(x, -3.7f, z);disk.transform.position = initialPos;//隨機選取發射方向float xEnd = Random.Range(-2f, 2f);float yEnd = Random.Range(6f, 8f);float zEnd = Random.Range(0f, 5f);Vector3 dir = new Vector3(xEnd, yEnd, zEnd);disk.transform.up = dir;disk.GetComponent<Rigidbody>().velocity = dir * speed; //設置速度disk.GetComponent<Rigidbody>().useGravity = true;//Force = UnityEngine.Random.Range(-20, 20); //獲取隨機的風力 //disk.GetComponent<Rigidbody>().AddForce(new Vector3(Force, 0, 0), ForceMode.Force); }

接下來，實現飛碟兩種運動的組合：

public void EmitDisk() {if (count - leftTime == 2){count = leftTime;for(int i = 0; i < _diskNum; i++)//第一關，發射一個飛碟每次；第二關發射兩個飛碟每次{GameObject disk = factory.getDisk();//從飛碟工廠得到飛碟Debug.Log(disk);usedDisk.Add(disk);//飛碟進入場景disk.SetActive(true);disk.GetComponent<Renderer>().material.color = _color;disk.transform.localScale = _scale;if (mode == 1)iactionmanager.Normalplay(disk);//讓普通動作管理者設計軌跡elseiactionmanager.Physicplay(disk);//物理運動管理者設計}mode = 3 - mode;//更換下一次運動模式} }public class IActionManager : MonoBehaviour {public PhysicActionManager physicaction;public CCActionManager ccaction;void Awake(){physicaction = Singleton<PhysicActionManager>.Instance;ccaction = Singleton<CCActionManager>.Instance;}public void Normalplay(GameObject disk){ccaction.playDisk(disk);}public void Physicplay(GameObject disk){physicaction.playDisk(disk);} }

　　這樣，就完成了兩種運動的組合。接下來，就是計分。因為兩種運動，在其完成之前，我都添加了重力。所以，飛碟都會下落。因此，飛碟落地則會扣分；若未落地被擊中，則會得分：

public void RecycleDisk()//檢查需不需要回收飛碟 {for (int i = 0; i < usedDisk.Count; i++){if (usedDisk[i].activeInHierarchy == false ){if (usedDisk[i].transform.position.y <= -2)_judge.failAdisk();//失分usedDisk[i].GetComponent<Rigidbody>().useGravity = false;factory.free(usedDisk[i]);//讓飛碟工廠回收usedDisk.Remove(usedDisk[i]);//移除}} }public void shoot() {if (Input.GetMouseButtonDown(0) && (state == State.START || state == State.CONTINUE)){Debug.Log("shoot");Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);RaycastHit hit;if (Physics.Raycast(ray, out hit)){hit.transform.gameObject.SetActive(false);_judge.scoreADisk();//得分}} } //************************* void Update() {RecycleDisk(); }

　　接著，完善細節就可以完成整個游戲了。
