五、與遊戲世界互動

1、編寫一個簡單的滑鼠打飛碟（Hit UFO）遊戲

遊戲內容要求：

1.遊戲有 n 個 round，每個 round 都包括10 次 trial；
2.每個 trial 的飛碟的色彩、大小、發射位置、速度、角度、同時出現的個數都可能不同。它們由該 round 的 ruler 控制；
3.每個 trial 的飛碟有隨機性，總體難度隨 round 上升；
4.滑鼠點中得分，得分規則按色彩、大小、速度不同計算，規則可自由設定。

遊戲的要求：

  • 使用帶快取的工廠模式管理不同飛碟的生產與回收，該工廠必須是場景單例項的！ 具體實現見參考資源 Singleton 模板類
  • 近可能使用前面 MVC 結構實現人機互動與遊戲模型分離

設計過程

這次大部分的程式碼其實都可以沿用之前的，只需稍作修改就好。（那誰能想到被githubgank了呢）
在這裡插入圖片描述
主要改動的有：IUserAction；FirstController；ClickAction；CCActionManager，以及新增的有關UFO的指令碼。
IUserAction:很簡單，刪除幾個沒用的介面就好。

public interface IUserAction
{
	// void MoveBoat();
    // void MoveRole(RoleModel roleModel);
    void Restart();

    //void Check();
}

FirstController：FirstController涉及的改動較多，主要是UFO函式的呼叫，主體還是update，按輪次去產生或放出飛碟。（順手就把輪次變化實現了，他真不值得再建一個檔案）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class FirstController : MonoBehaviour, ISceneController, IUserAction {

	private bool isRuning;

	public UFOFactory ufoFactory;
	private int[] roundUFOs;
	private int score;
	private int round;
	private float sendTime;

	int sendCnt;
	// the first scripts
	void Awake () {
		SSDirector director = SSDirector.getInstance ();
		director.setFPS (60);
		director.currentSceneController = this;
		director.currentSceneController.LoadResources ();
		this.gameObject.AddComponent<UserGUI>();
        this.gameObject.AddComponent<CCActionManager>();
		ufoFactory=UFOFactory.getInstance();
		roundUFOs=new int[]{3,5,9,11,15};
		score=round=sendCnt=0;
		sendTime=0;
		sendCnt =0;
	}
	 
	// loading resources for the first scence
	public void LoadResources () {
		isRuning=true;
	}

	public void SendUFO(){
        GameObject ufo=ufoFactory.GetUFO(round);
        ufo.transform.position=new Vector3(-ufo.GetComponent<UFOData>().direction.x * 7, UnityEngine.Random.Range(0f, 8f), 0);
        ufo.SetActive(true);
        this.gameObject.GetComponent<CCActionManager>().Fly(ufo,ufo.GetComponent<UFOData>().speed,ufo.GetComponent<UFOData>().direction);
    }

	public bool GetIsRuning(){
		return isRuning;
	}

	public void JudgeCallback(bool isRuning,int score){
		this.score+=score;
        this.gameObject.GetComponent<UserGUI>().score=this.score;
        this.isRuning=isRuning;
    }

	public void Pause ()
	{
		throw new System.NotImplementedException ();
	}

	public void Resume ()
	{
		throw new System.NotImplementedException ();
	}

	#region IUserAction implementation
	public void Restart ()
	{
		isRuning=true;
		this.gameObject.GetComponent<UserGUI>().gameMessage="";
		this.gameObject.GetComponent<UserGUI>().score=0;
		score=round=sendCnt=0;
		sendTime=0;
		ufoFactory.FreeALL();
	}
	#endregion


	void Start () {

	}
	
	void Update () {

		
			sendTime+=Time.deltaTime;
			if(sendTime>2){
				sendTime=0;
				
				for(int i = 0; i < 5 && sendCnt < roundUFOs[round]; i++){
				  	sendCnt++;	
					SendUFO();
				}
				if(sendCnt == roundUFOs[round]&&round==roundUFOs.Length-1){
					isRuning=false;
					gameObject.GetComponent<UserGUI>().gameMessage = "Time Out!";
				}
				if(sendCnt == roundUFOs[round] && round < roundUFOs.Length - 1){
					sendCnt = 0;
                	round++;
				}
				
			
			}
			
	}

}

UFOFactory:涉及飛碟的生成與回收，它實現ClickAction的DealClick介面，在飛碟觸發點選事件之後，它就會獲得一定的分數。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UFOFactory : ClickAction
{
    private static UFOFactory _instance;

    public GameObject UFORed_Prefab;
    public GameObject UFOGreen_Prefab;
    public GameObject UFOBlue_Prefab;
    private List<UFOData> used;
    private List<UFOData> free;
    public FirstController controller;

    private UFOFactory(){
        used=new List<UFOData>();
        free=new List<UFOData>();
        UFORed_Prefab=GameObject.Instantiate<GameObject>(Resources.Load<GameObject>("UFORed"), Vector3.zero, Quaternion.identity);
        UFOGreen_Prefab=GameObject.Instantiate<GameObject>(Resources.Load<GameObject>("UFOGreen"), Vector3.zero, Quaternion.identity);
        UFOBlue_Prefab=GameObject.Instantiate<GameObject>(Resources.Load<GameObject>("UFOBlue"), Vector3.zero, Quaternion.identity);
        UFORed_Prefab.SetActive(false);
        UFOGreen_Prefab.SetActive(false);
        UFOBlue_Prefab.SetActive(false);
        controller=SSDirector.getInstance().currentSceneController as FirstController;
    }

    public static UFOFactory getInstance() {
		if (_instance == null) {
			_instance = new UFOFactory();
		}
		return _instance;
	}

    public GameObject GetUFO(int round){
        GameObject ufo;
        if(free.Count>0){
            ufo=free[0].gameObject;
            free.Remove(free[0]);
        }
        else{
            float kind=UnityEngine.Random.Range(0f,round+1);
            if(kind<0.5f){
                ufo=GameObject.Instantiate<GameObject>(UFOBlue_Prefab, Vector3.zero, Quaternion.identity);
                ufo.AddComponent<UFOData>();
                ufo.AddComponent<BoxCollider>();
                ufo.AddComponent<Click>();
                ufo.GetComponent<UFOData>().score=1;
            }
            else if(kind<2.5f){
                ufo=GameObject.Instantiate<GameObject>(UFOGreen_Prefab, Vector3.zero, Quaternion.identity);
                ufo.AddComponent<UFOData>();
                ufo.AddComponent<BoxCollider>();
                ufo.AddComponent<Click>();
                ufo.GetComponent<UFOData>().score=2;
            }
            else{
                ufo=GameObject.Instantiate<GameObject>(UFORed_Prefab, Vector3.zero, Quaternion.identity);
                ufo.AddComponent<UFOData>();
                ufo.AddComponent<BoxCollider>();
                ufo.AddComponent<Click>();
                ufo.GetComponent<UFOData>().score=3;
            }
            ufo.GetComponent<Click>().setClickAction(this);
        }
        ufo.GetComponent<UFOData>().direction=new Vector3(UnityEngine.Random.Range(-2f,2f),1,0);
        float level=UnityEngine.Random.Range(0f,round);
        if(level<3){
            ufo.GetComponent<UFOData>().speed=2.0f+round/6;
        }
        else if(level<6){
            ufo.GetComponent<UFOData>().speed=4.0f+round/6;
        }
        else{
            ufo.GetComponent<UFOData>().speed=5.0f+round/6;
        }
        level=UnityEngine.Random.Range(0f,round);
        if(level<3){
            ufo.GetComponent<UFOData>().scale=3;
            ufo.GetComponent<BoxCollider>().size=new Vector3(3f,2f,3f);
        }
        else if(level<6){
            ufo.GetComponent<UFOData>().scale=2;
            ufo.GetComponent<BoxCollider>().size=new Vector3(4f,3f,4f);
        }
        else{
            ufo.GetComponent<UFOData>().scale=1;
            ufo.GetComponent<BoxCollider>().size=new Vector3(5f,4f,5f);
        }
        used.Add(ufo.GetComponent<UFOData>());
        return ufo;
    }

    public void FreeUFO(GameObject ufo){
        foreach(UFOData ufoData in used){
            if(ufoData.gameObject.GetInstanceID()==ufo.GetInstanceID()){
                ufo.SetActive(false);
                free.Add(ufoData);
                used.Remove(ufoData);
                break;
            }
        }
    }

    public void FreeALL(){
        foreach(UFOData ufoData in used){
            ufoData.gameObject.SetActive(false);
            free.Add(ufoData);
            used.Remove(ufoData);
        }
        used.Clear();
    }

    public void DealClick(GameObject ufo){
        controller.JudgeCallback(true,ufo.GetComponent<UFOData>().score+(int)ufo.GetComponent<UFOData>().speed-3+ufo.GetComponent<UFOData>().scale-1);
        FreeUFO(ufo);
    }
}

CCFlyAction：這個還是比較關鍵的部分，控制飛碟的飛行。（不想它白給或者拉高人的血壓就多調調）

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CCFlyAction : SSAction
{
    float gravity;
    float speed;
    Vector3 direction;
    float time;

    public static CCFlyAction GetSSAction(Vector3 direction, float speed){
        CCFlyAction action = ScriptableObject.CreateInstance<CCFlyAction>();
        action.gravity = 9.8f;
        action.time = 0;
        action.speed = speed;
        action.direction = direction;
        return action;
    }

    public override void Start()
    {
        
    }

    public override void Update(){
        time+=Time.deltaTime;
        transform.Translate(Vector3.down*gravity*time*Time.deltaTime);
        transform.Translate(direction*speed*Time.deltaTime);
        if (this.transform.position.y<-8){
            this.destroy=true;
            this.enable=false;
            this.callback.SSActionEvent(this);
        }
    }
}

CCActionManager只是改改變數，實現好回撥函式就差不多了。
最後，改動UserGUI，加個計分板。ok！
UserGUI：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class UserGUI : MonoBehaviour {

	private IUserAction action;
	public string gameMessage;
	public int score;

	void Start () {
		action = SSDirector.getInstance ().currentSceneController as IUserAction;
		score=0;
	}

	void OnGUI() {  
		float width = Screen.width / 8;  
		float height = Screen.height / 13;

		//action.Check();
		GUIStyle style = new GUIStyle();
        style.normal.textColor = Color.red;
        style.fontSize = 30;
		GUIStyle style2 = new GUIStyle();
		style2.normal.textColor = Color.red;
		style2.fontSize = 50;
		GUI.Label(new Rect(340,200,50,200),gameMessage,style2);
		GUI.Label(new Rect(width*5, 0, width, height),"Your Score: ",style);
		GUI.Label(new Rect(width*7, 0, width, height),score.ToString(),style);
		if (GUI.Button(new Rect(0, 0, width, height), "Restart")) {  
			action.Restart();  
		} 

		string paused_title = SSDirector.getInstance ().Paused ? "Resume" : "Pause"; 
		if (GUI.Button(new Rect(width, 0, width, height), paused_title)) { 
			SSDirector.getInstance ().Paused = !SSDirector.getInstance ().Paused;
		} 
	}


}

效果展示視訊

在這裡插入圖片描述
發現可以通過暫停作弊，加個暫停不接受點選應該就好了

2、編寫一個簡單的自定義 Component （選做）

在這裡插入圖片描述
用了4個圓柱體，合成飛碟四不像
在這裡插入圖片描述

  • 將UFOData掛上去就可以附屬性了。
  • 當然通過GetComponent的方式也可以修改對相應的屬性。
