作業要求
編寫一個簡單的鼠標打飛碟(Hit UFO)遊戲
- 遊戲內容要求:
- 遊戲有 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;
- 每個 trial 的飛碟有隨機性,總體難度隨 round 上升;
- 鼠標點中得分,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:
- 使用帶緩存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實例的!具體實現見參考資源 Singleton 模板類
- 近可能使用前面 MVC 結構實現人機交互與遊戲模型分離
- 如果你的使用工廠有疑問,參考:彈藥和敵人:減少,重用和再利用

遊戲UML圖
這裏參考了前輩的代碼,所以UML類圖幾乎一樣,就直接借用了。
實現思路
這裏主要介紹幾個比較大的模塊的大概思路,詳細說明可見代碼的註釋部分。
- GUI頁面
首先是用戶GUI頁面
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class UserGUI : MonoBehaviour {
private FirstSceneController action;
private GUIStyle fontstyle1 = new GUIStyle();
//1
private GUIStyle textStyle;
private GUIStyle hintStyle;
private GUIStyle btnStyle;
//初始化
void Start () {
action = SSDirector.getInstance().currentSceneController as FirstSceneController;
fontstyle1.fontSize = 20;
}
// Update is called once per frame
private void OnGUI()
{
hintStyle = new GUIStyle {
fontSize = 20,
fontStyle = FontStyle.Normal
};
//標題
textStyle = new GUIStyle {
fontSize = 50,
alignment = TextAnchor.MiddleCenter
};
textStyle.normal.textColor = Color.blue;
GUI.Label(new Rect(Screen.width / 2 - 50, Screen.height / 2 - 150, 100, 50), "UFO小遊戲!", textStyle);
//button
btnStyle = new GUIStyle("button") {
fontSize = 15
};
btnStyle.normal.textColor = Color.black;
if (GUI.Button(new Rect(0, 50, 80, 50), "重新開始", btnStyle)) //前兩個參數是位置(左上角),後兩個是大小
{
action.Restart();
}
if (GUI.Button(new Rect(0, 100, 80, 50), " 暫停 ", btnStyle))
{
action.Pause();
}
//得分
if (action.flag == 0)
{
fontstyle1.normal.textColor = Color.red;
GUI.Label(new Rect(0, 0, 300, 50), "得分: " +
action.score + ", 回合: " + (Mathf.CeilToInt(FirstSceneController.times / 10) + 1), fontstyle1);
}
//結束
else if (action.flag == 1)
{
fontstyle1.normal.textColor = Color.red;
GUI.Label(new Rect(0, 0, 300, 50), "你的得分是 : " + action.score, fontstyle1);
}
//暫停
else
{
fontstyle1.normal.textColor = Color.green;
GUI.Label(new Rect(0, 0, 300, 50), "得分: " +
action.score + ", 回合: " + (Mathf.CeilToInt(FirstSceneController.times / 10) + 1), fontstyle1);
GUI.Label(new Rect(Screen.width / 2 - 150, Screen.height/2-50, 300, 100), "暫停!", textStyle);
}
}
}
- 由之前的兩次作業(牧師和魔鬼),我們已經有了一個較爲完整的MVC框架,所以這裏可以直接套用的之前的框架。但這裏比較特別的是,添加了一個飛碟工廠,用於減少資源開銷 ,詳細說明請見註釋:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DiskFactory : MonoBehaviour {
//used和free分別表示已經在使用的和未被利用的飛碟對象
public List<GameObject> used = new List<GameObject>();
public List<GameObject> free = new List<GameObject>();
//初始化
void Start () { }
public void GenDisk()
{
GameObject disk;
//如果free的列表爲空,而我們有需要它,這時才創建新的對象
if(free.Count == 0)
{
disk = Instantiate<GameObject>(Resources.Load<GameObject>("Prefabs/Disk"), Vector3.zero, Quaternion.identity);
}
//不然,就用之前的
else
{
disk = free[0];
free.RemoveAt(0);
}
float x = Random.Range(-10.0f, 10.0f);
disk.transform.position = new Vector3(x, 0, 0);
disk.transform.Rotate(new Vector3(x < 0? -x*9 : x*9, 0, 0));
float r = Random.Range(0f, 1f);
float g = Random.Range(0f, 1f);
float b = Random.Range(0f, 1f);
Color color = new Color(r, g, b);
disk.transform.GetComponent<Renderer>().material.color = color;
used.Add(disk);
}
public void RecycleDisk(GameObject obj)
{
obj.transform.position = Vector3.zero;
free.Add(obj);
}
}
- 場景控制器,依靠之前所做的MVC架構的分離作用,這裏僅需要改Awake,Update,GenGameObject這三個函數和各種變量。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
//場景控制器
public class CCActionManager : SSActionManager, ISSActionCallback
{
//這裏將動作變成一個列表,就能夠同時控制多個飛碟在遊戲中飛行
public FirstSceneController sceneController;
public List<CCMoveToAction> seq = new List<CCMoveToAction>();
public UserClickAction userClickAction;
public DiskFactory disks;
protected new void Start()
{
sceneController = (FirstSceneController)SSDirector.getInstance().currentSceneController;
sceneController.actionManager = this;
disks = Singleton<DiskFactory>.Instance;
}
protected new void Update()
{
if(disks.used.Count > 0)
{
GameObject disk = disks.used[0];
float x = Random.Range(-10, 10);
CCMoveToAction moveToAction = CCMoveToAction.GetSSAction(new Vector3(x, 12, 0), 3 * (Mathf.CeilToInt(FirstSceneController.times / 10) + 1) * Time.deltaTime);
seq.Add(moveToAction);
this.RunAction(disk, moveToAction, this);
disks.used.RemoveAt(0);
}
if (Input.GetMouseButtonDown(0) && sceneController.flag == 0)
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hitGameObject;
if (Physics.Raycast(ray, out hitGameObject))
{
GameObject gameObject = hitGameObject.collider.gameObject;
if (gameObject.tag == "disk")
{
foreach(var k in seq)
{
if (k.gameObject == gameObject)
k.transform.position = k.target;
}
userClickAction = UserClickAction.GetSSAction();
this.RunAction(gameObject, userClickAction, this);
}
}
}
base.Update();
}
public void SSActionEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
{
disks.RecycleDisk(source.gameObject);
seq.Remove(source as CCMoveToAction);
source.destory = true;
if (FirstSceneController.times >= 30)
sceneController.flag = 1;
}
public void CheckEvent(SSAction source, SSActionEventType events = SSActionEventType.Completed, int intParam = 0, string strParam = null, Object objParam = null)
{
}
public void Pause()
{
if(sceneController.flag == 0)
{
foreach (var k in seq)
{
k.enable = false;
}
sceneController.flag = 2;
}
else if(sceneController.flag == 2)
{
foreach (var k in seq)
{
k.enable = true;
}
sceneController.flag = 0;
}
}
}
