Unity中實(shí)現(xiàn)坦克大戰(zhàn)——90版經(jīng)典游戲復(fù)刻
作者：呆呆的碼農(nóng)
工程難度：??
作為紅白機(jī)時(shí)代的經(jīng)典游戲，90坦克絕對(duì)算是年代表作品之一，今天我想用讀取配置表的方式復(fù)刻一下這兒時(shí)的經(jīng)典。
1.場(chǎng)景建設(shè)
首先將準(zhǔn)備好的場(chǎng)景素材導(dǎo)入工程，將其中的磚墻的Tag設(shè)置為Wall，草地Tag設(shè)置為Wall1，水墻設(shè)置為Wall2，鐵墻Wall3，并在每個(gè)物體身上添加Box Collider2D組件，設(shè)置三個(gè)空節(jié)點(diǎn)，用來掛載敵人和玩家和子彈。
上圖中白色圖片為敵人生成點(diǎn)。
2.數(shù)據(jù)配置表
作為可拓展、可配置的坦克大戰(zhàn)當(dāng)然離不開配置表的設(shè)置，你可以在配置表里面添加一切你想擁有的角色屬性或道具屬性等等。
玩家表分析設(shè)計(jì)：
1.需要一個(gè)唯一ID來區(qū)別表中的數(shù)據(jù)，方便索引；
2.需要等級(jí)來綁定顯示和子彈類型；
3.需要圖片名稱，用來加載圖片用；
4.需要子彈類型，用來顯示不同的子彈效果，及能打穿鐵墻和不能；
敵人表分析設(shè)計(jì)：
1.需要一個(gè)唯一ID來區(qū)別表中的數(shù)據(jù)，方便索引；
2.需要等級(jí)來綁定顯示和子彈類型；
3.需要圖片名稱，用來加載圖片；
4.需要子彈類型，用來顯示不同的子彈效果，及能打穿鐵墻和不能；
道具分析：
1.添加ID來，方便索引；
2.添加圖片名稱，用來顯示道具外形；
（勤勞的我，會(huì)告訴你就做了一個(gè)道具么？）
我的配置表如下：
1.玩家配置表
2.敵人配置表
3.道具配置表
做好表格之后需要將表格放入U(xiǎn)nity中讀取，這中間我用了一個(gè)小工具將.xlsx格式的文件轉(zhuǎn)化為TXT文本，并放在了Assets根目下，然后用Json插件讀取表格信息并寫入字典，當(dāng)游戲中需要對(duì)應(yīng)數(shù)據(jù)時(shí)new一個(gè)新的物體出來附上對(duì)應(yīng)的值，從而獲取動(dòng)態(tài)數(shù)據(jù)。代碼方式如下：
//構(gòu)造靜態(tài)數(shù)據(jù)類，他們的組成與表格對(duì)應(yīng)
public? class StaticMonsterData
{
??? public readonly string id;
??? public readonly string level;
??? public readonly string pictrue;
??? public readonly string buttle;
??? public float Value(string m)
??? {
??????? float? intA;
???? ???float .TryParse(m, out intA);
??????? return intA;
??? }
}
public class StaticPropData
{
??? public readonly string ID;
??? public readonly string Pictrue;
}
public class StaticCharacterData
{
??? public readonly string id;
??? public readonly string level;
??? public readonly string pictrue;
??? public readonly string buttle;
??? public float Value(string m)
??? {
??????? float intA;
??????? float .TryParse(m, out intA);
??????? return intA;
??? }
}
?
public class StaticData : MonoBehaviour {
??? public static StaticData Instance;
??? public Dictionary<string, StaticMonsterData> monsterDictionary;
??? public Dictionary<string, StaticCharacterData> characterDictionary;
??? public Dictionary<string, StaticPropData> propdictionary;
?
??? void Awake()
??? {
??????? Instance = this;
??????? Init();
??????? LoadSence();
??? }
??? // 初始化，將表格數(shù)據(jù)寫如字典
??? void Init()
??? {
??????? monsterDictionary = Load<Dictionary<string, StaticMonsterData>>("Monster");
??????? characterDictionary = Load<Dictionary<string, StaticCharacterData>>("Character");
??????? propdictionary = Load<Dictionary<string, StaticPropData>>("Prop");
??? }
?
??? // 載入場(chǎng)景，并掛載GameMode腳本
??? void LoadSence()
??? {
??????? var temp = Resources.Load<GameObject>("Sence").gameObject;
??????? var sence = Instantiate(temp);
??????? sence.name = temp.name;
??????? sence.AddComponent<GameMode>();
??? }
??? //獲取TXT文本并賦值給對(duì)應(yīng)的類，并返回T的類型值；
??? public static T Load<T>(string name)
??? {
??????? string rName = name;
??????? string readFilePath=? "Assets/" + rName + ".txt";
??????? string str;
??????? T data = default(T);
??????? if (File.Exists(readFilePath))
??????? {
??????????? StreamReader textData = File.OpenText(readFilePath);
??????????? str = textData.ReadLine();
??????????? textData.Close();
??????????? textData.Dispose();
??????????? data = JsonMapper.ToObject<T>(str);
??????? }
??????? return data;
??? }
?
}
?
?
動(dòng)態(tài)數(shù)據(jù)的獲取：
?
//建立角色類
public class RoleData
{
??? public string id;
??? public float? level;
??? public string picture;
??? public float? speed;
??? public float? bullet;
}
//玩家類繼承角色類
public class CharacterData : RoleData
{
??? ///建立構(gòu)造函數(shù)，獲取靜態(tài)數(shù)據(jù)
??? public static CharacterData GetCharacterData(StaticCharacterData data)
??? {
??????? CharacterData characterData = new CharacterData();
??????? characterData.id = data.id;
??????? characterData.level = data.Value(data.level);
??????? characterData.picture = data.pictrue;
??????? characterData.bullet = data.Value(data.buttle);
??????? return characterData;
??? }
}
?
public class MonsterData : RoleData
{
??? public static MonsterData GetMonsterData(StaticMonsterData data)
??? {
??????? MonsterData monsterData =new MonsterData();
??????? monsterData.id = data.id;
??????? monsterData.level = data.Value(data.level);
??????? monsterData.picture = data.pictrue;
??????? monsterData.bullet = data.Value(data.buttle);
??????? return monsterData;
??? }
}
?
public class PropData
{
??? public string id;
??? public string pictrue;
??? public static PropData GetPubicPropData(StaticPropData data)
??? {
?????? ?PropData propData = new PropData();
??????? propData.id = data.ID;
??????? propData.pictrue = data.Pictrue;
??????? return propData;
??? }
}
?
3.GameMode
當(dāng)數(shù)據(jù)獲取完畢，場(chǎng)景載入開始時(shí)，需要加載玩家角色，敵人角色，道具信息等，并將他們對(duì)應(yīng)的表信息轉(zhuǎn)換成能隨時(shí)調(diào)用的動(dòng)態(tài)信息賦值給他們。
代碼如下：
void Start()
??? {
??????? home = gameObject.transform.Find("CharacterHome").gameObject;
??????? home1 = gameObject.transform.Find("MonsterHome/Home1").gameObject;
??????? home2 =gameObject .transform .Find("MonsterHome/Home2").gameObject;
??????? home3 = gameObject.transform.Find("MonsterHome/Home3").gameObject;
??????? home4 = gameObject.transform.Find("MonsterHome/Home4").gameObject;
??????? animator1 = home1.GetComponent<Animator>();
??????? animator2 = home2.GetComponent<Animator>();
??????? animator3 = home3.GetComponent<Animator>();
??????? animator4 = home4.GetComponent<Animator>();
??????? Init();
??? }
?
???
??? void CreatMonster(string ID, GameObject Object)
??? {
??????? var Data = StaticData.Instance.monsterDictionary[ID];//獲取字典中相應(yīng)key值的靜態(tài)數(shù)據(jù)
??????? var monsterData = MonsterData.GetMonsterData(Data);//將靜態(tài)數(shù)據(jù)轉(zhuǎn)換成動(dòng)態(tài)數(shù)據(jù)
??????? var temp = Resources.Load<GameObject>("Monster");
??????? var monster = Instantiate(temp, Object.transform);
??????? monster.AddComponent<AiMonster>().data = monsterData;//將動(dòng)態(tài)數(shù)據(jù)賦值給角色。
??? }
??? //獲取KEY值為1的靜態(tài)數(shù)據(jù)，轉(zhuǎn)化賦值給生成的玩家。
??? void CreatCharacter()
??? {
??????? var Data = StaticData.Instance.characterDictionary["1"];
??????? var characterData = CharacterData.GetCharacterData(Data);
??????? var temp = Resources.Load<GameObject>("Character");
??????? var character = Instantiate(temp, home.transform);
??????? character.AddComponent<Character>().data = characterData;
??? }
??? //隨機(jī)地點(diǎn)生成道具。并賦值
??? void CreatProp()
??? {
??????? var data = StaticData.Instance.propdictionary["1"];
??????? var propData = PropData.GetPubicPropData(data);
??????? var temp = Resources.Load<GameObject>("Prop");
??????? var prop = Instantiate(temp,gameObject.transform);
??????? prop.transform.position += new Vector3(Random.Range(-480, 200),Random.Range(350,-350));
??????? prop.AddComponent<Prop>().data = propData;
??? }
??? void Init()
??? {
??????? animator1.Play("Start", 0);
??????? animator2.Play("Start", 0);
??????? animator3.Play("Start", 0);
??????? animator4.Play("Start", 0);
???????? //2s后創(chuàng)建敵人
??????? StartCoroutine(OnDelay(2.0f, () =>
???????? {
???????????? CreatMonster("1", home1);
???????? ????CreatMonster("2", home2);
???????????? CreatMonster("3", home3);
???????????? CreatMonster("4", home4);
???????? }));
??????? CreatCharacter();
??? }
??? int times = 0;
??? void Update ()
??? {
??????? if (isGameover == false)
??????? {
??????????? times++;
??????????? CreatProp();
??????????? if (times == 3)
??????????? {
??????????????? isGameover = true;
??????????? }
??????? }
??? }
??? IEnumerator OnDelay(float time, UnityEngine.Events.UnityAction rFunc)
??? {
??????? yield return new WaitForSeconds(time);
??????? rFunc();
??????? yield return null;
??? }
}
?

4.玩家
簡(jiǎn)單的搭建好玩家模型，設(shè)計(jì)玩家行為：
玩家可以上、下、左、右四個(gè)方向移動(dòng)；
每次移動(dòng)距離為場(chǎng)景中一個(gè)墻體的1/2寬度距離；
玩家無法穿越障礙；
玩家可以發(fā)射子彈；
玩家可以獲得道具；
玩家獲取道具升級(jí)之后可以改變外形和字典效果；
玩家可以死亡；

??????? bron = gameObject.transform.Find("Image").GetComponent<Image>();
???? ???//調(diào)用函數(shù)
??????? Init(data);
??????? OnPlayAnimation();
??? }
??? // 播放出生光圈，并在3S后隱藏該組件
??? private void OnPlayAnimation()
??? {
??????? animator.Play("Bron", 0);
??????? StartCoroutine(OnDelay(3, () =>
??????? {
??????????? bron.gameObject.SetActive(false);
??????? }));
??? }

5.敵人
搭建好敵人模型，設(shè)置敵人Ai：
敵人可以上、下、左、右四個(gè)方向移動(dòng)；
每次移動(dòng)距離為場(chǎng)景中墻的1/2寬；
敵人無法穿越障礙；若沒有遇見障礙則隨機(jī)選擇是否繼續(xù)延當(dāng)前方向前進(jìn)，若遇見障礙則隨機(jī)重新選擇移動(dòng)方向；
敵人可以發(fā)射子彈，頻率為1.5s一次；
敵人可以死亡；
代碼如下：
因?yàn)閿橙撕屯婕一纠淄皇前淹婕业妮斎霌Q成了隨機(jī)數(shù)，所以不貼代碼了。
查看效果:
6.道具
搭建好道具模型，設(shè)置其功能
道具隨機(jī)生成在地圖上；
玩家獲取道具后，道具消失；
因?yàn)橹挥幸粋€(gè)道具，模塊小沒有單獨(dú)劃分模塊出來隨機(jī)生成的體現(xiàn)在GamaMode腳本中體現(xiàn)，玩家獲取道具后消失在玩家功能中體現(xiàn)了。
嗯，90坦克的主要玩法差不多也就時(shí)這些了，而且所用的數(shù)據(jù)完全來至配置表，有興趣的朋友可以自己研拓展，可以增加一些道具啊，或者玩家屬性什么的，當(dāng)然也可以加別的那就看你的腦洞了。
