Unity【入门】小项目坦克大战

1、开始场景

1、场景装饰

RotateObj

using UnityEngine;public class RotateObj : MonoBehaviour
{public float rotateSpeed = 15;void Update(){transform.Rotate(Vector3.up, rotateSpeed * Time.deltaTime);}
}

2、开始界面

BasePanel

using UnityEngine;public class BasePanel<T> : MonoBehaviour where T:class
{//两个关键的静态成员//私有的静态成员变量（声明） 基础Mono不能newprivate static T instance;//公共的静态成员属性或方法（获取）//public static T Instance//{//    get//    {//        return instance;//    }//}public static T Instance => instance;//instance赋值，为确保挂载的唯一性，自己定义一个规范private void Awake(){instance = this as T;}public virtual void ShowMe(){this.gameObject.SetActive(true);}public virtual void HideMe(){this.gameObject.SetActive(false);}
}

BeginPanel

using UnityEngine;
using UnityEngine.SceneManagement;
/// <summary>
/// 通过类名快速得到脚本
/// </summary>
public class BeginPanel : BasePanel<BeginPanel>
{// 声明公共的成员变量来关联各个控件public CustomGUIButton btnBegin;public CustomGUIButton btnSetting;public CustomGUIButton btnQuit;public CustomGUIButton btnRank;void Start(){//锁定鼠标在窗口内//Cursor.lockState = CursorLockMode.Confined;//监听一次按钮点击过后的内容btnBegin.clickEvent += () => {SceneManager.LoadScene("GameScene");};btnSetting.clickEvent += () =>{SettingPanel.Instance.ShowMe();HideMe();};btnQuit.clickEvent += () =>{Application.Quit();};btnRank.clickEvent += () =>{RankPanel.Instance.ShowMe();Instance.HideMe();};}
}

3、设置界面

GameDataMgr

/// <summary>
/// 游戏数据管理类，是一个单例模式对象
/// </summary>
public class GameDataMgr
{private static GameDataMgr instance = new GameDataMgr();public static GameDataMgr Instance { get => instance; }//设置信息对象public MusicData musicData;//排行榜数据对象public RankList rankData;private GameDataMgr(){//初始化游戏数据musicData = PlayerPrefsDataMgr.Instance.LoadData(typeof(MusicData), "Music_Key") as MusicData;//第一次进入游戏的默认值if (!musicData.notFirst){musicData.notFirst = true;musicData.isOpenBK = true;musicData.isOpenSound = true;musicData.bkValue = 1;musicData.soundValue = 1;PlayerPrefsDataMgr.Instance.SaveData(musicData, "Music_Key");}//初始化读取排行榜数据rankData = PlayerPrefsDataMgr.Instance.LoadData(typeof(RankList),"Rank_key") as RankList;}//提供一个添加数据到排行榜中的方法public void AddRankInfo(string name,int score,float time){rankData.list.Add(new RankInfo(name,score,time));//排序rankData.list.Sort((a, b) => a.time < b.time ? -1 : 1);//移除第10条之后的数据for (int i = rankData.list.Count-1; i >= 10; i--){rankData.list.RemoveAt(i);}//存储PlayerPrefsDataMgr.Instance.SaveData(rankData, "Rank_key");}public void OpenOrCloseBKMusic(bool isOpen){musicData.isOpenBK = isOpen; //改变是否开启状态//控制开关BKMusic.Instance.ChangeOpen(isOpen);PlayerPrefsDataMgr.Instance.SaveData(musicData, "Music_Key"); //存储}public void OpenOrCloseSound(bool isOpen){musicData.isOpenSound = isOpen; //改变PlayerPrefsDataMgr.Instance.SaveData(musicData, "Music_Key"); //存储}public void ChangeBKValue(float value){musicData.bkValue = value;BKMusic.Instance.ChangeValue(value);PlayerPrefsDataMgr.Instance.SaveData(musicData, "Music_Key");}public void ChangeSoundValue(float value){musicData.soundValue = value;PlayerPrefsDataMgr.Instance.SaveData(musicData, "Music_Key");}
}

SettingPanel

using UnityEngine;
using UnityEngine.SceneManagement;public class SettingPanel : BasePanel<SettingPanel>
{//声明成员变量 关联控件public CustomGUISlider sliderMusic;public CustomGUISlider sliderSound;public CustomGUIToggle togMusic;public CustomGUIToggle togSound;public CustomGUIButton btnClose;void Start(){//监听对应的事件，处理逻辑sliderMusic.changeValue += (value) => GameDataMgr.Instance.ChangeBKValue(value);sliderSound.changeValue += (value) => GameDataMgr.Instance.ChangeSoundValue(value);togMusic.changeValue += (value) => GameDataMgr.Instance.OpenOrCloseBKMusic(value);togSound.changeValue += (value) => GameDataMgr.Instance.OpenOrCloseSound(value);btnClose.clickEvent += () =>{HideMe();//判断当前所在场景if(SceneManager.GetActiveScene().name == "BeginScene")//把隐藏的开始界面重新显示BeginPanel.Instance.ShowMe();};HideMe();//this.gameObject.SetActive(false);}public void UpdatePanelInfo(){//更新设置信息MusicData data = GameDataMgr.Instance.musicData;sliderMusic.nowValue = data.bkValue;sliderSound.nowValue = data.soundValue;togMusic.isSel = data.isOpenBK;togSound.isSel = data.isOpenSound;}public override void ShowMe(){base.ShowMe();UpdatePanelInfo(); //更新设置信息}public override void HideMe(){base.HideMe();Time.timeScale = 1;}
}

4、音效数据逻辑

MusicData

/// <summary>
/// 音效数据类，用于存储音乐设置相关的信息
/// </summary>
public class MusicData
{//背景音乐public bool isOpenBK;//音效public bool isOpenSound;public float bkValue;public float soundValue;public bool notFirst;
}

5、排行榜界面

RankPanel

using System.Collections.Generic;public class RankPanel : BasePanel<RankPanel>
{//关联public的控件对象public CustomGUIButton btnClose;private List<CustomGUILable> labRank = new List<CustomGUILable>();private List<CustomGUILable> labPlayer = new List<CustomGUILable>();private List<CustomGUILable> labScore = new List<CustomGUILable>();private List<CustomGUILable> labTime = new List<CustomGUILable>();void Start(){for (int i = 1; i <= 10; i++){//通过路径/找到子对象的子对象//labRank.Add(transform.Find("labRank/labRank" + i).GetComponent<CustomGUILable>());labPlayer.Add(transform.Find("labPlayer/labPlayer" + i).GetComponent<CustomGUILable>());labScore.Add(transform.Find("labScore/labScore" + i).GetComponent<CustomGUILable>());labTime.Add(transform.Find("labTime/labTime" + i).GetComponent<CustomGUILable>());}//print("排名" + labRank.Count);print("玩家" + labPlayer.Count);print("分数" + labScore.Count);print("通关时间" + labTime.Count);//处理事件监听逻辑btnClose.clickEvent += () =>{HideMe();BeginPanel.Instance.ShowMe();};//GameDataMgr.Instance.AddRankInfo("测试", 100, 7232);HideMe();}public override void ShowMe(){base.ShowMe();UpdatePanelInfo();}public void UpdatePanelInfo(){//处理根据排行榜数据更新面板//获取GameDataMgr中的排行榜列表，用于更新List<RankInfo> list = GameDataMgr.Instance.rankData.list;//根据列表更新面板数据for (int i = 0; i < list.Count; i++){labPlayer[i].content.text = list[i].name;labScore[i].content.text = list[i].score.ToString();int time = (int)list[i].time;labTime[i].content.text = "";if (time / 3600 > 0){labTime[i].content.text += time / 3600 + "时";}if (time % 3600 / 60 > 0 || labTime[i].content.text != ""){labTime[i].content.text += time % 3600 / 60 + "分";}labTime[i].content.text += time % 60 + "秒";}}
}

6、排行榜数据逻辑

RankInfo

using System.Collections.Generic;/// <summary>
/// 排行榜单条数据
/// </summary>
public class RankInfo
{public string name;public int score;public float time;public RankInfo() { }public RankInfo(string name, int score, float time){this.name = name;this.score = score;this.time = time;}
}
/// <summary>
/// 排行榜列表
/// </summary>
public class RankList
{public List<RankInfo> list;
}

7、背景音乐

BKMusic

using UnityEngine;public class BKMusic : MonoBehaviour
{private static BKMusic instance;public static BKMusic Instance => instance;public AudioSource audioSource;void Awake(){//初始化 赋值instance = this;//得到自己依附的游戏对象上挂载的音频源脚本audioSource = GetComponent<AudioSource>();//初始化已经设置好的信息ChangeValue(GameDataMgr.Instance.musicData.bkValue);ChangeOpen(GameDataMgr.Instance.musicData.isOpenBK);}/// <summary>/// 改变背景音乐大小/// </summary>/// <param name="value"></param>public void ChangeValue(float value){audioSource.volume = value;}/// <summary>/// 开启背景音乐/// </summary>/// <param name="isOpen"></param>public void ChangeOpen(bool isOpen){//关闭 mute（静音）audioSource.mute = !isOpen;}
