今天又挤出一点时间来，继续写一下那个项目的内容，关于这个商店系统，在这个游戏中，实现了简单的轮胎兑换金币，也是用到了unity自带的数据库，真心好用呢，下面就详细说一下；
首先呢，轮胎哪来的呢，就是在游戏中我们的猪脚在躲避障碍的同时在收集轮胎，没一局的金币数量都可以累计，用的就是数据库呢，这样，我们在游戏轮胎数量显示的地方添加纪录游戏轮胎数增加的语句，
GUI.Label(new Rect(Screen.width * 0.85f, Screen.height * 0.01f, 0, 0), Mathf.Round(TotalDistance).ToString() + " M",bb); //Place the distance count on the top right of the screen
GUI.DrawTexture(new Rect(Screen.width * 0.90f, Screen.height * 0.15f, Screen.width * 0.07f, Screen.width * 0.07f), Gems); //Place the gem image beside the gems count on the top right of the screen
GUI.Label(new Rect(Screen.width * 0.85f, Screen.height * 0.17f, 0f, 0f), m_player.m_score.ToString(),bb); //Place the gems count on the top right of the screen
quanju.lun = m_player.m_score;
这一句quanju.lun = m_player.m_score;用的是全局变量，把轮胎的个数记录在全局变量中，这样不管在哪个脚本中，我们都可以使用这个变量了，不错吧，没有看到数据库的语句吧，我也没看到，再找找，再另一个脚本呢，我的End脚本，之前专家说游戏没有结束，这样一来增加了end游戏实现了结束模块，看一下代码吧
using UnityEngine;
using System.Collections;
public class End : MonoBehaviour
{
//This script handles the leveling up in the game and the score and distance records. In each level up the value ranges for platforms are changed ( platform length/height/width/rotate etc )
protected mishuzengjia m_player;
internal GameObject Player; //Used to hold the player object, if it's in the scene
public GUISkin GUIskin; //The skin gui we'll use
internal float TotalDistance = 0; //The total distance passed by the player
public Texture2D Gems;
public Texture2D img;
public AudioClip CrashSound;
private AudioSource _audioSource;
//public int right = 1;
public GUISkin GUIskin2;
//public Texture2D Stop;
//public int stop = 1;
//public int jieshu;
void Awake()
{
_audioSource = this.gameObject.AddComponent<AudioSource>();
_audioSource.loop = false;
_audioSource.volume = 1.0f;
_audioSource.pitch = 1.0f;
}
void Start()
{
Player = GameObject.FindWithTag("Player"); //Find the player in the scene and put it in a variable, for later use
_audioSource.PlayOneShot(CrashSound);
GameObject obj = GameObject.FindGameObjectWithTag("Player");
if (obj != null)
{
m_player = obj.GetComponent<mishuzengjia>();
}
}
//public void EndLevel()
//{
// PlayerPrefs.SetInt("TotalDistance", (int)TotalDistance); //Put the value of TotalDistance in a playerPref record which will keep this value even after going to a different level or even quitting the game
// StartCoroutine(WaitAndDelay(2.0f));
// Application.LoadLevel("end"); //Load the end screenm, which has total score displayed and a menu
//}
//IEnumerator WaitAndDelay(float waitTime)
//{
// yield return new WaitForSeconds(waitTime);
//}
void OnGUI()
{
//The skin gui we'll use
//GUIStyle aa = new GUIStyle();
//aa.fontSize = 40;
//aa.normal.textColor = new Color(255, 255, 255);
GUI.DrawTexture(new Rect(0, 0, Screen.width, Screen.height), img);
GUI.skin = GUIskin;
GUIStyle bb1 = new GUIStyle();
bb1.fontSize = 40;
bb1.normal.textColor = new Color(0, 0, 0);
GUI.Label(new Rect(Screen.width * 0.4f, Screen.height * 0.25f, 0, 0),"最终距离 : "+ quanju.mishu.ToString() + " M", bb1);
GUI.DrawTexture(new Rect(Screen.width * 0.64f, Screen.height * 0.34f, Screen.width * 0.07f, Screen.width * 0.07f), Gems); //Place the gem image beside the gems count on the top right of the screen
GUI.Label(new Rect(Screen.width * 0.4f, Screen.height * 0.4f, 0f, 0f), "收集轮胎 : "+quanju.lun.ToString(), bb1);
//GUI.Label(new Rect(Screen.width * 0.5f + 160, Screen.height * 0.3f, 0, 0), "恭喜获得四枚玲珑轮胎");
GUI.Label(new Rect(Screen.width * 0.5f, Screen.height * 0.5f, 0, 0), "游戏结束", bb1);
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
quanju.LunTotal = PlayerPrefs.GetInt("LunTai");
//Time.timeScale = 0;
GUI.skin = GUIskin2;
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.6f, Screen.width * 0.2f, Screen.height * 0.1f), "再试一次"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Time.timeScale = 1;
Application.LoadLevel("choose");
}
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.8f, Screen.width * 0.2f, Screen.height * 0.1f), "退出游戏"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Application.Quit();
}
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.7f, Screen.width * 0.2f, Screen.height * 0.1f), "返回主菜单"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Time.timeScale = 1;
Application.LoadLevel("first");
}
}
void Update()
{
}
}
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
quanju.LunTotal = PlayerPrefs.GetInt("LunTai");
重点这两句话，实现了对这个轮胎个数数据的读取，然后再存储
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.6f, Screen.width * 0.2f, Screen.height * 0.1f), "再试一次"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Time.timeScale = 1;
Application.LoadLevel("choose");
}
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.8f, Screen.width * 0.2f, Screen.height * 0.1f), "退出游戏"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Application.Quit();
}
if (GUI.Button(new Rect(Screen.width * 0.45f, Screen.height * 0.7f, Screen.width * 0.2f, Screen.height * 0.1f), "返回主菜单"))
{
quanju.LunTotal += quanju.lun;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
Time.timeScale = 1;
Application.LoadLevel("first");
}
就是点击了按钮才会存储呢，
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
quanju.LunTotal = PlayerPrefs.GetInt("LunTai");这是unity自带的数据库功能，真的好方便，
这样这个轮胎的个数就能很好的记录下来了，就算是重新启动游戏数据也不会丢失的，所以我们就可以有了新游戏模式跟游戏回顾模式，是不是很高大上呢，至于怎么实现，我想大家都很清楚，新游戏模式就是点击后清除所有数据，然后进入游戏场景，
if (GUI.Button(new Rect(playButton), "新游戏"))
{
audio.PlayOneShot(beep);
//menuPage = "main";
PlayerPrefs.DeleteAll();
Application.LoadLevel("choose");
}
PlayerPrefs.DeleteAll();这一句就是unity自带的数据库的清除数据的语句，当然也很方便啦；
游戏回顾模式就是直接进入游戏场景就好啦；
说了半天还没到游戏商店呢，先上个图吧；
这个就是商店啦，不过是用了点GUI的输入输出罢了，我们的比例是1：500；嘿嘿，都是用了数据库，直接上大片代码，是不是很爽呢；

if (quanju.LunTotal<number)
{
}
else
{
quanju.LunTotal = quanju.LunTotal - number;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
quanju.JinTotal = quanju.JinTotal + number * 500;
PlayerPrefs.SetInt("JinBi", quanju.JinTotal);
}
}
if (GUI.Button(new Rect(Screen.width * 0.42f, Screen.height * 0.8f, Screen.width * 0.2f, Screen.height * 0.1f), "返回"))
{
Application.LoadLevel("choose");
quanju.shangdian = 0;
}
}
if(quanju.shangdian==2)
{
if (GUI.Button(new Rect(Screen.width * 0.42f, Screen.height * 0.3f, Screen.width * 0.2f, Screen.height * 0.3f), "只能通过游戏"+"\n"+"获取轮胎"))
{
}
if (GUI.Button(new Rect(Screen.width * 0.42f, Screen.height * 0.7f, Screen.width * 0.2f, Screen.height * 0.1f), "返回"))

quanju.shangdian = 0;
}
}
//GUIStyle bb1 = new GUIStyle();
//bb1.fontSize = 30;
//bb1.normal.textColor = new Color(0, 0, 0);
//quanju.LunTotal = PlayerPrefs.GetInt("LunTai");
//GUI.Label(new Rect(Screen.width * 0.5f, Screen.height * 0.5f, 0, 0), "轮胎个数" + "\n" + quanju.LunTotal.ToString() + " 个",bb1);
}
}
FromText = GUI.TextField(new Rect(Screen.width * 0.31f, Screen.height * 0.44f, Screen.width * 0.1f, Screen.height * 0.08f), FromText,bb1);
在这之前呢，我们public了一个FormText，不是我不想直接定义整型，是GUI的输入估计只能是字符等，这样呢，只能是String了，这样呢，我就需要字符转整型了，
int.TryParse(FromText, out number);
unity中的字符转整型是这样用的，估计是其中一种用法，应该还用很多种方法，然而整型转字符型却很简单，直接是整型.ToString();是不是很爽，这样呢，我们就可以直接用number了，
quanju.LunTotal = quanju.LunTotal - number;
PlayerPrefs.SetInt("LunTai", quanju.LunTotal);
quanju.JinTotal = quanju.JinTotal + number * 500;
PlayerPrefs.SetInt("JinBi", quanju.JinTotal);
点下兑换按钮，我们要相应的做出显示的变化以及存储数据，这样就好了，帅吧；，今天就这样了，
