你好我是GameDevelopment的新手，我正在开发一款2D平台游戏，游戏运行完美，甚至数据脚本正在开展工作，但我实际面临的问题是如果我在与敌人发生碰撞时继续死亡。例如：如果我在一分钟内死了10次（我只能死3次并弹出游戏菜单，我只需使用重启级别再次启动级别）。数据库重置其健康值，manavalue回到0.我希望法术力值和健康值保留在数据库中，以便玩家可以升级生命值和法力值。
有没有办法解决它，所以即使我在10分钟内死了100次数据库也不会崩溃？[请忽略我为他自己的理解写下的所有评论]

using System.Collections.Generic;

这是我保存数据的脚本。我正在使用BinaryFormatters（）：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
public class DataController : MonoBehaviour {
public static DataController instance = null;
public GameData data;
public bool devMode; //to help "sync" data between editor and mobile
string dataFilePath; //path where file is stored
BinaryFormatter bf; //helps save/load data in binary files
void Awake () {
//code to make a singleton
if (instance == null){
instance = this;
DontDestroyOnLoad(gameObject);
}
else{
Destroy(gameObject);
}
bf = new BinaryFormatter();
dataFilePath = Application.persistentDataPath + "/game.dat";
//Debug.Log(dataFilePath);
}
public void RefreshData(){
if (File.Exists(dataFilePath)){
FileStream fs = new FileStream(dataFilePath, FileMode.Open);//preparing the game.dat file to edit
data = (GameData)bf.Deserialize(fs); //bringing the contents from the database file in object format
fs.Close();
}
}
public void SaveData(){
FileStream fs = new FileStream(dataFilePath, FileMode.Create);
bf.Serialize(fs, data);
fs.Close();
}
public void SaveData(GameData data)
{
FileStream fs = new FileStream(dataFilePath, FileMode.Create);
bf.Serialize(fs, data);
fs.Close();
}
public bool IsUnlocked(int levelNumber){
return data.leveldata[levelNumber].isUnlocked;
}
public int GetStars(int levelNumber){
return data.leveldata[levelNumber].starsAwarded;
}
void OnEnable(){
CheckDB();
}
void CheckDB(){
if (!File.Exists(dataFilePath))
{
//platform depended compilation
#if UNITY_ANDROID
CopyDB();
#endif
}
else{
if (SystemInfo.deviceType == DeviceType.Desktop)
{
string destFile = System.IO.Path.Combine(Application.streamingAssetsPath, "game.dat");
File.Delete(destFile);
File.Copy(dataFilePath, destFile);
}
if (devMode){
if (SystemInfo.deviceType == DeviceType.Handheld){
File.Delete(dataFilePath);
CopyDB();
}
}
RefreshData();
}
}
void CopyDB(){
string srcFile = System.IO.Path.Combine(Application.streamingAssetsPath, "game.dat");
//retrieve db file from apk
WWW downloader = new WWW(srcFile);
while (!downloader.isDone)
{
//nothing to be done while our db gets our db file
}
//then save file to Apllication.persistentdataPath
File.WriteAllBytes(dataFilePath, downloader.bytes);
RefreshData();
}
}
这是健康栏滑块和法术力栏滑块的脚本：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class HealthAndManaBar : MonoBehaviour
{
public Image HealthBar;
public Image ManaBar;
public RectTransform manabutton;
public RectTransform healthbutton;
// Use this for initialization
public float healthValue;
public float manaValue;
void Start()
{
healthValue = GameController.instance.data.playerHealth;
manaValue = GameController.instance.data.playerMana;
HealthChange(healthValue);
ManaChange(manaValue);
}
// Update is called once per frame
void Update()
{
if (manaValue < GameController.instance.data.playerMana)
{
manaValue += Time.deltaTime * 20;
ManaChange(manaValue);
}
if (healthValue < 0)
{
healthValue = 0;
HealthChange(healthValue);
}
}
public void HealthChange(float healthValue)
{
float amount = (healthValue / GameController.instance.data.playerHealth) * 180.0f / 360;
HealthBar.fillAmount = amount;
float buttonAngle = amount * 360;
healthbutton.localEulerAngles = new Vector3(0, 0, -buttonAngle);
}
public void ManaChange(float manaValue)
{
float amount = (manaValue / GameController.instance.data.playerMana) * 180.0f / 360;
ManaBar.fillAmount = amount;
float buttonAngle = amount * 360;
manabutton.localEulerAngles = new Vector3(0, 0, -buttonAngle);
}
}
