[英]Unity - Save Progress In Game?
Hi I am creating a small game with Unity3d. 嗨,我正在用Unity3d创建一个小游戏。 But now I have trouble saving some variables.
但是现在我很难保存一些变量。 Now I am using the following code
现在我正在使用以下代码
void Awake(){
proiettili = PlayerPrefs.GetFloat ("PallottoleOgniSecondo");
}
void OnApplicationQuit(){
PlayerPrefs.SetFloat ("PallottoleOgniSecondo", proiettili);
PlayerPrefs.Save();
}
This way I can save the variable, but only when I try on unity, if I try does not work on Android. 这样,我可以保存变量,但是仅当我尝试统一时(如果我尝试在Android上不起作用),即可保存该变量。 you know how I can fix?
你知道我该怎么解决吗?
This is how you do it for an example class called MyClass 这是为名为MyClass的示例类执行的操作
using UnityEngine;
using System.Collections;
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;
[Serializable]
public class MyClass {
public int myInt;
public void Save(){
BinaryFormatter bf = new BinaryFormatter();
FileStream file = File.Create (FilePath());
bf.Serialize(file, this);
file.Close();
}
public void Load(){
if(File.Exists(FilePath())){
BinaryFormatter bf = new BinaryFormatter();
FileStream file = File.Open(FilePath(), FileMode.Open);
MyClass loaded = bf.Deserialize(file) as Brochure;
myInt = loaded.myInt;
}
}
static string FilePath()
{
return Application.persistentDataPath + "/myClass.dat";
}
}
You should try it like this 你应该这样尝试
PlayerPrefs.SetInt("score",ScoreManager.score);
PlayerPrefs.Save();
score=PlayerPrefs.GetInt("score");
I've tried this in my project for a Web and WebGL build, if you need to know about serialization I could give you an example 我已经在我的Web和WebGL构建项目中尝试过此方法,如果您需要了解序列化的知识,我可以举个例子
如果您已添加“ android.permission.WRITE_EXTERNAL_STORAGE”,请检查您对Android项目的权限。
