Question

我试图在关卡结束时保存得分，但是我遇到了一些错误。

这是得分脚本：

using UnityEngine;
using System.Collections;

public class ScoreManager : MonoBehaviour {
    public float score;

    private IEnumerator Wait() {
        yield return new WaitForSeconds(3);
        Application.LoadLevel(Application.loadedLevel);
    }

    void TimerOfDeath(){
        if(score <= 0){
            GameObject.Find("TooLateGUI").guiTexture.enabled = true;
            GameObject.Find("Score").guiText.enabled = false;
            StartCoroutine(Wait());


        }
    }

    void Update () {
            {
            score -= 60 * Time.deltaTime;
            guiText.text = "Score: " + (int) score;
            TimerOfDeath ();
        }
    }
}

以及级别末尾的保存脚本：

 using UnityEngine;
    using System.Collections;
    using System;
    using System.Runtime.Serialization.Formatters.Binary;
    using System.IO;

    public class Saving : MonoBehaviour
    {
        GameObject Score;
        void Start(){
             Score = GameObject.Find("Score").GetComponent<ScoreManager>();
        }

        void OnTriggerEnter( Collider other)
        {
            if(other.gameObject.tag == "Player")
            {
                GameObject[] NoOrbs;
                NoOrbs = GameObject.FindGameObjectsWithTag("Pickup");
                int count = NoOrbs.Length;
                if(count == 0){
                GameControl.control.levelcount += 1; //add +1 to levelcount


                    int newScore = (int)ScoreManager.score; //get score and put in newScore as int

                GameControl.control.score = newScore; //score from GameControl = this new score
                GameControl.control.Save();
                }
            }
        }
    }

2个错误：第11行：无法将ScoreManager隐式转换为UnityEngine.Gameobject，第25行：非静态字段，方法或属性需要对象引用。

我也添加了保存/加载脚本，只是有人需要信息或者可以使用脚本：

using UnityEngine;
using System.Collections;
using System;
using System.Runtime.Serialization.Formatters.Binary;
using System.IO;

public class GameControl : MonoBehaviour {
    public static GameControl control;

    public float score;
    public int levelcount;

    void Awake () {
        if(control == null)
        {
            DontDestroyOnLoad(gameObject);
            control = this;
        }
        else if(control != this)
        {
            Destroy(gameObject);
        }
    }
    public void Save()
    {
        BinaryFormatter bf = new BinaryFormatter();
        FileStream file = File.Create(Application.persistentDataPath + "/playerInfo.dat");

        PlayerData data = new PlayerData();
        data.score = score;
        data.levelcount = levelcount;

        bf.Serialize(file, data);
        file.Close();
    }
    public void Load()
    {
        if(File.Exists(Application.persistentDataPath + "/playerInfo.dat"))
        {
            BinaryFormatter bf = new BinaryFormatter();
            FileStream file = File.Open(Application.persistentDataPath + "/playerInfo.dat", FileMode.Open);
            PlayerData data = (PlayerData)bf.Deserialize(file);
            file.Close();

            score = data.score;
            levelcount = data.levelcount;

        }
    }
    public void overwriteSaveFile()
    {
        if(File.Exists(Application.persistentDataPath + "/playerInfo.dat"))
        {
            BinaryFormatter bf = new BinaryFormatter();
            File.Delete(Application.persistentDataPath + "/playerInfo.dat");
        }
    }
}
[Serializable]
class PlayerData
{
    public float score;
    public int levelcount;
}

Answer 1

第一个很简单，你在这一行中将你的变量声明为GameObject：

GameObject Score;

当你真的想要存储ScoreManager时。您需要将其更改为：

ScoreManager Score;

第二个是通过改变

来解决的

int newScore = (int)ScoreManager.score; //get score and put in newScore as int

到

int newScore = (int)Score.score; //get score and put in newScore as int

因为“ScoreManager”是类的名称，而您使用的实例名为“Score”。也许看一下静态函数是什么;）我还建议你将Score变量重命名为明确表示它实际上是ScoreManager的东西。我通常只使用

ScoreManager scoreManager;

或

ScoreManager myScoreManager;

请注意实例名称通常以小写字符开头，以及具有大写字符的类。这就是为什么在代码“Score”中突出显示，stackoverflow认为它是一个类，当它实际上是一个实例名称

将得分从其他脚本保存到savecript
