C# 我怎样才能让钱涨起来而不是重复？

所以我用c#在unity中创建了一个2D游戏。现在，当我玩游戏，我捡起一块宝石，钱从0到1，如果我捡起另一块宝石，它又从0到1，我不知道为什么它一直回到0。我应该做些什么改变，这样当我捡起宝石时，钱确实会增加，并确保它与储蓄系统一起工作。我有4个脚本：GemPick、Player、Playerdata和SaveSystem

请帮助我，因为我需要尽快解决这个问题，因为我必须在11月底之前完成比赛

选择脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Gempickup : Player
{
    public void OnTriggerEnter2D(Collider2D Collision)
    {
        if (Collision.gameObject.tag.Equals("Player"))
        {            
            Destroy(gameObject);
            money = money + 1;
        }        
    }
}

玩家脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{
    public int level;
    public int health;
    public int money;

    public void Update()
    {
        if (Input.GetKeyDown("k"))
        {
            SaveSystem.SavePlayer(this);
        }

        if (Input.GetKeyDown("l"))
        {
            PlayerData data = SaveSystem.Loadplayer();

            level = data.level;
            health = data.health;
            money = data.money;

            Vector3 position;
            position.x = data.position[0];
            position.y = data.position[1];
            position.z = data.position[2];
            transform.position = position;
        }
    }
}

PlayerData脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
public class PlayerData
{
    public int level;
    public int health;
    public int money;
    public float[] position;

    public PlayerData(Player player)
    {
        level = player.level;
        health = player.health;
        money = player.money;

        position = new float[3];
        position[0] = player.transform.position.x;
        position[1] = player.transform.position.y;
        position[2] = player.transform.position.z;
    }
}

存储系统脚本：

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

public static class SaveSystem
{
    public static void SavePlayer (Player player)
    {
        BinaryFormatter formatter = new BinaryFormatter();
        string path = Application.persistentDataPath + "/player.fun";
        FileStream stream = new FileStream(path, FileMode.Create);

        PlayerData data = new PlayerData(player);

        formatter.Serialize(stream, data);
        stream.Close();
    }

    public static PlayerData Loadplayer()
    {
        string path = Application.persistentDataPath + "/player.fun";
        if (File.Exists(path))
        {
            BinaryFormatter formatter = new BinaryFormatter();
            FileStream stream = new FileStream(path, FileMode.Open);

            PlayerData data = formatter.Deserialize(stream) as PlayerData;
            stream.Close();

            return data;            
        }
        else
        {
            Debug.LogError("Save file not found in" + path);
            return null;
        }
    }
}

我不想让您挂起电话，也不是说我不使用Unity，我不想向您展示以下代码。如果没有统一，我会这样设计它

public class Game
{

    public class GameObject
    {
        internal float[] position;

    }

    static public void Destroy(GameObject go)
    {
        // some object destruction
    }

    public class Gem : GameObject
    {
        // inherits position
    }

    public class Character : GameObject
    {
        // inherits position
        internal int health;
    }

    public class Enemy : Character
    {
        // inherits position and health
        public void OnCollision(GameObject other)
        {
            if (other is Player)
            {
                health--;
                if (health==0)
                {
                    Destroy(this);
                }
            }
        }
    }

    [System.Serializable]
    public class Player : Character
    {
        // inherits position and health
        // don't expose your internals
        // and probably should be properties.. but I don't know if they work with the serializer
        internal int level;
        internal int money;

        public void OnCollision(GameObject other)
        {
            if (other is Gem)
            {
                Destroy(other);
                money++;
            }
            else if (other is Enemy)
            {
                health--;
                if (health == 0)
                {
                    //game over;
                }
            }
        }
    }
}

在玩家脚本中尝试此操作，而不是将脚本附加到gem游戏对象。只需将Gem标签添加到Gem

public void OnTriggerEnter2D(Collider2D Collision)
{
    if (Collision.gameObject.tag.Equals("Gem"))
    {

        Destroy(Collision.gameObject);
        money = money + 1;



    }

}

为什么

player

不属于

player

类？如果您从

player

派生

gemcopper

并创建

gemcopper

对象，则

gemcopper

对象中的

money

对象不会链接到

player

对象。。在

player

和

playerdata

中都有一个

money

对象？！你应该重新思考你的设计，思考每个对象和功能应该在哪里。但我担心你缺少C#如何工作的基本要素。。。你应该开始一个简单的教程。。。不是从统一开始你是在增加被摧毁物体的钱，你应该增加玩家的金钱…同意@JHBonarius的设计…如果你在每个gem上创建一个GemPick实例，每个gem都有自己的金钱变量，默认情况下都从0开始…谢谢你，我删除了GemPick脚本并将其放在玩家中。像这样的嵌套类无论是否统一，都不是一个好模式。这并不是说它本质上是坏的，而是说它应该只有在有充分理由的情况下才能做到。当你意识到你没有使用Unity时，你没有检查Unity提供了什么对象（比如GameObject），所以你不必再次指定它们

GameObject

也是

final

；Unity开发者不应该（或不允许）从它扩展。是的，这是一个设置。有一些想法给了继承的理由，但它们并没有给这个答案增加更多的价值。团结是不同的，但我不会那样做
