StackOverflowException：请求的操作导致堆栈溢出

Question

我用 C# 和界面在 Unity2d 中编写了一些代码。 LevelingSystem.cs 被放入空的游戏对象中。

我收到错误：

WhosebugException: The requested operation caused a stack overflow.
PlayerCap.get_actExp () (at Assets/Scripts/player/PlayerCap.cs:17)
PlayerCap.get<message truncated>

CapLevel.cs

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


interface ICapLevel
{

    float multiplierA { get; set; }
    float multiplierB { get; set; }
    float multiplierC { get; set; }
    float multiplierD { get; set; }

    int lvlCap { get; set; }
    List<double> expCap { get; set; }
    float actExp { get; set; }

    void GenerateExpPerLvl();
    float RequiredExp(int level);
}

PlayerCap.cs

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

public class PlayerCap : ICapLevel
{

    public float multiplierA { get { return multiplierA; } set { multiplierA = 280f; } }
    public float multiplierB { get { return multiplierB; } set { multiplierB = 100f; } }
    public float multiplierC { get { return multiplierC; } set { multiplierA = 1.15f; } }
    public float multiplierD { get { return multiplierD; } set { multiplierD = 2.3f; } }

    public int lvlCap { get { return lvlCap; } set { lvlCap = 210; } }

    public List<double> expCap { get { return expCap; } set { expCap = new List<double>(); } }
    public float actExp { get { return actExp; } set { actExp = 0f; } }

    public void GenerateExpPerLvl()
    {
        Debug.Log("implementation successful");

        for (int expLevel = 1; expLevel <= lvlCap; expLevel++)
        {
            expCap.Add(RequiredExp(expLevel - 1));
        }

    }

    public float RequiredExp(int level)
    {
        double formulaRounded;
        var formula = multiplierB * (Mathf.Pow(multiplierC, level - 1)) + multiplierA * (Mathf.Pow(level, multiplierD));
        if (formula < 1000)
        {
            if ((formula % 10) == 0)
            {
                formulaRounded = formula;
                return (float)formulaRounded;
            }
            else
            {
                formulaRounded = Math.Round((formula / 1000), 1, MidpointRounding.AwayFromZero);
            }
        }
        else
        {
            formulaRounded = Math.Round((formula / 1000), 0, MidpointRounding.AwayFromZero);
        }
        return (float)formulaRounded * 1000;

    }
}

LevelingSystem.cs

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

public class LevelingSystem : MonoBehaviour
{
    //interface implementation
    private PlayerCap _pCap;
    private ICapLevel _ICap;

    private List<double> _pExpCap;

    private int pLvl;
    private float _pActExp;

    public void Awake()
    {
        _pCap = new PlayerCap();
        _ICap = _pCap;


    }

    private void Start()
    {
        _pActExp = _ICap.actExp;
        _ICap.GenerateExpPerLvl();
        _pExpCap = _ICap.expCap;
    }



    public void AddExp(float amount)
    {
        _pActExp += amount;
        StartCoroutine(CapLevelCheck(amount));
    }

    private IEnumerator CapLevelCheck(float amount)
    {
        while (true)
        {
            if (_pActExp >= _pExpCap[pLvl])
            {
                _pActExp -= (float)_pExpCap[pLvl];
                AddLevel(1);
            } else
            {
                Debug.Log("You Get " + amount + " Experience and you have " + pLvl + " Lvl. *Click noice!");
                break; //otherwise loop will do in infinite
            }
            yield return 0;
        }
    }

    public void AddLevel(int amount)
    {
        pLvl += amount;
    }
    public int GetActualLevel()
    {
        return pLvl;
    }
}

我尝试了一些事情，比如在方法 GenerateExpPerLvl() 中摆脱掉 for，错误消失了，所以我怀疑的是列表变量，但也许我错了。

感谢您的帮助:)

问题出在这里：

public float actExp { get { return actExp; } set { actExp = 0f; } }
                                // ^ Problem here & ^ same problem here

您在自己的 getter 和 setter 中调用属性。它会创建一个无限循环...（每次调用 actExp 它都会调用自己）

相反，您应该只写（如果访问器内部没有逻辑）：

public float actExp { get; set; }
