unity-game-engine - String.Format 显示 SerializeField 数据中的旧实例数据 - 如何修复？

Question

我试图在运行时在 Unity 中显示一个工具提示，其中包含以下信息:

Spell Name (string)
Cast Time (float)
Damage (int)
Description (string)

我在脚本中正确设置了所有内容，并且工具提示 GetDescription() 函数正确地从包含所需信息的序列化字段中提取了法术名称、施法时间和伤害所需的信息。但是，“描述序列化”字段尽管已填充，但并未显示在工具提示中。

当我将 Debug.Log(description) 行放入函数中时，控制台显示描述的内容为空。我将描述存储在名为“description”的字符串中，它是一个 [SerializeField]，以便可以在 Unity Inspector 中设置描述。这与我存储其他法术信息(法术名称、施法时间和伤害)的方法相同。

当我运行游戏构建并转到工具提示文本字段所在的层次结构时，我可以直观地确认“描述”字符串的内容没有附加到文本字段(我正在使用启用了富文本的字段)。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using UnityEngine;

[Serializable]
public class Spell : IUseable, IMoveable, IDescribable
{
    [SerializeField]
    private string name;

    [SerializeField]
    private int damage;

    [SerializeField]
    private float castTime;

    [SerializeField]
    private string description;

    public string GetDescription()
    {
        return string.Format("{0}\n Cast time: {1} second(s) 
            \n Damage:{2} \n {3}", name, castTime, damage, description);
    }
}

当我运行构建并尝试工具提示时，我得到如下内容:

Explosion
Cast Time: 2.5 second(s)
Damage: 5

不过，它应该显示类似这样的内容:

Explosion
Cast Time: 2.5 second(s)
Damage: 5
Creates a powerful explosion, injuring those caught in its blast.

更新:

private void Awake()
{
    toolTipTitle = toolTip.GetComponentInChildren<Text>();
}

public void ShowTooltip(Vector3 position, IDescribable description)
{
    toolTip.SetActive(true);
    toolTip.transform.position = position;
    toolTipTitle.text = description.GetDescription();
}

更新:

我将 Debug.Log 附加到 ShowTooltip() 函数以查看 description.GetDescription() 的内容，它确实引用了序列化字段中数据的旧实例(我将其更改为 FireTest，并使用 10第二次施法时间)。

Explosion
Cast time: 2.5 second(s)
Damage:5

UnityEngine.Debug:Log(Object)
UIManager:ShowTooltip(Vector3, IDescribable) (at Assets/Scripts/Managers/UIManager.cs:179)
ActionButton:OnPointerEnter(PointerEventData) (at Assets/Scripts/Buttons/ActionButton.cs:151)
UnityEngine.EventSystems.EventSystem:Update()

更新:

附加一些 Debug.Log 命令后，看起来代码正在引用 SerializeFields 中包含的旧数据实例的名称、castTime 和损坏情况。这个旧实例没有描述字段，这解释了为什么它没有被添加到工具提示中。寻找有关如何强制代码从 SerializeFields 重新获取所需数据的建议，而不是依赖于似乎是缓存的数据值(老实说，不确定这如何可能......但这个缓存的数据也是出现在应该从这些字段中提取数据的其他地方，例如显示法术名称并倒计时施法时间的施法栏，测试显示施法栏使用旧实例数据而不是法术书中的数据。法术书以及下面的操作按钮供引用:

弄清楚了 - 我不小心在另一个游戏对象中创建了脚本字段数据的克隆，而游戏正在使用它。按照回答结束此问题 - 非常感谢您的帮助! =)
