你能帮我解决 Unity3d 项目中数组或枚举中的错误吗？

Question

您好，我开始在 Unity3d 中开发游戏，但我的代码或检查器中有错误。

我的错误出现在我分配 itemToEquip 两次的数组 arthursButtonsDescription 中。第一轮一切顺利 arthursButtonsDescription[0].name 是“0”，但第二轮我分配 arthursButtonsDescription[4].name=4 和 arthursButtonsDescription[0].name 也是 4，这是我的错误。

我录制了有关此错误的视频：https://youtu.be/wZuFo5uhL5o

我将我的错误项目上传到：https://uloz.to/file/zfyxYuOiHTa4/dandd-zip#!ZGp4LmR2AzV0MTSvMGxkMwOvZwEuBGEuIRuhIyM6MJAgFGIuAj==/dandd-zip

您的问题似乎出在 SaveLoadStarter 中。

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

public class SaveLoadStarter : MonoBehaviour
{
    public void LoadClick()
    {
        Equipment itemToEquip = gameObject.AddComponent<Equipment>();

        itemToEquip.name = "0";
        itemToEquip.equipSlot = EquipmentSlot.Head;
        Debug.Log("iTE0: " + itemToEquip.name);
        EquipmentManager.instance.Equip(itemToEquip);

        itemToEquip.name = "4";
        itemToEquip.equipSlot = EquipmentSlot.Shield;
        Debug.Log("iTE4: " + itemToEquip.name);
        EquipmentManager.instance.Equip(itemToEquip);
    }
}

您声明 itemToEquip，设置它，然后再次设置它。

您需要创建一个新的设备对象。否则，您只是在更改第一个对象中的值。

试试这样的：

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

public class SaveLoadStarter : MonoBehaviour
{
    public void LoadClick()
    {
        Equipment itemToEquip = gameObject.AddComponent<Equipment>();

        itemToEquip.name = "0";
        itemToEquip.equipSlot = EquipmentSlot.Head;
        Debug.Log("iTE0: " + itemToEquip.name);
        EquipmentManager.instance.Equip(itemToEquip);

        itemToEquip = gameObject.AddComponent<Equipment>();

        itemToEquip.name = "4";
        itemToEquip.equipSlot = EquipmentSlot.Shield;
        Debug.Log("iTE4: " + itemToEquip.name);
        EquipmentManager.instance.Equip(itemToEquip);
    }
}
