c# - Unity Inspector 在运行时清除变量

Question

所以我已经有了一个非常基本的战斗脚本，它将玩家和脚本所附加的任何敌人纳入检查器中。但是，当我点击“播放”来测试游戏时，我添加到检查器中的玩家变量的值消失了，就好像我从未添加任何内容一样。当我停止时它再次出现。

我的 super 简单的战斗脚本

using UnityEngine;
using System.Collections;
using UnityEditor;
using UnityEngine.UI;

public class BasicCombat : MonoBehaviour

{

public KennedyClass playerK;
public pawnClass pawn;
public archerClass archer;



// Use this for initialization
void Start()
{

    playerK = GetComponent<KennedyClass>();
    pawn = GetComponent<pawnClass>();
    archer = GetComponent<archerClass>();
    playerK.charHP = playerK.maxHP;

}

// Update is called once per frame
void Update()
{

}

public void Attack()
{

    if (gameObject.CompareTag("Pawn")) 
    {
        while (playerK.charHP != 0 & pawn.pawnHP !=0)
        {               
                playerK.charHP -= pawn.pawnDamage;
                playerK.HPCount();
                Debug.Log("Player - " + playerK.charHP);
                var option = EditorUtility.DisplayDialogComplex(
                     "Attack",
                     "Do you want to attack?",
                     "Yes",
                     "No",
                     "Exit");

                switch (option)
                {
                    case 0:
                        pawn.pawnHP -= playerK.atkP;
                        Debug.Log("Pawn - " + pawn.pawnHP);
                        break;                          
                    case 1:
                        //Exit loop (for now)
                        break;
                    case 2:
                        //Exit loop (for now)
                        break;
                }                
        }          
    }
    else if (gameObject.CompareTag("Archer"))
    {
        while (playerK.HP != 0 & pawn.pawnHP != 0)
        {
            playerK.HP -= archer.archerDamage;
            Debug.Log("Player - " + playerK.HP);
            var option = EditorUtility.DisplayDialogComplex(
                 "Attack",
                 "Do you want to attack?",
                 "Yes",
                 "No",
                 "Exit");

            switch (option)
            {
                case 0:
                    archer.archerHP -= playerK.atkP;
                    Debug.Log("Archer - " + archer.archerHP);
                    break;
                case 1:
                    //Exit loop (for now)
                    break;
                case 2:
                    //Exit loop (for now)
                    break;
            }
        }
    }


    if (playerK.charHP == 0)
    {
        Debug.Log("Player death");
        Application.LoadLevel(0);
    }


    if (pawn.pawnHP == 0)
    {
        Debug.Log("Enemy death");
        pawn.GetComponent<Renderer>().enabled = false;
    }
    if (archer.archerHP == 0)
    {
        Debug.Log("Enemy death");
        archer.GetComponent<Renderer>().enabled = false;
    }
  }
}

Answer 1

您正在更改 Start 中的变量功能。删除该行

playerK = GetComponent<KennedyClass>();

来自您的Start函数将变量保留在检查器中设置的状态。

为了解释一下发生了什么，当您在检查器中分配玩家变量时，您将给它一个对 GameObject 的引用。与 KenedyClass附有脚本。这是我假设您想要的引用。

但是，当您调用playerK = GetComponent<KennedyClass>();时然后你会说'忘记我在检查器中设置的内容，寻找 KennedyClass 这个脚本附加到的游戏对象上的组件并设置 playerK等于它'。如果没有KennedyClass脚本附加到这个游戏对象，我假设没有，那么它将返回 null并删除检查器中的设置。
