统一编号向导后退按钮

Question

我刚刚创建了一个数字游戏女巫猜测你在想什么数字，并将其作为TextMeshProUGUI元素显示在屏幕上。我想添加一个后退按钮，以便当您按下不正确的按钮时，TextMeshProUGUI 元素会显示在用户按下不正确按钮之前显示的值。

脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using UnityEngine.UI;
public class NumberWizard : MonoBehaviour {
[SerializeField] SceneLoader sceneLoader;
[SerializeField] int max;
[SerializeField] int min;
[SerializeField] TextMeshProUGUI guessText;
int guess;
// Use this for initialization
void Start ()
{
StartGame();
}
void StartGame()
{
NextGuess();
}
public void OnPressHigher()
{
min = guess + 1;
NextGuess();
}
public void OnPressLower()
{
max = guess - 1;
NextGuess();
}
void NextGuess()
{
guess = Random.Range(min, max+1);
guessText.text = guess.ToString();
}
public void Back()
{
//Back code should go here
}
}

你只需要记住最后的猜测：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using TMPro;
using UnityEngine.UI;
public class NumberWizard : MonoBehaviour {
[SerializeField] SceneLoader sceneLoader;
[SerializeField] int max;
[SerializeField] int min;
[SerializeField] TextMeshProUGUI guessText;
int guess;
int lastGuess;
int lastMin;
int lastMax;
// Use this for initialization
void Start ()
{
StartGame();
}
void StartGame()
{
NextGuess();
}
public void OnPressHigher()
{
lastMin = min;
min = guess + 1;
NextGuess();
}
public void OnPressLower()
{
lastMax = max;
max = guess - 1;
NextGuess();
}
void NextGuess()
{
lastGuess = guess;
guess = Random.Range(min, max+1);
guessText.text = guess.ToString();
}
public void Back()
{
guess = lastGuess;
min = lastMin;
max = lastMax;
guessText.text = guess.ToString();
}
}
