如何在控制台中显示变量

本文关键字：显示 变量 控制台 | 更新日期: 2023-09-27 18:07:20

我正在尝试创造一款简单的主机游戏，你可以通过喂养自己来照顾自己。

using System;
namespace Project1
{
static class Program
{
    static void Main(string[] args)
    {
        int hunger = 100;
        Console.WriteLine("Enter your name: ");
        string name = Console.ReadLine();
        Console.WriteLine("Good choice, " + name);
        Console.WriteLine("Press SPACE to continue");
        while (!(Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.Spacebar))
        {
            // do something
            int h = hunger - 2;
        }
        Console.WriteLine("You are hungry," + name);
        Console.WriteLine("Press F to feed");
        while (!(Console.KeyAvailable && Console.ReadKey(true).Key == ConsoleKey.F))
        {
            // do something
            int food = hunger;
        }
    }
}
}

如何在更改后显示当前饥饿?我想显示食物等级，这样玩家就知道该喂饱它，而不会意外地喂饱它。有没有可能有办法回到之前的那行这样我就不用一直复制粘贴了?谢谢。

如何在控制台中显示变量

看起来这个问题要回答得很宽泛，所以我将把它保留得很抽象。您需要在方法中放入可重用的逻辑。你需要一个"游戏循环"或"输入循环"。你需要了解变量并将它们传递给方法。

您还可能希望引入Player类，而不是各种变量来保存单独的值。

你的游戏循环可能是这样的:

ConsoleKey input = null;
do
{
    var player = DoGameLogic(input, player);
    PrintGameInfo(player);
    input = ReadInput(player);
}
while (input != ConsoleKey.Q)

当你把所有这些都整理好，并且你想让输出看起来不错时，看看使用Console在同一位置写字符串。用c# 2.0编写，. net中的高级控制台IO

您可以使用Console.CursorLeft和Console.CursorTop来修改光标的位置，并覆盖之前的值。

Cursor.Left = 0;
Console.Write("Hunger: {0:0.00}", hunger);

编辑:正如"CodeMaster"提到的，你可以这样做:

Console.Write("Test {0:0.0}".PadRight(20), hunger);

这是你想要实现的吗? -

static void Main(string[] args)
    {
        const int MAX_FEED_LEVEL = 3; //configure it as per your need
        const int HIGHEST_HUNGER_LEVEL = 0; //0 indicates the Extreme hunger
        int hunger = MAX_FEED_LEVEL, foodLevel = HIGHEST_HUNGER_LEVEL;
        string name = string.Empty;
        char finalChoice = 'N', feedChoice = 'N';
        Console.Write("Enter your name: ");
        name = Console.ReadLine();
        Console.Write("Good choice, {0}!", name);
        Console.WriteLine();
        do
        {
            Console.WriteLine();
            Console.WriteLine("current hunger level : {0}", hunger);
            if (hunger > 0)
                Console.WriteLine("You are hungry, {0}", name);
            Console.Write("Press F to feed : ");
            feedChoice = (char)Console.ReadKey(true).Key;
            if (feedChoice == 'F' || feedChoice == 'f')
            {
                if (foodLevel <= MAX_FEED_LEVEL && hunger > HIGHEST_HUNGER_LEVEL)
                {
                    hunger = hunger - 1; //decrementing hunger by 1 units
                    foodLevel += 1; //incrementing food level
                    Console.WriteLine();
                    Console.WriteLine("Feeded!");
                    Console.WriteLine("Current Food Level : {0}", foodLevel);
                }
                else
                {
                    Console.WriteLine();
                    Console.WriteLine("Well Done! {0} you're no more hungry!", name);
                    goto END_OF_PLAY;
                }
            }
            else
            {
                Console.Clear();
                Console.WriteLine();
                Console.Write("You chose not to feed !");
            }
            Console.WriteLine();
            Console.Write("want to continue the game ? (Y(YES) N(NO))");
            finalChoice = (char)Console.ReadKey(true).Key;
        } while (finalChoice == 'Y' || finalChoice == 'y');
    END_OF_PLAY:
        Console.WriteLine();
        Console.Write("===GAME OVER===");
        Console.ReadKey();
    }
