简单小游戏制作

控制台基础设置

//隐藏光标
Console.CursorVisible = false;
//通过两个变量来存储舞台的大小
int w = 50;
int h = 30;
//设置舞台（控制台）的大小
Console.SetWindowSize(w, h);
Console.SetBufferSize(w, h);

多个场景

int nowSceneID = 1;
while (true)
{
	//不同的场景ID，进行不同的逻辑处理
	switch (nowSceneID)
	{
		//开始场景
		case 1:
			Console.Clear();
			Console.WriteLine("开始场景");
			break;
		//游戏场景
		case 2:
            Console.Clear();
            Console.WriteLine("游戏场景");
            break;
		//结束场景
		case 3:
            Console.Clear();
            Console.WriteLine("结束场景");
            break;
	}
}

开始场景逻辑实现

Console.SetCursorPosition(w / 2 - 7, 4);
Console.Write("勇者斗恶龙");

//当前选项的编号
int nowSelIndex = 0;
//因为要输入，完没可以构造一个开始界面自己的死循环
//专门用来处理开始场景相关逻辑
while (true)
{
	//用一个标识来处理想要在while循环内部的switch逻辑执行时希望退出外层循环时改变标识即可。
	bool isQuitWhite = false;
	//显示内容
	//先设置光标位置，再显示内容
	//根据当前选择的编号来决定是否变色。
	Console.SetCursorPosition(w / 2 - 6, 7);
	Console.ForegroundColor = nowSelIndex == 0 ? ConsoleColor.Red : ConsoleColor.White;
	Console.Write("开始游戏");
    Console.SetCursorPosition(w / 2 - 6, 9);
    Console.ForegroundColor = nowSelIndex == 1 ? ConsoleColor.Red : ConsoleColor.White;
    Console.Write("退出游戏");
    //检测输入
    //检测玩家输入的一个键内容，并且不会在控制台上显示输入的内容
    char input=Console.ReadKey(true).KeyChar;

	switch (input)
	{
		case 'w':
		case 'W':
			--nowSelIndex;
			if (nowSelIndex < 0)
				nowSelIndex = 0;
			break;
		case 's':
		case 'S':
			++nowSelIndex;
			if (nowSelIndex > 1)
				nowSelIndex = 1;
			break;
		case 'j':
		case 'J':
			if (nowSelIndex == 0)
			{
				//1.改变当前选择的场景ID
				nowSceneID = 2;
				//2.退出内层while循环
				isQuitWhite = true;
			}
			else
			{
				//关闭控制台
				Environment.Exit(0);
			}
			break;
	}
	if (isQuitWhite)
	{
		break;
	}
}

游戏场景
