控制臺(tái)調(diào)用
framework里帶的Point類坐標(biāo)為double型舀透，用不到，所以封裝了個(gè)簡(jiǎn)單的决左，夠用就行
public class Point
{
public int X { get; set; }
public int Y { get; set; }
public Point(int x, int y)
{
X = x;
Y = y;
}
public override string ToString()
{
return "(" + X + "," + Y + ")";
}
}
之后會(huì)實(shí)現(xiàn)WPF版本愕够，所以UI實(shí)現(xiàn)和邏輯還是分開(kāi)比較好
將G2048類和Point類放一起生成動(dòng)態(tài)庫(kù)BizLogic.dll
新建控制臺(tái)程序添加引用，調(diào)用即可
using BizLogic;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApp
{
class Program
{
static void Main(string[] args)
{
G2048 g = new G2048();
g.GameOvered += GGWP;
Console.WriteLine(g.ToString());
while (true)
{
int i = 0;
try
{
i = Convert.ToInt16(Console.ReadLine());
g.Operate((G2048.Direction)i);
Console.WriteLine(g.ToString());
}
catch { }
}
}
//游戲結(jié)束的實(shí)現(xiàn)
static void GGWP()
{
Console.WriteLine("GGWP");
}
