逐步讲解用C#实现俄罗斯方块之核心代码[完结篇]

 下面我们来在c#中使用这个类,在原理的新建的窗口中拖放一个Timer来控制方块移动窗口类的代码-

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace Fang
...{
    public partial class Form1 : Form
    ...{
        private sharp obj;
        public Form1()
        ...{
            InitializeComponent();
        }
        private void Form1_Load(object sender, EventArgs e)
        ...{
            obj =new sharp(this);
            obj.makeNew();
            //obj.sharp_show(this);
        }

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        ...{
            switch (Convert.ToInt32(e.KeyValue))
            ...{
                case 38://上-旋转
                    obj.Roll();
                    break;
                case 39://向右
                    obj.movRigth();
                    break;
                case 37://向左
                    obj.movLeft();
                    break;
                case 40://下-加速
                    obj.moveDown(this);
                    break;
            }
        }

        private void timMove_Tick(object sender, EventArgs e)
        ...{
            obj.moveDown(this);
        }
    }
}

对的你没有看错就是这么少,一共三个方法,一共是form_load()在加载窗口时实例化shape类 key_down()响键盘事件timMove_Tick是控件Timer[timMove]的事件触发事件
至此程序全部完成 ...如果要索要项目完全文件联系[e-mail]
