兵棋系列2----兵棋游戏中地图滑动和委托消息
前几天写了一个六边形阵列的算法，今天周末比较闲，下午没事就做了做兵棋的地图操作，一点一点的做吧，总会做好，毕竟我也经常玩各种棋，对做一个这类型的小游戏非常感兴趣。
首先来解释下，下面要出现代码的操作。如上图，当鼠标指针移动到地图的四个边时，地图会自动左右上下滑动（地图比这个from要大很多，不这么做地图显示不完整了，不要跟我说用滚动条，那个给人感觉不好，这也是兵棋里不会缺少的操作吧），同时下面的消息框会记录鼠标的位置，这个消息框前期为我开发时显示一些测试信息用的，后期应该会把它改成一个功能区（部队参数、将领参数、环境参数、消息显示等等吧）
下面把源代码放出来，懂得大大们可以指点下怎么做。
C#开发中，控件和控件之间的消息传递有多种方式，我一般选择委托，毕竟灵活方便。以下是两种传递消息的模式，我选择了第一个，放弃了第二个；其实个人觉得第二个方法更优秀，它作为一个继承基类，可以很安全的把消息传递给它的上层类；第一种采用静态，优势是灵活方便，弊端是一个委托几乎只在一个功能上使用。
选择的传递消息模式
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 6 namespace UI 7 { 8 public enum MsgType 9 { 10 /// <summary> 11 /// 常规消息显示（黑色） 12 /// </summary> 13 Show, 14 /// <summary> 15 /// 提示信息（绿色） 16 /// </summary> 17 Info, 18 /// <summary> 19 /// 状态栏显示 20 /// </summary> 21 State, 22 /// <summary> 23 /// 错误消息，可识别，可控类型（蓝色） 24 /// </summary> 25 Error, 26 /// <summary> 27 /// 警告消息，程序异常，不可处理（红色） 28 /// </summary> 29 Warn, 30 /// <summary> 31 /// 他人发送消息的颜色 32 /// </summary> 33 OtherMessage, 34 /// <summary> 35 /// 本人发送消息的颜色 36 /// </summary> 37 OwnerMessage 38 } 39 40 class MsgEventArgs 41 { 42 private string _message; 43 44 public string Message 45 { 46 get { return _message; } 47 set { _message = value; } 48 } 49 50 private MsgType _type; 51 52 public MsgType Type 53 { 54 get { return _type; } 55 set { _type = value; } 56 } 57 58 public MsgEventArgs(string msg) 59 { 60 this._message = msg; 61 62 this._type = MsgType.Show; 63 } 64 public MsgEventArgs(string msg, MsgType type) 65 { 66 this._message = msg; 67 this._type = type; 68 } 69 } 70 71 class MsgEvnet 72 { 73 public delegate void MsgEvent(object sender, MsgEventArgs msg); 74 public static event MsgEvent msgEvent; 75 76 public static void SendMsg(string msg) 77 { 78 if (MsgEvnet.msgEvent != null) 79 { 80 MsgEvnet.msgEvent(null, new MsgEventArgs(msg)); 81 } 82 } 83 84 public static void SendMsg(string msg, MsgType type) 85 { 86 if (MsgEvnet.msgEvent != null) 87 { 88 MsgEvnet.msgEvent(null, new MsgEventArgs(msg, type)); 89 } 90 } 91 92 public static void SendMsg(object sender, string msg) 93 { 94 if (MsgEvnet.msgEvent != null) 95 { 96 MsgEvnet.msgEvent(sender, new MsgEventArgs(msg)); 97 } 98 } 99 100 public static void SendMsg(object sender, string msg, MsgType type)101 {102 if (MsgEvnet.msgEvent != null)103 {104 MsgEvnet.msgEvent(sender, new MsgEventArgs(msg, type));105 }106 }107 }108 }
放弃的传递消息模式

下面这段代码之前放出来过（http://www.cnblogs.com/preacher/p/4105810.html），做了几点修改，计算的方式：根据每个正六边形的中心点，计算出下三边的相对位置然后绘制下三边。以下算法中，把之前的基类Control改为了Label，主要方便控件透明，Control为基类是不支持控件透明。

下面这段代码主要控制鼠标操作的事件，以及通过委托把消息传递出去。当鼠标指针靠近控件边缘并在1/8的相对区域内，会触发滑动地图的事件。

from窗体控件里面的东西相对来说比较简单了，主要是把通过委托的消息展示下，没什么难度，把设计器和后台代码合并了。

时间有限，篇幅有限，今天下午就敲了这么多，下次继续。（不过上午把设计文档写好了，按照步骤一点点的做吧）
这几段代码手打后没详细测试，可能会有问题，欢迎斧正。
