游戏资源及代码生成
一、资源及c++代码生成
这里使用c#.net读写Excel及生成c++代码。
1.Excel读写及生成资源
需要添加Excel组件，暂时没有关闭excel进程的方法。
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Threading.Tasks; 6 7 using System.IO; 8 9 using Excel = Microsoft.Office.Interop.Excel; 10 using Forms = System.Windows.Forms; 11 12 namespace ResHelper 13 { 14 class ExcelHelper 15 { 16 private string _filepath; 17 private Excel.Application _app; // excel app 18 private Excel.Workbook _workbook; 19 private Excel.Worksheet _worksheet; 20 21 public bool Open(string filepath) 22 { 23 try 24 { 25 _filepath = filepath; 26 27 _app = new Excel.Application(); 28 _workbook = _app.Workbooks.Open(filepath, Type.Missing, Type.Missing, Type.Missing 29 , Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing 30 , Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 31 _worksheet = (Excel.Worksheet)_workbook.Worksheets[1]; 32 33 } 34 catch (System.Exception) 35 { 36 Forms.MessageBox.Show("打开Excel文件失败!"); 37 return false; 38 } 39 finally 40 { 41 } 42 return true; 43 } 44 45 public bool Create(string filepath) 46 { 47 try 48 { 49 _filepath = filepath; 50 _app = new Excel.Application(); 51 _workbook = _app.Workbooks.Open(filepath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, 52 Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, 53 Type.Missing, Type.Missing, Type.Missing); 54 } 55 catch (System.Exception) 56 { 57 58 } 59 finally 60 { 61 } 62 63 return true; 64 } 65 66 public string Cells(int row, int col) 67 { 68 if (row < 0 || col < 0) 69 { 70 Forms.MessageBox.Show("请输入正确的Excel某项的行号与列号，不能为负数!"); 71 } 72 return ((Excel.Range)_worksheet.Cells[row][col]).Text.ToString(); 73 } 74 75 public void Cells(int row, int col, string content) 76 { 77 if (row < 0 || col < 0) 78 { 79 Forms.MessageBox.Show("请输入正确的Excel某项的行号与列号，不能为负数!"); 80 } 81 _worksheet.Cells[row, col] = content; 82 } 83 84 public void Save(string filepath) 85 { 86 try 87 { 88 _worksheet.SaveAs(filepath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, 89 Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 90 91 } 92 catch (System.Exception) 93 { 94 95 } 96 finally 97 { 98 } 99 100 } 101 102 public void Close() 103 { 104 try 105 { 106 _app.Workbooks.Close(); 107 108 } 109 catch (System.Exception) 110 { 111 112 } 113 finally 114 { 115 _workbook = null; 116 _worksheet = null; 117 _app = null; 118 GC.Collect(); 119 } 120 121 } 122 123 public void ToRes() 124 { 125 if (string.IsNullOrEmpty(_filepath)) 126 { 127 Forms.MessageBox.Show("没有载入Excel文件！"); 128 return; 129 } 130 string txtpath = _filepath; 131 txtpath = txtpath.Substring(txtpath.LastIndexOf('\\') + 1); 132 txtpath = txtpath.Substring(0,txtpath.LastIndexOf('.') + 1); 133 txtpath += "res"; 134 txtpath = "./res/" + txtpath; 135 136 FileStream file = new FileStream(txtpath, FileMode.Create, FileAccess.Write); 137 try 138 { 139 int colnum = 0; 140 string text; 141 for (int i = 1; i < 100; ++i) 142 { 143 text = Cells(i, 1); 144 if (string.IsNullOrEmpty(text)) break; 145 colnum += 1; 146 } 147 if(colnum<1) 148 { 149 Forms.MessageBox.Show("没有列头，数据格式有误!"); 150 return; 151 } 152 string line, space = ""; 153 for(int i = 0; i<colnum; ++i) 154 { 155 space += "\t"; 156 } 157 158 159 using (StreamWriter writer = new StreamWriter(file)) 160 { 161 // 从3行开始才是数据 1.是表头 2.是备注 162 for (int row = 3; row < 10000; ++row) 163 { 164 line = ""; 165 for (int col = 1; col <= colnum; ++col) 166 { 167 text = Cells(col, row); 168 if (text.IndexOf('\t', 0) > 0) 169 { 170 Forms.MessageBox.Show("内容中不能含有tab表格符!"); 171 break; 172 } 173 text = text.Replace("\t", ",,"); 174 line += text + "\t"; 175 } 176 // 从该项开始没有数据 177 if (line == space) break; 178 line = line.Substring(0,line.LastIndexOf('\t')); 179 line += "\n"; 180 int len = line.Length; 181 writer.Write(line); 182 } 183 184 writer.Flush(); 185 writer.Dispose(); 186 writer.Close(); 187 } 188 } 189 catch (System.Exception e) 190 { 191 Forms.MessageBox.Show(e.Message); 192 return; 193 } 194 finally 195 { 196 file.Dispose(); 197 file.Close(); 198 } 199 } 200 } 201 }

二、装载资源的dll
有了上述工具生成res资源及c++数据结构后，再写一个通用的res资源读取的c++ dll工程即可。
1.字符串转换
1 /*------------------------------------------------------------------ 2 // 著作版权：Copyright (C) liuxb 3 // 创建时间：[liuxb|20130920] 4 // 功能描述：字符串转换 5 // 6 // 修改时间： 7 // 修改描述： 8 // 9 //----------------------------------------------------------------*/ 10 11 #pragma once 12 13 #include <stdlib.h> 14 15 // 字符串转换 16 struct string_helper 17 { 18 static int to_int(const char* value) { return atoi(value); } 19 20 static int to_long(const char* value) { return atol(value); } 21 22 static double to_double(const char* value) { return atof(value); } 23 24 // 从text中获取以c分隔的前半段字符串并写入buffer 25 // 返回src_text后半段字符串 26 static char* split(char* text, int text_len, char c, char* buffer); 27 };
1 #include "stdafx.h" 2 #include "convertion.hpp" 3 4 #include <string.h> 5 #include <stdio.h> 6 7 char* string_helper::split(char* text, int text_len, char c, char* buffer) 8 { 9 char* end = text; 10 for(int i = 0; i<text_len; ++i, ++end) 11 { 12 if(end[0] == c) 13 { 14 memcpy(buffer, text, end-text); 15 return end + 1; 16 } 17 } 18 memcpy(buffer, text, text_len); 19 return 0; 20 }
2.资源容器模板
1 /*------------------------------------------------------------------ 2 // 著作版权：Copyright (C) liuxb 3 // 创建时间：[liuxb|20130920] 4 // 功能描述：读入res资源转换成对象数组 5 // 6 // 修改时间： 7 // 修改描述： 8 // 9 //----------------------------------------------------------------*/ 10 11 #pragma once 12 13 #include <vector> 14 #include <string> 15 #include <algorithm> 16 #include <fstream> 17 18 using std::vector; 19 using std::string; 20 21 // 资源集 22 template<typename Data> 23 class resource_set 24 { 25 typedef vector<Data> vdata; 26 public: 27 typedef typename vdata::value_type value_type; 28 typedef typename vdata::iterator iterator; 29 public: 30 resource_set() 31 { 32 m_vdata = new vdata; 33 } 34 35 ~resource_set() 36 { 37 delete m_vdata; 38 } 39 40 public: 41 // 加载资源 42 bool load_resource(const char* resource_path) 43 { 44 std::ifstream file(resource_path, std::ios::binary); 45 if(!file) return false; 46 string line; 47 while (getline(file, line)) 48 { 49 value_type data(line.c_str()); 50 m_vdata->push_back(data); 51 } 52 return true; 53 } 54 55 // 查找资源 56 value_type* find(int id) 57 { 58 value_type data(id); 59 vdata::iterator it = std::find(m_vdata->begin(), m_vdata->end(), data); 60 if(it == m_vdata->end()) return 0; 61 return &(*it); 62 } 63 64 vdata& datas() { return *m_vdata; } 65 iterator begin() { return m_vdata->begin(); } 66 iterator end() { return m_vdata->end(); } 67 68 private: 69 vdata* m_vdata; 70 };
3.根据资源数据结构声明具体的资源容器导出类
1 // 下列 ifdef 块是创建使从 DLL 导出更简单的 2 // 宏的标准方法。此 DLL 中的所有文件都是用命令行上定义的 RES_EXPORTS 3 // 符号编译的。在使用此 DLL 的 4 // 任何其他项目上不应定义此符号。这样，源文件中包含此文件的任何其他项目都会将 5 // RES_API 函数视为是从 DLL 导入的，而此 DLL 则将用此宏定义的 6 // 符号视为是被导出的。 7 8 #pragma once 9 10 #ifdef RES_EXPORTS 11 #define RES_API __declspec(dllexport) 12 #else 13 #define RES_API __declspec(dllimport) 14 #endif 15 16 #include "resource_set.hpp" 17 18 #include "adt\npc_talk_dt.h" 19 #include "adt\task_dt.h" 20 21 22 class RES_API npc_talk_sc : public resource_set<npc_talk_dt> {}; 23 24 class RES_API task_sc : public resource_set<task_dt> {};
记得在dllmain.cpp中添加res.h头文件。
