视频：【课设拯救计划/直播回放】C++打地鼠游戏一小时极限开发（完整版）_哔哩哔哩_bilibili
创建几个全局变量：
IMAGE img_menuBackground; //主菜单背景图
IMAGE img_mole; //地鼠图片
IMAGE img_empty; //坑位图片
IMAGE img_hammer_idle; //默认状态锤子
IMAGE img_hammer_down; //敲击状态锤子bool is_quit = false; //游戏是否退出
bool is_satrt = false; //游戏是否开始IMAGE img_menuBackground; //主菜单背景图
IMAGE img_mole; //地鼠图片
IMAGE img_empty; //坑位图片
IMAGE img_hammer_idle; //默认状态锤子
IMAGE img_hammer_down; //敲击状态锤子bool is_quit = false; //游戏是否退出
bool is_satrt = false; //游戏是否开始创建一个窗口：
int main()
{initgraph(800, 950);hwnd = GetConsoleWindow(); // 获取控制台窗口句柄while (!is_quit) {FlushBatchDraw();}EndBatchDraw();return 0;
}加载资源
void load_resource()
{loadimage(&img_menu,_T("resources/menu.jpg"));loadimage(&img_mole, _T("resources/mole.jpg"));loadimage(&img_empty, _T("resources/empty.jpg"));loadimage(&img_hammer_idle, _T("resources/hammer_idle.jpg"));loadimage(&img_hammer_down, _T("resources/hammer_down.jpg"));mciSendString(_T("open resources/bgm.mp3 alias bgm"), NULL, 0, NULL);mciSendString(_T("open resources/hit.mp3 alias hit"), NULL, 0, NULL);
}创建地图
bool map[4][4] = {{false,false,false,false},{false,false,false,false},{false,false,false,false},{false,false,false,false},
};
int idx, idy; //当前地鼠所在位置false代表当前位置没有地鼠。
定义地鼠的坐标位置，锤子的坐标 ，砸中地鼠的得分，锤子的状态：
int idx, idy; //当前地鼠所在位置
bool is_hammer_down; //锤子是否被按下
POINT pos_hammer = { 0,0 }; //锤子的坐标
int score; //得分逻辑部分
创建四个函数
void input_menu_scence(const ExMessage& msg)
{}
void input_game_scence(const ExMessage& msg)
{}
void render_menu_scence(const ExMessage& msg)
{putimage(0, 0, &img_menu);
}
void render_game_scence(const ExMessage& msg)
{}
void update_game_scence(const ExMessage& msg)
{}菜单和进入游戏之间的逻辑
int main()
{.......
while (!is_quit) {ExMessage msg;while (peekmessage(&msg)){//如果当前未进入游戏，那么就进入菜单页面，否则就继续游戏if (!is_start){input_menu_scence(msg);}else{input_game_scence(msg);}}setbkcolor(RGB(251,251,251));cleardevice(); //清空绘图窗口//如果当前没有开始游戏，那么就进入菜单页面，否则就继续游戏if (!is_start){render_menu_scence(msg);}else{render_game_scence(msg);}FlushBatchDraw();Sleep(5);}}设置按钮布局和样式以及功能
布局和样式
Button()
{
//设置按下按钮时的样式
void on_render()
{setlinecolor(RGB(20,20,20)); //设置按钮边框为深灰色if (is_pushed){setfillcolor(RGB(185,185,185)); //设置按下按钮时背景色为灰色}else if (is_hovered){setfillcolor(RGB(235,235,235)); //设置鼠标悬停时背景色为灰色}else{setfillcolor(RGB(205,205,205)); //设置普通状态下背景色为白色}fillrectangle(_rect.left, _rect.top, _rect.right, _rect.bottom); //绘制矩形setbkmode(TRANSPARENT); //设备背景：透明settextcolor(RGB(20,20,20)); //字体颜色drawtext(_text.c_str(), &_rect, DT_CENTER | DT_SINGLELINE | DT_VCENTER); //绘制文本//水平居中 单行显示 垂直居中
}
}调用
main.cpp
#include"button.h"//构建三个自定义按钮类按钮对象
Button btn_play(L"开 始 游 戏", {350,450,500,500}); //开始按钮
Button btn_info(L"游 戏 介 绍", { 350,500,500,550 });
Button btn_quit(L"退 出 游 戏", { 350,550,500,600 }); int main()
{//对三个按钮通过调用on_input()进行设置布局和样式
void input_menu_scence(const ExMessage& msg)
{btn_play.on_input(msg);btn_info.on_input(msg);btn_quit.on_input(msg);
}//绘制这三个按钮
void render_menu_scence(const ExMessage& msg)
{putimage(0, 0, &img_menu);btn_play.on_render();btn_info.on_render();btn_quit.on_render();
}return 0;
}
按钮绑定回调函数
在初始化的时候就给按钮绑定回调函数。
button.h
class Button
{
public:Button(const std::wstring& text,const RECT& rect ){
//设置按钮的回调函数void set_on_click(const std::function<void()>& func){on_click = func;}
}main函数调用，单击按钮播放背景音乐
介绍按钮弹出信息弹窗。
退出按钮退出程序。
main.cpp
int main()
{
.....load_resource();btn_play.set_on_click([&] {is_start = true;mciSendString(_T("play bgm"),NULL,0,NULL);});btn_info.set_on_click([&] {SetForegroundWindow(hwnd); // 确保当前窗口在最前面MessageBox(hwnd,_T("用鼠标左键点击地图上的空白位置，即可放置地鼠。\n\n游戏过程中，地鼠会自动向空白位置移动，\n\n玩家需要用锤子将地鼠击中，\n\n击中地鼠后，游戏将会加1分。\n\n游戏结束时，玩家可以选择重新开始或退出游戏。"),_T("游戏说明"),MB_OK);});btn_quit.set_on_click([&] {is_quit = true;});BeginBatchDraw();......
}游戏主场景
砸中地鼠得分，没砸中减分
void input_game_scence(const ExMessage& msg)
{switch(msg.message){//更新鼠标位置case WM_MOUSEMOVE:pos_hammer.x = msg.x;pos_hammer.y = msg.y;break;//鼠标左键按下case WM_LBUTTONDOWN:{is_hammer_down = true; //锤子被按下了static const int width_mole=img_mole.getwidth();static const int height_mole = img_mole.getwidth();if (map[idx][idy]&&pos_hammer.x>=idx*width_mole+ offset_map.x&&pos_hammer.x <= (idx+1) * width_mole + offset_map.x&&pos_hammer.y >= idy * width_mole + offset_map.y&&pos_hammer.y <= (idy + 1) * width_mole + offset_map.y){score += 10;map[idx][idy] = false; //地鼠被击中mciSendString(_T("play hit"), NULL, 0, NULL); //播放击中音效}else{is_hammer_down = false; //鼠标抬起切换为锤子默认状态score -= 10;}break;//鼠标左键松开case WM_LBUTTONUP:{is_hammer_down = false; //锤子松开了}break;//键盘按下default:break; }}
}游戏更新
void update_game_scence(const ExMessage& msg)
{static int timer = 0;timer = timer++ % 100; //每隔100帧触发一次地鼠移动if (timer == 0){map[idx][idy] = false; //当前位置没有地鼠idx = rand() % 4; //随机生成地鼠位置idy = rand() % 4;while (map[idx][idy]) //如果随机生成的位置已经有地鼠，则重新生成{idx = rand() % 4;idy = rand() % 4;}map[idx][idy] = true; //随机生成地鼠}
}游戏渲染
void render_game_scence(const ExMessage& msg)
{//绘制地图static const int width_mole = img_mole.getwidth();std::cout<<"width_mole:"<<width_mole<<std::endl;static const int height_mole = img_mole.getheight();for (int i = 0; i < 4; i++){for (int j = 0; j < 4; j++){std::cout<<"map[i][j]:" << map[i][j] <<std::endl;if (map[i][j]) //当前位置有地鼠{putimage(i * width_mole + offset_map.x, j * height_mole + offset_map.y, &img_mole); //绘制地鼠std::cout<<"绘制地鼠成功"<<std::endl;}else{putimage(i * width_mole + offset_map.x, j * height_mole + offset_map.y, &img_empty); //绘制空白位置std::cout << "绘制地鼠失败" << std::endl;}}}//绘制锤子static const int width_hammer_idle = img_hammer_idle.getwidth();static const int height_hammer__idle = img_hammer_idle.getheight();static const int width_hammer_down = img_hammer_down.getwidth();static const int height_hammer_down = img_hammer_down.getheight();if (is_hammer_down) //锤子被按下{putimage(pos_hammer.x - width_hammer_down / 2, pos_hammer.y - height_hammer_down / 2, &img_hammer_down);}else{putimage(pos_hammer.x - width_hammer_down / 2, pos_hammer.y - height_hammer_down / 2, &img_hammer_idle);}//绘制游戏得分std::cout<<"score:"<<score<<std::endl;std::wstring score_str = L"游戏得分: "+std::to_wstring(score);settextstyle(25,0,_T("黑体"));settextcolor(RGB(255,15,105));outtextxy(10, 10, score_str.c_str());
}此时有个问题，因为我的锤子的图片是png格式的，png的透明背景，在eaxys里会被处理为黑色背底：
我们这个时候就不用putimage()函数，用我们自己定义的函数：
void transparentimage3(IMAGE* dstimg, int x, int y, IMAGE* srcimg) //新版png
{HDC dstDC = GetImageHDC(dstimg);HDC srcDC = GetImageHDC(srcimg);int w = srcimg->getwidth();int h = srcimg->getheight();BLENDFUNCTION bf = { AC_SRC_OVER, 0, 255, AC_SRC_ALPHA };AlphaBlend(dstDC, x, y, w, h, srcDC, 0, 0, w, h, bf);
