C++小游戏之贪吃蛇

xiaoxiao2021-03-25 91

先奉上完整的项目源码：http://pan.baidu.com/s/1slxvMWl

用的是easy x 图形库，没有的话可以去官网下载最新版本，用vs2015选择win32控制台应用程序->空项目就可以了。

开始界面有游戏界面都是 640x480大小。效果如下：

鼠标移动到英文上，字母的颜色会发生改变，单击就可以进入，同时有背景音乐播放。

代码：

void StartWindow() { mciSendString(L"open ./风动草.mp3 alias bgm",0,0,0); mciSendString(L"play bgm repeat", 0, 0, 0); loadimage(&backImg, L"./image/1.jpg", 640, 480); //将图片加载到backImg loadimage(&gbkImg, L"./image/bk.jpg", 640, 480); loadimage(&foodImg,L"./image/apple.jpg",10,10); loadimage(&about, L"./image/about.jpg", 640, 480); loadimage(&lose, L"./image/lose.jpg", 640, 480); loadimage(&food2, L"./image/food2.jpg", 10, 10); putimage(0, 0, &backImg); MOUSEMSG msg = { 0 }; setbkmode(TRANSPARENT); //设置背景风格透明 settextstyle(40, 18, L"Ravie");//设置字体风格 while (1) { msg = GetMouseMsg(); if (msg.x >= 450 && msg.x <= 550 && msg.y >= 205 && msg.y <= 245) { settextcolor(RGB(255, 0, 0));//设置字体颜色 outtextxy(450, 205, L"Start"); } else if (msg.x >= 450 && msg.x <= 550 && msg.y >= 305 && msg.y <= 345) { settextcolor(RGB(255, 0, 0));//设置字体颜色 outtextxy(450, 305, L"About"); } else if (msg.x >= 450 && msg.x <= 550 && msg.y >= 405 && msg.y <= 445) { settextcolor(RGB(255, 0, 0));//设置字体颜色 outtextxy(450, 405, L"End"); } else { settextcolor(RGB(137, 57, 196));//设置字体颜色 outtextxy(450, 205, L"Start"); outtextxy(450, 305, L"About"); outtextxy(450, 405, L"End"); } switch (msg.uMsg) { case WM_LBUTTONDOWN: if (msg.x >= 450 && msg.x <= 550 && msg.y >= 205 && msg.y <= 245) { return; } else if (msg.x >= 450 && msg.x <= 550 && msg.y >= 405 && msg.y <= 445) { exit(0); } else if (msg.x >= 450 && msg.x <= 550 && msg.y >= 305 && msg.y <= 345) { AboutWindow(); StartWindow(); body(); } break; } } }About是游戏说明，里面有关于游戏的介绍和操作说明，点击back就可以返回到开始界面。效果如下：

代码：

void AboutWindow() { cleardevice(); putimage(0, 0, &about); while (1) { MOUSEMSG msg = { 0 }; setbkmode(TRANSPARENT); //设置背景风格透明 settextstyle(40, 18, L"Ravie");//设置字体风格 msg = GetMouseMsg(); if (msg.x >= 450 && msg.x <= 550 && msg.y >= 425 && msg.y <= 465) { settextcolor(RGB(255, 0, 0));//设置字体颜色 outtextxy(450, 425, L"Back"); } else { settextcolor(RGB(137, 57, 196));//设置字体颜色 outtextxy(450, 425, L"Back"); } switch (msg.uMsg) { case WM_LBUTTONDOWN: if (msg.x >= 450 && msg.x <= 550 && msg.y >= 425 && msg.y <= 465) { return; } break; } } }单击start进入游戏，效果如下：
