C语言实战之浪漫烟花表白程序.doc

创建win32控制台应用程序，选择空项目。创建完毕后，右击头文件新建一个头文件（.h）。名字写main.h然后在源文件新建一个C+文件（.cpp）。名字写main.cpp如图：然后在main.h里面写上如下代码：#include #include #include #include #include #include #pragma comment(lib,winmm.lib)#define PI3.1415926535#define NUM13 /烟花弹struct JETintx, y;/坐标inthx,hy; /最高点坐标boolshoot; /判断烟花弹是不是发射状态DWORD t1, t2, dt; /烟花弹发射的速度IMAGE img2; /图片2张 一明一暗的两张byte n : 1; /结构体 位段 变量 n 占用内存的一个位！jetNUM;/烟花struct FIREint r; /半径int maxr; /最大半径int x, y;/相对于窗口 中心点的坐标int cenx, ceny; /相对于图片本身 中心点的坐标int width, height; int xy240240; /图片 保存到一个像素矩阵。bool show;/是否绽放bool draw;/是否绘制DWORD t1, t2, dt;/爆炸的速度fireNUM;void Init(int i);void Load();void Chose(DWORD& t1);void Shoot();void Show(DWORD* pem);在main.cpp写上如下代码：/*表白浪漫烟花项目开发*主讲人:三黑之毅*最后修改：2019年3月20日*/#include main.hint main()/打开一个窗口 1200 800initgraph(1200, 800);srand(unsigned int)time(NULL);mciSendString(Lopen ./fire/千年.mp3 alias bgm, 0, 0, 0);mciSendString(Lplay bgm repeat, 0, 0, 0);DWORD t1 = GetTickCount();DWORD* pem = GetImageBuffer();for (int i = 0; i NUM; i+)Init(i);Load();BeginBatchDraw();while (1)Sleep(10);for (int clr = 0; clr 1000; clr+)for (int j = 0; j 2; j+)int px1 = rand() % 1200;int py1 = rand() % 800;if (py1 799)pempy1 * 1200 + px1 = pempy1 * 1200 + px1 + 1 = BLACK;Chose(t1);Shoot();Show(pem);FlushBatchDraw();return 0;/初始化 13个void Init(int i)/ 分别为：烟花中心到图片边缘的最远距离、烟花中心到图片左上角的距离 (x、y) 两个分量int r15 = 120, 120, 155, 123, 130, 147, 138, 138, 130, 135, 140, 132, 155, 145, 124 ;int x15 = 120, 120, 110, 117, 110, 93, 102, 102, 110, 105, 100, 108, 110, 145, 124 ;int y15 = 120, 120, 85, 118, 120, 103, 105, 110, 110, 120, 120, 104, 85, 145, 124 ;firei.width = 500;firei.height = 500;firei.maxr = ri;firei.cenx = xi;firei.ceny = yi;firei.show = false;firei.t1 = GetTickCount();firei.dt = 5;firei.r = 0;/初始化烟花弹的部分数据jeti.t1 = GetTickCount(); /定个时间点jeti.dt = rand() % 10; /0-9 msjeti.n = 0;jeti.shoot = false; /都是没有发射的。/加载图片void Load() /加载到哪里去？IMAGE fm, gm;loadimage(&fm, L./fire/flower.jpg, 3120, 240);for (int i = 0; i NUM; i+)SetWorkingImage(&fm); /fm去拿getimage(&gm,i*240, 0, 240, 240); /gmSetWorkingImage(&gm); /gm去拿for (int a = 0; a 240; a+)for (int b = 0; b 240; b+)firei.xyab = getpixel(a, b);/文件夹IMAGE sm;loadimage(&sm, L./fire/shoot.jpg, 200, 50);/保存在smfor (int i = 0; i 1) /每隔1个ms 产生一个烟花弹int n = rand() % NUM; /0-12if (jetn.shoot = false&firen.show = false) /非发射状态jetn.x = rand()%1200;jetn.y = rand() % 100 + 600; /600-699之间jetn.hx = jetn.x;jetn.hy = rand()%400;/0-399jetn.shoot = true; /发射状态putimage(jetn.x, jetn.y, &jetn.imgjetn.n, SRCINVERT);t1 = t2;void Shoot()for (int i = 0; i = jeti.dt&jeti.shoot=true)putimage(jeti.x, jeti.y, &jeti.imgjeti.n, SRCINVERT);if (jeti.y = jeti.hy)jeti.n+;/一闪一闪jeti.y -= 5; /上升/putimage(jeti.x, jeti.y, &jeti.imgjeti.n, SRCINVERT);if (jeti.y = jeti.hy) /到达最高点了/擦除烟花弹putimage(jeti.x, jeti.y, &jeti.imgjeti.n, SRCINVERT);/烟花弹最高点的 hx hy -烟花firei.x = jeti.hx;firei.y = jeti.hy;/改变烟花弹的状态jeti.shoot = false;firei.show = true;putimage(jeti.x, jeti.y, &jeti.imgjeti.n, SRCINVERT);jeti.t1 = jeti.t2;void Show(DWORD* pem)int dir16 = 5, 5, 5, 5, 5, 8, 25, 25, 25, 55, 55, 55, 55, 65, 65, 66 ;for (int i = 0; i firei.dt&firei.show = true)if (firei.r = firei.maxr - 1)firei.draw = false;Init(i);firei.t1 = firei.t2;if (firei.draw = true)/圆 PIfor (double a = 0; a 0 & x10 & y1 8) & 0xff;int r = firei.xyx1y1 16;int xx = (int)(firei.x + firei.r*cos(a);int yy = (int)(firei.y - firei.r*sin(a);if (r0x20 & g 0x20 & b 0x20 & xx 0 & xx0 & yy 800)pemyy * 1200 + xx = BGR(firei.xyx1y1);firei.draw = false;/*注：音乐：千年.mp3,自己去网上下载，然后放到程
