某人让我发的，不过源码要等一会发，感觉有BUG，一会儿吃完饭再改改，御坂御坂说道

补充：修改了一下，不然没有VC2005的人运行不了


-----------------
再补充：
这里是新版本的程序：

以下是源代码：

#define _GRAPHICS_LIB_LINK_ 1
#include"yzfy_graphics.h"
#include"yzfy_dos.h"

#define MAXSNOW 500
struct SNOW
{
    int n;
    int lx, ly;
    int color;
    double x;
    double y;
    double cx;
    double dcx;
    double vx;
    double vy;
    double k;
};

const int sc_width = 640;
const int sc_height = 480;

void InitSnow(struct SNOW *snow)
{
    double vx = 0.5;
    double fvx = 0.5;
    double vy = (double)random(1000) / 1000;
    snow->x = random(sc_width);
    snow->y = 0;
    snow->cx = snow->x;
    snow->dcx = (double)random(1000) / 1000 * 2 * vx - vx;
    snow->k = (double)random(1000) / 1000 * -0.001;
    snow->vx = (double)random(1000) / 1000 * 2 * fvx - fvx;
    snow->vy = vy * 2.0 + 0.5;

    snow->color = (int)(192 * vy) + 64;
    snow->color = (((snow->color<<8) | snow->color) << 8) | snow->color;
}

void MoveSnow(struct SNOW *snow, double dt)
{
    double d = dt * 60 / 1000;

    putpixel(snow->lx, snow->ly, 0);

    snow->x += snow->dcx * d;
    snow->cx += snow->dcx * d;
    snow->y += snow->vy * d;

    if (snow->y > sc_height)
        InitSnow(snow);

    snow->lx = (int)snow->x;
    snow->ly = (int)snow->y;
    putpixel(snow->lx, snow->ly, snow->color);
}

int __stdcall OnUpdate(void* param, float ms)
{
    struct SNOW* snow = (struct SNOW *)param;
    int i;
    for (i = 1; i <= snow->n; i++)
    {
        snow[i].vx += (snow[i].x - snow[i].cx) * snow[i].k * 0.99;
        snow[i].x += snow[i].vx;
    }
    return 0;
}
int __stdcall OnRender(void* param, float ms)
{
    int i;
    for (i = 1; i <= ((struct SNOW*)param)->n; i++)
        MoveSnow((struct SNOW*)param+i, ms);
    return 0;
}

int main()
{
    {
        int g = TRUECOLORSIZE, m = sc_width | (sc_height << 16);
        initgraph(&g, &m, "Snow");
        randomize();
    }
    {
        struct SNOW snow[MAXSNOW+1];
        int i;
        snow[0].n = MAXSNOW;
        for (i = 1; i <= MAXSNOW; i++)
        {
            InitSnow(snow + i);
            snow[i].y = random(sc_height);
        }
        ege_gameloop(OnUpdate, snow, 60, OnRender, snow, 0);
    }

    closegraph();
    return 0;
}

至于代码所用到的库，请自己下载吧，御坂说

御姐的贴 狂顶

看错了，原来要等一会发的啊。

不错哦

yzfy_graphics.initgraph
yzfy_graphics.random
yzfy_gra.closegraph
yzfy_gra.setfillstyle
yzfy_gra.initgraph
yzfy_gra.putpixel
yzfy_gra.ege_gameloop

这个是谁的小短裤哇

御姐，很崇拜你哦

我用学姐的图形库写的，写的太乱了，代码还在修改中，御坂回答道

支持下

源码呢？
