c++控制台做的基于粒子系统的礼花组字：春节快乐

圣手书生，恭祝大家，春节快乐

代码并不复杂，这里分别讲解一下。

粒子系统的设计：

struct Cell{int x, y, tx, ty, len;int s, e;int color;void show(int t){if (t>=s and t<=e){int x1= x+ (tx-x)*(t-s)/(e-s);int y1= y+ (ty-y)*(t-s)/(e-s);if (x1>=0 && y1>0 && y1<MAXY){setColor(color);gotoxy(x1,y1);cout << "*";}}if (t>=s+len and t<=t+len){int tt= t-len;int x1= x+ (tx-x)*(tt-s)/(e-s);int y1= y+ (ty-y)*(tt-s)/(e-s);if (x1>=0 && y1>0 && y1<MAXY){gotoxy(x1,y1);cout << " ";}}}
} cells[2000];

粒子的信息基本参数：起点x,y，终点x,y，有效长度，可见时间，消失时间，颜色。

只有一个控制粒子显示的函数：当粒子在时间区域内，显示一个星号作为粒子的形态，在有效长度之后，显示空格以隐藏它。

显示所有粒子，只通过这样一个非常简单的函数：

void show(){int total= 100;for (int t=0; t<=total; t++){for (int i=0; i<n; i++){cells[i].show(t);}Sleep(100);}
}

添加圆形礼花：

void addCircle(int cx, int cy, int start, int color){int r= 20;double pi=3.14;for (int i=0; i<10; i++){int j= i*36;int x1= cx+ r*cos(j*pi/180);int y1= cy+ r*sin(j*pi/180);cells[n++]={cx, cy, x1, y1, 5, start, start+10, color};}addCell(cx, cy+20, cx, cy, 3, start-7, start, color);
}

添加字形礼花：

void addWord(int cx, int cy, int start, int color, int zi){for (int i=0; i<16; i++){int a= data[zi][i];for (int j=0; j<16; j++){int b= a%2;a/=2;if (b>0) {addCell(cx, cy, cx+8-j, cy-8+i, 2, start, start+15, color);addCell(cx+8-j, cy-8+i, cx+8-j, cy-8+i, 8, start+15, start+25, color);}}}addCell(cx, cy+20, cx, cy, 3, start-7, start, color);
}

字形礼花涉及了字库的信息，这里为了让代码简洁，直接将用到的字提取为数组，嵌入到了代码中。

int data[20][16]={{0,16368,2080,1088,640,256,1728,6192,57614,256,8176,256,256,256,32764,0},{16,248,16128,256,256,16376,256,256,256,65534,256,256,256,256,1280,512},{544,528,520,16352,544,544,544,544,65532,516,516,516,516,552,528,512},{1088,1088,16376,1088,1088,65534,1088,2080,4624,8712,49702,4752,4680,8776,2560,1024},{8192,5116,4612,64004,2564,4612,5116,14480,21648,38032,4240,4370,4370,4626,5134,6144},{256,256,256,256,256,65534,256,256,640,640,1088,1088,2080,4112,8200,49158},{512,256,32766,16386,32772,32764,512,3336,29072,672,3264,29088,1688,6278,57984,256},{256,256,32764,256,16376,512,65534,2080,4112,12264,51238,2080,4064,2080,2080,4064},{2080,2080,65534,2080,2080,0,32760,520,520,520,520,592,544,512,512,512},{4160,4160,4160,5112,6216,21576,20552,20552,38910,4160,4256,4256,4368,4368,4616,5126},{32,240,7936,4096,4352,8448,8448,16380,256,2336,2320,4360,8452,16644,1280,512},{256,4352,4352,4352,16380,8448,16640,33024,256,16376,256,256,256,256,65534,0} };

最后，主程序进行组装：

int main(){hideCursor();addCircle(20, 5, 12, 9);addCircle(40, 7, 13, 10);addCircle(80, 7, 14, 11);addCircle(60, 5, 14, 12);addWord(20, 10, 32, 14, 0);addWord(40, 12, 33, 14, 1);addWord(60, 10, 34, 14, 2);addWord(80, 12, 34, 14, 11);addWord(20, 12, 52, 13, 3);addWord(40, 10, 53, 13, 4);addWord(60, 12, 54, 13, 5);addWord(80, 10, 54, 13, 6);addWord(25, 12, 72, 12, 7);addWord(45, 10, 73, 12, 8);addWord(65, 12, 74, 12, 9);addWord(85, 10, 74, 12, 10);show();return 0;
}

4个圆形礼花，12个字形礼花。
