在编写那个烟花的程序（java），以下是对烟花进行绘制的代码，我是新手看不懂，请帮忙解释下呢··
就是找了三个随机数, r,g,b作为颜色的初始色彩,在三个数字上偏移, 得到相近的颜色.. 并画出来..
c语言放烟花代码
#include "stdlib.h"
#include "graphics.h"
#include "stdio.h"
#include "math.h"
#include "conio.h "
#define PI 3.1425926
main()
{
int gdriver=DETECT,gmode,errorcode;
int a[10],b[10],x,y,c,r,i,j,t;
double rad = 0.0;
/* initialize graphics and local variables */
initgraph(gdriver , gmode ,"");
/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error : %s/n",grapherrormsg(errorcode));
printf("Please any key to halt:");
getch();
exit(1); /* terminate with an error code */
}
randomize();
for(;!kbhit();)
{
x=rand()%500+100; /*随机中心坐标*/
y=rand()%300+100;
for(r = 0 ;r = 8 ; r++ ) /*烟花的大小设定*/
{
for(i = 0,rad = 0.0 ; rad 2*PI; rad += 0.78 ) /*设定坐标*/
{
a[i++] = x + (int)r *10* cos(rad);
b[ i ] = y + (int)r *10* sin(rad);
}
t = i;
for(i=1;it;i++)
{
c=rand()%13+1; /*各点的颜色随机*/
setcolor(c); /*功能:将当前图形屏幕的当前笔画颜色置为color.*/
circle(a[i],b[i],1);/* a[i],b[i] 为圆心 1 为半径 画圆 */
}

我的世界烟花怎么用命令方块生成有颜色和形状的烟花
摘自乐游网：
命令方块自定义烟花的方法：
这个不是刷烟花物品，而是直接从指令方块里放出烟花。好处是烟花可以全自定义。
这是2个烟花效果，是2个不同的指令方块刷出的。颜色什么可以全部自定义。
进入教程。首先是教大家如何刷出一个最基础的烟花。指令是：
/summon FireworksRocketEntity ~ ~1 ~
复制代码
大家可以把这条指令打入指令方块然后激活，但只会刷出一个烟花的样子，而不会产生任何爆炸，因为指令里还未调制任何爆炸效果。基础的/summon指令我就不多说了，大家只要记住FireworksRocketEntity就好了。之后就是加入点NBT，让烟花拥有自定义爆炸效果。指令：
/summon FireworksRocketEntity ~ ~1 ~
{LifeTime:30,FireworksItem:{id:401,Count:1,tag:{Fireworks:
{Explosions:[{Flicker:10,Trail:1,Type:3,Colors:[0],FadeColors:[0]}]}}}}
当大家把这条指令打入指令方块并且激活后，会刷出一个黑色的苦力怕的脸。接下来来讲解下NBT：
LifeTime：烟花的飞行延迟，也就是烟花飞上去没爆炸前的时间。调成20就是一秒。
FireworksItem:{id:401,Count:1,tag:{Fireworks:：这是固定要打的。意思就是让指令方块知道是烟花。
Explosions：烟花的爆炸效果。这行是重点，控制烟花的颜色，效果，花样什么的。
Flicker：烟花即将结束后的延迟。这行可以随便写，没延迟就是0。大家可以写着看看效果，就知道具体意思了。
Trail：烟花内部的效果。如果内部是空心的，就写0，内部有烟花效果，就是1。同Flicker，大家可以调的自己看看效果。
Type：烟花爆炸效果种类，一共有5种。帖子下面会解释。
Colors：烟花的颜色。这个是用RGB转换DEC，较复杂。帖子下面会讲。
FadeColors：烟花即将结束后转换的颜色。原理同Colors。
虽然有很多的NBT，但是会英文就很简单了。Flicker和Trail较难解释，需要玩家自己实验。
接下来说说烟花效果，也就是Type里面写的。一共有5种，所以后面就写0-4。
种类：
0 - 小球爆炸。
1 - 大球爆炸。
2 - 星型爆炸。
3 - 苦力怕脸型爆炸。
4 - 扩散型爆炸。
当然大家也可以上Wiki看烟花效果。已上图的效果都带有Flicker:10和Trail:1。
之后是教大家如何自定义烟花颜色，也就是Colors和FadeColors这2个NBT用的。前面我写的都是0，也就是黑色。计算颜色有一种特殊的公式：
B+256*G+65536*R = x
公式里的RGB就是颜色属性。R是红色，G是绿色，B是蓝色。大家可以用Photoshop之类的获得一个颜色的RGB值。
之后举个例子：如果要一个绿色的烟火，那就是红色和蓝色都是0，绿色是255 （颜色最高属性是255），那么公式就是：
0+256*255+65536*0 = 65280
于是知道数值了后就可以写入了。比如：Colors:[65280],FadeColors:[0]。大家看到本人FadeColors后面写的还是0，因为本人要让烟花首先是绿色，然后再转换成黑色。当然，如果要全都是绿的话就2个全部写65280。之后算法就一样了。但是黑色的就是0，白色的话就是RGB都是255，算出来是。不知道颜色的RGB的话，那就可以用Photoshop或者Windows系统自带的画图，可以看出RGB属性。发几个常用的：
蓝色：255
白色：
黑色：0
绿色：65280
红色：
注意：如果要多个颜色，直接括号分开就好了。比如：Colors:[255,]。
之后是如果同时刷出多个爆炸效果，也就是同一个烟花有多个效果。指令：
/summon FireworksRocketEntity ~ ~1 ~
{LifeTime:30,FireworksItem:{id:401,Count:1,tag:{Fireworks:
{Explosions:[{Flicker:10,Trail:1,Type:3,Colors:[0],FadeColors:[0]},
{Flicker:10,Trail:0,Type:1,Colors:[],FadeColors:[]}]}}}}
大家看见，只要把Explosion后面的NBT重复就好了。当大家分解完我这条指令后，效果应该是：黑色的苦力怕脸，外面包着白色的球体。当然，想有多少爆炸效果就有多少爆炸效果，都是复制粘贴的活。
