教你用for循环制作漂亮的烟花动态效果

for (i=1; i<=51; i++) {
daxiao = random(51)+50; //定义大小比例变量
duplicateMovieClip("yanhua", "yanhua"+i, i); //复制新实例
setProperty("yanhua"+i, _rotation, random(360)); //设置新实例随机旋转角度
setProperty("yanhua"+i, _alpha, random(100)); //设置新实例随机透明值
setProperty("yanhua"+i, _xscale, daxiao); //设置新实例随机缩放比例
setProperty("yanhua"+i, _yscale, daxiao);
yanse = new Color("yanhua"+i); //设置新实例颜色对象
yanse.setRGB(random(0xffffff)); //赋值为随机颜色
}
yanhua._alpha = 0; //实例本身设置为透明，使其不可见

j=1; //初始变量

attachMovie("hua", "hua"+j, j); //复制新实例，链接名称是刚才设置的！
_root["hua"+j]._x = random(450)+100; //设置新实例的随机坐标
_root["hua"+j]._y = random(350)+100;
j++; //变量递增

gotoAndPlay(2); //跳到帧2播放，使其不断的复制新实例
