flash as简单制作飘雪动画

不用任何元件，只用一帧，在flash8中就可以做出雪景画面。设背景为黑色，或导入一张你喜欢的图片做背景，复制狼蚁网站SEO优化的代码到场景的第一帧就行了。 fallSnow(this,150,[600,375]);
functionfallSnow(path,num,size){
for(vari=0;i<num;i ){
path.createEmptyMovieClip("xue" i,i);
varmc=path["xue" i];
mc._x=random(size[0]);
mc._y=random(size[1]);
mc.ro=[1,-1][random(2)];
mc.xtime=random(20);
mc.startTime=0;
mc.id=Math.pow(i,1/2);
createSnow(mc,mc.id/2.5,"0xffffff",20mc.id);
}
varloop=function(){
updateAfterEvent();
for(vari=0;i<num;i ){
varmc=path["xue" i];
mc._rotation =mc.ro5;
mc._x =mc.idmc.ro/10;
mc._y =mc.id/2;
mc.startTime ;
scanTar(mc);
scanEdge(mc,size);
}
};
varinterval=setInterval(loop,10);
}
functioncreateSnow(mc,radius,c,alpha){

moveTo(0,-radius);

lineTo((radius/5)Math.sin(a1),-(radius/5)Math.cos(a1));
