Question

Помогите исправить код для снежинок. Нужно изменить направление движения что бы они не падали, а поднимались вверх

Вот код

</script>

<script language="JavaScript1.2">

grphcs=new Array(2)

Image0=new Image();

Image0.src=grphcs[0]="http://fantasyflash.ru/script/web/image/sneg1.gif";

Image1=new Image();

Image1.src=grphcs[1]="http://fantasyflash.ru/script/web/image/sneg1.gif";

Amount=25;

Ypos=new Array();

Xpos=new Array();

Speed=new Array();

Step=new Array();

Cstep=new Array();

ns=(document.layers)?1:0;

ns6=(document.getElementById&&!document.all)?1:0;

if (ns){

for (i = 0; i < Amount; i++){

var P=Math.floor(Math.random()*grphcs.length);

rndPic=grphcs[P];

document.write("<LAYER NAME='sn"+i+"' LEFT=0 TOP=0><img src="+rndPic+"></LAYER>");

}

}

else{

document.write('<div style="position:absolute;top:0px;left:0px"><div style="position:relative">');

for (i = 0; i < Amount; i++){

var P=Math.floor(Math.random()*grphcs.length);

rndPic=grphcs[P];//osw

document.write('<img id="si'+i+'" src="'+rndPic+'" style="position:absolute;top:0px;left:0px">');

}

document.write('</div></div>');

}

WinHeight=(ns||ns6)?window.innerHeight:window.document.body.clientHeight;

WinWidth=(ns||ns6)?window.innerWidth-70:window.document.body.clientWidth;//fantasyflash.ru

for (i=0; i < Amount; i++){

Ypos = Math.round(Math.random()*WinHeight);

Xpos = Math.round(Math.random()*WinWidth);

Speed= Math.random()*5+3;

Cstep=0;

Step=Math.random()*0.1+0.05;

}

function fall(){

var WinHeight=(ns||ns6)?window.innerHeight:window.document.body.clientHeight;

var WinWidth=(ns||ns6)?window.innerWidth-70:window.document.body.clientWidth;

var hscrll=(ns||ns6)?window.pageYOffset:document.body.scrollTop;

var wscrll=(ns||ns6)?window.pageXOffset:document.body.scrollLeft;

for (i=0; i < Amount; i++){

sy = Speed*Math.sin(90*Math.PI/180);

sx = Speed*Math.cos(Cstep);

Ypos+=sy;

Xpos+=sx;

if (Ypos > WinHeight){

Ypos=-60;

Xpos=Math.round(Math.random()*WinWidth);

Speed=Math.random()*5+3;

}

if (ns){

document.layers['sn'+i].left=Xpos;

document.layers['sn'+i].top=Ypos+hscrll;

}

else if (ns6){

document.getElementById("si"+i).style.left=Math.min(WinWidth,Xpos);

document.getElementById("si"+i).style.top=Ypos+hscrll;

}

else{

eval("document.all.si"+i).style.left=Xpos;

eval("document.all.si"+i).style.top=Ypos+hscrll;

}

Cstep+=Step;

}

setTimeout('fall()',20);

}

window.onload=fall

//-->

</script>
