Stars

[hawee8]

Hi
Im trying to have a background picture of a city and make stars in the sky flashing
can anyone tell me how to do this?
step by step please =P

add this code for the stars
and just create a small movieclip with a white circle put this mc on the stage and name its instance "star".

stars = 200;
//amount of stars to be created
starsRandomSize = 10;
//highest size a star can be in pixels
alphaSpeed = 5;
// how fast the star fades
function createStars(amountOfStars,starSize) {
for(i=0;i<amountOfStars;i++) {
_root.duplicateMovieClip("star","star"+i,i);
swid = Stage.width;
shei = Stage.height;
eval(["star"+i])._x = random(swid);
eval(["star"+i])._y = random(shei);
eval(["star"+i])._width = eval(["star"+i])._height = random(starSize)+5;
eval(["star"+i])._alpha = random(101);
eval(["star"+i]).rndNum = random(2);
eval(["star"+i]).starDown = (eval(["star"+i]).rndNum=0) ? true : false;
}
}
createStars(stars,starsRandomSize);
function changeStarAlpha(speed) {
for(i=0;i<amountOfStars;i++) {
if(eval(["star"+i])._alpha<=30) {
eval(["star"+i]).starDown = false;
}
if(eval(["star"+i])._alpha>=100) {
eval(["star"+i]).starDown = true;
}
if(eval(["star"+i]).starDown) {
eval(["star"+i])._alpha -= speed;
}else{
eval(["star"+i])._alpha += speed;
}
}
}
this.onEnterFrame = function() {
changeStarAlpha(alphaSpeed);
}; 

sorry if my code is a little sketchy i am at work right now i will test it later at home if it doesn't work for you
