Hey there:  
I like doing stuff like that:beam:

As far as I know, there isn’t really a tutorial on it. I made the fla called thunderstars to simulate a warp effect. You can change the code around and the apperance of the star/raindrop. It doesn’t use any tweens.  
The other one (realLightning) I got off the internet I think at [FlashKit.com](http://FlashKit.com).  
Good luck!!

2 steps

1. Make a movie clip named rain (it should represent a rain drop)

2. make some AS which duplicates the movie clip a certain amount of times, give it a random \_x and a \_y that is above the screen. then apply some direction to the clips. the code should look similar to the one below:

[AS]rain.\_visible = false;  
amountOfRain = 100  
moveMe = function () {  
this.\_x += this.dx;  
this.\_y -= this.dy;  
this.\_alpha -= 2;  
if (this.\_y\>400) {  
this.dx = Math.random()_3;  
this.dy = Math.random()_-8-4;  
this.\_alpha = 100;  
this.\_x = Math.random()\*550;  
this.\_y = 0;  
}  
if (this.\_x\>550) {  
this.dx = Math.random()_3;  
this.dy = Math.random()_-8-4;  
this.\_alpha = 100;  
this.\_x = Math.random()\*550;  
this.\_y = 0;  
}  
};  
for (i=0; i\<amountOfRain; i++) {  
nm = “rain” add i;  
rain.duplicateMovieClip(nm, i);  
scale = Math.random()\*80+50;  
\_root[nm].\_xscale = scale;  
\_root[nm].\_yscale = scale;  
\_root[nm].dx = Math.random()_3;  
\_root[nm].dy = Math.random()_-8-4;  
\_root[nm].onEnterFrame = moveMe;  
\_root[nm].\_x = Math.random()_550;  
\_root[nm].\_y = Math.random()_-400;  
}[/AS]

have phun 🙂

p.s.  
dx represents wind, dy is the downward speed, amountOfRain is how many times the rain MC should be duplicated (i recomend under 200) the “this.\_alpha -= 2” controls the speed at which the rain fades. anymore questions, ask me 😉
