Hi,

Would anyone be interested is a little Actionscript battle? I was thinking about mouse trailers because they are easy to make and you can get some really nice effects.

Tweens would be allowed, but no imported graphics or things like that…

If some of you are interested but need a script to get started, I (or anyone else) can provide a quick tute on mouse trailers.

I hope some of the mods will be interested too, I know we have a few masters… (Dan, Thor :bad: )

Cheers.  
pom :love:

I’ve never taken part in a battle before, but here goes!

PS. That means “yes”

Can we import grafix and trace bitmap?

Nope, nothing external 🙂

RussianBeer \>\> The basis: Let’s say you have a clip in your library with the linkage name “theClip”. First step:

```auto
this.onEnterFrame = function(){
i++;
var mc = this.attachMovie("theClip","theClip"+i,i);
mc._x = _xmouse;
mc._y = _ymouse;
}

```

You attach a clip at the position of the mouse onEnterFrame.

</div>

Next step: we add an enterFrame to the created clips

```auto
function fadeOut(){
this._alpha -= 5;
if (this._alpha < 10){
this.removeMovieClip();
}
}
this.onEnterFrame = function(){
i++;
var mc = this.attachMovie("theClip","theClip"+i,i);
mc._x = _xmouse;
mc._y = _ymouse;
mc.onEnterFrame = fadeOut;
}

```

You can do pretty much anything you want in that function.  
The next step would be attaching the clip at another position that the mouse position, making the clips react to each other…

mmhhh. Doesnt that make the CPU blow up?, looks like the loop could be repeated billions of of times…

</div>

because the clip’s enterFrame is fadeout, it will end up removing itself after a couple of frames and you wont have to worry about it clogging up the system - clips get removed at the same rate they are added so you get an equilibrium 🙂

who needs to keep duplicating movieclips when you can have a set amount with the ilusion of fading… try this:  
[AS]numMCs = 100; //the number of movie clips that will trail  
speed = 1.1; //the speed at which the movie clips will follow the mouse  
for (i=1; i\<=numMCs; ++i) { //starts a for loop  
MC = “MC”+i; //MC is a variable that stores the names of all the new movie clips  
//MC is updated every loop  
\_root.attachMovie(“MCID”, MC, i); //attaches a movie clip from the library with the linkage name “MCID”  
\_root[MC].\_alpha = (100/numMCs)\*(numMCs-i+1); //adjusts each MC’s alpha. if you’re going to use 100 MC’s the  
//just use 'MC.\_alpha = 100-(i+1). the original code spreads out  
//alpha throughout the MC no matter how many you have  
} //ends the for loop  
onEnterFrame = function () { //starts an onEnterFrame function  
for (i=1; i\<=numMCs; ++i) { //starts a for loop  
MC = “MC”+i; //stores the names of all the new movie clips  
if (i == 1) { //checks if i is equal to 1  
\_root[MC].\_x = \_xmouse; //if i = 1 then the loop is on the first loop and on the first MC  
\_root[MC].\_y = \_ymouse; //this means the first MC has to follow the mouse  
} else { //if the above if statement is not satisfied, then do the following actions  
MCb = “MC”+(i-1); //MCb stores the name of the MC that’s ahead of it  
\_root[MC].\_x -= (\_root[MC].\_x-\_root[MCb].\_x)/speed; //the current MC eases towards the MC that’s  
\_root[MC].\_y -= (\_root[MC].\_y-\_root[MCb].\_y)/speed; //ahead of it  
} //closes the if statement  
} //declares the end of the for loop  
}; //declares the end of the onEnterFrame function[/AS]
