There has to be a better way to do this, but I’ve been banging my head against the wall for four days now.

I have a little game going where a movieclip (star) bounces off of some obstacles (cloud). The clouds are generated using a loop. When the star hits a cloud, the cloudMC advances to the next frame and then removes itself.

The problem is I have to declare a hittest for each cloud.

Anyone have any idea how I can use the array variable to detect which cloud is being hit?

Thanks in advance for any suggestions

See code below:

//CLOUD MAKER  
floatcloud = function () {

```
clouds = 20;
// quantity 
for (var i=0; i&lt;clouds; i++) {
    q = attachMovie("cloudMC", "cloud"+i, i);
    q._x = random(600);
    q._y = random(900);
    q.drop = .75;
    q.wind = -0.5+Math.random()*(0.4*3);
    q.onEnterFrame = cloudmover;
    
}

```

};  
floatcloud();

//STAR PHYSICS  
\_root.attachMovie(“star”, “starMC”, 10000,{\_x:300,\_y:100});  
power = 0.25;  
yspeed = 0.0;  
xspeed = 0.0;  
wind = 0.00;  
gravity = 0.10;  
upconstant = 0.25;  
friction = .99;

starMC.onEnterFrame = function() {

//STAR START MOTION  
xspeed = (xspeed+wind)\*friction;  
yspeed = yspeed+gravity;  
if (xspeed\>15) {  
xspeed = 15;  
}  
if (xspeed\<-15) {  
xspeed = -15;  
}  
if (yspeed\>15) {  
yspeed = 15;  
}  
if (yspeed\<-15) {  
yspeed = -15;  
}

```
this._y += yspeed;
this._x += xspeed;

```

//STAR CONTROLS  
if (Key.isDown(Key.LEFT)) {  
xspeed = xspeed-power;  
}  
if (Key.isDown(Key.RIGHT)) {  
xspeed = xspeed+power;  
}  
if (Key.isDown(Key.UP)) {  
yspeed = yspeed-power_upconstant;  
}  
if (Key.isDown(Key.DOWN)) {  
yspeed = yspeed+power_upconstant;  
}

//cloud hit
