Simple click and hit flash game - actionscript-3

Question

I am trying to create a simple game like whack a mole, what I want is for instead of mole make rectangle appear and disappear quickly on screen and the player has to click it more rectangles he click more his score increases.
I think it's a fairly simple game but my problem is:
How do I make the rectangles appear and disappear on screen at random position also at increasing speeds as the timer is decreasing? i.e speed of rectangles appearing and disappearing increases as the time reduces, there is a countdown time as player gets to play for 30 sec.
import flash.utils.Timer;
import flash.events.TimerEvent;
import flash.events.Event;
var inc:Number = 1;
var gogo:Timer = new Timer(inc*1000);
var val:Number = 30;
var counter = val;
var time2:Timer = new Timer(1000+speed);
var speed:Number = 50;
timee.text = counter;
box.addEventListener(MouseEvent.CLICK, st);
function st(event:MouseEvent):void
{
gogo.start();
time2.start();
}
gogo.addEventListener(TimerEvent.TIMER, res);
function res(ev:TimerEvent):void
{
if(counter == 0){
gogo.stop();
}else{
val = val - inc;
counter = val;
timee.text = counter;
}
}
stage.addEventListener(Event.ENTER_FRAME, yea);
function yea(e:Event):void{
speed += 50;
}

Answer 1

It seems to me that you need a math.random() method.
explained here
I'd personally have every successful 'hit' lower a "blinkSpeed" variable by either a set fraction of a second or a percentage and use that variable as my random input "max" number. That way it would decrease the time it could be available for automatically as they play.

Hello
Well, that wouldn't be much hard! Here's a clue.
Step1 : Create a new movieclip.
Step2 : Right click on your movie clip in the library. Click properties. Check the "Export for ActionScript" checkbox. Name the class MyEnemy (for example).
Step3 : Go to the frame and pull the Actions window.
Now put this code in it :
var mc:MyEnemy= new MyEnemy() // creates a instance of the movieclip.
addChild(mc); // adds the movie clip to the stage.
Step 4 : Now that we have added a new movieclip to the stage. To add it at a random x location in the stage, you need to make use of mc's x and y fields and the Math.random() function.
Example of Math.random() :
var randomThing:Number = Math.random() * 100 // returns a number between n, where 0 <= n < 100
Now, for example, we need both x and y values relative to the stage you must multiply Math.random() with the stage's width instead. As follows :
var randomX:Number = Math.random() * stage.stageWidth // returns a number between n, where 0 <= n < stage.stageWidth
var randomY:Number = Math.random() * stage.stageWidth // returns a number between n, where 0 <= n < stage.stageWidth
And! The magic final code would be :
mc.x = randomX;
mc.y = randomY;
Edit 1 : To add multiple "mc" movieclips to stage, we would use loops, do the follow :
stage.addEventListener(Event.ENTER_FRAME, doSimple);
function doSimple (ev:Event) {
var mc:MyEnemy = new MyEnemy();
var randomX:Number = Math.random() * stage.stageWidth // returns a number between n, where 0 <= n < stage.stageWidth
var randomY:Number = Math.random() * stage.stageWidth // returns a number between n, where 0 <= n < stage.stageWidth
for (var i:Number=1; i<=10;i++){ //i is a number, you can discard the 'i<=10' if you want an infinite loop.
addChild(mc);
}
mc.x = randomX;
mc.y = randomY;
trace("yes");
}
Conclusion : I look forward for your feedback!
