Forums → Programming Forum → I'm making a tutorial...

Recently, my 30 day trial of Adobe Flash CS5 ended.

All I've got to show for it is a (very) simple game.

In it, a ball bounces around and you have to click on it. When you do, you get 1 point and the ball teleports to a new location.

A lot of my 30 days was spent hunting books and internet resources to make it. I think that if I made a tutorial for the ball bouncing thing, then other people on the trial wouldn't have to hunt everywhere.

BUT... I'm not sure if the code I'm using is the best way to do it. So I'm asking the awesome people at AG to look at my code and see if it can be improved, so that I don't end up teaching bad practices in the tutorial.

The ball is called button. The text box containing the score is called scoreBox.

var score:Number = 0;
var hdirect:Number = Math.random()*10;
var vdirect:Number = 10-hdirect;
trace("Horizontal direction: " + hdirect);
trace("Vertical direction: " + vdirect);

button.addEventListener(MouseEvent.CLICK,addone);

function addone(e:MouseEvent)
{
score += 1;
trace(score);
scoreBox.text = score.toString();
button.x = Math.random()*520;
button.y = Math.random()*370;
hdirect = Math.random()*10;
vdirect = Math.random()*10;
var random1 = Math.random();
var random2 = Math.random();
}

button.addEventListener(Event.ENTER_FRAME,movement);

function movement(e:Event)
{
if (button.x > 520)
{
trace("hit!"
hdirect -= hdirect*2;
}
if (button.x < 0)
{
hdirect -= hdirect*2;
trace("hit!&quot;
}
if (button.y > 370)
{
trace("hit!&quot
vdirect -= vdirect*2;
}
if (button.y < 0)
{
trace("hit!&quot
vdirect -= vdirect*2;
}
button.x += hdirect;
button.y += vdirect;

}
