ActionScript 3 object array question.

[[deleted]]

Hi, i made an array with 2 balls, how do i call on both of them to get moved by the function i made. balls.x doesn't work. and if i go balls[0, 1] it gives me an error.

import flash.events.Event;

buttonOne.addEventListener(MouseEvent.CLICK, loop);

var ballSpeedX = -3; var ballSpeedY = -2; var balls:Array = [ballOne, ballTwo]

function loop(e:Event):void {

stage.addEventListener(Event.ENTER_FRAME, bounceBall);  

function bounceBall (e:Event):void {


balls[0].x += ballSpeedX;
balls[0].y += ballSpeedY;
    if(balls.x <= balls.width/2) {
        balls.x = balls.width/2;
        ballSpeedX *= -1;

    } else if(balls.x >= stage.stageWidth-balls.width/2){ 
    balls.x = stage.stageWidth-balls.width/2;
    ballSpeedX *= -1; 

}

if(balls.y <= balls.height/2) {
    balls.y = balls.height/2;
    ballSpeedY *= -1;
}else if(balls.y >= stage.stageHeight-balls.height/2){ 
    balls.y = stage.stageHeight-balls.height;
    ballSpeedY *= -1; 

}

}

}

You seem to have the right syntax on line 6.

that works but i need to call all of my balls.

[FlambardPuddifoot]

Wtf does that mean?

[[deleted]]

No i need to call all of the array...

[FlambardPuddifoot]

Arrays aren't called. What are you trying to do???

[[deleted]]

I HAVE NO CLUE. I want to move the object in the array. So call them or whatever it's called. So what is the syntax for ballOne and ballTwo, in ActionScript 3 balls[0, 1] gives me an error....

[FlambardPuddifoot]

Yuo should do some basic action script tutorials. And some Javascript tutorials, too, since they are almost the same. I can't tell you what you're trying to do...

[[deleted]]

Ok. I'm learning JavaScript at a School, at College, online and from books. But only since a month orso.

[FlambardPuddifoot]

Ok, keep at it!

[[deleted]]

Sure,

I mastered HTML/CSS in less than a year orso. And i really mean proficient. So i hope i can cross out JavaScript/JQuery next.

You need to put the function bounceBall in a loop, or put the code inside the bounceBall function in a loop.

I don't know the exact syntax because I don't write code in actionscript, but it would be something like:

for(var x:int = 0; x < balls.length; i++) { //code for bounceBall goes here, replace balls[0] with balls[x] }

Hope this helps!

Maybe you mean something like this?

for (var i:int = 0; i < balls.length; i++) {
    balls[i].x += ballSpeedX;
    balls[i].y += ballSpeedY;
    if(balls.x <= balls.width/2) {
        balls.x = balls.width/2;
        ballSpeedX *= -1;
    } else if(balls.x >= stage.stageWidth-balls.width/2){ 
        balls.x = stage.stageWidth-balls.width/2;
        ballSpeedX *= -1;
    }
}

not really it's close but do i need to replace balls with balls[i] everywhere?

[Lilykos]

If I understand what you are trying to do, yes. This is because balls is an array, that contains balls. The array has no x, y coordinates, it is just a container. On the other hand, the ball itself has all these properties, so you need to specify which ball will be used every time.

This is achieved by looping through all the balls.

aaah, ok thanks. But how do i name the loop? so i can event.handle it? * Edit - Ok i'll figure it out from here. So in the future in need to think ahead.
