actionscript 3 remove or stop for loop

this is a part of my code:

private var sun:Sun;
private var aantalSun:int = 5;
private var counter:int;

for (counter = 0; counter < aantalSun; counter++)
{
    sun = new Sun();
    addChild(sun);
}

when the whole code is running, there is a button called 'menu' on the stage. when i click that button, i want to go back to my main menu, but there are still 5 sun on my stage. how can i remove the 5 sun (like, stop the loop?) when i click the menu button? i already tried removeChild(sun);, but then only one sun goes away.

Here's what you need (rhe function at the bottom) as well as the small changes to your original posted code.

private var sun:Sun;
private var aantalSun:int = 5;
private var counter:int;

private var sunContainer:Sprite = new Sprite();
addChild(sunContainer);

for (counter = 0; counter < aantalSun; counter++)
{
    sun = new Sun();
    sunContainer.addChild(sun);
}




//function for clearing all suns
function clearSuns(e:Event = null):void {
    var i:int = sunContainer.numChildren;
    while(i--){
        sunContainer.removeChildAt(i);
    }
}

Store the "suns" in an array and loop trough this to remove all suns:

private var sun:Sun;   
private var aantalSun:int = 5;   
private var counter:int;
private var sunArray:Array = new Array();

for (counter = 0; counter < aantalSun; counter++) { 
    sun = new Sun();
    sunArray.push(sun);
    addChild(sun); 
} 

function RemoveSuns() {
    for (var i:int = 0; i < sunArray.length; i++) { 
        removeChild(sunArray[i]);
    } 
}

OR you remove ALL:

function RemoveAll() {
    for(var i:int = 0; i < this.numChildren; i++) {
        this.removeChildAt(i);
    }
}

Actually looping of 5 iterations will done so fast that you cant exit from the loop when a button is pressed.

What I understood is you want to remove the added 5 suns when the button is pressed.

What I would suggest is create parent of your 5 suns and add it to that and remove your parent so that all 5 childs will be removed. No need to maintain 5 childs references and you have to maintain only one parent reference.

Stop the loop and exit it with the break command; So if you have a condition that you can check like the var menuClicked you can make liek this:

for (counter = 0; counter < aantalSun; counter++)
{
 if(menuClicked) break;
 sun = new Sun();
 addChild(sun);
}
