    Making multiple items invisible

    Hi guys sorry if this is a simple question, but I've been trying to do this all day! So far I've been lucky and managed to find examples of everything else I've tried to do.

    Im making a game where you can modify a car, one of the options is to add different sets of wheels. I have 30 different wheels and I want to hide all the wheels apart from the ones the user has selected. I know I could do it like this:

    fivedoor_wheels.wheel1_btn.addEventListener(MouseE vent.CLICK, wheel1);

    function wheel1(event:MouseEvent):void {
    wheel1a.visible=true;
    wheel2a.visible=false;
    wheel3a.visible=false;
    wheel4a.visible=false;
    wheel5a.visible=false;
    wheel6a.visible=false;

    etc etc....

    But there must be a simpler way, as it will take ages to do this for all 30 wheels. Can anyone shed any light on this or point me in the right direction please? I've been looking at else and if statements but cant seem to come up with anything that works.

    Thanks Steve

    first you need to know Array
    It's a way to save a huge amount of similar of same thing,and handle them easily.

    step1
    var i:int=0
    var numArray:Array=new Array(0,0,0,0,0)
    numArray[1]+=1
    numArray[2]+=2
    numArray[3]+=3
    trace(numArray[0])
    trace(numArray[1])
    trace(numArray[2])
    trace(numArray[3])


    step2
    var i:int=0
    var numArray:Array=new Array(0,0,0,0,0)

    for(i=0;i<5;i++){
    numArray[i]+=a
    trace(numArray[i])
    }


    and before step3,you should know one more thing about Array


    var numArray:Array=new Array(0,0,0,0)

    equals

    var numArray:Array=[]
    numArray.push(0,0,0,0)

    equals

    var numArray:Array=[]
    numArray[0]=0
    numArray[1]=0
    numArray[2]=0
    numArray[3]=0



    wheelArray.length in step3 depends on how many things you push in the array

    step3
    var i:int=0
    var wheelArray:Array=[]

    wheelArray.push(wheel1a,wheel2a,wheel3a,wheel4a)

    for(i=1;i<wheelArray.length;i++){
    wheelArray[i].visible=false
    trace(i+':'wheelArray[i].visible)
    }




    and step4,which I don't suggest you to do at the moment,once you are familar with array,you can try this
    forEach

    step4
    var i:int=0
    var wheelArray:Array=[]

    wheelArray.push(wheel1a,wheel2a,wheel3a,wheel4a)

    wheelArray.forEach(afunction)
    function afunction(a,aa,arr){
    if(aa==0){
    trace(aa+':'a[aa].visible)
    return
    }
    a.visible=false
    trace(aa+':'a[aa].visible)
    return
    }
