button that randomizes location of objects,when clcked again del the old stuff & reputs stuff.help

[J_DAWG1]

Hello world I'm trying to make a program that when I click the randomize button it randomly puts objects in a given area and if you hit the button again it should delete the objects and put on a new randomized pattern of objects.

need help!!!!

as of the moment I only have a "else is unexpected" error but I'm afraid my idea night not work help please!!!!

that error means you have a mismatched curly bracket somewhere.

what shape is your "given area" and what objects do you want to position there?

[J_DAWG1]

My shape is a square and to make sure it's in the square I have the check boundry function and I'm trying to put objects (tree.grass1,grass2,grass3,grass4,grass5)

[J_DAWG1]

and thank you I found where I was missing the curly bracket

[kglad]

can the objects overlap?

[J_DAWG1]

Yes

[kglad · Accepted solution]

// define your rectangle and call positionItemsF whenever you want to randomize/re-randomize the items' positions.

var r:Rectangle = new Rectangle(100,200,300,300);

var itemA:Array = [tree,grass1,grass2,grass3,grass4,grass5];

positionItemsF();

function positionItemsF():void{

    for(var i:int=0;i<itemA.length;i++){

         // if your items have top left reg point

        itemA.x = randomF(r.left,r.left+r.width-itemA.width);

        itemA.y = randomF(r.top,r.top+r.height-itemA.height);

    }

}

function randomF(n1:int,n2:int):int{

    if(n1<n2){

        return n1+Math.floor((n2-n1+1)*Math.random());

    } else {

        return n2+Math.floor((n1-n2)*Math.random());

    }
