Help/clean up

1

OK, don’t be harsh as this is my first ever code in as3 --and I did it from scratch (I did look up stuff to find out about the ‘event handlers’ and ‘beginfill stuff’).

How would I go about cleaning it up? Making it more dynamic? Easier to edit?

stop()
toolbar.shapeType.text='Rectangle'
var num:int=0
var names:Array=['Rectangle', 'Ellipse', 'Cirlce']
var dragging:Boolean=false
var setVar:Boolean=false

var temp:MovieClip=new MovieClip()
var level:MovieClip=new MovieClip()
var colorTransform:ColorTransform = level.transform.colorTransform;
stage.addChild(level)

var locationY:int
var location2X:int
var location2Y:int

stage.addEventListener(MouseEvent.MOUSE_DOWN, mousedown); 


function mousedown(evt:MouseEvent):void

locationX=evt.target.mouseX
locationY=evt.target.mouseY
}

stage.addEventListener(MouseEvent.MOUSE_UP, mouseup); 

function mouseup(evt:MouseEvent):void 
{
    if (dragging==true)
    {
        dragging=false
        level.graphics.beginFill(0x00FFFF);
        switch(num){ 
            case 0:
                level.graphics.drawRect(locationX, locationY, location2X, location2Y)
                break
            
            case 1:
                level.graphics.drawEllipse(locationX, locationY, location2X, location2Y)

/* Mouse Click Event
Clicking on the specified symbol instance executes a function in which you can add your own custom code.

Instructions:
1. Add your custom code on a new line after the line that says "// Start your custom code" below.
The code will execute when the symbol instance is clicked.
*/

button_1.addEventListener(MouseEvent.CLICK, clickPlay);

function clickPlay(event:MouseEvent):void
{
    // Start your custom code
    // This example code displays the words "Mouse clicked" in the Output panel.
    play();
    // End your custom code
}

Thanks, in advance! :thumb2:
