How to clean this switch code

programming flash
1

Right, I have this code and it works perfectly fine but I can imagine it could be a lot compacter. The thing my code does is adds 12 movieclips on the stage with a for loop and when you click on one of the movieclip it traces which mc you clicked and gives two variables numbers. The numbers depend on the the clicked mc, the numbers are not related to each other . I made a switch function but maybe there is a cleaner solution. Does any of you have an idea?


    public function makeBreadCrumbs() {
        
    for (var i:Number = 0;i <12; i++){
    spore = new myFooter()
    addChild(spore)
    spore.x = 50+spore.width * i
    spore.y = 200
    spore.Step_text.text = "Step " + (i +1)
    spore.Step_text.mouseEnabled = false
    spore.name = "Step" + i 
    spore.buttonMode = true
    crumbHeight = spore.height
    
    crumbsArray.push (spore);
    
    spore.addEventListener( MouseEvent.CLICK, onMenuItemClick );
    spore.addEventListener( MouseEvent.MOUSE_OVER, crumbsMouseOver);
    spore.addEventListener( MouseEvent.MOUSE_OUT, crumbsMouseOut);
    
    }
        }
        
    public function onMenuItemClick(evt:MouseEvent):void{
        trace ("clicked item " + evt.target.name)
        evt.target.addChild (pointer)
        pointer.mouseEnabled = false
        pointer.y = -crumbHeight/2

        switch (evt.target.name){
        case "Step0":
        xPosition = 10
        yPosition = 10
        break;
        case "Step1":
        xPosition = 35
        yPosition = 20
        break;
        case "Step2":
        xPosition = 302
        yPosition = 30
        break;
        case "Step3":
        xPosition = 500
        yPosition = 40
        break;
        case "Step4":
        xPosition = 50
        yPosition = 50
        break;
        case "Step5":
        xPosition = 150
        yPosition = 60
        break;
        case "Step6":
        xPosition = 70
        yPosition = 75
        break;
        case "Step7":
        xPosition = 220
        yPosition = 130
        break;
        case "Step8":
        xPosition = 90
        yPosition = 90
        break;
        case "Step9":
        xPosition = 103
        yPosition = 100
        break;
        case "Step10":
        xPosition = 15
        yPosition = 110
        break;
        case "Step11":
        xPosition = -200
        yPosition = 120
        break;
        }
changeMountainPosition()
    }
