Hello,

I'm attempting to make a very simple drawing programme. There will be maybe 4/5 buttons. Three of them when you click on the change the color of the line the user draws. the other two will change the line thickness. I've tried setting up a variable to set to how thick the line should be depending on the button the user has pressed.

But it has no effect - i'm guessing that's because the variable only exists within the confines of the function that I have it in. So how do I allow the variable to exist globally, or am I going the wrong way about this.

Below is the code that has been a class (i'm using as3)....

Code:

 package{
    import flash.display.*;
    import flash.events.MouseEvent;
    
    public class Artist extends Sprite{
    //Are we drawing or not?
    private var drawing:Boolean;
     
    
    public function Artist(){
        
        var color
        var colorNo;
        var colorNo1
        var width1 = 15
        blueButton.addEventListener(MouseEvent.CLICK, blueF)
        blackButton.addEventListener(MouseEvent.CLICK, blackF)
        redButton.addEventListener(MouseEvent.CLICK, redF)
        
        wideButton.addEventListener(MouseEvent.CLICK, wide)
        
        
        function wide()
        {
            width1 = 15
        
        }
        
        
        function blueF()
        {
            colorNo1 = 0x0000FF
            colorNo = 1
            if (colorNo == 1)
        {color = 0x0000FF
        graphic_mc.graphics.lineStyle(width1,color);
        }
        
        
        
            graphic_mc.graphics.lineStyle(width1,color);
            trace ("yes")
            trace (colorNo+"colorNo")
        }
        
        
        function blackF()
        {
            colorNo = 2
            
        if (colorNo == 2)
        {color = 0x000000
        graphic_mc.graphics.lineStyle(width1,color);
        }
        
        
            graphic_mc.graphics.lineStyle(width1,color);
            trace ("yes")
            trace (colorNo+"colorNo")
        }
        
        
        function redF()
        {
            colorNo = 3
            
        if (colorNo == 3)
        {color = 0xFF0000
        graphic_mc.graphics.lineStyle(width1,color);
        }
        
        
            graphic_mc.graphics.lineStyle(width1,color);
            trace ("yes")
            trace (colorNo+"colorNo")
        }
        
        
        graphic_mc.graphics.lineStyle(width1,color);
        drawing = false;//to start with
        stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
        stage.addEventListener(MouseEvent.MOUSE_MOVE, draw);
        stage.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
    }
    
    public function startDrawing(event:MouseEvent):void{
        //move to the correct starting position for drawing
        graphic_mc.graphics.moveTo( mouseX, mouseY);
        drawing = true;
    }
    
        public function draw(event:MouseEvent){
        if(drawing){
            graphic_mc.graphics.lineTo(mouseX,mouseY);
        }
    }
    
        public function stopDrawing(event:MouseEvent){
        drawing = false;
    }
}
