Above and beyond that, there are a few bugs which need to be fixed.
1. Case Sensitivity - DrawIcons has properties xValue and yValue, but yet
the constructor references Xvalue and YValue
2. Scope issues. - DrawIcons has no concept of MyCanves (referenced in
createSquare()). By adding an argument to createSquare, in which you pass
the canvas can solve this.
3. DrawIcons isnt a subclass of MovieClip, UIObject or any other class
which has a method called getNextHighestDepth(). We'll need to change that
reference to the canvas passed into createSquare.
The modified codebase, which works fine, looks like this:
DrawIcons.as
=====
//Class definition
class DrawIcons{
var xValue:Number;
var yValue:Number;
//Contractor
function DrawIcons(cordiX:Number,cordiY:Number){
this.xValue=cordiX;
this.yValue=cordiY;
}
//Drawing square
function createSquare(mc) {
var square_mc:MovieClip;
square_mc =
mc.createEmptyMovieClip("square_mc",mc.getNextHighestDepth());
square_mc.lineStyle(1, 0x000000, 100);
square_mc.beginFill(0xFF0000, 100);
square_mc.moveTo(0, 0);
square_mc.lineTo(50, 0);
square_mc.lineTo(50, 50);
square_mc.lineTo(0, 50);
square_mc.lineTo(0, 0);
square_mc.endFill();
square_mc._x = this.Xvalue;
square_mc._y = this.Yvalue;
}
}
Square.mxml
=====
<mx:Application width="800" height="600"
xmlns:mx="http://www.macromedia.com/2003/mxml";>
<mx:Script>
<![CDATA[
function callDrawIcons(){
var Square1:DrawIcons = new DrawIcons(100, 200);
var Square2:DrawIcons = new DrawIcons(100, 300);
Square1.createSquare(MyCanves);
Square2.createSquare(MyCanves);
}
]]>
</mx:Script>
<mx:Canvas id="MyCanves" width="600" height="400"
initialize="callDrawIcons()"/>
</mx:Application>
