[Help][AS2-AS3] Fast Track
Previously I coded in AS2 now I'm trying to make the switch to AS3. I checked out the migration doc but am still stumped on this one,
file: graphics_c.as
AS3:
Code:
package{
import flash.display.DisplayObject;
import flash.display.Graphics;
import flash.display.Shape;
import flash.display.Sprite;
public class graphics_c extends Sprite {
private var color:uint = 0x000000;
private var thick:uint = 1;
private var fill:uint = 0xFEC878;
public function graphics_c(){}
public function fillCircle(x:int,y:int,r:uint):void {
var child:Shape = new Shape();
child.graphics.beginFill(fill);
child.graphics.lineStyle(thick, color);
child.graphics.drawCircle(x, y, r);
child.graphics.endFill();
addChild(child);
}
public function polygon(arr:Array):void {
var child:Shape = new Shape();
child.graphics.lineStyle(thick, color);
child.graphics.moveTo(arr[0], arr[1]);
child.graphics.beginFill(fill);
for (var i = 0; i<arr.length; i += 2) {
if (i == 0) {
child.moveTo(arr[i], arr[i+1]);
} else {
child.lineTo(arr[i], arr[i+1]);
if (i == 6 || i == 2) {
child.lineStyle(thick, color, 0);
} else {
child.lineStyle(thick, color);
}
}
}
child.graphics.endFill();
addChild(child);
}
}
}
'uint' stands for unsigned integer and they use it in the docs. This is the error I'm getting for the polygon function:
Code:
ReferenceError: Error #1069: Property moveTo not found on flash.display.Shape and there is no default value.

see working code in AS2 below...
file: graphics_c.as
AS2:
Code:
class graphics_c extends MovieClip {
var mc;
var color:String;
var thick:Number;
var fill:String;
public function graphics_c(depth:Number) {
mc = _root.createEmptyMovieClip("test1", depth);
color = "0x000000";
thick = 1;
fill = "0xFEC878";
}
public function fillCircle(r:Number, x:Number, y:Number) {
var styleMaker:Number = 22.5;
mc.moveTo(x+r, y);
mc.lineStyle(thick, color);
mc.beginFill(fill);
var style:Number = Math.tan(styleMaker*Math.PI/180);
for (var angle:Number = 45; angle<=360; angle += 45) {
var endX:Number = r*Math.cos(angle*Math.PI/180);
var endY:Number = r*Math.sin(angle*Math.PI/180);
var cX:Number = endX+r*style*Math.cos((angle-90)*Math.PI/180);
var cY:Number = endY+r*style*Math.sin((angle-90)*Math.PI/180);
mc.curveTo(cX+x, cY+y, endX+x, endY+y);
}
mc.endFill();
}
public function polygon(mc, arr:Array) {
var len = arguments.length;
mc.lineStyle(thick, color);
mc.beginFill(fill);
for (var i = 0; i<arr.length; i += 2) {
if (i == 0) {
mc.moveTo(arr[i], arr[i+1]);
} else {
mc.lineTo(arr[i], arr[i+1]);
if (i == 6 || i == 2) {
mc.lineStyle(thick, color, 0);
} else {
mc.lineStyle(thick, color);
}
}
}
mc.endFill();
return mc;
}
}
file: graphics.fla
script in actions frame
Code:
var gfx:graphics_c = new graphics_c();
var arr:Array = new Array(0,0,0,50,50,50,50,0);
gfx.fillCircle(0,0,10);
gfx.polygon(arr);
Anyone with solutions or their own AS2-AS3 migration trouble please post below... that way we'll get a collection of known issues.
Thanks,
