Function in Sprite does not run to display - actionscript-3

Question

Function X1 simply does not run- no trace result and programme so basic.
Board.as is called- I checked.
Simple sprite display not working.
Main.as
package
{
import flash.display.Bitmap;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.*;
import flash.text.TextField;
import flash.ui.Keyboard;
import Start;
import Board;
/**

*/
public class Main extends Sprite
{
public function Main():void
{
if (stage) init();
else addEventListener(Event.ADDED_TO_STAGE, init);
}
private function init():void
{
removeEventListener(Event.ADDED_TO_STAGE, init);
var Board1:Sprite = new Board();
stage.addChild(Board1);
Board1.visible = true;
var Start1:Sprite = new Start();
Start1.x = 32;
Start1.y = 32;
addChild (Start1);
stage.addEventListener(KeyboardEvent.KEY_DOWN, myKeyDown);
function myKeyDown(e:KeyboardEvent):void{
if (e.keyCode ==Keyboard.SPACE)
{
removeChild(Start1);
Start1 = null;
}
}
}
Board.as
package
{
import flash.display.Bitmap;
import flash.display.Graphics;
import flash.display.Sprite;
/**

*/
public class Board extends Sprite
{
[Embed(source="../lib/Board.jpg")]
private var BoardClass :Class
public function X1():void
{
var boardclass:Bitmap = new BoardClass () as Bitmap;
trace("Project is running fine!");
this.addChild(boardclass);
}
}
}

Answer 1

You are not calling the function X1(). Change the code part in your Main.as class where you create the Board to this:
var Board1:Sprite = new Board();
Board1.X1();
stage.addChild(Board1);
A few more tips for your code:
1) You don't need Board1.visible = true;, it's visible by default
2) Change the name of Board1 to board1 or just board. It's a standard to call classes with first capital letter.
EDIT:
If you want X1() to be run as you create the object, call this function in the constructor of Board.as. Constructor is a function that is run when you create an object. For Board.as it would be like this:
public function Board():void
{
X1(); // this function will be called when you create a new Board object
}
