Hi, I can't get some getters and setters to work between these two classes so I can't communicate between them. the first class contains the variables for a spaceship to move and the second class is a scrolling class that uses the variables with parallax scrolling for the background. Here is part of the first class here:

public function update():void
{
if (_gameModel.gameMode != "play") return;
temporaryX = _xPos;
temporaryY = _yPos;

vx += acceleration_X;
vy += acceleration_Y;


_xPos += vx + gravity_Vx;
_yPos += vy + gravity_Vy;

previousX = temporaryX;
previousY = temporaryY;

_scroll.update();


_collision.playerVsGround(this, foreground1);

}
public function render():void
{
//Draw the object

//Position object
_player.x = _xPos;
_player.y = _yPos;


}



public function get vx():Number
{
return _xPos - previousX;
}
public function set vx(value:Number):void
{
previousX = _xPos - value;
}

//vy
public function get vy():Number
{
return _yPos - previousY;
}
public function set vy(value:Number):void
{
previousY = _yPos - value;
}

//xPos
public function get xPos():Number
{
return _xPos;
}
public function set xPos(value:Number):void
{
_xPos = value;

}

//yPos
public function get yPos():Number
{
return _yPos;
}
public function set yPos(value:Number):void
{
_yPos = value;

}

//setX
public function set setX(value:Number):void
{
previousX = value - vx;
_xPos = value;
}

//setY
public function set setY(value:Number):void
{
previousY = value - vy;
_yPos = value;
}






...and the second class....

public function initializeScroll():void
{
//Initialize the scrolling variables
_rightInnerBoundary
= (_stage.stageWidth * 0.5) + (_stage.stageWidth * 0.25);
_leftInnerBoundary
= (_stage.stageWidth * 0.5) - (_stage.stageWidth * 0.25);
_topInnerBoundary
= (_stage.stageHeight * 0.5) - (_stage.stageHeight * 0.25);
_bottomInnerBoundary
= (_stage.stageHeight * 0.5) - (_stage.stageHeight * 0.25);

}
public function update():void
{
var lunarMain:LanderMain = new LanderMain();
var background3:Bitmap = _gameModel.bg2;
var background2:Bitmap = _gameModel.bg1;
var background:Bitmap = _gameModel.foreground1;

//Capture the current background x and y positions before
//they're changed by scrolling
var temporaryX:Number = background.x;
var temporaryY:Number = background.y;

var playerWidth:int = 63;
var playerHeight:int = 53;




var pHW:Number = playerWidth*.5;
var pHH:Number = playerHeight*.5;

//Stop player at inner boundary edges
if (lunarMain.xPos <= _leftInnerBoundary)
{
lunarMain.setX = _leftInnerBoundary;
_rightInnerBoundary
= (_stage.stageWidth * 0.5)
+ (_stage.stageWidth * 0.25);
background.x -= lunarMain.vx;
background2.x -= lunarMain.vx *.4;
background3.x -= (lunarMain.vx *.4)*.4;
}
else if (lunarMain.xPos >= _rightInnerBoundary)
{
lunarMain.setX = _rightInnerBoundary;
_leftInnerBoundary
= (_stage.stageWidth * 0.5)
- (_stage.stageWidth * 0.25);
background.x -= lunarMain.vx;
background2.x -= lunarMain.vx *.4;
background3.x -= (lunarMain.vx *.4)*.4;
}
if (lunarMain.yPos <= _topInnerBoundary)
{
lunarMain.setY = _topInnerBoundary;
_bottomInnerBoundary
= (_stage.stageHeight * 0.5)
- (_stage.stageHeight * 0.25);
background.y -= lunarMain.vy;
background2.y -= lunarMain.vy *.4;
background3.y -= (lunarMain.vy *.4)*.4;
}

else if (lunarMain.yPos >= _bottomInnerBoundary)
{
lunarMain.setY = _bottomInnerBoundary;
_topInnerBoundary
= (_stage.stageHeight * 0.5)
- (_stage.stageHeight * 0.25);
background.y -= lunarMain.vy;
background2.y -= lunarMain.vy *.4;
background3.y -= (lunarMain.vy *.4)*.4;
}
trace(lunarMain, background.x, background.y, lunarMain.vx, lunarMain.vy, lunarMain.xPos, lunarMain.yPos);

//Stop background at _stage edges
if (background.x + background.width < _stage.stageWidth)
{
background.x = _stage.stageWidth - background.width;
_rightInnerBoundary = _stage.stageWidth;
if(lunarMain.xPos >= _rightInnerBoundary){
lunarMain.vx = 0;
}
}
else if (background.x > 0)
{
background.x = 0;
_leftInnerBoundary = 0;
if(lunarMain.x <= _leftInnerBoundary){
lunarMain.vx = 0;
}


}
if (background.y > 216)
{
background.y = 216;
_topInnerBoundary = 0;
if(lunarMain.yPos <= _topInnerBoundary){
lunarMain.vy = 0;
}

}
else if (background.y + background.height < _stage.stageHeight)
{
background.y = _stage.stageHeight - background.height;
_bottomInnerBoundary = _stage.stageHeight;
if(lunarMain.yPos >= _bottomInnerBoundary){
lunarMain.vy = 0;
}
}
if (lunarMain.xPos-pHW <= 0)
{
lunarMain.xPos = pHW;
}
if (lunarMain.xPos+pHW >= _stage.stageWidth)
{
lunarMain.xPos = _stage.stageWidth - pHW;
}

if (lunarMain.yPos+pHH >= _stage.stageHeight)
{
lunarMain.yPos = _stage.stageHeight - pHH;
}





scroll_Vx = background.x - temporaryX;
scroll_Vy = background.y - temporaryY;

_gameModel.scroll_Vx = scroll_Vx;
_gameModel.scroll_Vy = scroll_Vy;




}


if anyone has a clue why I can't communicate between the classes let me know. I know that is the problem because I traced the second class with this trace statement...trace(lunarMain, background.x, background.y, lunarMain.vx, lunarMain.vy, lunarMain.xPos, lunarMain.yPos); and none of the values are changing, but they change in the LunarMain class. If someone can see or knows the problem let me know.

Many Thanks,
