Adding a bitmap graphic to a movieclip

Hi, I’m new to as3 and programming and I’m trying to add a bitmap to a movie clip in code. However, I’m having trouble getting the bitmap location to go where I want it because it’s inside the movieclip and it just shows up at 0,0 of the movieclip instead of the coordinates I want it to be: Here’s some of code so you can see what I mean:

imageBitmapData3 = new Lander(63, 53);

		_player = new Bitmap(imageBitmapData3);
		
		_gameLevel.addChild(_player);
		_player.x = 145;
		_player.y = 90;

-Instead of showing up at 145, 90 It just shows up at the movieclip, _gamelevel, 0,0.

does anyone know how I could get it to do what I want it to do? I want to add it inside the mc because I need everything to move with the _gameLevel background when I move it.

Thanks
