Camera using glOrtho

[WillSmith190]

I made a very simple 2D game, and I had the camera working and everything. But then I found out that for 2D games, I should be using glOrtho (I was using gluPerspective). So I swapped over, and everything works but the camera.
I used this camera code, but modified it a bit for a 2D game: http://www.lloydgoodall.com/tutorials/first-person-camera-control-with-lwjgl/

My lookThrough() function looks like this:

public void lookThrough()
{
        GL11.glTranslatef(position.x, position.y, 0);
        //System.out.println(position.x + " : " + position.y); //debugging
}

And that worked with gluPerspective but it doesn't work with glOrtho. I initialize OpenGL like this:

GL11.glEnable(GL11.GL_TEXTURE_2D);
GL11.glDisable(GL11.GL_DEPTH_TEST);		
GL11.glMatrixMode(GL11.GL_PROJECTION);
GL11.glLoadIdentity();
GL11.glOrtho(0, width, height, 0, -1, 1);

and my render code is like this:

GL11.glLoadIdentity();
handleKeyboard();			
camera.lookThrough();
renderManager.RenderAll();
Display.update();

renderManager.RenderAll(); is this:

public void RenderAll()
{
	GL11.glClear(GL11.GL_COLOR_BUFFER_BIT | GL11.GL_DEPTH_BUFFER_BIT);
	GL11.glMatrixMode(GL11.GL_MODELVIEW);
	GL11.glLoadIdentity();
		
	RenderTerrain();
}

RenderTerrain just renders all my terrain tiles. Their render functions are this:

public void render()
{
	{
		GL11.glPushMatrix();
                {
        	        GL11.glTranslatef(pos.x, pos.y, 0);	
		        GL11.glBegin(GL11.GL_QUADS);      
		        {        			    
		                 GL11.glTexCoord2f(uvCoords[0][0], uvCoords[0][1]); GL11.glVertex3f(-size, size, 0.0f);       	        
		                 GL11.glTexCoord2f(uvCoords[1][0], uvCoords[1][1]); GL11.glVertex3f( size, size, 0.0f);        	
		                 GL11.glTexCoord2f(uvCoords[2][0], uvCoords[2][1]); GL11.glVertex3f( size,-size, 0.0f);        	
		                 GL11.glTexCoord2f(uvCoords[3][0], uvCoords[3][1]); GL11.glVertex3f(-size,-size, 0.0f);  
		        }
		        GL11.glEnd();
	        }
	        GL11.glPopMatrix();
	}
}

So, I have no idea why it doesn't work. I've moved around things, added new things, but with no result.
Any help is greatly appreciated!

Nevermind, I should have known I'd find it after I already asked for help.

I just had to use

GL11.glOrtho(position.x, position.x + Display.getDisplayMode().getWidth()/60, position.y + Display.getDisplayMode().getHeight()/60, position.y, -1, 1);
