XNA C# Help with HUD

I had my HUD drawn to the screen and it's Vector2 set to the camera's position, HUD followed along with the camera just fine. I then went ahead and created a class just for the HUD, but it doesn't seem to get the camera's position now. using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Xna.Framework; using Microsoft.Xna.Framework.Graphics; using Microsoft.Xna.Framework.Input; using GameOne.Components; namespace GameOne.GameScreens { public class HUD : BaseGameState { Player player; Texture2D HealthBar; Texture2D HealthBarPositive; Texture2D HealthBarNegative; Texture2D ManaBar; Texture2D ManaBarPositive; Texture2D ManaBarNegative; Texture2D ExpBar; Texture2D ExpBarPositive; int CurrentHealth = 100; int CurrentMana = 45; int CurrentExp = 0; public HUD(Game game, GameStateManager manager) : base(game, manager) { player = new Player(game); } public void LoadContent() { base.LoadContent(); HealthBar = Game.Content.Load<Texture2D>(@"GUI\healthBar"); HealthBarPositive = Game.Content.Load<Texture2D>(@"GUI\healthBarPositive"); HealthBarNegative = Game.Content.Load<Texture2D>(@"GUI\healthBarNegative"); ManaBar = Game.Content.Load<Texture2D>(@"GUI\manaBar"); ManaBarPositive = Game.Content.Load<Texture2D>(@"GUI\manaBarPositive"); ManaBarNegative = Game.Content.Load<Texture2D>(@"GUI\manaBarNegative"); ExpBar = Game.Content.Load<Texture2D>(@"GUI\expBar"); ExpBarPositive = Game.Content.Load<Texture2D>(@"GUI\expBarPositive"); } public override void Update(GameTime gameTime) { if (InputHandler.KeyDown(Keys.F1)) { CurrentHealth += 1; } if (InputHandler.KeyDown(Keys.F2)) { CurrentHealth -= 1; } if (InputHandler.KeyDown(Keys.F3)) { CurrentMana += 1; } if (InputHandler.KeyDown(Keys.F4)) { CurrentMana -= 1; } if (InputHandler.KeyDown(Keys.F5)) { CurrentExp += 1; } if (InputHandler.KeyDown(Keys.F6)) { CurrentExp -= 1; } CurrentHealth = (int)MathHelper.Clamp(CurrentHealth, 0, 100); CurrentMana = (int)MathHelper.Clamp(CurrentMana, 0, 45); CurrentExp = (int)MathHelper.Clamp(CurrentExp, 0, 500); } public override void Draw(GameTime gameTime) { GameRef.SpriteBatch.Draw( HealthBarNegative, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 630, 150, 15), Color.White); GameRef.SpriteBatch.Draw( HealthBarPositive, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 630, 150 * (int)CurrentHealth / 100, 15), Color.White); GameRef.SpriteBatch.Draw( HealthBar, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 630, 150, 15), Color.White); GameRef.SpriteBatch.Draw( ManaBarNegative, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 650, 150, 15), Color.White); GameRef.SpriteBatch.Draw( ManaBarPositive, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 650, 150 * (int)CurrentMana / 45, 15), Color.White); GameRef.SpriteBatch.Draw( ManaBar, new Rectangle((int)player.Camera.Position.X + 150, (int)player.Camera.Position.Y + 650, 150, 15), Color.White); GameRef.SpriteBatch.Draw( ExpBarPositive, new Rectangle((int)player.Camera.Position.X + 10, (int)player.Camera.Position.Y + 680, 1260 * (int)CurrentExp / 500, 15), Color.White); GameRef.SpriteBatch.Draw( ExpBar, new Rectangle((int)player.Camera.Position.X + 10, (int)player.Camera.Position.Y + 680, 1260, 15), Color.White); } } }

    	public override void Draw(GameTime gameTime)

    	{

        	GameRef.SpriteBatch.Begin(

            	SpriteSortMode.Deferred,

            	BlendState.AlphaBlend,

            	SamplerState.PointClamp,

            	null,

            	null,

            	null,

            	player.Camera.Transformation);



        	map.Draw(GameRef.SpriteBatch, player.Camera);



        	sprite.Draw(gameTime, GameRef.SpriteBatch, player.Camera);



        	hud.Draw(gameTime);



        	base.Draw(gameTime);



        	GameRef.SpriteBatch.End();

    	}

I found out that I was constantly drawing the spritefont every frame.
Is there anyway I can work around this? Just like what I did with my status bars.
Or is there an alternative to using Camera Transformation for my positions?
