Overriding the DoDraw Procedure

[Cer3brus]

When creating a class in delphiX for a character and, for instance, I wanted to draw the sprite rotated at an angle using the sprite engine, my code looked as follows:

 THero = class(TImageSprite)
  Speed : Integer;
  Public
   Procedure DoMove(MoveCount: Integer); override;
   procedure DoCollision(Sprite: TSprite; var Done: Boolean); override;
   Procedure DoDraw; override;
  end;

It works... but the sprite gets drawn twice!! Once rotated and once normal. I probably set up the DoDraw incorrectly
Any ideas?
