Hi All,
I am trying to draw a sprite to the screen. So far, when making small games I have loaded textures and drawn them in a very un-OO way and just used OO techniques for the game mechanics. Now, I wanted to load the textures in to the object and draw them from their own method too. I wrote what I thought would work but the sprite is not being drawn to the screen. The background get drawn fine and there are no compile or runtime errors. Can someone spot what I am doing wrong please?
