Hi All, The attached files are a work-in-progress. Eventually it will become a remake of Cees Kramer's Snoopy for C64.
Anyways, the game represents an unmoveable object as a block structure. Today I decided to stop rendering the blocks for every frame. Instead they are rendered once to a background image, and then simply replace (send dc clear) with (send dc draw-bitmap the-background 0 0) in the game loop. To my surprise the frame rate dropped. It seems draw-bitmap is more expensive than I thought.? Or ... perhaps I am doing something that trips up draw-bitmap? Anyways, I have attached the game. To see the difference: Hold down the space bar. /Jens Axel -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
