I have a question...I am making a platformer that (obviously) uses side scrolling... Now, I would like to use parallax scrolling but it is very difficult (well not really, but it does take longer)...so, I thought I would keep it simple and use Mode 13H...use a virtual bitmap and just blit it to the screen...this would serve as a scroller and a double buffer.. Here is the potential problem...using a screen of 3200x200 (10 screens wide) the memory would require 640,000 bytes! The good news is that this method makes it VERY easy to program and there is less drawing (I would just blit the entire map at once then blit the portions to the screen). The bad news is the huge memory requirements...however, I am using 8 megs for the game so that it might not be a problem after all... What is your opinion? Please respond with lots of opinions...it helps my judgement of where I should go with this... Thanks... PS -> it's a sci-fi platformer... -- ********************************************************** ---SuperNova Software--- * Making Games FUN Again! * metroid AT cdc DOT net ------(C.B.
