Converting to a scrolling tile engine....ABSURD!
 

Well I feel I am trying to do something very foolish. I want to change my game engine from a room by room deal, to a scrolling tile engine. I want to walk from one map into the other witht he effect of a seamless transition.

I've done some research and I have decided to load up 9 maps in a 3 by 3 grid. Unfortunately i can't figure out how i'm going to handle rendinger parts of lets say if i am inbetween the top and middle row and moving left. As of now it loads the data from the txt files into ana rray and then renders it on a surface. I am thinking of rendering all 9 maps onto 1 surface at a time.

Anyhow how would i achieve rendering the maps while there can be parts of 4 different maps visible at once?

as of now it works within the 9 maps loaded, I notice some performance drops now since its not room by room anymore. I do not know which type too keep. Also lines apear across the screen sometimes during the time its scrolling if you scroll for a while.

anyhow if you are interested to know how i did it i kept track of another 2 x and y variables that tell the engine where to start drawing the visible area of the map

Makes sense to me. If you see some code that's really slowing it down, post it here and we can try and optimize it.

Yeah it is getting slowed down sometimes because if i amc onstantly moving in one direction where it starts too scroll at the edge, it will slow down sometimes.

Other htan that i think its doing ok. I will definitely need help optimizing it soon.
