thanks for your reply Goran Milovanovic & slicksk8te.
i already know python, but just basic and still learning. i also been learning pygame
for 3weeks now. i still not comfortable with it but making a good progress with it day by day.
just wanna have some fun while learning python / pygame,i would like to try to create
a simple platform / tile-system in 2d.

i want to know in general, how do people setup the game screen, especially the background,
starting on how they create the map for each level, load it with the sprite, mark it / flag each
sprite ( is it a wall or not, etc). this is the only thing i want to know for the this time. i need to know
the basic how in general, the concept behind this platforming tile-based game.

thanks again, and hope you can give me some idea ;)

hi,

thanks for your quick reply. i manage to solve this problem. but i dont know is it the right way of doing this for tile based game.
any way this is my new code. i just draw a rectangle before i draw the tile map, then i use the rectangle for collision detection. is it correct?
