Put the Tbricks in an array with dimensions the width/height of your 'wall'. Then keep track of screen_offset and draw from that index to the number of bricks that can fit on a screen.
no sure to understand your idea. Is it this :
use an one dimension array, determine an index for each tile ? i've thinking about this idea to direct access to a tile. The problem is that produce a huge array...
32 x 24 x 1000. with a lot of null values (have not a tile for each array cell).
Not that the previous editor screen is a test, there are no 'walls' into the game. See the ingame screenshoot picture.
