game map rendering or simply map rendering is a nice technique that is used to generate worlds.

game_map = [ [0,0,0,0,0], [0,1,0,1,0], [0,0,1,0,0], [0,1,0,1,0], [0,0,1,0,0], ]
first we initialise our world as a 2d array, we distinguished patterns by using 0 and 1
tile_width = 50
next we initialised the width of a tile. the formula for tile placement is x*tile_width
def green_tile(x, y): fill(0,255,0) rect(x, y, tile_width, tile_width) def white_tile(x, y): fill(255) rect(x, y, tile_width, tile_width)
next we separated our tile rendering in two functions, for now it’s just colored squares
for r in range(map_length): for c in range(map_length):
we loop or the array twice, one for the row and one for the column to get the index to accesss our map by game_map[x][y]
if game_map[c][r] == 0: # inversed for viewing as is in variable green_tile(r*tile_width, c*tile_width) elif game_map[c][r] == 1: white_tile(r*tile_width, c*tile_width)
here we render according to predefined symbols, it could have been ‘g’ and ‘p’ for grass and path
