game map rendering or simply map rendering is a nice technique that is used to generate worlds. explanations follow suit : demo explanations 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 …
if ever you wanted to implement a polygon drawer, here it is : explanations nodes = [ [50,40], [40,50] ] first we added some coordinates as 2d arrays for i,node in enumerate(nodes): try: line(nodes[i][0], nodes[i][1], nodes[i+1][0], nodes[i+1][1]) except: pass then for each coordinate we drew a line from it to the next, the …
