Ich habe ein Raster wie das Bild, unter dem ich ein Array in diesem Format einfügen möchte:

 ;x = wall(black cells and grey boxes), s= start (red circle), g = goal(blue circle), 0 = available path(everything else)
 $data[5][5] = [["x","x","x","x","x"], _
               ["x","s","0","x","x"], _
               ["x","x","0","x","x"], _
               ["x","x","0","g","x"], _
               ["x","x","x","x","x"]]

Ich dachte, ich könnte die Farben verwenden, aber ich bin nicht sicher, wie.
