I'm making a maze program and I wasn't sure how to go about storing the mazes. I could put a list of sprite x and y coordinates for the maze walls in a dat file and load them into an array in the program, but how would I do that? I was also wondering (because of the 512 management number limit) if I could make a map in SBMAP and load that in and have it detect collision with that (but I'm not sure it's possible). Any ideas?
Help with maze program
One way to store mazes is in a 2-dimensional array. For array entry [x,y], store a 0 if the square x paces East and y paces South from the North-West corner is a 'floor' square, and store a 1 if it is a 'wall' square. If your maze has other features that are affixed to squares (such as, an exit, or a trap, or a shop), you can use the same array. You can even store temporary features of the maze: e.g. use the value 2 to indicate this square contains treasure, or a sword, and when the player steps on that square, update the player's status and overwrite the 2 with 0.
If you use map, you can use a layer to store collision and other stuff. For example, in my platform program, I use the map to store collision with the background cell "C" on the layer 3, then on the layer behind it I put a wall, floor, etc.
To check if a sprite is touching a background cell, use BGGET.
Also, I don't recommend using the sprites to create the map because 512 sprites is a low number. Beside, if you'll plan use both the upper and lower screen, keep in mind that you still has 512 sprites in total.
