Comments or Suggestions for newbie game?

Have you posted this in the batari Basic forum yet? I know you haven't included the code for us to look at, but the other batari Basic programmers would probably enjoy trying out the game and offering batari Basic programming examples.

What's the easiest way of having a new playfield come? For example, I want player0 to reach the end of the screen, which will prompt the new screen.

This is a very basic example, and there are surely better ways to do it, but I want to keep it simple.

   rem * example of moving between rooms

   dim room_number = a
   dim movement = b

   room_number = 1 : rem so you can go left or right from the start

   movement = 0 : rem not moving yet

   COLUBK = $00 : rem black

   player0:
   %11000011
   %01100110
   %00111100
   %00011000
   %00011000
   %11111111
   %00011000
   %00011000
end

   player0x = 17
   player0y = 64

main_loop

   COLUP0 = $3A : rem peach

   player0x = player0x + movement : rem move player0

   on room_number gosub room0 room1 room2 : rem draw the room

   drawscreen : rem draw the screen

   if collision(player0,playfield) then player0x = player0x - movement
   rem knock player0 back if collided with playfield

   movement = 0 : rem reset movement before checking joystick
   if joy0left then movement = 255 : rem 255 is equal to -1 (left)
   if joy0right then movement = 1 : rem 1 is equal to +1 (right)

   if player0x = 16 then gosub room_to_the_left
   if player0x = 137 then gosub room_to_the_right

   goto main_loop

room0

   COLUPF = $1C

   playfield:
   ................................
   ................................
   ................................
   ................................
   ................................
   ................................
   X...............................
   X...............................
   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   ................................
   ................................
end

   return

room1

   COLUPF = $4C

   playfield:
   ................................
   ................................
   ................................
   ................................
   ................................
   ................................
   ................................
   ................................
   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   ................................
   ................................
end

   return

room2

   COLUPF = $8C

   playfield:
   ................................
   ................................
   ................................
   ................................
   ................................
   ................................
   ...............................X
   ...............................X
   XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
   ................................
   ................................
end

   return

room_to_the_left

   room_number = room_number - 1

   player0x = 136

   return

room_to_the_right

   room_number = room_number + 1

   player0x = 17

   return

Basically, you can check the player's x coordinate to see if he's moved to a point where you want the screen to change. You would also want to make him disappear off of one side and reappear on the other side-- i.e., if he moves off the left edge of one screen, he would end up near the right edge of the new screen, or vice versa.

Also, does the AA store make 8K custom carts? This, when finished, definently won't fit 4k.

You should PM Albert and ask him. If he can't accommodate you, there are also other places where you can get your games made into cartridges.

PS -- In your game, pressing fire continuously causes the man to "levitate." There should be some examples of programming a jumping/falling sprite with "gravity." My little example has no vertical movement or jumping/falling/gravity, just horizontal motion.
