Help with 7800Basic DATA Statements for Map Layout

[+frankodragon]

I'm trying to learn from the Zelda demo DATA statements to build a smaller map 6 x 8, however things aren't working right. If I move the player down, then right, the same screen repeats. I must be forgetting something. Here are my DATA statements:

      rem ** Room Definitions 48 rooms

data room_shape

2, 6, 8, 8, 8 ,8,7,7

12, 13, 8, 8, 7,14,5,5

13, 11, 8, 10, 7, 5,5,5

5, 4, 3, 3, 10,5,5,5

8, 5, 9, 12, 12 ,8,8,8

12, 10, 7, 8, 7,14,5,5

end

data room_type

1, 1, 0, 1, 1,2,1,1

2, 1, 2, 1, 1,2,1,1

2, 1, 1, 1, 1 ,1,2,2

2, 1, 2, 2, 1,2,1,1

1, 2, 2, 2, 1,1,2,1

2, 1, 2, 2, 1,2,1,1

end

data move_north

0,0,0,0,0,0,0,0

0,1,2,3,4,5,6,7

8, 9,10,11, 12,13,14

15,16, 17,18,19,20,21,22

23,24,25,26,27,28,29,30

31, 32,33,34,35,36,37,38

end

data move_south

8,9,10,11,12,13,14,15

16,17,18,19,20,21,22,23

24,25,26,27,28,29,31,32

33,34,35,36,37,38,39,40

41,42,43,44,45,46,47,48

0, 0, 0, 0, 0, 0,0, 0

end

data move_west

0,0,1,2,3,4,5,6

0,7,8,9,10,11,12,13

0,14,15,16,17,18,19,20

0,21,22,23,24,25,26,27

0,28,29,30,31,32,33,34

0,35,36,37,38,39,40,41

end

data move_east

1,2,3,4,5,6,7,0

8,9,10,11,12,13,14,0

15,16,17,18,19,20,21,0

22,23,24,25,26,27,28,0

29,30,31,32,33,34,35,0

36,37,38,39,40,41,42,0

end

Just wondering if the DATA maps needs to be an even number of rows and columns?

[RevEng]

The data doesn't need to be on even rows.

 

Just had a chance to look at this - if I walk through for "room 0" and I move down, the move_south map in position 0 says to go to room 8, so I'll wind up in room 8. If I then move right, the move_east map in position 8 says to go to room 8. So it repeats.

 

A similar sequence happens if I walk through starting with "room 1", "room 2", ...

 

You need to fix up the data in move_east to actually point to the rooms you want to move to.

Just an update..it turns out my stupid brain didn't realize I was supposed to SKIP a number in each row of the MOVE_WEST and MOVE_EAST tables.

 

For example the numbers in bold are the corrected ones:

data move_west

0,0,1,2,3,4,5,6

0,8,9,10,11,12,13,14

0,16,17,18,19,20,21,22

0,24,25,26,27,28,29,30

0,32,33,34,35,36,37,38

0,40,41,42,43,44,45,46

end

I guess you could replace the zeroes with their standard numbers but I used the code from the Adventurer demo.
