bAtariBasic DataStatement Wierdness

[Joel D. Park]

Guys,

 

I'm working on a game in bAtariBasic.

I had a bunch of space left on my cart so I decided to add some title music.

I'm getting a wierd thing however with a data statement.

 

When I add a data statement see (musicdata), it shifts my playfield over for my bonus round.

If you delete the bottom line of the musicdata data it will shift back. To get to the bonus, kill the bear once, then the next level, you'll notice the 4 holes in the middle aren't in the right places.

 

default.bas

 

Is there something special I need to do to keep this from happening???

 

Thanks,

Joel

Here's the binary if that helps.

I'm not sure what's going on in your program. Have you tried this for making music and sound effects yet:

I think you need to get an updated version of bB.

 

When I play your bin, the holes are definitely in the wrong place. But I built your source from scratch without modification, and the holes are in the right place.

Additional thought - you're likely running into a page boundary bug.

 

Try adding a dummy data statement with 16 or 32 zeros in front of your bonus playfield and see if the problem goes away.

When I compile the code without changing it, I get the same results as you. But when I delete the blank line between the last line of music data and the end statement, it compiles correctly. I don't think the compiler likes that blank line.

 

This is okay:

 

   data musicData
   12,20,10, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
   0,-1,10, 12,20,5, 0,-1,5, 12,20,5, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
   0,-1,10, 12,20,5, 0,-1,5, 12,20,5, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
end

This is not okay:

 

   data musicData
   12,20,10, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
   0,-1,10, 12,20,5, 0,-1,5, 12,20,5, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
   0,-1,10, 12,20,5, 0,-1,5, 12,20,5, 6,-1,5, 12,18,10, 0,-1,10, 12,17,10, 0,-1,10, 12,15,10, 0,-1,10
