Math error

[jbs30000]

I remember from another thread that you sometimes have to sometimes do math a little differently....for example

Misc2=(player1y-24)/18

is giving me an error: div8 0000 ???? (R )

I tried going

Misc2=(player1y-24)/(9*2)

and

Misc2=(player1y-24)/(6*3)

But got the same error. So, how do I fix this? Thank you.

Also, the game is multi-bank and include div_mul.asm doesn't work.

It looks like you need to specify the include file before the romsize, or it won't include the include file:

 

   include div_mul.asm
  set romsize 8kSC

An alternative would be to create a custom includesfile that includes div_mul.asm in it, which would also let you omit any unnecessary include files that you might not need-- e.g., pf_drawing.asm and pf_scrolling.asm:

 

; my_bankswitch.inc
;
; This is a customized version of the bankswitch.inc file.
;
2600basicheader.asm
bB.asm
std_kernel.asm
startup.asm
div_mul.asm
std_routines.asm
std_overscan.asm
bB2.asm
score_graphics.asm
banksw.asm
2600basicfooter.asm

Then, at the beginning of your program:

 

   includesfile my_bankswitch.inc
  set romsize 8kSC

I put include div_mul.asm before set romsize, and it worked. Thank you very much.
