Re: A86: String Centering Routine?
you want to center horizontally?
well, first you need to get the width of the string (you're using the
small font, right?)
one way of doing that is to call up the width of each char and add them.
if you're not using the graph buffer, though, try this:
;hl->string
;returns: a=width
string_width:
xor a
ld (_penCol),a
res textwrite,(iy+new_grf_flgs) ;don't draw to lcd
call _vputs
ld a,(_penCol)
set textwrite,(iy+new_grf_flgs)
ret
then subtract the width of the string from the screen width and divide by
two
ld b,-128
add a,b
sra a
that's the column to start in
now all you have to do is find the corresponding flag for the 83!
