pfpixel placement

[boski]

So I'm trying to place a pixel directly center on my sprite, but unfortunately, even with my superb mathematics knowledge, the pixel is falling well below my sprite. Can someone take a quick look and let me know if I'm missing something? Thanks!

 

 

include div_mul.asm

player0x = 30 : player0y = 30

START

 

player0:

%00111100

%00100100

%11000011

%10000001

%10000001

%11000011

%00100100

%00111100

end

 

COLUP0=$0E

COLUPF=$0E

　

if joy0up then player0y = player0y-1

if joy0down then player0y = player0y+1

if joy0left then player0x = player0x-1

if joy0right then player0x = player0x+1

a = (player0x/5)

b = (player0y/4)

if joy0fire then c = c + 1

if !joy0fire then c = 0

if c = 1 then pfpixel a b flip

drawscreen

goto START

Two programs I studied

This one uses a missile - u=(missile1y-7)/8 : v=(missile1x-13)/4

This one a sprite - a=(player1x-13)/4 : b=(player1y-1)/8

 

Try one of those. It may help.
