Your program is not using the traditional Pacman method, it makes things easier. You can use the distance formula for your collision.

Use your x,y Pacman pos for x1,y1, and your dot positions for x2,y2


function distance(x1,x2,y1,y2)
endfunction sqrt(((x2-x1)^2)+((y2-y1)^2))

I used sprite for my pac-man and pills

I did this

for dispills=# to #
if sprite collision (pacmannumber,dispills)>0 then hide dispills
next dispills

change the hashes by the start number pills sprite to the final pill
