hello i made this code with processing that shows a pacman eating circles and I am hoping if you can help me modify this code by having two ghosts chasing the pac man left and right. I would also be happy if you were able to make the pac man chomp. The code is shown below:

int pacX, pacY; $//$ Position of Pac$-$Man

int pacSize $=90$; $//$ Size of Pac$-$Man

int dotSize $=20$; $//$ Size of dots

int dotSpacing $=50$; $//$ Spacing between dots

int numDots $=10$; $//$ Number of dots

int score $=0$; $//$ Score

void setup$()\{$

size$(400,400)$;

pacX $=$ width $/2$;

pacY $=$ height $/2$;

$\}$

void draw$()\{$

background$(0)$;

$//$ Draw dots

for $($int i $=0$; i $<$ numDots; i$++)\{$

int dotX $=$ i $*$ dotSpacing $+$ dotSpacing $/2$;

int dotY $=$ height $/2$;

fill$(250)$;

ellipse$($dotX$,$ dotY, dotSize, dotSize$)$;

$\}$

$//$ Draw Pac$-$Man

fill$(255,255,0)$;

arc$($pacX$,$ pacY, pacSize, pacSize, $0\mathrm{.}2,$ PI $*1\mathrm{.}8)$; $//$ Chomping animation

$//$ Move Pac$-$Man

pacX $=($pacX $+1)\%$ width; $//$ Pac$-$Man moves to the right

delay$(100)$; $//$ Slow down animation

$\}$

void checkCollision$()\{$

for $($int i $=0$; i $<$ numDots; i$++)\{$

int dotX $=$ i $*$ dotSpacing $+$ dotSpacing $/2$;

int dotY $=$ height $/2$;

float distance $=$ dist$($pacX$,$ pacY, dotX, dotY$)$;

if $($distance $<$ pacSize $/2+$ dotSize $/2)\{$

score$++$;

$//$ Remove dot from the screen

$//$ Optional: You can also play a sound effect

$\}$

$\}$

$\}$

void keyPressed$()\{$

if $($keyCode $==$ UP$)\{$

pacY $-=10$; $//$ Shift Pac$-$Man up

$\}$ else if $($keyCode $==$ DOWN$)\{$

pacY $+=10$; $//$ Shift Pac$-$Man down

$\}$ else if $($keyCode $==$ LEFT$)\{$

pacX $-=10$; $//$ Shift Pac$-$Man left

$\}$ else if $($keyCode $==$ RIGHT$)\{$

pacX $+=10$; $//$ Shift Pac$-$Man right

$\}$

$\}$

void displayScore$()\{$

fill$(255)$;

textSize$(20)$;

text$("$Score: $"+$ score, $20,30)$;

$\}$
