hello I made a game of pac man and the ghost models i used were not good enough. My teacher gave me this code to replace the $2$ ghost models but I dont know how to add it to my code.

MODEL FOR THE TWO GHOSTS:

PShape ghost, eyes;

void setup$()\{$

size$(500,200)$;

ghost$=$loadShape$("$ghost$.$svg$")$;

eyes$=$loadShape$("$eyes$.$svg$")$;

$\}$

void draw$()\{$

$//$Draw default svg ghost to left with reduced$-$size eyes on top

ghost.enableStyle$()$;

shape$($ghost$,0,0)$;

shape$($eyes$,50,30,100,100)$;

$//$Disable style of ghost and draw same ghost and eyes to right

ghost.disableStyle$()$;

shape$($ghost$,150,0)$;

shape$($eyes$,200,30,100,100)$;

$//$Change fill to red and draw same ghost and eyes to right

fill$(255,0,0)$;

shape$($ghost$,300,0)$;

shape$($eyes$,350,30,100,100)$;

noFill$()$;

$\}$
