I have an issue with my code, It is about pac man but the ghosts wont follow the pacman and there are not enough dots on the screen. After i get a few dots, they do not respawn and the game does not end when the pac man colides with the ghosts despite me making a code for it$.$

here is my code for the game:

PShape ghost$1,$ ghost$2,$ eyes$1,$ eyes$2$;

pacY $=$ height $/2$;
