Pygame : jeu de Serpent de la Façon de faire de faire de serpent aller à travers les murs ou la création d'un cadre autour du bord?

J'ai essayé dernièrement de faire un dessin sur la paroi comme bien ou de faire le serpent de ce jeu pour passer à travers le mur, mais je ne sais pas comment le programmer. Si quelqu'un a une idée de comment faire le serpent passer à travers le mur ou le dessin d'une image sur le bord pourriez-vous s'il vous plaît aidez-moi comment le programmer ? et si il n'y a aucune recommandation pour ajouter ce jeu, pourriez-vous s'il vous plaît ajouter ici. Ce sont les codes :
