Pygame et path finding

Bonjour,

J'ai pour projet de créer un programme de path finding en python. J'ai rencontré un problème dans la fonction find_path dans le if (ligne 48) : la fonction find_path.add_block() ne fonctionne pas... alors que si je mets un print, il s'affiche

Pourriez-vous m'aider a résoudre ce problème voir à améliorer mon programme ?

Merci
