Bonjour
Pour apprendre à utiliser la SFML, je suis entrain de réaliser un shoot em up trés simple mais j'ai un léger probleme.
Lorsque je touche le premier bloc ( je peux toucher les autres sans probleme ) , la fonction erase se déclenche et au lieu de supprimer le bloc, elle change les coordonnées x de tout mes blocs ce qui cause la fin de la partie.
Ce probleme n'arrive que lors du lancement de l'appli. Si je relance une partie sans fermer l'appli tout se passe correctement.

PS : je sais que le code est très salle et que ce n'est surement pas les bonnes techniques, ce sont juste des essais
