Bonjour, je me suis récemment lancé dans un projet de casse brique en java et je suis en proie à un bug que je n'arrive pas à identifier/réctifier. (Au passage, je commence tout juste la programmation par moi-même, je n'ai pas pris de cours en java).
Je vous présente mon problème :
Lorsque la balle arrive en dessous d'une brique, au milieu de celle-ci, elle réagit normalement: casse la brique et repart. Mais lorsqu'elle atteint une brique dans l'extrémité, elle casse la brique mais ne repart pas donc casse une deuxième brique et il se peut qu'elle se fasse un chemin à travers les briques alors que ce n'est normalement pas possible.
voici mon code :
Code : Sélectionner tout - Visualiser dans une fenêtre à part
