J'ai des problèmes avec ma détection de collision. En fait, lorsque je frappe une tuile solide, le corps de mon personnage est déjà à mi-chemin dans la tuile. Voici mon code.
Les propriétés wY et wX sont le positionnement de mon univers de jeu. Pas le positionnement de la scène. dx et dy sont la vitesse à laquelle le personnage se déplace. Ce premier bout de code se trouve dans une boucle de jeu. Le point focal de mon personnage est centré sur l'axe x.
