Bonjour je suis nouveau voila je me suis lancer dans l'aventure de créer un mini editeur de map 2d iso avec la SFML
Mes je rencontre quelque petit soucis, je ne sais pas comment redimensionner mes sprite(tiles) par rapport à ma grille isométrique?

j'arrive à construire la grille correctement j'arrive a récupéré la celulle ID et c'est cordonnée par rapport la cellule que ma souris traverse!
j'ai mis en pièce joint le tile que j'utilise est son rendue!
J'espère pouvoir avoir de l'aide de votre par merci d'avance!
Bonne Année!
