Problem : Les unités et bâtiments ne coutaient rien à construire Solution : J'ai link le système de drag and drop au resource manager. Note : J'ai déshérité le ResourceManager de MonoBehaviour aussi, vu que c'est pas une fonctionalité qui nécessite d'être updaté par frame vraiment, c'est plus du stockage. J'ai testé dans l'éditeur et tout semble fonctionel *fingers crossed*
