Exercice 2 : Déplacement véhicule - Fonctions - Utilisation d'une fonction avec paramètres (5/8)

Les fonctions peuvent avoir des arguments. Cela permet aux fonctions d'avoir un fonctionnement générique. À l'intérieur d'une fonction, un paramètre est une variable qui peut être utilisée librement.

Placez le véhicule devant la tour en utilisant le bloc qui appel la fonction avec le paramètre 7 et observez l'éxécution de la fonction..
