Codage, ; enfants Faire_un_atelier_avec_Scratch_scratch.jpg
Scratch est une application ludique permettant d'apprendre les bases du codage informatique simplement. Bien qu'il s'adresse avant tout à un public enfantin, Scratch peut-être utilisé par n'importe qui souhaitant s'essayer à ce sujet.
On peut réaliser des films, de la musique et aussi des jeux vidéo.
Déjà souvent employé dans le milieu scolaire, il permet des possibilités d'animations riches et variées.1 : La page d'accueil du site offre un design coloré et enfantin.
2 : Vous accédez à la partie création.
3 : Vous accédez à l'ensemble des créations de la communauté
4 : Vous accédez aux tutoriels pour apprendre à se servir de Scratch.
5 : Vous devez créer un compte afin de sauvegarder vos créations.
Voici la page du menu de création :
1 : Scratch utilise une ligne de codage simple à base de blocs à empiler.
2 : L'écran où on aligne les blocs de programmations. Il faut les empiler les uns sur les autres pour faire une suite d’événements.
3 : L'animation à réaliser s'affiche dans le coin supérieur droit de l'écran. Le petit drapeau vert situé au-dessus permet de démarrer l'animation.
4 : L'écran on peut choisir des "Sprites" (icônes en forme de personnages ou d'objet) et des fonds d'écrans.
5 : Ce menu permet de naviguer entre la page de codage, celle de modification des Sprites ou de gérer les fonds sonores.
Voici à quoi ressemble la base de données des "Sprites" de Scratch.
On peut les filtrer en catégories et faire une recherche manuellement.
Tous les Sprites peuvent être modifiés à sa convenance. Il faut appuyer sur le Sprite à modifier puis à appuyer dans la rubrique"costumes" en haut à gauche de l'écran.
On peut aussi modifier une scène en cliquant dessus et en allant dans la rubrique "arrière-plans" en haut à gauche de l'écran.
Les outils sont légèrement différents de ceux des Sprites. On peut ici sélectionner une partie du dessin pour l'effacer ou la déplacer avec l'outil "sélectionner".
On peut choisir l'orientation de l'arrière-plan ou copier-coller une partie.
Pour modifier un son sur Scratch, aller dans la rubrique "sons" en haut à gauche de l'écran de création.
1) Les blocs sont répartis par catégories, qui ont des couleurs différente :
2) Pour utiliser un bloc, vous devez le faire glisser jusque dans la partie centrale de l'écran de création en maintenant le clic gauche de la souris. Il faut ensuite les empiler verticalement, et du haut vers le bas.
3) Pour démarrer votre ligne de code, vous devez toujours mettre au début du code le bloc "quand drapeau vert est cliqué", vous le trouverez dans la partie "événements" en jaune.
Une fois que vous avez terminé votre code, appuyez sur le drapeau vert pour lancer l'animation. Cette étape permet de vérifier si le code fonctionne et que le résultat est bien celui que l'on attendait. Le bouton rouge à coté du drapeau permet de mettre en pause l'action.
