Exemple d'analyse de code C# pour implémenter le jeu Snake

Cet article analyse principalement le code d'implémentation du C#Jeu Snake pour tout le monde. Il a une certaine valeur de référence. Les amis intéressés peuvent s'y référer

L'incident ennuyeux d'aujourd'hui que je veux être. un serpent gourmand Bien qu'il existe beaucoup de choses de ce type sur Internet, je pense que c'est bien de l'écrire moi-même

Analyse du serpent

Règles du jeu :

1. La longueur de départ du serpent est de 5, chaque aliment consommé augmente de 1, et le maximum est de 15 pour passer le niveau

2. . Le serpent est représenté en bleu, utilisez le vert pour la nourriture et le noir pour les obstacles

3. Lorsque le serpent se touche, un mur ou un obstacle, le jeu échoue

4. Le serpent. les touches de direction contrôlent la direction du mouvement du serpent, et le serpent ne peut pas bouger dans la direction opposée. Déplacez-vous, si vous montez, vous ne pouvez pas descendre immédiatement, vous ne pouvez vous déplacer que vers la gauche, la droite et le haut

. 5. La vitesse augmente à chaque fois que vous passez un niveau

Idée générale :

1 La carte est représentée dans. sous la forme d'une grille. Le serpent est composé de carrés et est stocké dans une liste

2. Le carré est mentionné en 1. Le contenu enregistré dans le carré comprend la couleur, les coordonnées, si ça peut passer, et si c'est de la nourriture

3. Avancez une fois et ajoutez le carré précédent à la liste des serpents Supprimez le dernier de la liste Si la grille avant est de la nourriture, la dernière ne le fera pas. être supprimé

4. Utilisez whiledeadloop pour effectuer l'intégralité du mouvement

5 La barre d'espace est une touche d'accélérateur. en modifiant la boucle while temps de veille

comprend 3 classes et une forme principale, à savoir Node (utilisé pour représenter Square), Map (utilisé pour représenter une carte). ), Serpent (utilisé pour représenter un serpent) et une autre forme principale. Collez le code ci-dessous dans l'ordre. En gros, chaque méthode a un commentaire
