TNSI : POO, Tutoriel Pygame

Voici quelques tutoriels vidéos sur YouTube conseillés.

TNtube - Apprendre Pygame de A à Z

Episode 1 : Introduction, Installation et Première Fenêtre

Boucle de Détection des Événements:

import pygame
pygame.init()

# Générer la fenêtre du jeu
pygame.display.set_caption("Shoot'em Up")
screen = pygame.display.set_mode((1080,720))

running = True

while running:
    # boucle de détection des événements
    for event in pygame.event.get():
        # si l'événement est une fermeture de fenêtre
        if event.type == pygame.QUIT:
            running = False
pygame.quit()

Episode 2 : Image, Événements, Déplacements

Boucle des Événements SANS Répétitions

import pygame

pygame.init()
screen = pygame.display.set_mode((400,400))
running = True

image = pygame.image.load("ball.png").convert()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:
                print("Gauche !")
            if event.key == pygame.K_RIGHT:
                print("Droite !")
            if event.key == pygame.K_UP:
                print("Haut !")
            if event.key == pygame.K_DOWN:
                print("Bas !")

    screen.blit(image, (0,0))
    pygame.display.flip()

pygame.quit()

Boucle des Événements AVEC répétitions

La fonction pygame.event.get_pressed() renvoie un dictionnaire {pygame.K_a: 0, pygame.K_b:0, pygame.K_c:0, ...} dont les valeurs sont :

• soit 0 pour une touche NON appuyée
• soit 1 pour une touche APPUYÉE

Cette fonction fonctionne uniquement avec les touches du clavier.

import pygame

pygame.init()
screen = pygame.display.set_mode((400,400))
running = True

image = pygame.image.load("ball.png").convert()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    pressed = pygame.key.get_pressed()
    if pressed[pygame.K_LEFT]:
        print("Gauche !")
    if pressed[pygame.K_RIGHT]:
        print("Droite !")
    if pressed[pygame.K_UP]:
        print("Haut !")
    if pressed[pygame.K_DOWN]:
        print("Bas !")

    screen.blit(image, (0,0))
    pygame.display.flip()

pygame.quit()

Balle se déplaçant en 60fps (au lieu de 5000fps par défaut)

import pygame

pygame.init()
screen = pygame.display.set_mode((400,400))
running = True

image = pygame.image.load("ball.png").convert()

x = 0
y = 0

clock = pygame.time.Clock()

while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    pressed = pygame.key.get_pressed()
    if pressed[pygame.K_LEFT]:
        x -= 1
    if pressed[pygame.K_RIGHT]:
        x += 1
    if pressed[pygame.K_UP]:
        y -= 1
    if pressed[pygame.K_DOWN]:
        y += 1

    screen.fill((0,0,0))
    screen.blit(image, (x,y))
    pygame.display.flip()
    clock.tick(60)
pygame.quit()
