Tutoriel Pygame Code de base Pour utiliser le module Pygame il faut l'importer au début du programme. import pygame as pg Cependant, si on exécute tel quel le programme dans un navigateur un fenêtre va apparaître mais elle ne pourra être fermée.
Il faut pour cela écrire plusieurs autres ligne : import pygame as pg pg.init() pg.display.set_caption("Pygame") fin = False while not fin: ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit()

• pg.init() permet d'initialiser la fenêtre Pygame.
• pg.display.set_caption("Pygame") affiche un titre pour la fenêtre Pygame.
• fin = False définit une variable booléenne (ici fausse) qui permettra de déclencher l'arrêt du programme.
• La boucle while s'exécute tant que la variable fin est fausse. Ainsi à chaque tour de boucle la variable ev, qui attend de voir qu'elle évènement peut survenir, sera associée à l'évènement QUIT lorsqu'on clique sur la croix de la fenêtre. À ce moment la variable fin devientVraie et on quitte donc la boucle pour exécuter la commande pq.quit() qui permet de fermer la fenêtre Pygame.

Ainsi, c'est dans cette boucle que se dérouleront toutes les actions d'un jeu. On l'appelera la boucle Pygame. Dessiner dans la fenêtre Pygame Dimensions de l'écran Pour définir les dimensions de la zone dans laquelle le jeu va se dérouler on utilise l'instruction pg.display.set_mode((largeur, hauteur)).
Dans l'exemple ci-dessous la fenêtre aura pour dimension 400px par 150px. import pygame as pg pg.init() pg.display.set_caption("Pygame") ecran = pg.display.set_mode((400, 150)) fin = False while not fin: ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Couleur de l'écran La variable ecran ainsi créée va pouvoir être utilisée pour attribuer des propriétés à la fenêtre de jeu. Par exemple pour donner une couleur de fond : import pygame as pg pg.init() pg.display.set_caption("Pygame") ecran = pg.display.set_mode((400, 150)) vert = (0,255,200) fin = False while not fin: ecran.fill(vert) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Segment Pour tracer un segment on utilise l'instruction pg.draw.lines( display, couleur, fermeture (True ou False) , [(abs1,ord1), (abs2,ord3), etc. ] ) : import pygame as pg pg.init() pg.display.set_caption("Pygame : ligne") ecran = pg.display.set_mode((400, 150)) vert = (0,255,200) fin = False while not fin: ecran.fill(vert) pg.draw.lines(ecran, [0,0,0], False, [(0,0),(200,50)], 1) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit()
import pygame as pg pg.init() pg.display.set_caption("Pygame : lignes") ecran = pg.display.set_mode((400, 150)) vert = (0,255,200) fin = False while not fin: ecran.fill(vert) pg.draw.lines(ecran,[255,0,0],True,[(0,130),(200,50),(220,80),(250,60)],5) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Rectangle Pour tracer un rectangle on utilise l'instruction pg.draw.rect( display, couleur, [abs, ord, largeur, hauteur], épaisseur ) : import pygame as pg pg.init() pg.display.set_caption("Pygame : rectangle") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.rect(ecran,[255,150,150],[150,25,100,100]) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Cercle Pour tracer un cercle on utilise l'instruction pg.draw.circle(display, couleur, (abs,ord), rayon, épaisseur) : import pygame as pg pg.init() pg.display.set_caption("Pygame : cercle") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.circle(ecran,[0,0,0],[200,75],30,3) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit()
import pygame as pg pg.init() pg.display.set_caption("Pygame : cercle") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.circle(ecran,[0,0,0],[200,75],30,0) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit()
import pygame as pg pg.init() pg.display.set_caption("Pygame : cercle") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.circle(ecran,[255,0,0],[200,75],30,0) pg.draw.circle(ecran,[0,0,0],[200,75],30,4) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Ellipse Pour tracer une ellipse on utilise l'instruction pg.draw.ellipse(display, couleur, (abs,ord,largeur,hauteur), épaisseur). import pygame as pg pg.init() pg.display.set_caption("Pygame : ellipse") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.ellipse(ecran,[0,0,0],[150,30,100,80],2) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit()
import pygame as pg pg.init() pg.display.set_caption("Pygame : ellipse") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.ellipse(ecran,[0,0,0],[150,30,100,80],0) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Arc d'ellipse Pour tracer un arc d'ellipse on utilise l'instruction pg.draw.arc(display, couleur, (abs,ord,largeur,hauteur), angle de départ, angle de fin, épaisseur). Les angles sont exprimés en radians. import pygame as pg pg.init() pg.display.set_caption("Pygame : arc") ecran = pg.display.set_mode((400, 150)) vert = (0,255,100) fin = False while not fin: ecran.fill(vert) pg.draw.arc(ecran,[0,0,0],[150,30,100,80],0,3.14159,2) pg.display.update() ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Écrire du texte Pour écrire du texte il faut tout d'abord importer le module pygame.font et ensuite initialiser la prise en charge des polices de caractères avec pg.font.init().
On peut définir alors une police avec dans le code ci dessous l'instruction myfont = pg.font.SysFont('Arial', 30). La police s'appelle myfont et elle utilise Arial (mais on peut saisir celle que l'on souhaite) et la taille des caractères est de 20px.
On définit une surface sur laquelle on écrit avec l'instruction textsurface = myfont.render('GAME OVER', False, (0, 0, 200)) qui crée la surface textsurface sur laquelle on écrit « GAME OVER » avec la couleur (0,0,200) qui correspond à du bleu.
Pour ajouter cette surface à notre fenêtre Pygame on saisit ecran.blit(textsurface,(30,80)) pour la placer à l'abscisse 30 et l'ordonnée 80. import pygame as pg import pygame.font pg.font.init() myfont = pg.font.SysFont('Arial', 20) pg.init() pg.display.set_caption("Texte") ecran = pg.display.set_mode((200, 200)) textsurface = myfont.render('GAME OVER', False, (0, 0, 200)) ecran.blit(textsurface,(30,80)) pg.display.update() fin = False while not fin: ev = pg.event.wait() if ev.type == pg.QUIT: fin = True pg.quit() Animations import pygame as pg pg.init() pg.display.set_caption("Animation") clock = pg.time.Clock() ecran = pg.display.set_mode((400, 150)) x = 10 dx = 5 while True: clock.tick(20) ecran.fill(pg.Color("black")) x += dx pg.draw.circle(ecran,[255,255,255],[x,75],10,0) pg.display.update() for e in pg.event.get(): if e.type == pg.QUIT: pg.quit() pg.quit()
