Définition de l’espace de jeu (création de l’échiquier) :

import pygame

pygame.init()
ecran=pygame.display.set_mode((640,640))

continuer = True
while continuer :
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            continuer = False
    pygame.display.flip()
pygame.quit()

Programme pour mettre de la couleur aux cases :

import pygame
blanc=(255,255,255)
noir=(0,0,0)
jaune=(255,255,0)
cases=80

pygame.init()
ecran=pygame.display.set_mode((640,640))
pygame.draw.rect(ecran,blanc, (0,0,cases,cases))
pygame.draw.rect(ecran,jaune,  (80,0,cases,cases))
continuer = True

while continuer :
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            continuer = False
    pygame.display.flip()
pygame.quit()

Programme pour remplir avec des couleurs les cases de tous l’échiquier :

import pygame
import random
n,p=8,8
violet=(255,0,255)
jaune=(255,255,0)
cases=80
def damier():
    for i in range (8):
        for j in range (8):
            if (i+j)%2==1:
                pygame.draw.rect(ecran,violet, (cases*i,cases*j,cases,cases))
            else:
                pygame.draw.rect(ecran,jaune, (cases*i,cases*j,cases,cases))

pygame.init()
ecran=pygame.display.set_mode((640,640))
damier()
continuer = True

while continuer :
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            continuer = False
    pygame.display.flip()
pygame.quit()

Programme pour mettre un ‘cavalier’ sur l’échiquier :

import pygame
import random
n,p=8,8
rouge=(255,0,0)
jaune=(240,200,0)
cases=80
echiquier=[[0]*n for i in range(p)]
X1=random.randint(0,n-1)
Y1=random.randint(0,p-1)

def damier():
    for i in range (8):
        for j in range (8):
            if (i+j)%2==1:
                pygame.draw.rect(ecran,rouge, (cases*i,cases*j,cases,cases))
            else:
                pygame.draw.rect(ecran,jaune, (cases*i,cases*j,cases,cases))

pygame.init()
ecran=pygame.display.set_mode((640,640))
image = pygame.image.load("ronald.jpg")
image1= pygame.transform.scale(image,(cases,cases))
damier()
ecran.blit(image1, (cases*X1, cases*Y1))
continuer = True

while continuer :
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            continuer = False
    pygame.display.flip()
pygame.quit()
