Racing Pygame Sample
First, pygame must be installed.
In CMD: pip install pygame
import pygame
pygame.init()
display_width = 800
display_height = 600
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('A bit Racey')
black = (0,0,0)
white = (255,255,255)
clock = pygame.time.Clock()
crashed = False
carImg = pygame.image.load('racecar.png')
def car(x,y):
gameDisplay.blit(carImg, (x,y))
x = (display_width * 0.45)
y = (display_height * 0.8)
while not crashed:
for event in pygame.event.get():
if event.type == pygame.QUIT:
crashed = True
gameDisplay.fill(white)
car(x,y)
pygame.display.update()
clock.tick(60)
pygame.quit()
quit()
Pygame Chest Open Sample
First, pygame must be installed.
In CMD: pip install pygame
import pygame
pygame.init()
pygame.display.set_caption('Crash!')
window = pygame.display.set_mode((300, 300))
running = True
# Draw Once
Rectplace = pygame.draw.rect(window, (255, 0, 0),(100, 100, 100, 100))
pygame.display.update()
# Main Loop
while running:
# Mouse position and button clicking.
pos = pygame.mouse.get_pos()
pressed1, pressed2, pressed3 = pygame.mouse.get_pressed()
# Check if the rect collided with the mouse pos
# and if the left mouse button was pressed.
if Rectplace.collidepoint(pos) and pressed1:
print("You have opened a chest!")
# Quit pygame.
for event in pygame.event.get():
