Python Pygame

left, middle, right = pygame.mouse.get_pressed()

if left:

    print("Left Mouse Key is being pressed")

• The above code, as long as the mouse is being held down, it will keep printing

• Returns the coordinates of the mouse cursor on the screen

• The above code changes the type of cursor that appears on the screen

What does the following code do?

color = (random.randint(0,255), random.randint(0,255), random.randint(0,255))

• choose a random color

• fill the surface with random color

• change the background color according to the key pressed

How do I update the screen?

• import pygame

• pygame.init()

• surface = pygame.display.set_mode((400,300))

• pygame.display.flip()

Set image background

• bg1 = pygame.image.load("back1.jpg")

  surface.blit(bg1, (0, 0))

• bg1 = pygame.image.load("back1.jpg")

  surface = pygame.display.set_mode((800,500))

• bg1 = pygame.image.load("back1.jpg")

  pygame.display.set_caption("Animation")

What does the following code do?

if x >= 500: x = 0

        x += 3

    surface.fill((255, 255, 255))

      circle = pygame.draw.circle(surface, (0, 0, 255), (x, y), 15)

    pygame.display.update()

• move the circle to right

• create a surface

• set initial position of the circle

• check whether the circle pos. reached at the end

How do I import the pygame library?

• import pygame

• pygame.init()

• surface = pygame.display.set_mode((400,300))

• pygame.display.flip()

What is this function following the code?

event.button = 3

• pressing the left button

• pressing the right button

• scrolling forward

• scrolling back

How do I initialize the pygame?

• import pygame

• pygame.init()

• surface = pygame.display.set_mode((400,300))

• pygame.display.flip()

Draw a Rectangle

• surface = pygame.display.set_mode((400,300))

• pygame.draw.rect(surface, color, [30, 30, 60, 60])

• pygame.draw.line(surface, color, [20, 50], [180, 50], 3)

• pygame.draw.circle(surface, color, [300, 300], 200, 3)

How can I check for an event if a user has pushed any event in the queue?

• run = False

  for event in pygame.event.get():

  if event.type == pygame.QUIT:

  running = True

• run = True

  for event in pygame.event.get():

  if event.type == pygame.QUIT:

   running = False

• for event in pygame.event.pos():
