# Import a library of functions called 'pygame'
import pygame
 
# Initialize the game engine
pygame.init()
 
# Define some colors
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
BLUE = (0, 0, 255)
GREEN = (0, 255, 0)
RED = (255, 0, 0)
 
PI = 3.141592653
 
# Set the height and width of the screen
size = (400, 500)
screen = pygame.display.set_mode(size)
 
pygame.display.set_caption("Rotate Text")
 
# Loop until the user clicks the close button.
done = False
clock = pygame.time.Clock()
 
text_rotate_degrees = 0
 
# Loop as long as done == False
while not done:
 
for event in pygame.event.get(): # User did something
if event.type == pygame.QUIT: # If user clicked close
done = True # Flag that we are done so we exit this loop
 
# All drawing code happens after the for loop and but
# inside the main while not done loop.
 
# Clear the screen and set the screen background
screen.fill(WHITE)
 
# Draw some borders
pygame.draw.line(screen, BLACK, [100,50], [200, 50])
pygame.draw.line(screen, BLACK, [100,50], [100, 150])
 
# Select the font to use, size, bold, italics
font = pygame.font.SysFont('Calibri', 25, True, False)
 
# Sideways text
text = font.render("Sideways text", True, BLACK)
text = pygame.transform.rotate(text, 90)
screen.blit(text, [0, 0])
 
# Sideways text
text = font.render("Upside down text", True, BLACK)
text = pygame.transform.rotate(text, 180)
screen.blit(text, [30, 0])
 
# Flipped text
text = font.render("Flipped text", True, BLACK)
text = pygame.transform.flip(text, False, True)
screen.blit(text, [30, 20])
 
# Animated rotation
text = font.render("Rotating text", True, BLACK)
text = pygame.transform.rotate(text, text_rotate_degrees)
text_rotate_degrees += 1
screen.blit(text, [100, 50])
 
# Go ahead and update the screen with what we've drawn.
# This MUST happen after all the other drawing commands.
pygame.display.flip()
 
# This limits the while loop to a max of 60 times per second.
# Leave this out and we will use all CPU we can.
clock.tick(60)
 
# Be IDLE friendly
pygame.quit()
