05 Aug PMCA Sunday 14:00 Python Homework 21.08.01.

Question:
In the previous class we wrote the code to move the circle in left, right, up and down using the W-A-S-D keys.

Continue with the code, and try to also add the code to move the circle in left, right , up and down using the LEFT-RIGHT-UP-DOWN arrow keyboard keys.

Also, write code to change the color of the circle when you press the SPACE keyboard key.

The code from last week is below:

# Control the animation with our keys
# Move the circle by using W-A-S-D keys

# create a pygame window with a circle
# make sure you create the circle inside the while true loop
# create the variable circle_x, circle_y, speed_x and speed_y
import pygame, sys, random

pygame.init()

screen_height = 480
screen_width = 640
screen=pygame.display.set_mode([screen_width, screen_height])
screen.fill([150,222,232])
pygame.display.flip()

#create the variables
circle_x = 100
circle_y = 200
speed_x = 5
speed_y = 5
circle_radius = 50
clock = pygame.time.Clock()

while True:
	for event in pygame.event.get():
    	if event.type == pygame.QUIT:
        	pygame.quit()
        	sys.exit()
    	# this if statement will be true when the user
    	# pushes a key down on the keyboard
    	if event.type == pygame.KEYDOWN:
        	# if the key that is down is the w key
        	# than I will update the circle_y position so that it looks
        	# like the circle is moving up
        	if event.key == pygame.K_w:
            	    circle_y = circle_y - speed_y
           	 
        	# write condition to move the circle down when the s key is pressed

        	# write condition to move the circle left when the "a" key is pressed
        	# if statement will be true if the key that is pressed is "a"
        	if event.key == pygame.K_a:
            	    circle_x = circle_x - speed_x
        	# write condition to move the circle right when the "d" key is pressed

	# step 1 is clear the previous animation (fill the screen again )
	screen.fill([150,222,232])

	# last step is always to draw the circle at new position
	pygame.draw.circle(screen, [240,123,121], [circle_x,circle_y], circle_radius)

	pygame.display.flip()
	clock.tick(24)
