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)
