Moving shapes

Assuming you have the pygame template from one of the other pages. We can move objects by using variable to specify the X & Y coordinate. The example below does this (when the code is running, the loop will need to clear the screen, create the object and then draw it):

<syntaxhighlight lang=python> <syntaxhighlight lang=python> COLOR = (255, 0, 200) BLACK = (0 , 0 , 0) X=100 # X coordinate for object Y=100 # Y coordinate for object

1. game loop

while True:

   SCREEN.fill(BLACK) # Clear screen
   rect1 = pygame.Rect([X,Y,20,20]) # create shape
   pygame.draw.rect(SCREEN, COLOR, rect1, 1) # draw shape
   pygame.display.update() # update screen

   #respond to player input ans change X & Y coordinates for next draw
   for events in pygame.event.get(): #get all pygame events
       if events.type == pygame.KEYDOWN:
           if events.key == pygame.K_LEFT:
               X=X-10
           elif events.key == pygame.K_RIGHT:
               X=X+10
           elif events.key == pygame.K_UP:
               Y=Y-10
           elif events.key == pygame.K_DOWN:
               Y=Y+10
       if events.type
