Module 6 - Section 0 - Repeat!

If we want to animate an object that we are going to draw inside the main loop using the pygame template we should:

• First : create an initialization block of commands outside the Main program loop where we define the starting position (x , y) of the object and the starting speed in each axis:
   
  rect_x = 50    # X starting position of rectangle
  rect_y = 50    # Y starting position of rectangle
  speed_x = 5   # X speed of rectangle
  speed_y = 5   # Y speed of rectangle
  
  
• Second : inside the main loop change the position according to the speed:
  
  rect_x += speed_x
  rect_y += speed_y
  
  
• Third : Change the drawing command using the defined variables:
  
  pygame.draw.rect(screen, WHITE, [rect_x, rect_y, 50,50])
