# @@@ change the name of makeMyDrawingPoints to have an appropriate name like
#   makeMySurfboardPoints, or makeMyChristmasTreePoints, etc.

# makeMyDrawingPoints   make a tuple of points for my drawing
#    @@@ put an explanation here of what you are trying to draw
#
# consumes:
#     x, y  (numbers: @@@ describe where this point is--bottom left? bottom right? bottom center? top center?
#     height, width  (@@@ you might need only one of these, or you might need both)
# produces
#     what does it produce? a tuple or a list of points?
#     a tuple is some values in () separated by commas (see drawSnowManWithTests.py for an example)
#     a list of points looks like this: [(x,y), (x,y+height), (x+0.5*width, y)]
#        (see drawHousesWithTests.py for examples)

def makeMyDrawingPoints(x,y,width,height):

    # @@@ Add some assignment statements here that compute the various parts of your drawing
    
    
    return -1 # replace this with the tuple or the list you are returning


# @@@ PUT TWO TEST CASES HERE   (or at least one... one is better than zero, but won't get full credit)



# @@@ rename "drawMyDrawing" to something like "drawSurfboard" or "drawChristmasTree" as needed.

# drawMyDrawing -- a function to draw a "@@@ my drawing" with PyGame
# consumes:
#     x, y  (numbers: @@@ describe again where this is)
#     height,width  (numbers: width,height @@@ do you need both?)
#     screen (the screen where we should draw this house)
#     color (a tuple of (r, g, b) representing a color)
# produces
#     nothing
# side effect
#     draws (@@@ my drawing) on the screen of the size and color given,
#     at the location given
                  
def drawMyDrawing(x,y,width,height,screen,color):
    lineThickness = 3

    # if applicable...
    # calculate all the points, and unpack them from the tuple into individual variables
    #   e.g. (botX,botY,botR,midX,midY,midR,topX,topY,topR) = makeSnowmanPoints(x,y,height)

 
    # Now draw the circles (putting int around the points and radius), or
    #  draw the lines (calling the function that pulls in the list of points)
    

    
# draw()  a function to actually do the drawing
#  consumes and produces nothing
#  side effect: we see a window with our drawing
#  to call this function, type draw() in the Python Shell after you do "Run Module" in IDLE

def draw():
    
    # set up a window (a.k.a. a screen)

    size = width, height = 640,480
    pygame.init()
    screen = pygame.display.set_mode(size)

    # set up variables for colors (add more colors here if you like)

    red = (255, 0, 0 )  # an RGB 3-tuple representing red
    green = (0, 255, 0)
    white = (255, 255, 255)
    blue = (0, 0, 255)

    # main loop

    while True: # loop forever (or at least until someone generates a QUIT event)

        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit(); exit()

        screen.fill(white); # Make the whole screen white (you could change this to some other color)

        # @@@@ Now, draw my Drawing (at least three times in different places)
        # e.g. three different calls to drawSnowman(100,200,90,screen,red)
        # or  drawHouse(100,200,120,150,screen,red) with different parameters.





        # But, we don't actually SEE anything until we call "update".
