Order class objects are displayed on the screen - pygame

Question

I am very new to Python and Pygame, if anyone can help point me in the right direction I would really appreciate it :)
From what I understand, the order these are displayed determines how they will appear.
I need the "ticker" to appear in front of the other class object, "tickerchart" but I can't seem to figure out why it isn't working.
self.ticker_movement() is first on the list.
Can anyone tell me why the ticker is not showing up on top of the "tickerchart" image when it moves to the same space on the screen?
class Ticker:
def __init__(self, main_ticker_screen):
self.main_ticker_screen = main_ticker_screen
TICKER_IMAGE = pygame.image.load(r'C:\Desktop\Coding\PYTHON\EXPERIMENT\assets\ticker.png').convert_alpha()
self.TICKER = pygame.transform.scale(TICKER_IMAGE, (6, 95))
self.TICKER_x = 1277.5
self.TICKER_y = 841
self.TICKER_direction = 'none'
def move_right(self):
self.TICKER_direction = 'right'
def move_left(self):
self.TICKER_direction = 'left'
def stopmoving(self):
self.TICKER_direction = 'none'
def drawticker(self):
self.main_ticker_screen.fill(BLACK)
self.main_ticker_screen.blit(self.TICKER, (self.TICKER_x, self.TICKER_y))
pygame.display.flip()
def movement(self):
if self.TICKER_direction == 'right':
self.TICKER_x += 22
if self.TICKER_direction == 'left':
self.TICKER_x -= 22
if self.TICKER_direction == 'none':
self.TICKER_x = self.TICKER_x
self.drawticker()
class TickerChart:
def __init__(self, ticker_screen):
self.ticker_screen = ticker_screen
FORTY_ONE_LEFT_IMAGE = pygame.image.load(r'C:\Desktop\Coding\PYTHON\EXPERIMENT\assets\41.png').convert_alpha()
self.FORTY_ONE = pygame.transform.scale(FORTY_ONE_IMAGE, (6, 120))
def draw_tickerchart(self):
#greytickers #left - 40s
self.ticker_screen.blit(self.FORTY_ONE, (1079.5, 816))
pygame.display.flip()
class Game:
def __init__(self):
pygame.init()
self.surface = pygame.display.set_mode((2555, 1005))
pygame.display.set_caption("PBF SCORE")
self.surface.fill(BLACK)
SCOREBOARD_IMAGE = pygame.image.load(r'C:\Desktop\Coding\PYTHON\EXPERIMENT\assets\score_board.png').convert_alpha()
self.SCOREBOARD = pygame.transform.scale(SCOREBOARD_IMAGE, (1236, 700))
self.surface.blit(self.SCOREBOARD, (650, 0))
self.ticker = Ticker(self.surface)
self.ticker.drawticker()
self.tickerchart = TickerChart(self.surface)
self.tickerchart.draw_tickerchart()
def run(self):
running = True
while running:
for event in pygame.event.get():
if event.type == KEYDOWN:
if event.key == K_ESCAPE:
running = False
if event.key == K_q:
self.ticker.move_right()
if event.key == K_o:
self.ticker.move_left()
if event.key == K_p:
self.ticker.stopmoving()
elif event.type == QUIT:
running = False
self.ticker.movement()
self.surface.blit(self.SCOREBOARD, (650, 0))
self.tickerchart.draw_tickerchart()
time.sleep(0.65)
if __name__ == "__main__":
game = Game()
game.run()

Answer 1

A possible problem might be that you arent calling for Ticket to be drawn every frame, only them the Game() class is initialized.
Put this in the run loop:
class Game:
def __init__(self):
pygame.init()
self.surface = pygame.display.set_mode((2555, 1005))
pygame.display.set_caption("PBF SCORE")
self.surface.fill(BLACK)
SCOREBOARD_IMAGE = pygame.image.load(r'C:\Desktop\Coding\PYTHON\EXPERIMENT\assets\score_board.png').convert_alpha()
self.SCOREBOARD = pygame.transform.scale(SCOREBOARD_IMAGE, (1236, 700))
self.surface.blit(self.SCOREBOARD, (650, 0))
self.ticker = Ticker(self.surface)
self.ticker.drawticker()
self.tickerchart = TickerChart(self.surface)
self.tickerchart.draw_tickerchart()
def run(self):
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_ESCAPE:
running = False
if event.key == pygame.K_q:
self.ticker.move_right()
if event.key == pygame.K_o:
self.ticker.move_left()
if event.key == pygame.K_p:
self.ticker.stopmoving()
elif event.type == pygame.QUIT:
running = False
self.ticker.movement()
self.surface.blit(self.SCOREBOARD, (650, 0))
self.tickerchart.draw_tickerchart() # just add this line!!
time.sleep(0.65)
if __name__ == "__main__":
game = Game()
game.run()
I ran this and it seemed to work fine, the ticker (the moving object i presume) does apear and it does move around.
You just need to change ONE line of code in the Game class.
