I'm trying to animate a sprite using a loop such that each time the loop runs through the position number for an image in an array increases by one. I keep getting "UnboundLocalError: local variable 'Antic' referenced before assignment". There is

    Antic = 0

Antic = int(Antic)

# Global constants

StAnmtn = ["Images/PlayerVampireStanding1.png", " 

Images/PlayerVampireStanding2.png", 

"Images/PlayerVampireStanding3.png","Images/PlayerVampireStanding4.png", 

"Images/PlayerVampireStanding5.png", "Images/PlayerVampireStanding6.png", 

"Images/PlayerVampireStanding7.png", "Images/PlayerVampireStanding8.png"]

`
at the start and

    def main():

    """ Main Program """

    pygame.init()



    clock = pygame.time.Clock()     # creates clock to limit frames per 

    second



    FPS = 60  # sets max speed of min loop



    SCREENSIZE = SCREENWIDTH, SCREENHEIGHT = 1300, 700  # sets size of 

    screen/window

    screen = pygame.display.set_mode(SCREENSIZE)  # creates window and game 

    screen



    pygame.display.set_caption("Count Acheron")



    # Create the player

    player = Player()



    # Create all the levels

    level_list = 

    level_list.append( Level_01(player) )



    # Set the current level

    current_level_no = 0

    current_level = level_list[current_level_no]



    active_sprite_list = pygame.sprite.Group()

    player.level = current_level



    player.rect.x = 340

    player.rect.y = SCREEN_HEIGHT - player.rect.height

    active_sprite_list.add(player)



    # Loop until the user clicks the close button.

    done = False



    # Used to manage how fast the screen updates

    clock = pygame.time.Clock()



    # -------- Main Program Loop -----------

    while not done:



        for event in pygame.event.get():

            if event.type == pygame.QUIT:

                done = True



            if event.type == pygame.KEYDOWN:

                if event.key == pygame.K_LEFT:

                    player.go_left()

                if event.key == pygame.K_RIGHT:

                    player.go_right()

                if event.key == pygame.K_UP:

                    player.jump()



            if event.type == pygame.KEYUP:

                if event.key == pygame.K_LEFT and player.change_x < 0:

                    player.stop()

                if event.key == pygame.K_RIGHT and player.change_x > 0:

                    player.stop()  



        if Antic > 6:

            Antic = 0

        else:

            Antic += 1

        # Update the player.

        active_sprite_list.update()



        # Update items in the level

        current_level.update()



        # ALL CODE TO DRAW SHOULD GO BELOW THIS COMMENT

        current_level.draw(screen)

        active_sprite_list.draw(screen)



        # ALL CODE TO DRAW SHOULD GO ABOVE THIS COMMENT



        # Limit to 60 frames per second

        clock.tick(60)



        # Go ahead and update the screen with what we've drawn.

        pygame.display.flip()

        # Be IDLE friendly. If you forget this line, the program will 'hang'

        # on exit.

        pygame.quit()



    if __name__ == "__main__":

        main()

as the loop. What it doesn't seem to like is the snippet of code

    if Antic > 6:

        Antic = 0

    else:

        Antic += 1

How do I fix this?

Personally I've never used pygame's sprite module.

import pygame



class character:

    def __init__(self, x, y):

        self.x = x

        self.y = y

        self.sprites = [pygame.image.load("img1.png"), pygame.image.load("img2.png")]

        self.frame = 0



    def draw(self, surface):

        surface.blit(self.sprites[self.frame], (self.x, self.y))

        self.frame += 1

        if self.frame > len(self.sprites) - 1: self.frame = 0



pygame.init()

DS = pygame.display.set_mode((1280, 720))

clock = pygame.time.Clock()



c = character(640, 360)



while True:

    for event in pygame.event.get():

        if event.type == pygame.QUIT or (event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE):

            pygame.quit()



    c.draw(DS)

    pygame.display.update()

    clock.tick(30)

    DS.fill((0, 0, 0))

Needed to globalise the function ("global Antic" in the main loop)
