Issue with pygame.transform.rotate(), Index is apparently out of range - python-3.x

Question

So I am working on a basic PacMan game, and am trying to get my player to run through its sprite_sheet to show an animation. It works flawlessly when I am moving it right (thats the original orientation of the image), however for any of the other directions where I pygame.transform.rotate() the image, it returns the following:
self.image = (PAC_UP[self.spritesheet_index % 4])
IndexError: list index out of range
Not sure why this is happening (clearly it has to do with rotation). Any explanation on rotations and why this is happening would be greatly appreciated!
Thanks!
Heres my code:
class sprite_sheet():
def __init__ (self, filename):
self.spritesheet = pygame.image.load(filename)
def get_image(self, x, y, width, height):
image = pygame.Surface((width, height))
image.set_colorkey(BLACK)
image.blit(self.spritesheet, (0,0), (x, y, width, height))
return image
PAC_RIGHT = []
for x in range(4):
image = (sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24))
PAC_RIGHT.append(image)
PAC_UP = []
for x in range(4):
image = sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24)
PAC_RIGHT.append(pygame.transform.rotate(image, 90))
PAC_LEFT = []
for x in range(4):
image = sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24)
PAC_RIGHT.append(pygame.transform.rotate(image, 180))
PAC_DOWN = []
for x in range(4):
image = sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24)
PAC_RIGHT.append(pygame.transform.rotate(image, 270))
class Player (pygame.sprite.Sprite):
def __init__(self, game, x, y):
self.groups = game.all_sprites
pygame.sprite.Sprite.__init__(self, self.groups)
self.game = game
self.image = sprite_sheet('pacman-spritesheet.png').get_image(0, 0, 24, 24)
self.x = x * TILESIZE
self.y = y * TILESIZE
self.rect = self.image.get_rect()
self.vx, self.vy = 0, 0
self.spritesheet_index = 0
self.first_time = pygame.time.get_ticks()
self.delay = 43
def get_keys(self):
self.vx, self.vy = 0, 0
keys = pygame.key.get_pressed()
self.spritesheet_index += 1
if keys[pygame.K_LEFT]:
self.vx = -PLAYER_SPEED
self.second_time = pygame.time.get_ticks()
if self.second_time-self.first_time > self.delay:
self.image = (PAC_LEFT[self.spritesheet_index % 4])
self.first_time = pygame.time.get_ticks()
if keys[pygame.K_RIGHT]:
self.vx = PLAYER_SPEED
self.second_time = pygame.time.get_ticks()
if self.second_time-self.first_time > self.delay:
self.image = (PAC_RIGHT[self.spritesheet_index % 4])
self.first_time = pygame.time.get_ticks()
if keys[pygame.K_UP]:
self.vy = -PLAYER_SPEED
self.second_time = pygame.time.get_ticks()
if self.second_time-self.first_time > self.delay:
self.image = (PAC_UP[self.spritesheet_index % 4])
self.first_time = pygame.time.get_ticks()
if keys[pygame.K_DOWN]:
self.vy = PLAYER_SPEED
self.second_time = pygame.time.get_ticks()
if self.second_time - self.first_time > self.delay:
self.image = (PAC_DOWN[self.spritesheet_index % 4])
self.first_time = pygame.time.get_ticks()

Looks like you're only adding your sprite images to the PAC_UP list:
PAC_RIGHT = []
for x in range(4):
image = (sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24))
PAC_RIGHT.append(image)
PAC_UP = []
for x in range(4):
image = sprite_sheet('pacman-spritesheet.png').get_image(x*24, 0, 24, 24)
PAC_RIGHT.append(pygame.transform.rotate(image, 90))
Modify your code to append to the appropriate lists, PAC_DOWN, PAC_LEFT & PAC_RIGHT.
Additionally, this looks to be a copy-paste error. Instead of copy-pasting, it would be better to create a function to do your image loading.
Here's an untested example:
def load_sprite_images(rotation, filename='pacman-spritesheet.png'):
"""Load four sprite images from the specified file"""
images = []
for x in range(4):
image = (sprite_sheet(filename).get_image(x*24, 0, 24, 24))
images.append(pygame.transform.rotate(image, rotation))
return images
PAC_RIGHT = load_sprite_images(0)
PAC_UP = load_sprite_images(90)
PAC_LEFT = load_sprite_images(180)
PAC_RIGHT = load_sprite_images(270)
