尝试在类中绘制pygame精灵但出现错误

Question

我试图在类中的 pygame 中绘制精灵，但是出现错误。

这是我的代码：

import pygame

# Initiate Pygame
pygame.init()

# Set The Screen Size
screen = pygame.display.set_mode([800, 600])

# Set The Window Title & Icon
pygame.display.set_caption("Pacman")



# Player
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("Pacman_Player.tiff").convert
        self.rect = self.image.get_rect()
        self.draw = screen.blit(self.rect, 200, 200)
    


# Background Image

backImg_1 = pygame.image.load("maze.png").convert()
backImg = pygame.transform.scale(backImg_1, (800, 600))

# Game Loop
running = True

while running:
    # Player
    Player = Player()
    
    # Background Image
    screen.blit(backImg, (0, 0))
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()

    

这是我尝试运行此代码时收到的错误消息：

  File "/Users/nagz/Pacman/Pacman.py", line 34, in <module>
    Player = Player()
  File "/Users/nagz/Pacman/Pacman.py", line 19, in __init__
    self.rect = self.image.get_rect()
AttributeError: 'builtin_function_or_method' object has no attribute 'get_rect'

错误消息说 pygame 中没有

get_rect

方法，但是 pygame 中有一个

get_rect

方法。

Answer 1

您需要在

处调用

Surface.convert()

函数

self.image = pygame.image.load("Pacman_Player.tiff").convert

成为

self.image = pygame.image.load("Pacman_Player.tiff").convert()

请参阅文档

Surface.convert()

。

对于新错误（由OP在评论中提供），

File "/Users/nagz/Pacman/Pacman.py", line 34, in <module>
     Player = Player()   File "/Users/nagz/Pacman/Pacman.py", line 20, in __init__
     self.draw = screen.blit(self.rect, 200, 200) 
TypeError: argument 1 must be pygame.Surface, not pygame.Rect

只需更换

screen.blit(self.rect, 200, 200)

与

color = 255, 0, 0
pygame.draw.rect(screen, color 200, 200, self.rect.w, self.rect.h)

Answer 2

import pygame

# Initiate Pygame
pygame.init()

# Set The Screen Size
screen = pygame.display.set_mode([800, 600])

# Set The Window Title & Icon
pygame.display.set_caption("Pacman")



# Player
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("Pacman_Player.tiff").convert()
        self.rect = self.image.get_rect()
        self.draw = screen.blit(self.rect, 200, 200)
    


# Background Image

backImg_1 = pygame.image.load("maze.png").convert()
backImg = pygame.transform.scale(backImg_1, (800, 600))

# Game Loop
running = True

while running:
    # Player
    Player = Player()
    
    # Background Image
    screen.blit(backImg, (0, 0))
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()

Answer 3

您在

()

之后缺少

convert

，请将其更改为：

self.image = pygame.image.load("Pacman_Player.tiff").convert()

并更改：

self.draw = screen.blit(self.rect, 200, 200)

到

self.draw = lambda: screen.blit(self.image, (200, 200))

这样，每当你想绘制精灵时，你都可以调用

self.draw()

。

代码如下：

import pygame

# Initiate Pygame
pygame.init()

# Set The Screen Size
screen = pygame.display.set_mode([800, 600])

# Set The Window Title & Icon
pygame.display.set_caption("Pacman")



# Player
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = pygame.image.load("Pacman_Player.tiff").convert()
        self.rect = self.image.get_rect()
        self.draw = lambda: screen.blit(self.image, (200,200))
    


# Background Image

backImg_1 = pygame.image.load("maze.png").convert()
backImg = pygame.transform.scale(backImg_1, (800, 600))

# Game Loop
running = True

while running:
    # Player
    Player = Player()
    
    # Background Image
    screen.blit(backImg, (0, 0))
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()
