self.rect 未找到? [英] self.rect not found?

问题描述

我有一个程序，它只是用来移动图像.我尝试将 self.rect 声明为 load_png() 调用的一部分，但它根本不喜欢它.我认为这会起作用的原因来自 http://www.pygame.org/docs/tut/tom/games6.html，说这应该可行:

I have a program that is simply made to move an image around. I try to state the self.rect as part of a load_png() call, but it simply does not like it. THe reason I think this will work is from http://www.pygame.org/docs/tut/tom/games6.html, saying that this should work:

def __init__(self, side):
            pygame.sprite.Sprite.__init__(self)
            self.image, self.rect = load_png('bat.png')
            screen = pygame.display.get_surface()
            self.area = screen.get_rect()
            self.side = side
            self.speed = 10
            self.state = "still"
            self.reinit()

这是我的代码，根据其自己网站上的 pygame 教程，它应该可以工作:

Here is my code, which according to the pygame tutorial from its own website, should work:

def _init_(self):
    pygame.sprite.Sprite._init_(self)
    self.state = 'still'
    self.image =  pygame.image.load('goodGuy.png')
    self.rect = self.image.get_rect()       
    screen = pygame.display.getSurface()

它给了我这个错误:

Traceback (most recent call last):
File "C:\Python25\RPG.py", line 37, in <module>
screen.blit(screen, Guy.rect, Guy.rect)
AttributeError: 'goodGuy' object has no attribute 'rect'

如果你们需要我所有的代码，评论吹，我会编辑它.

If you guys need all of my code, comment blew and I will edit it.

推荐答案

您没有定义 load_png 函数.

You don't have a load_png function defined.

您需要先创建 pygame 图像对象，然后才能访问其 rect 属性.

You need to create the pygame image object before you can access its rect property.

self.image = pygame.image.load(file)

然后您可以使用

self.rect = self.image.get_rect()

或者您可以根据您链接的示例创建 load_png 函数.

Or you could create the load_png function as per the example you linked.
