[英]TypeError: 'int' object has no attribute '__getitem__'
I'm trying to make a play surface out of rects in pygame. 我正在尝试使用pygame中的rects来制作游戏表面。 I'm not sure what the problem is exactly but I believe it has something to do with the actual iteration of the list when creating the rects.
我不确定问题到底出在哪里,但我相信这与创建rect时列表的实际迭代有关。 Sorry, noob here.
抱歉,这是菜鸟。 :)
:)
import pygame
w = 800
h = 600
board_pos = 0, 0
tile = 27
playfield = 0
class Board(object):
def __init__(self, surface, pos, tile_size):
self.surface = surface
self.x, self.y = pos
self.tsize = tile_size
self.color = 50, 50, 50
playfield = [list(None for i in xrange(22)) for i in xrange(10)]
def draw(self):
for i in xrange(10):
for j in xrange(22):
playfield[i][j] = pygame.draw.rect(self.surface, self.color,
(self.x + (i * self.tsize),
self.y + (j * self.tsize),
self.tsize, self.tsize))
pygame.display.init()
screen = pygame.display.set_mode((w, h))
board = Board(screen, board_pos, tile)
board.draw()
while __name__ == '__main__':
pygame.display.flip()
I keep getting this error: 我不断收到此错误:
Traceback (most recent call last):
File "C:\Documents and Settings\Administrator\My
Documents\Dropbox\Programming\DeathTris
\test2.py", line 30, in <module>
board.draw()
File "C:\Documents and Settings\Administrator\My
Documents\Dropbox\Programming\DeathTris
\test2.py", line 24, in draw
self.tsize, self.tsize))
TypeError: 'int' object has no attribute '__getitem__'
Any help would be appreciated. 任何帮助,将不胜感激。 Thanks!
谢谢!
Your line playfield = [list(None for i in xrange(22)) for i in xrange(10)]
creates a local variable inside the __init__
function. 您的行
playfield = [list(None for i in xrange(22)) for i in xrange(10)]
在__init__
函数内创建局部变量。 That variable disappears after the __init__
function returns. __init__
函数返回后,该变量消失。 Later in draw
when you do playfield[i][j]
, you are accessing the global value of playfield
, which is still 0 (since you initialized it to 0 at the beginning). 在
draw
稍后部分,当您执行playfield[i][j]
,您将访问playfield
的全局值,该值仍为0(因为在开始时将其初始化为0)。
If you want to overwrite the global playfield from inside your __init__
, you need to do global playfield
before you assign to it. 如果要从
__init__
内部覆盖全局运动场,则需要先执行global playfield
然后再分配给它。 (But. . . why are you using a global variable for this anyway?) (但是……为什么您仍然为此使用全局变量?)
