你好。我好像没有遇到错误，但是它不能正常工作。重点是c1，c2和c3不想工作。当我将鼠标悬停在它们上方（c1，， ）时c2，c3它告诉我：“局部变量值未被使用”（我在 PyCharm 中编码）。
理论上c1，c2这些c3都是细胞，细胞。当其中任意一个取值为 时True，表示该单元格已被占用，但直到顶部第一个单元格未被占用（c1），其余单元格才能取值True。
bg它是一个 9x9 单元格区域。当然，这些并不是全部的单元格，只是代码被缩短了。但是这些单元格（c1，c2，c3）在左行垂直排列。细胞数量为何这么少？嗯...我就是需要这样的。
我在论坛中搜索我的问题的答案，但没有找到答案或答案不合适。要么我瞎了。
以下是代码：
import pygame
from random import randint
from pygame import KEYDOWN, K_SPACE
w = 1280
h = 720
s_size = w, h
pygame.init()
screen = pygame.display.set_mode(s_size)
pygame.display.set_caption("First steps")
bg = pygame.image.load("images/KBGameFINAL.png")
bg = pygame.transform.scale(bg, s_size)
whb = (72, 72)
bone1 = pygame.image.load("images/KBG1.png")
bone1 = pygame.transform.scale(bone1, whb)
bone2 = pygame.image.load("images/KBG2.png")
bone2 = pygame.transform.scale(bone2, whb)
screen.blit(bg, (0, 0))
running = True
button_surface1 = pygame.Surface((72, 248))
button_rect1 = pygame.Rect(512, 408, 72, 248)
block = False
b = None
y = 408
y2 = 496
y3 = 584
cell1 = False
cell2 = False
cell3 = False
def check(x, bo, c1, c2, c3): # Здесь проблема!
global block
if c3: pass
elif c2:
screen.blit(bo, (x, y3))
c3 = True #Local variable 'c3' value is not used
block = True
elif c1:
screen.blit(bo, (x, y2))
c2 = True #Local variable 'c2' value is not used
block = True
else:
screen.blit(bo, (x, y))
c1 = True #Local variable 'c1' value is not used
block = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
if button_rect1.collidepoint(event.pos):
if block:
continue
if b == bone1:
check(512, bone1, cell1, cell2, cell3)
elif b == bone2:
check(512, bone2, cell1, cell2, cell3)
elif event.type == KEYDOWN:
if event.key == K_SPACE:
bxy1 = (216, 496)
n = randint(1, 2)
if n == 1:
screen.blit(bone1, bxy1)
b = bone1
elif n == 2:
screen.blit(bone2, bxy1)
b = bone2
pygame.display.update()
pygame.quit()
好啦，就这样。我希望得到你的帮助。
