Question

我正试图在python中制作一个像蛇一样的游戏。我现在的问题是，我无法使用我的＆＃39;硬币列表中定义的值＆＃39;在我的for循环中。这是我执行时收到的错误：TypeError：＆＃39; int＆＃39;对象不可订阅。谢谢你的帮助。

for-loop for the coinlist:

          del coinlist[:1]
          snakelenght += 10

      uhr.tick(15)
mainloop()

pygame.quit()
quit()

Answer 1

你正在追加筹码列表（rx和ry是从10到790/590的随机整数），之后你试图访问coinlist中的元素，就好像它们是数组一样。

考虑做一些事情，比如替换

coinlist.append(rx)
coinlist.append(ry)

与

coinlist.append([rx,ry])

从列表中获取int（pygame）
