断断续续的在线 python 游戏
Choppy online python game
我使用 pygame 和套接字在 python 中编写了 Slither.io 的简单克隆，但我遇到了三个问题：
- 当我独自在笔记本电脑上玩游戏时，游戏时断时续。每隔十秒，我的游戏就会卡住一段时间（一毫秒），然后继续。这不是什么大问题，但很烦人。
- 当我在本地网络中的两台计算机上玩时，我看到另一台播放器（另一条蛇）也很不稳定。
- 最奇怪的问题是当我 运行 我的主笔记本电脑上的服务器然后 运行 我的第二台笔记本电脑上的游戏开始时，几秒钟后崩溃。客户端上的调试器说 pickle 数据在从服务器接收数据时被 t运行 处理。但是当我 运行 我的第二台笔记本电脑上的服务器程序和我的主笔记本电脑上的游戏时，一切都很好。为什么？
我试过了：
问题 1. 更改客户端上的 FPS 和服务器上的 time.sleep
问题 2. 在服务器
上更改 time.sleep
问题3.改变recv()方法的输入值

这是我在这里使用的 pygame_textinput 库。
您的第三个问题（被截断的 pickle 数据）是因为您使用的是 TCP，并且您正在对任何 recv returns 进行 unpickling。您可能会想，每当您 send 某事时，接收方调用 recv，return 就是完全相同的事情，但实际上并非如此。 TCP 将您的数据拆分成数据包，因此接收方可能不会同时接收到所有数据。
例如，如果您发送“abcdefgh”，然后单独发送“ijkl”，则允许第一个接收到 return“abcd”，第二个接收到 return“efghijkl”。或者第一个可以 return "ab"，第二个可以 return "cde"，第三个可以 return "fghijkl"，等等。
你必须设计一种方法让接收者知道什么时候停止接收。例如，如果您先发送“8abcdefgh”，然后发送“4ijkl”，接收方可能会收到“8abcdefgh4ij”，然后它知道“8abcdefgh”是一个“发送”（因为它以 8 字节开始，然后是 8 个字节）并且它知道“4ij”是下一个“发送”的开始，但它不是全部（因为它以 4 开头，但没有 4 个字节）。
另一种方法是在每条消息后发送一个特殊字符，如换行符（回车键）。这可能不适用于泡菜，因为泡菜中可以有换行符。但是你可以选择 pickles 没有的另一个字节，比如 0xFF。然后接收方知道继续接收直到它看到字节 0xFF。

这是我在这里使用的 pygame_textinput 库。
您的第三个问题（被截断的 pickle 数据）是因为您使用的是 TCP，并且您正在对任何 recv returns 进行 unpickling。您可能会想，每当您 send 某事时，接收方调用 recv，return 就是完全相同的事情，但实际上并非如此。 TCP 将您的数据拆分成数据包，因此接收方可能不会同时接收到所有数据。
例如，如果您发送“abcdefgh”，然后单独发送“ijkl”，则允许第一个接收到 return“abcd”，第二个接收到 return“efghijkl”。或者第一个可以 return "ab"，第二个可以 return "cde"，第三个可以 return "fghijkl"，等等。
你必须设计一种方法让接收者知道什么时候停止接收。例如，如果您先发送“8abcdefgh”，然后发送“4ijkl”，接收方可能会收到“8abcdefgh4ij”，然后它知道“8abcdefgh”是一个“发送”（因为它以 8 字节开始，然后是 8 个字节）并且它知道“4ij”是下一个“发送”的开始，但它不是全部（因为它以 4 开头，但没有 4 个字节）。
另一种方法是在每条消息后发送一个特殊字符，如换行符（回车键）。这可能不适用于泡菜，因为泡菜中可以有换行符。但是你可以选择 pickles 没有的另一个字节，比如 0xFF。然后接收方知道继续接收直到它看到字节 0xFF。
