当我们在终端 python 中输入时，如何在 window 中保持 运行 游戏
How to keep run a game in window while we are inputting in terminal python
我是 python 编程新手 我正在编写蛇游戏代码，其中蛇在 x 轴上随机移动。并且用户必须在终端中输入 x 轴上食物和毒药的位置。而且蛇一定是在食物和毒药里面。
"The main thing i want to that is while the user input any location of food and Poison the snake must move whole time without stopping"
如果您能提供一些可以帮助我或对下面给出的代码进行一些更改的东西，我将不胜感激
谢谢

如果您只想简单地执行此操作，我会读取文本文件而不是从控制台读取。如果读取的新值与先前读取的值不同，则假设它们已被更改。
类似于：
food_x = -1
food_y = -1
... # in main loop
try:
# try to read the content of "user_input.txt", which we expect to be two numbers
user_input = open( 'user_input.txt', 'rt' ).read()
user_input = user_input.split( ' ' ) # split input into words
user_input = list( filter( None, user_input ) ) # throw away any empty strings
new_food_x = int( user_input[0] )
new_food_y = int( user_input[1] )
# We read 2 integers from the file
# but are they different to last time?
if ( new_food_x >= 0 and new_food_y >= 0 and
new_food_x != food_x and new_food_y != food_y ):
food_x = new_food_x
food_y = new_food_y
# TODO: whatever else is needed to flag a new food item
except:
pass # file not found, typos, not numbers, etc. ignore any/all errors
另一种方法是在线程中从控制台读取，并使用 PyGame 事件 post 将结果返回到主 GUI 线程。这涉及更多。我以为我以前回答过这个问题，但我找不到...所以也许没有。
下面是一些示例代码，它在线程中读取 stdin，将事件发回主线程。此示例读取数字或单词 "quit".
