出现包含 GLUT 图形的窗口后,我想在终端中输入:
user@computer: python woop.py
# Now displaying a beautiful landscape
(cmd): season winter
# Now changing season to winter
(cmd): event meteor
# Now meteoring otherwise peaceful landscape
(cmd): season summer
# Now changing season to summer
(cmd): exit
#bye ^_^
user@computer:
理想情况下,我想将 python cmd与 GLUT 的glutKeyboardFunc 集成。我的尝试失败了(一次允许一个或另一个,而不是两者。还有窗口或终端是否有焦点的问题)。
这是一些示例代码,它显示了一个旋转的茶壶。目前,按下“m”将调用流星善良(存根),但能够输入例如“meteor 500”将是更可取的。
#! /usr/bin/env python

我可以使用glutKeyboardFunc将字符收集到一个全局字符串中,提供相同的功能效果,但是用户会盲目输入。“print somestring”允许在同一行打印,但是逗号表示在键入时不会显示输出。“print '\b'”(退格)也不能普遍工作......
基本上我不想拥有:
user@computer: python woop.py
# Now displaying a beautiful landscape
(cmd): s
(cmd): se
(cmd): sea
(cmd): seas
...etc
输入一个命令
使用限制:
- pyopengl
- 过剩
(尽管对于希望解决不同问题的任性未来的人们欢迎其他答案)
