如何修复Pygame闪烁

时间:2019-01-14 23:23:34

标签: python python-3.x windows pygame flicker

所以,我决定尝试在pygame中制作一个应用程序,因为它比tkinter复杂得多(这也有助于我已经使用了其中的一部分),并且遇到了一个问题,即我的文本只有一部分在闪烁。 (并非屏幕上的所有文本只是其中的一部分)

一些环境信息:我正在Windows 10上在atom上运行python 3.7。我已经尝试隔离问题,但是无法找到问题的根源,我通过正常运行文件来检查它是否为原子,但这无济于事。

Python Tkinter refresh canvas

以下是对tkinter问题的答案,但与pygame问题的答案相似。我将引用它,因为它看起来更加简洁。

  

画布刷新的唯一方法是为事件循环提供“重绘”事件。在您的循环中,您永远不会给事件循环一个更新的机会,因此您看不到任何更改。

     

快速的解决方法是调用self.canvas.update_idletasks,但这只是黑客,而不是适当的解决方案。

     

制作动画的正确方法是使用事件循环进行迭代。通过将要完成的工作放在队列中(在本例中为空闲事件队列)来完成此操作。您可以使用after命令将内容放入此队列。

     

您应该做的是编写一个对动画进行一次迭代的函数。本质上,将所有内容放入while循环中并将其移至函数中。然后,安排有工作要做的地方连续调用该函数。您可以在该函数中调用after,也可以使用单独的函数来控制动画。
