How to Avoid Blocking and Run Multiple Loops Simultaneously in Pygame?

How to Run Multiple While Loops Simultaneously in Pygame

In Pygame applications, it's crucial to avoid the use of blocking functions like time.sleep() to perform delays. Instead, rely on the application loop and functions like pygame.time.get_ticks() to manage time-related tasks.

Understanding the Challenge

In the code provided in the query, multiple while loops attempt to run concurrently, but one loop using time.sleep() blocks the other from executing.

The Solution: Using Pygame Time Functions

To correctly handle time delays, use pygame.time.get_ticks() to获取时间戳。 Calculate when to perform specific actions based on the current time. When the current time exceeds the calculated time, execute the action.

Revised Code:

In this code, the next_render_time variable stores the time at which the face should be updated. When the current time exceeds this value, a new face is randomly selected, rendered, and displayed. This approach allows multiple loops to run simultaneously without blocking.
