Inefficiency of 'pygame.event.get()': Causes and Mitigation
In a Pygame environment, the utilization of multiple 'pygame.event.get()' loops can lead to missed or delayed events. This inefficiency arises from the queue-based nature of 'pygame.event.get()'. Each call to this function retrieves all queued events, effectively clearing the queue.
As illustrated in the code snippet provided, two 'for event in pygame.event.get()' loops are employed. However, this approach results in only one loop receiving the events while all subsequent loops encounter an empty queue. Consequently, events are missed or appear to be delayed.
To address this issue, it is crucial to acquire events only once per frame and then distribute them among multiple loops or functions. By adopting this approach, all loops and functions can access the same list of events.
Here's a modified code example that employs this more efficient event handling:
event_list = pygame.event.get() # 1st event loop for event in event_list: # Handle events # 2nd event loop for event in event_list: # Handle events # Function to handle events def handle_events(event_list): for event in event_list: # Handle events
