Problem with pygame.event.clear

[patriciainman]

Hello, instead of immediately processing key events as they occur, I think you can queue them and process them one at a time. This ensures that only one key event is processed before moving on to the next trial. You can use a list or a queue to store the key events and process them sequentially.

Here's an example of how you can modify your code to implement event queuing:

python
event_queue = []  # Create an empty event queue

# Inside the event loop
for event in pygame.event.get():
    if event.type == pygame.KEYDOWN:
        event_queue.append(event)  # Add key events to the queue

# Process the key events one by one
for event in event_queue:
    if event.key == pygame.K_LEFT:
        # Process left key event
    elif event.key == pygame.K_RIGHT:
        # Process right key event
    elif event.key == pygame.K_ESCAPE:
        # Process escape key event

event_queue.clear()  # Clear the event queue after processing
```

This way, only the events in the queue will be processed, and any other key events that occurred during the trial will be ignored.
