How can I create custom events in Pygame?

You can create custom events in Pygame using the pygame.event module. First, define a new event type using pygame.USEREVENT + n, where n is a unique number.

Can you show me a code example?

Sure! Here's a simple example:

import pygame

# Initialize Pygame
pygame.init()

# Define a custom event
MY_EVENT = pygame.USEREVENT + 1

# Create a timer for the event
pygame.time.set_timer(MY_EVENT, 1000)  # Trigger every second

# Main loop
running = True
while running:
    for event in pygame.event.get():
        if event.type == MY_EVENT:
            print('Custom event triggered!')
        elif event.type == pygame.QUIT:
            running = False

pygame.quit()

What if I want to pass data with my custom event?

You can pass data by using the event object. For example:

# Create a custom event with data
custom_data = {'key': 'value'}
pygame.event.post(pygame.event.Event(MY_EVENT, custom_data))

# In the event loop, access the data like this:
if event.type == MY_EVENT:
    print(event.dict)  # This will print {'key': 'value'}
