How Can I Handle Keyboard Input in Pygame to Avoid Excessively Fast Movement?

Getting User Input in Pygame: Keyboard Input

In Pygame, controlling game objects with the keyboard involves obtaining input on key events. While pygame.key.get_pressed() provides information on currently pressed keys, it can lead to issues with rapid object movement when keys are held down.

Resolving Fast Ship Movement

To ensure the ship only moves once per key press, use pygame.event.get() to detect the pygame.KEYDOWN event. This event occurs when a key is initially pressed, allowing for more precise control.

events = pygame.event.get()
for event in events:
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            # Handle left arrow key press
        if event.key == pygame.K_RIGHT:
            # Handle right arrow key press

Continuous Movement

To allow continuous movement while a key is held down, implement a counter or a maximum frame rate to limit movement. For example, using a counter:

move_ticker = 0
keys = pygame.key.get_pressed()
if keys[K_LEFT]:
    if move_ticker == 0:
        move_ticker = 10  # Set move limit to 10 frames
        # Move left
if keys[K_RIGHT]:
    if move_ticker == 0:
        move_ticker = 10  # Set move limit to 10 frames
        # Move right

In your game loop, update the counter as necessary:

if move_ticker > 0:
    move_ticker -= 1

This solution restricts movement to once every 10 frames, preventing excessively rapid movement.
