How to Get the Current State of a Key in Pygame?

Getting Key Press Status in Pygame

Unlike KEYDOWN and KEYUP methods that only capture press and release events respectively, obtaining the current state of a key in Pygame requires a different approach. To achieve this, leverage the pygame.key.get_pressed() function.

The pygame.key.get_pressed() function returns a list representing the current state of all possible keys. Each element in the list corresponds to a specific key and contains either True if the key is currently pressed or False if it's not.

To determine if a particular key is currently down, retrieve the state of the keys by calling pygame.key.get_pressed() within the main application loop. Subsequently, evaluate the state of the desired key by checking the corresponding element in the list. For instance, to check the state of the UP or DOWN key:

<code class="python">run = True
while run:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_UP]:
        # Code to handle key down
    if keys[pygame.K_DOWN]:
        # Code to handle key down</code>

Note that the key states are only updated when events are handled by pygame.event.pump() or pygame.event.get().
