按住python pygame鍵

Question

我試圖使飛機在按住向下鍵時保持向左移動，我正在使用pygame.key.get_pressed（），但僅響應一次，就像正常的pygame.KEYDOWN僅打印一次“向右移動”

有人可以幫忙嗎？

def key_control(hero_temp):
    for event in pygame.event.get():

        if event.type == pygame.QUIT:
        print('Game Exit')
        exit()

        key_state = pygame.key.get_pressed()
        if key_state[pygame.K_RIGHT]:
            print('move to right')
            hero_temp.x += 10
        if key_state[pygame.K_LEFT]:
            print('move to left')
            hero_temp.x -= 10
        if key_state[pygame.K_UP]:
            print('move to top')
            hero_temp.y -= 10
        if key_state[pygame.K_DOWN]:
            print('move to right')
            hero_temp.y += 10
        if key_state[pygame.K_SPACE]:
            print('space/shoot')
            hero_temp.fire()

Answer 1

您僅在循環訪問每個事件的循環內調用key_state = pygame.key.get_pressed() 。 只需將其從那里拿出來，它應該可以工作。

問題在於，如果有新事件，它將僅檢查按下的按鈕。 如果沒有新事件，則不會檢查按下的按鈕，也不會執行代碼

def key_control(hero_temp):
    key_state = pygame.key.get_pressed()
    if key_state[pygame.K_RIGHT]:
        print('move to right')
        hero_temp.x += 10
    if key_state[pygame.K_LEFT]:
        print('move to left')
        hero_temp.x -= 10
    if key_state[pygame.K_UP]:
        print('move to top')
        hero_temp.y -= 10
    if key_state[pygame.K_DOWN]:
        print('move to right')
        hero_temp.y += 10
    if key_state[pygame.K_SPACE]:
        print('space/shoot')
        hero_temp.fire()

    for event in pygame.event.get():
        # Only gets run if there are new events
        if event.type == pygame.QUIT:
            print('Game Exit')
            exit()

        if event.type == pygame.QUIT:
            print('Game Exit')
