Question

Python 2.7

我试图在pygame中创建一个类似钢琴的东西，当按下一个键时，会弹奏一个音符。我的问题是，当按键被按下时，我无法弄清楚如何让音符永远播放。我试着做一个while循环，但我无法弄清楚如何离开它。

import pygame

pygame.mixer.pre_init(44100, -16, 2, 2048)
pygame.init()
size = width, height = 800, 400
screen = pygame.display.set_mode((size))

while 1:
    for event in pygame.event.get():
            if event.type == pygame.QUIT:
                exit()
            if event.type == pygame.KEYDOWN:
                if event.type == pygame.KEYUP:
                    break
                elif event.key == pygame.K_i:
                    pygame.mixer.music.load('file.wav') #A
                    pygame.mixer.music.play()

                elif event.key == pygame.K_o:
                    pygame.mixer.Sound('file.wav').play() #B

                elif event.key == pygame.K_e:
                    pygame.mixer.Sound('file.wav').play() #C

                elif event.key == pygame.K_r:
                    pygame.mixer.Sound('file.wav').play() #D

                elif event.key == pygame.K_t:
                    pygame.mixer.Sound('file.wav').play() #E

                elif event.key == pygame.K_y:
                    pygame.mixer.Sound('file.wav').play() #F

                elif event.key == pygame.K_u:
                    pygame.mixer.Sound('file.wav').play() #G

Answer 1

while running:
    keys = pygame.key.get_pressed()  #checking pressed keys
    if keys[pygame.K_UP]:
       pygame.mixer.Sound('file.wav').stop()
    if keys[pygame.K_DOWN]:
       pygame.mixer.Sound('file.wav').play()

当按下某个键时，它将继续播放该键，但当它不再被按下时它将停止。

你如何在Pygame中连续演奏音符？
