Question

我正在制作一个带有菜单的游戏，该菜单使用向左和向右箭头键进行导航。问题是，当您按下箭头之一时，它会在两个箭头之间快速切换。我假设我需要使用pygame.KEYUP，但是我不确定如何使用它。现在，它只是在“播放”和“退出”之间闪烁。这是我的代码。我想要它，所以如果您向左或向右按它可以选择播放或退出，并且不会在两者之间闪烁。

import pygame, time

def createWindow():
    global WIDTH, HEIGHT, TITLE, W
    WIDTH, HEIGHT = 800, 450
    TITLE = "Mega Maro Bois"
    pygame.display.set_caption(TITLE)
    W = pygame.display.set_mode( (WIDTH, HEIGHT), pygame.HWSURFACE|pygame.DOUBLEBUF )

createWindow()


menu = pygame.image.load("Graphics\\Menu.png")

play_sel = pygame.image.load("Graphics\\Play_Selected.png")
############################################################# QUIT PICTURES
quit = pygame.image.load("Graphics\\Quit.png")
quit_sel = pygame.image.load("Graphics\\Quit_Selected.png")


Event = "Menu"

loop = True

Button_Sel = "Play"
Button_Sel2 = 1


if Event == "Menu":
    W.blit(menu, (0, 0))
    W.blit(play, (25, 250))
    W.blit(quit, (435, 250))

while loop:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    if Event == "Menu":

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_1:
                Button_Sel = "Play"
            if event.key == pygame.K_2:
                Button_Sel = "Quit"
            if event.key == pygame.K_RIGHT:
                Button_Sel2 += 1
            if event.key == pygame.K_LEFT:
                Button_Sel2 -= 1


            #################################################################ENTER SELECT
            if Button_Sel == "Play" and event.key == pygame.K_RETURN:
                Event = "Play"
            if Button_Sel == "Quit" and event.key == pygame.K_RETURN:
                pygame.quit()
                exit()
            #################################################################SPACE SELECT
            if Button_Sel == "Play" and event.key == pygame.K_SPACE:
                Event = "Play"
            if Button_Sel == "Quit" and event.key == pygame.K_SPACE:
                pygame.quit()
                exit()                      


        ###################################################IF USER SELECTS PLAY
        if Button_Sel == "Play":
            W.blit(play_sel, (25, 250))
            W.blit(quit, (435, 250))
        ###################################################IF USER SELECTS QUIT
        if Button_Sel == "Quit":
            W.blit(play, (25, 250))
            W.blit(quit_sel, (435, 250))

        if Button_Sel2 == 1:
            Button_Sel = "Play"
        if Button_Sel2 == 2:
            Button_Sel = "Quit"


    pygame.display.update()

pygame.quit()
exit()

在这种情况下，我基本上只需要知道如何使用pygame.KEYUP。

Answer 1

您的if event.type == pygame.KEYDOWN:在事件处理循环for event in pygame.event.get():之外

这意味着您一遍又一遍地处理同一事件

将事件检查放入循环中。

我正在制作一个使用箭头键进行导航的菜单，但它不起作用
