标签： python click pygame

我正在尝试使用python 2.7和pygame进行游戏/测验，我希望用户单击具有正确答案的按钮。我做了一个按钮功能，检查鼠标是否在按钮内并继续执行操作。问题是当我点击开始后运行程序时，它会显示第二个屏幕而不是第一个屏幕。

import pygame

pygame.init()

display_width = 900
display_height = 600

black = (0,0,0)
white = (255,255,255)

bright_red =(200,0,0)
bright_green = (0,200,0)

gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption("A MATH'S GAME")


def button(msg,x,y,w,h,ic,ac,action=None):
    mouse = pygame.mouse.get_pos()
    click = pygame.mouse.get_pressed()
    if x+w > mouse[0] > x and y+h > mouse[1] > y:
        pygame.draw.rect(gameDisplay, ac,(x,y,w,h))

        if click[0] == 1 and action != None:
            action()         
    else:
        pygame.draw.rect(gameDisplay, ic,(x,y,w,h))

    smallText = pygame.font.SysFont("comicsansms",20)
    textSurf, textRect = text_objects(msg, smallText)
    textRect.center = ( (x+(w/2)), (y+(h/2)) )
    gameDisplay.blit(textSurf, textRect)

game_intro()
game_loop()
option1_loop()
pygame.quit()
quit()

问题是因为你一直按下pygame.mouse.get_pressed()，True一直是event.type = pygame.MOUSEBUTTONDOWN。当您按下第一个屏幕时，它会切换到第二个屏幕，看到该按钮被按下并自动点击按钮并切换到第三个屏幕。

您可以使用仅执行一次的button() - 当按钮从非按下状态变为按下状态时。但您必须将button_check()分为button_draw()和import pygame # --- constants --- (UPPER_CASE names) DISPLAY_WIDTH = 900 DISPLAY_HEIGHT = 600 BLACK = ( 0, 0, 0) WHITE = (255,255,255) RED = (250, 0, 0) GREEN = ( 0,250, 0) BRIGHT_RED = (200, 0, 0) BRIGHT_GREEN = ( 0,200, 0) # --- classes --- (CamelCase names) # empty # --- functions --- (lower_case names) def button_check(button): mouse = pygame.mouse.get_pos() click = pygame.mouse.get_pressed() if button['rect'].collidepoint(mouse): if click[0] == 1 and button['action']: button['action']() def button_draw(button): font = pygame.font.SysFont("comicsansms", 20) mouse = pygame.mouse.get_pos() if button['rect'].collidepoint(mouse): color = button['ac'] else: color = button['ic'] pygame.draw.rect(game_display, color, button['rect']) image, rect = text_objects(button['msg'], font) rect.center = button['rect'].center game_display.blit(image, rect) def text_objects(text, font): image = font.render(text, True, BLACK) rect = image.get_rect() return image, rect def message_display(text): font = pygame.font.Font("Arial" ,60) image, rect = text_objects(text, font) rect.center = game_display_rect.center game_display.blit(image, rect) pygame.display.update() def quit_game(): pygame.quit() quit() def game_intro(): font = pygame.font.SysFont("comicsansms", 115) game_display.fill(WHITE) image, rect = text_objects("A math's game", font) rect.center = game_display_rect.center game_display.blit(image, rect) buttons = [ { 'msg': 'GO!', 'rect': pygame.Rect(150, 450, 100, 50), 'ac': GREEN, 'ic': BRIGHT_GREEN, 'action': game_loop, }, { 'msg': 'Quit', 'rect': pygame.Rect(550, 450, 100, 50), 'ac': RED, 'ic': BRIGHT_RED, 'action': game_loop } ] while True: for event in pygame.event.get(): if event.type == pygame.QUIT: quit_game() elif event.type == pygame.MOUSEBUTTONDOWN: button_check(buttons[0]) button_check(buttons[1]) button_draw(buttons[0]) button_draw(buttons[1]) pygame.display.update() def game_loop(): font = pygame.font.SysFont("comicsansms",48) game_display.fill(WHITE) image, rect = text_objects("A math's game", font) rect.center = (game_display_rect.centerx, 100) game_display.blit(image, rect) image, rect = text_objects("Pick a choice", font) rect.center = (game_display_rect.centerx, 200) game_display.blit(image, rect) image, rect = text_objects("1 QUESTION", font) rect.center = (game_display_rect.centerx, 280) game_display.blit(image, rect) buttons = [ { 'msg': 'Option1', 'rect': pygame.Rect(120, 350, 300, 150), 'ac': RED, 'ic': BRIGHT_RED, 'action': option1_loop, }, { 'msg': 'Option2', 'rect': pygame.Rect(520, 350, 300, 150), 'ac': RED, 'ic': BRIGHT_RED, 'action': None } ] while True: for event in pygame.event.get(): if event.type == pygame.QUIT: quit_game() elif event.type == pygame.MOUSEBUTTONDOWN: button_check(buttons[0]) button_check(buttons[1]) button_draw(buttons[0]) button_draw(buttons[1]) pygame.display.update() def option1_loop(): font = pygame.font.SysFont("comicsansms",48) game_display.fill(WHITE) image, rect = text_objects("A math's game", font) rect.center = (game_display_rect.centerx, 100) game_display.blit(image, rect) image, rect = text_objects("Pick a choice", font) rect.center = (game_display_rect.centerx, 200) game_display.blit(image, rect) image, rect = text_objects("2 QUESTION", font) rect.center = (game_display_rect.centerx, 280) game_display.blit(image, rect) buttons = [ { 'msg': 'Option1.1', 'rect': pygame.Rect(120, 350, 300, 150), 'ac': RED, 'ic': BRIGHT_RED, 'action': option1_loop, }, { 'msg': 'Option2.1', 'rect': pygame.Rect(520, 350, 300, 150), 'ac': RED, 'ic': BRIGHT_RED, 'action': None } ] while True: for event in pygame.event.get(): if event.type == pygame.QUIT: quit_game() elif event.type == pygame.MOUSEBUTTONDOWN: button_check(buttons[0]) button_check(buttons[1]) button_draw(buttons[0]) button_draw(buttons[1]) pygame.display.update() # --- main --- pygame.init() game_display = pygame.display.set_mode((DISPLAY_WIDTH, DISPLAY_HEIGHT)) game_display_rect = game_display.get_rect() pygame.display.set_caption("A MATH'S GAME") game_intro()
