所以我写这段代码是为了学校作业,我应该使用pygame并显示一些文本。我把这些文本放在不同的页面上,如果单击屏幕,它将显示下一个屏幕。
以下是我目前所拥有的:
import pygame
pygame.init()
pygame.font.init()
# defining the screen
SIZE = (1000, 700)
screen = pygame.display.set_mode(SIZE)
# define time
clock = pygame.time.Clock()
#define button
button = 0
# define font
fontIntro = pygame.font.SysFont("Times New Roman",30)
# define draw scene
def drawIntro(screen):
#start
if button > 0:
screen.fill((0, 0, 0))
text = fontIntro.render("Sigle click to start", 1, (255,255,255))
screen.blit(text, (300, 300, 500, 500))
pygame.display.flip()
#page1
if button == 1:
screen.fill((0, 0, 0))
text = fontIntro.render("page 1", True, (255, 255, 255))
pygame.display.flip()
#page2
if button == 1:
screen.fill((0, 0, 0))
text = fontIntro.render("page 2", True, (255, 255, 255))
screen.blit(text, (300,220,500,200))
pygame.display.flip()
#page3
if button == 1:
screen.fill((0, 0, 0))
text = fontIntro.render("page3", True, (255, 255, 255))
screen.blit(text, (200,190,500,200))
pygame.display.flip()
running = True
while running:
for evnt in pygame.event.get():
if evnt.type == pygame.QUIT:
running = False
if evnt.type == pygame.MOUSEMOTION:
mx,my = evnt.pos
print(evnt.pos)
drawIntro(screen)
pygame.quit()
虽然它不起作用,但有人能帮忙吗?!谢谢
您在一开始就定义了button = 0
,但在主循环中永远不会更改其值。在drawIntro
函数中,您可以选中if button > 0
或if button == 1
很明显,你从来没有执行过任何一个if
语句。
您需要通过调用pygame.mouse.get_pressed()
来抓住鼠标按钮,并了解如何正确切换到下一页。
顺便说一句,您还有三次if button == 1
,我想这不是您想要的,因为if
语句在编写时会立即执行,所以您的第3页会立即显示。您需要一些计数器来跟踪下次按下鼠标按钮时需要显示的页面。
当用户按下鼠标按钮时,需要增加button
计数器。
drawIntro
函数不应在每个pygame.MOUSEMOTION
事件的事件循环中调用一次,而应在主while
循环中调用。此外,将MOUSEMOTION
更改为MOUSEBUTTONDOWN
,以使每次单击的button
增加一次。
drawIntro
函数中的条件语句不正确。
import pygame
pygame.init()
SIZE = (1000, 700)
screen = pygame.display.set_mode(SIZE)
clock = pygame.time.Clock()
button = 0
fontIntro = pygame.font.SysFont("Times New Roman",30)
def drawIntro(screen):
#start
if button == 0: # == 0
screen.fill((0, 0, 0))
text = fontIntro.render("Sigle click to start", 1, (255,255,255))
screen.blit(text, (300, 300, 500, 500))
elif button == 1: #page1
screen.fill((0, 0, 0))
text = fontIntro.render("page 1", True, (255, 255, 255))
screen.blit(text, (300,220,500,200))
elif button == 2: #page2
screen.fill((0, 0, 0))
text = fontIntro.render("page 2", True, (255, 255, 255))
screen.blit(text, (300,220,500,200))
elif button == 3: #page3
screen.fill((0, 0, 0))
text = fontIntro.render("page3", True, (255, 255, 255))
screen.blit(text, (200,190,500,200))
running = True
while running:
for evnt in pygame.event.get():
if evnt.type == pygame.QUIT:
running = False
if evnt.type == pygame.MOUSEBUTTONDOWN: # Once per click.
button += 1
drawIntro(screen)
pygame.display.flip()
pygame.quit()
