python之我将如何向这个 pygame/python 代码添加一个开始屏幕

我有一个抓水果的游戏。

pygame.init() 
myname=input('What is your name') 
 
#set the window size 
window= pygame.display.set_mode((800,600) ,0,24) 
pygame.display.set_caption("Fruit Catch") 
 
#game variables 
gameover=pygame.image.load('gameover.jpg') 
myscore=0 
file = 'score.txt' 
eating=pygame.mixer.Sound('data/eating.wav') 
die=pygame.mixer.Sound('die.wav') 
mylives=3 
mouth_x=300 
fruit_x=250 
fruit_y=75 
fruitlist=['broccoli.gif','chicken.gif'] 
keyclicks=0 
#prepare for screen 
myfont=pygame.font.SysFont("Britannic Bold", 55) 
label1=myfont.render(myname, 1, (240, 0, 0)) 
label3=myfont.render(str(mylives), 1, (20, 255, 0)) 
#grapchics 
fruit=pygame.image.load('data/chicken.png') 
mouth=pygame.image.load('data/v.gif') 
backGr=pygame.image.load('data/kfc.jpg') 
backGr1=pygame.image.load('sj.jpg') 
#endless loop 
running=True 
while running: 
    if fruit_y>=460:#check if at bottom, if so prepare new fruit 
       fruit_x=random.randrange(50,530,1) 
       fruit_y=75 
       fruit=pygame.image.load('data/'+fruitlist[random.randrange(0,2,1)]) 
       caught= fruit_x>=mouth_x and fruit_x<=mouth_x+500 
    else:fruit_y+=5 
 
   #check collision 
    if fruit_y>=456: 
       mylives-=1 
    if fruit_y>=440: 
            if fruit_x>=mouth_x and fruit_x<=mouth_x+300 : 
                    myscore+=1 
                    fruit_y=600#move it off screen 
                    eating.play() 
 
    pygame.mouse.get_pressed()  
    for event in pygame.event.get(): 
            if (event.type==pygame.KEYDOWN): 
                if (event.key==pygame.K_LEFT): 
                        mouth_x-=55 
                        keyclicks+=1 
                if (event.key==pygame.K_RIGHT): 
                        mouth_x+=55 
                        keyclicks+=1  
            if event.type==MOUSEBUTTONDOWN and keyclicks>=2 : 
                pygame.quit() 
    label3=myfont.render(str(mylives), 1, (20, 255, 0)) 
    label2=myfont.render(str(myscore), 1, (20, 255, 0)) 
    text1='You caught'+str(myscore) 
    text3='Press the mouse to close the game' 
    label4=myfont.render(text1, 1, (135, 206, 250)) 
    myfont1=pygame.font.SysFont("Britannic Bold", 40) 
    label5=myfont1.render(text3, 1, (255, 0, 0)) 
 
    if mylives==0: 
       window.blit(gameover, (0,0)) 
       window.blit(label4, (500,400)) 
       die.play() 
       pygame.time.get_ticks 
       pygame.display.update() 
       running=False 
       webbrowser.open(file) 
 
    else: 
 
        window.blit(backGr,(0,0)) 
        window.blit(mouth, (mouth_x,440)) 
        window.blit(fruit,(fruit_x, fruit_y)) 
        window.blit(label1, (174, 537)) 
        window.blit(label2, (700, 157)) 
        window.blit(label3, (700, 400)) 
        window.blit(label5, (10, 0)) 
        pygame.display.update() 

上面的一切都有效，但我想给它添加一个开始屏幕，但不知道该怎么做。 我在想一些事情:

startscreen=pygame.image.load(filename) 
window.blit(startscreen, (0,0)) 
if event.type==MOUSEBUTTONDOWN: 
#then go in to the main loop 

有什么建议吗？

请您参考如下方法:

是的，您正朝着正确的方向前进，但是您需要一个无限循环，该循环会在 event.type==MOUSEBUTTONDOWN: 条件为真时中断。

你可以做这样的事情。

#import modules     
#pygame inititalising and image loading and others 
 
black=(0,0,0) 
end_it=False 
while (end_it==False): 
    window.fill(black) 
    myfont=pygame.font.SysFont("Britannic Bold", 40) 
    nlabel=myfont.render("Welcome "+myname+" Start Screen", 1, (255, 0, 0)) 
    for event in pygame.event.get(): 
        if event.type==MOUSEBUTTONDOWN: 
            end_it=True 
    window.blit(nlabel,(200,200)) 
    pygame.display.flip() 
 
#while running loop 
     #rest of the code 

所以将这段代码放在 while running: 循环之前
