如何在pygame中一起制作两个文件？

Question

我正在使用 pygame 制作游戏，我将每个部分都放在一个单独的文件中，例如主页、说明页、实际游戏等，我不知道如何将它们放在一起。我曾考虑过使用 这段代码

from graphics import*

w = GraphWin("Window", 600,400)

playing = True
while playing:
    click = w.getMouse()
    potato = click.getX()
    carrot = click.getY()

    if potato < 300 and carrot < 200:
        newWin = GraphWin("New", 200, 200)
    if potato > 300 and carrot > 200:
        w.setBackground("blue")
    if potato < 300 and carrot > 200:
        playing = False

    w.close()
    n = GraphWin("Homepage", 500, 200)
    n.getMouse()
    n.close()

但我仍然不知道如何将它们放在一起。你能帮我看看如何让这两个文件放在一起吗？这个文件是主页：

from graphics import* 
import pygame
import sys
import random 
from time import sleep

padWidth = 500 #the width the of game 
padHeight = 600 # the length of the game
white = (255,255,255)
black = (0,0,0)
red = (255,0,0)

def writeIns(text):
    global gamePad
    textfont = pygame.font.Font('Ranchers-Regular.ttf', 29) #textfont of the game message 
    text = textfont.render(text, True, red) #red text
    textpos = (158,417)
    gamePad.blit(text, textpos) #print the text
    pygame.display.update()
    
def drawObject(obj, x, y):
    global gamePad
    gamePad.blit(obj, (int(x), int(y)))

def initGame():
    global gamePad, clock, background
    pygame.init()
    gamePad = pygame.display.set_mode((padWidth, padHeight))
    pygame.display.set_caption('Shooting game') #the title of the game
    clock = pygame.time.Clock()

def runGame():
    global gamePad, clock, background
    
    onGame = False
    while not onGame:
        for event in pygame.event.get():
            if event.type in [pygame.QUIT]:
                pygame.quit()
                sys.exit()
                
        drawObject(background, 0, 0) #display the background 

        
        pygame.draw.rect(gamePad, black, (120,400,250,70))

        writeIns('INSTRUCTIONS')
        
        pygame.display.update()

        clock.tick(60)

    pygame.quit()
       

initGame()
runGame()

这个是说明页

import pygame
import sys
import random 
from time import sleep


padWidth = 500 #the width the of game 
padHeight = 600 # the length of the game
red = (255,0,0)

def writeExit(text):
    global gamePad
    textfont = pygame.font.Font('Ranchers-Regular.ttf', 20) #textfont of the game message 
    text = textfont.render(text, True, red) #black text
    textpos = (625, 60)
    gamePad.blit(text, textpos) #print the text
    pygame.display.update()
    
def drawObject(obj, x, y):
    global gamePad
    gamePad.blit(obj, (int(x), int(y)))

def initGame():
    global gamePad, clock, instructions
    pygame.init()
    gamePad = pygame.display.set_mode((padWidth, padHeight))
    pygame.display.set_caption('shooting game') #the title of the game
    instructions = pygame.image.load('instructions.png') #import the background image
    clock = pygame.time.Clock()

def runGame():
    global gamePad, clock, instructions
    onGame = False
    while not onGame:
        for event in pygame.event.get():
            if event.type in [pygame.QUIT]:
                pygame.quit()
                sys.exit()
        drawObject(instructions, 0, 0)
        pygame.display.update()

        clock.tick(60)
        
    pygame.quit()

initGame()
runGame()

所以，我希望，当从主页按下按钮时，它会移动到说明页面。

要合并文件，您需要进行两个关键更改：

• 将其他源文件导入主文件
• 将导入的源代码转换为类以防止变量和函数重叠

这是工作代码。起始文件为gamex.py，导入文件为ghome.py和ginstructions.py。

gamex.py

from graphics import *

# import home and instructions
from ghome import home
from ginstructions import instructions


# call home screen
h = home()  # create instance of home
h.initGame()
h.runGame()

# call instructions screen
i = instructions()  # create instance of instructions
i.initGame()
i.runGame()


w = GraphWin("Window", 600,400)

playing = True
while playing:
    click = w.getMouse()
    potato = click.getX()
    carrot = click.getY()

    if potato < 300 and carrot < 200:
        newWin = GraphWin("New", 200, 200)
    if potato > 300 and carrot > 200:
        w.setBackground("blue")
    if potato < 300 and carrot > 200:
        playing = False

    w.close()
    n = GraphWin("Homepage", 500, 200)
    n.getMouse()
    n.close()    

ghome.py

from graphics import* 
import pygame

from time import sleep

class home():
    def __init__(self):
        self.padWidth = 500 #the width the of game 
        self.padHeight = 600 # the length of the game
        self.white = (255,255,255)

            self.writeIns('INSTRUCTIONS')
            pygame.display.update()
