如何在python平台游戏中制作另一个关卡

Question

I want to make it so when you walk off the screen to the right it will enter level 2, but I have no clue on how to do this.

I also have a platform glitch but no one knows how to answer it on the post I made so I guess I'll just leave it because I can't fix it.

This is my code:

import pygame

pygame.init()

bg = pygame.image.load('C:\Python34/2d/bg.png')
player1 = pygame.image.load('C:\Python34/2d/player.png')
screen = pygame.display.set_mode((800,600))

pygame.display.set_caption("use arows")

movex = 0

class player:

    def __init__(self ,x, y):
        self.x = x
        self.y = y
        self.width = 112
        self.height = 112
        self.velocity = 0
        self.falling = False
        self.onGround = False

    def jump(self):
        if(self.onGround == False):
            return

        self.velocity = 8
        self.onGround = False

    def detectCollisions(self,x1,y1,w1,h1,x2,y2,w2,h2):
        if (x2+w2>=x1>=x2 and y2+h2>=y1>=y2):
            return True
        elif (x2+w2>=x1+w1>=x2 and y2+h2>=y1>=y2):
            return True
        elif (x2+w2>=x1>=x2 and y2+h2>=y1+h1>=y2):
            return True
        elif (x2+w2>=x1+w1>=x2 and y2+h2>=y1+h1>=y2):
            return True    
        else:
            return False

    def update(self, gravity, blockList):
        if (self.velocity < 0):
            self.falling = True

        collision = False
        blockX,blockY =  0,0
        for block in blockList:

            collision = self.detectCollisions(self.x, self.y, self.width, self.height, block.x, block.y, block.width, block.height )
            if collision == True:
                blockx = block.x
                blocky = block.y
                break

        if(collision == True):
            if self.falling == True:
                self.falling = False
                self.onGround = True
                self.velocity = 0
                self.y = blocky - self.height

        if (self.onGround == False):
            self.velocity += gravity
        self.y -= self.velocity

    def render(self,screen):
        screen.blit(player1,(self.x,self.y))

class Block:
    def __init__ (self, x, y):
       self.x = x
       self.y = y

I store my levels in text files, but the way you have it set up will work. Just test if the player is past the right edge of the map, (eg: if playerX > 1200 ) then reload the map as the second map, (basically, just have an active map that copies other maps onto it for active use) Then set the playerX to 0 or something.

For my game, I have all of my maps stored as text files with them named World,X,Y. I load them with file = open(''+(str(World))+','+(str(X))+','+(str(Y))+'','r') (I don't care what people think of how I do my strings. :P) Then it it mostly automated.
