python编写一个贪食蛇游戏

好的，我可以帮您解答关于python编写贪食蛇游戏的问题。您可以参考以下代码：

import pygame
import time
import random
 
pygame.init()
 
white = (255, 255, 255)
black = (0, 0, 0)
red = (213, 50, 80)
green = (0, 255, 0)
blue = (50, 153, 213)
 
display_width = 800
display_height = 600
 
gameDisplay = pygame.display.set_mode((display_width, display_height))
pygame.display.set_caption('Slither')
 
clock = pygame.time.Clock()
 
block_size = 10
 
def snake(block_size, snakeList):
    for XnY in snakeList:
        pygame.draw.rect(gameDisplay, green, [XnY[0], XnY[1], block_size, block_size])
 
def message_to_screen(msg, color):
    font = pygame.font.SysFont(None, 25)
    screen_text = font.render(msg, True, color)
    gameDisplay.blit(screen_text, [display_width/6, display_height/2])
 
def gameloop():
    gameExit = False
    gameOver = False
 
    lead_x = display_width / 2
    lead_y = display_height / 2
 
    lead_x_change = 0
    lead_y_change = 0
 
    snakeList = []
    snakeLength = 1
 
    randAppleX = round(random.randrange(0, display_width - block_size) / 10.0) * 10.0
    randAppleY = round(random.randrange(0, display_height - block_size) / 10.0) * 10.0
 
    while not gameExit:
 
        while gameOver == True:
            gameDisplay.fill(white)
            message_to_screen("Game over, press C to play again or Q to quit", red)
            pygame.display.update()
 
            for event in pygame.event.get():
                if event.type == pygame.KEYDOWN:
                    if event.key == pygame.K_q:
                        gameExit = True
                        gameOver = False
                    if event.key == pygame.K_c:
                        gameloop()
 
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                gameExit = True
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    lead_x_change = -block_size
                    lead_y_change = 0
                elif event.key == pygame.K_RIGHT:
                    lead_x_change = block_size
                    lead_y_change = 0
                elif event.key == pygame.K_UP:
                    lead_y_change = -block_size
                    lead_x_change = 0
                elif event.key == pygame.K_DOWN:
                    lead_y_change = block_size
                    lead_x_change = 0
 
        if lead_x >= display_width or lead_x < 0 or lead_y >= display_height or lead_y < 0:
            gameOver = True
 
        lead_x += lead_x_change
        lead_y += lead_y_change
 
        gameDisplay.fill(white)
 
        pygame.draw.rect(gameDisplay, red, [randAppleX, randAppleY, block_size, block_size])
 
        snakeHead = []
        snakeHead.append(lead_x)
        snakeHead.append(lead_y)
        snakeList.append(snakeHead)
        if len(snakeList) > snakeLength:
            del snakeList[0]
 
        for eachSegment in snakeList[:-1]:
            if eachSegment == snakeHead:
                gameOver = True
 
        snake(block_size, snakeList)
 
        pygame.display.update()
 
        if lead_x == randAppleX and lead_y == randAppleY:
            randAppleX = round(random.randrange(0, display_width - block_size) / 10.0) * 10.0
            randAppleY = round(random.randrange(0, display_height - block_size) / 10.0) * 10.0
            snakeLength += 1
 
        clock.tick(15)
 
    pygame.quit()
    quit()
 
gameloop()

希望这个例子能帮助到您！
