在pygame中创建蛇游戏时遇到问题

如何解决在pygame中创建蛇游戏时遇到问题

早上好，我今天设法用pygame做我的蛇游戏，但是在一定长度（4）上，我的蛇不能上去，我尝试了几种方法，但都没有成功有效

我也接受对我的代码的任何批评，我对编程还很陌生

编辑：发现错误在#player部分的for循环中，当我删除这些错误时，错误结束了，但是蛇的尸体不能超过3个

代码：

import pygame
import sys
import math
import random

oldx = 0
oldy = 0
newx = []
newy = []
for i in range(0,20):
    newx.append(0)
    newy.append(0)

clock = pygame.time.Clock()  # lockar o FPS
pygame.init()  # inicar o pygame
height,width = 400,400
screen = pygame.display.set_mode((width,height),32)  # criar tela em width/height ou x/y
pygame.display.set_caption('Cobrin')
red = (255,0)
p,u,i,o = 0,0
snake_amount = 0
y = 180
x = 180
vel = 20
macaX,macaY = random.randint(0,19) * 20,random.randint(0,19) * 20

# score
font = pygame.font.Font('freesansbold.ttf',20) # fonte e tamanho
textX = 10
textY = 10


# gerador de maça
def gerador_maca(macax,macay):
    pygame.draw.rect(screen,red,(macax,macay,20,20))


# colisao
def isCollision(enemyX,enemyY,bulletX,bulletY):
    distance = math.sqrt(math.pow(enemyX - bulletX,2) + math.pow(enemyY - bulletY,2))
    if distance < 20:
        return True
    else:
        return False


# Mostrar o score
def show_score(scorex,scorey):
    score = font.render('Score: ' + str(snake_amount),True,(255,255,255)) # Texto,se vai aparecer ou nao,e a cor
    screen.blit(score,(scorex,scorey))  # blit é desenhar


# Teclas
def walk(testy,testu,testi,testo):
    global x
    global y
    if testy == 1:
        y += 20
    if testu == 1:
        x += 20
    if testi == 1:
        y -= 20
    if testo == 1:
        x -= 20


# Bordas
def bordas():
    global x
    global y
    if x > 380:
        x = 0
    if y > 380:
        y = 0
    if x < 0:
        x = 380
    if y < 0:
        y = 380


# Desenhar corpo
def desenhar_corpo(drawx,drawy):
    pygame.draw.rect(screen,0),(drawx,drawy,20))


# Gerar primeira maça
gerador_maca(macaX,macaY)
while True:

    # antes de rodar
    clock.tick(10)
    screen.fill((10,180,10))
    bordas()
    snake_body = []

    # teclas
    for event in pygame.event.get():  # pega cada acontecimento que acontece dentro da janela do pygame
        if event.type == pygame.QUIT:  # se clicar no X vai fechar o game
            pygame.quit()
            sys.exit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_s:
                p,o = 1,0
            elif event.key == pygame.K_d:
                p,1,0
            elif event.key == pygame.K_w:
                p,0
            elif event.key == pygame.K_a:
                p,1

    # maçã
    gerador_maca(macaX,macaY)

    # colisao
    if isCollision(x,y,macaX,macaY):
        macaX,19,) * 20,19) * 20
        gerador_maca(macaX,macaY)
        snake_amount += 1

    # player
    if snake_amount >= 1:
        if snake_amount >= 3:
            for i in range(snake_amount,2,-1):
                newx[i-2] = newx[i-3]
                newy[i-2] = newy[i-3]
                desenhar_corpo(newx[i-2],newy[i-2])
                print(i)
        if snake_amount >= 2:
            newx[0] = oldx
            newy[0] = oldy
            desenhar_corpo(newx[0],newy[0])
        oldx = x
        oldy = y
        desenhar_corpo(oldx,oldy)
    walk(p,o)
    desenhar_corpo(x,y)

    # placar
    show_score(textX,textY)
    pygame.display.update()

解决方法

尝试一下：

import pygame

import time #  you didn't import time

 
pygame.init()
#This will initialize all imported pygame modules
:
:
:
pygame.quit()
#This will uninitialize all pygame modules
    quit()
 
gameLoop()
