Python Pygame事件错误
我最近开始在pygame中制作蛇。首先,我是在没有面向对象编程的情况下编写代码的。当我注意到使用类会更好时,我编辑了代码。前三次,蛇正常移动,但之后当我按下左箭头、右箭头或向下箭头时,蛇向下移动。 当我没有课的时候,这个程序就按它应该的方式运行。现在没有了。你能帮我吗 这是我的代码:Python Pygame事件错误,python,python-3.x,events,pygame,Python,Python 3.x,Events,Pygame,我最近开始在pygame中制作蛇。首先,我是在没有面向对象编程的情况下编写代码的。当我注意到使用类会更好时,我编辑了代码。前三次,蛇正常移动,但之后当我按下左箭头、右箭头或向下箭头时,蛇向下移动。 当我没有课的时候,这个程序就按它应该的方式运行。现在没有了。你能帮我吗 这是我的代码: import pygame, math, random pygame.init() screen = pygame.display.set_mode((640,640)) pygame.display.set_

正方形=[]
对于范围内的i(640):
如果i%32==0:
正方形。附加(i)
food=pygame.image.load('fruit.png')

返回math.sqrt(math.pow(obsX-x,2)+math.pow(obsY-y,2))问题就在这里
snake.dirLeft, dirDown, dirRight = False, False, False
应该是什么
snake.dirLeft, snake.dirDown, snake.dirRight = False, False, False
在python中,除非您从tuple/list中解包值,否则不建议使用多个assignment。如您所见,这将更具可读性:)
还有另一个问题,因为蛇在创建蛇实例的瞬间,他的身体保持静止,这里有一个可能的解决方案
class Snake(object):
def __init__(self):
self.x, self.y = 320, 320
self.dirUp, self.dirDown = False, False
self.dirLeft, self.dirRight = False, False
self.snakeImg = [pygame.image.load('snakeblock.png')
for i in range(len(self.body))]
@property
def body(self):
return [(self.x, self.y)]
但是你还是得想办法增加它的体重问题就在这里
snake.dirLeft, dirDown, dirRight = False, False, False
应该是什么
snake.dirLeft, snake.dirDown, snake.dirRight = False, False, False
