我正在尝试使用带有类的pygame创建自己的游戏,但我的问题是我无法理解为什么我的程序无法正常运行
import pygame
import time
import random
import sys
pygame.init()
screen = pygame.display.set_mode((1280, 720))
pygame.display.set_caption("this game")
class Background:
def __init__(self, x, y):
self.xpos = x
self.ypos = y
picture = pygame.image.load("C:/images/dunes.jpg")
picture = pygame.transform.scale(picture, (1280, 720))
def draw(self):
pygame.surface.Surface.blit(picture, (self.xpos, self.ypos))
class Monster:
def __init__(self, x, y):
self.xpos = x
self.ypos = y
def move_left(self):
self.xpos =- 5
def move_right(self):
self.xpos =+ 5
def jump(self):
for x in range(1, 10):
self.ypos =-1
pygame.display.show()
for x in range(1, 10):
self.ypos =+1
pygame.display.show()
picture = pygame.image.load("C:/pics/hammerhood.png")
picture = pygame.transform.scale(picture, (200, 200))
def draw(self):
pygame.surface.Surface.blit(picture, (self.xpos, self.ypos))
class enemy:
def __init__(self, x, y):
self.xpos = x
self.ypos = y
picture = pygame.image.load("C:/pics/dangler_fish.png")
picture = pygame.transform.scale(picture, (200, 200))
def teleport(self):
self.xpos = random.randint(1, 1280)
self.pos= random.randint(1, 720)
def draw(self):
pygame.surface.Surface.blit(picture, (self.xpos, self.ypos))
while True:
ice = Background(720, 360)
hammerhood = Monster(200, 500)
fish = enemy(0, 0)
fish.teleport()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
if pygame.event == pygame.K_d:
hammerhood.move_right()
if pygame.event == pygame.K_a:
hammerhood.move_left()
if pygame.event == pygame.K_w:
hammerhood.jump()
hammerhood.draw()
ice.draw()
fish.draw()
对我说的是,在抽奖中的第49行
pygame.surface.Surface.blit(picture, (self.xpos, self.ypos))
NameError: name 'picture' is not defined
我已经尝试了所有方法,还有另一个项目是我从互联网上复制的,这与在课堂上画图的方式完全相同,但是在此项目中,它不起作用
最佳答案
您可以在班级顶层定义图片,从而使其成为班级属性。要通过某种方法访问它,您必须使用self. picture
关于python - 为什么Pygame Blit不能在类里面工作,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/53238706/
