[已解决]零基础入门学习Python85讲

翁坤1125

大概十六分钟左右打的代码
个人认为和小甲鱼打的一样啊

import pygame
import sys
from pygame.locals import *
from random import *

class Ball(pygame.sprite.Sprite):
    def __init__(self,image,position,speed):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load(image).convert_alpha()
        self.rect = self.image.get_rect()
        self.rect.left,self.rect.top = position
        self.speed = speed

def main():
    pygame.init()
    #自己的素材
    ball_image = "球.png"
    bg_image = "背景.png"

    running = True

    bg_size = width,height = 600,315#自己的图片大小
    screen = pygame.display.set_mode(bg_size)
    pygame.display.set_caption("P l a y a b a l l")#自己的标题

    background = pygame.image.load(bg_image).convert_alpha()

    balls = []

    for i in range(5):
        position = randint(0,width-46),randint(0,height-46)#自己的图片大小
        speed = [randint(-10,10),randint(-10,10)]
        ball = Ball(ball_image,position,speed)
        balls.append(ball)

    clock = pygame.time.Clock()

    while running:
        for event in pygame.event.get():
            if event.type == QUIT:
                sys.exit()

        screen.blit(background,(0,0))

        for each in balls:
            screen.blit(each,image,each.rect)

        pygame.display.flip()
        clock.tick(30)

if __name__ == "__main__":
    main()

哪里错了啊
显示NameError: name 'image' is not defined

这样试试：

import pygame
import sys
from pygame.locals import *
from random import *


class Ball(pygame.sprite.Sprite):
    def __init__(self, image, position, speed):
        pygame.sprite.Sprite.__init__(self)

        self.image = pygame.image.load(image).convert_alpha()
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = position
        self.speed = speed


def main():
    pygame.init()

    ball_image = "球.png"
    bg_image = "背景.png"

    running = True

    bg_size = width, height = 600, 315
    screen = pygame.display.set_mode(bg_size)
    pygame.display.set_caption("P l a y a b a l l")

    background = pygame.image.load(bg_image).convert_alpha()

    balls = []

    for i in range(5):
        position = randint(0, width - 46), randint(0, height - 46)
        speed = [randint(-10, 10), randint(-10, 10)]
        ball = Ball(ball_image, position, speed)
        balls.append(ball)

    clock = pygame.time.Clock()

    while running:
        for event in pygame.event.get():
            if event.type == QUIT:
                sys.exit()

        screen.blit(background, (0, 0))

        for each in balls:
            screen.blit(each, ball.image, each.rect)

        pygame.display.flip()
        clock.tick(30)
