python pygame讲解

首先，先安装。。。不用我说了吧，python3.7（打开https://python.org/）具体怎么下，找别的教材去。。。

下一步，需要安装pygame。具体方法：先打开cmd：

点击“确定”打开，输入下面代码：

按下Enter键后如图所示：

额。。。这是错误输出。。。（输出前带Traceback）

反正你们只需要在网上搜“如何安装python模块”即可。

下一步，先导入pygame:

import pygame

pygame有一个特性：需要进行model init，就是模块初始化。代码：

pygame.init()

接下来要创建窗口了：

pygame.display.set_mode((640, 460), 0, 32)        # 第一个元组是用来设定窗口大小的，第一个元                                                                                # 素是高，第二个是宽；剩下的形参为默认设置

今天先介绍到这里，持续更新哦~

给大家看看我用pygame编的程序，有声音哦：

import pygame


class Ball(pygame.sprite.Sprite):
    def __init__(self, image_file, speed, location=None):
        pygame.sprite.Sprite.__init__(self)
        if location is None:
            location = [0, 0]
        self.image = pygame.image.load(image_file)
        self.rect = self.image.get_rect()
        self.rect.left, self.rect.top = location
        self.speed = speed

    def move(self):
        global points, score_text
        self.rect = self.rect.move(self.speed)
        if self.rect.left < 0 or self.rect.right > screen.get_width():
            self.speed[0] = -self.speed[0]
            if self.rect.top < screen.get_height():
                hit_wall.play()

        if self.rect.top <= 0:
            self.speed[1] = -self.speed[1]
            points = points + 1
