Python游戏开发——打砖块

打砖块游戏向来大家也不会很陌生，今天来用python来开发一下这个小游戏

1.引用对应数据库

import pygame
from pygame.locals import *
import sys,random,time,math

2.设计游戏窗口初始数据

定义窗口内容，内容主要包括屏幕大小、标题、背景颜色。

def __init__(self,*args,**kw):
        self.window_length = 600
        self.window_wide = 500
        #绘制游戏窗口，设置窗口尺寸
        self.game_window = pygame.display.set_mode((self.window_length,self.window_wide))
        #设置游戏窗口标题
        pygame.display.set_caption("CatchBallGame")
        #定义游戏窗口背景颜色参数
        self.window_color = (135,206,250)

    def backgroud(self):
        #绘制游戏窗口背景颜色
        self.game_window.fill(self.window_color)

3.设计球类

class Ball(object):
    '''创建球类'''
    def __init__(self,*args,**kw):
        #设置球的半径、颜色、移动速度参数
        self.ball_color = (255,215,0)
        self.move_x = 1
        self.move_y = 1
        self.radius = 10

    def ballready(self):
        #设置球的初始位置、
        self.ball_x = self.mouse_x
        self.ball_y = self.window_wide-self.rect_wide-self.radius
        #绘制球，设置反弹触发条件
        pygame.draw.circle(self.game_window,self.ball_color,(self.ball_x,self.ball_y),self.radius)

    def ballmove(self):
        #绘制球，设置反弹触发条件
        pygame.draw.circle(self.game_window,self.ball_color,(self.ball_x,self.ball_y),self.radius)
        self.ball_x += self.move_x
        self.ball_y -= self.move_y
        #调用碰撞检测函数
        self.ball_window()
        self.ball_rect()
        #每接5次球球速增加一倍
        if self.distance < self.radius:
            self.frequency += 1
            if self.frequency == 5:
                self.frequency = 0
                self.move_x += self.move_x
                self.move_y += self.move_y
                self.point += self.point
        #设置游戏失败条件
        if self.ball_y > 520:
            self.gameover = self.over_font.render("Game Over",False,(0,0,0))
            self.game_window.blit(self.gameover,(100,130))
            self.over_sign = 1

4.设计球拍类

class Rect(object):
    '''创建球拍类'''
    def __init__(self,*args,**kw):
        #设置球拍颜色参数
        self.rect_color = (255,0,0)
        self.rect_length = 100
        self.rect_wide = 10

    def rectmove(self):
        #获取鼠标位置参数
        self.mouse_x,self.mouse_y = pygame.mouse.get_pos()
        #绘制球拍，限定横向边界
        if self.mouse_x >= self.window_length-self.rect_length//2:
            self.mouse_x = self.window_length-self.rect_length//2
        if self.mouse_x <= self.rect_length//2:
            self.mouse_x = self.rect_length//2
        pygame.draw.rect(self.game_window,self.rect_color,((self.mouse_x-self.rect_length//2),(self.window_wide-self.rect_wide),self.rect_length,self.rect_wide))

5.设计砖块类

class Brick(object):
    def __init__(self,*args,**kw):
        #设置砖块颜色参数
        self.brick_color = (139,126,102)
        self.brick_list = [[1,1,1,1,1,1],[1,1,1,1,1,1],[1,1,1,1,1,1],[1,1,1,1,1,1],[1,1,1,1,1,1]]
        self.brick_length = 80
        self.brick_wide = 20

    def brickarrange(self):
        for i in range(5):
            for j in range(6):
                self.brick_x = j*(self.brick_length+24)
                self.brick_y = i*(self.brick_wide+20)+40
                if self.brick_list[i][j] == 1:
                    #绘制砖块
                    pygame.draw.rect(self.game_window,self.brick_color,(self.brick_x,self.brick_y,self.brick_length,self.brick_wide))
                    #调用碰撞检测函数
                    self.ball_brick()
                    if self.distanceb < self.radius:
                        self.brick_list[i][j] = 0
                        self.score += self.point
        #设置游戏胜利条件
        if self.brick_list == [[0,0,0,0,0,0],[0,0,0,0,0,0],[0,0,0,0,0,0],[0,0,0,0,0,0],[0,0,0,0,0,0]]:
            self.win = self.win_font.render("You Win",False,(0,0,0))
            self.game_window.blit(self.win,(100,130))
            self.win_sign = 1

6.设计分数类

class Score(object):
    '''创建分数类'''
    def __init__(self,*args,**kw):
        #设置初始分数
        self.score = 0
        #设置分数字体
        self.score_font = pygame.font.SysFont('arial',20)
        #设置初始加分点数
        self.point = 1
        #设置初始接球次数
        self.frequency = 0

    def countscore(self):
        #绘制玩家分数
        my_score = self.score_font.render(str(self.score),False,(255,255,255))
        self.game_window.blit(my_score,(555,15))

class GameOver(object):
    '''创建游戏结束类'''
    def __init__(self,*args,**kw):
        #设置Game Over字体
        self.over_font = pygame.font.SysFont('arial',80)
        #定义GameOver标识
        self.over_sign = 0

class Win(object):
    '''创建游戏胜利类'''
    def __init__(self,*args,**kw):
        #设置You Win字体
        self.win_font = pygame.font.SysFont('arial',80)
        #定义Win标识
        self.win_sign = 0

7.设计碰撞事件类

class Collision(object):
    '''碰撞检测类'''
    #球与窗口边框的碰撞检测
    def ball_window(self):
        if self.ball_x <= self.radius or self.ball_x >= (self.window_length-self.radius):
            self.move_x = -self.move_x
        if self.ball_y <= self.radius:
            self.move_y = -self.move_y

    #球与球拍的碰撞检测
    def ball_rect(self):
        #定义碰撞标识
        self.collision_sign_x = 0
        self.collision_sign_y = 0

        if self.ball_x < (self.mouse_x-self.rect_length//2):
            self.closestpoint_x = self.mouse_x-self.rect_length//2
            self.collision_sign_x = 1
        elif self.ball_x > (self.mouse_x+self.rect_length//2):
            self.closestpoint_x = self.mouse_x+self.rect_length//2
            self.collision_sign_x = 2
        else:
            self.closestpoint_x = self.ball_x
            self.collision_sign_x = 3

        if self.ball_y < (self.window_wide-self.rect_wide):
            self.closestpoint_y = (self.window_wide-self.rect_wide)
            self.collision_sign_y = 1
        elif self.ball_y > self.window_wide:
            self.closestpoint_y = self.window_wide
            self.collision_sign_y = 2
        else:

8.主函数
