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:
self.closestpoint_y = self.ball_y
self.collision_sign_y = 3
#定义球拍到圆心最近点与圆心的距离
self.distance = math.sqrt(math.pow(self.closestpoint_x-self.ball_x,2)+math.pow(self.closestpoint_y-self.ball_y,2))
#球在球拍上左、上中、上右3种情况的碰撞检测
