这里有新鲜出炉的Python多线程编程,程序狗速度看过来!
Python 是一种面向对象、解释型计算机程序设计语言,由Guido van Rossum于1989年底发明,第一个公开发行版发行于1991年。Python语法简洁而清晰,具有丰富和强大的类库。它常被昵称为胶水语言,它能够把用其他语言制作的各种模块(尤其是C/C++)很轻松地联结在一起。
这篇文章主要介绍了Python实现的弹球小游戏,可实现类似乒乓球游戏的键盘控制底部挡板移动碰撞小球的游戏功能,需要的朋友可以参考下
本文实例讲述了Python实现的弹球小游戏。分享给大家供大家参考,具体如下:
弹球
1. Ball 类
draw负责移动Ball
碰撞检测,反弹,Ball检测Paddle
2.Paddle类
draw负责移动Paddle
碰撞检测,确定能不能继续
监听键盘事件
3.主循环
绘制Ball和Paddle
update
sleep
代码
- from Tkinter import *
- import random
- import time
- class Ball:
- def __init__(self, canvas, paddle, color):
- self.canvas = canvas
- self.paddle = paddle
- self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
- self.canvas.move(self.id, 245, 100)
- startx = [-3, -2, -1, 1, 2, 3]
- random.shuffle(startx)
- self.x = startx[0]
- self.y = -3
- self.canvas_height = self.canvas.winfo_height()
- self.canvas_width = self.canvas.winfo_width()
- self.hit_bottom = False
- def draw(self):
- self.canvas.move(self.id, self.x, self.y)
- pos = self.canvas.coords(self.id)#top-left bottom-right
- if (pos[1] <= 0 or self.hit_paddle(pos) == True):
- self.y = -self.y
- if (pos[0] <= 0 or pos[2] >= self.canvas_width):
- self.x = -self.x
- if (pos[3] >= self.canvas_height):
- self.hit_bottom = True
- def hit_paddle(self, pos):
- paddle_pos = self.canvas.coords(self.paddle.id)
- if (pos[2] >= paddle_pos[0] and pos[0] <= paddle_pos[2]):
- if (pos[3] >= paddle_pos[1] and pos[3] <= paddle_pos[3]):
- return True
- return False
- class Paddle:
- def __init__(self, canvas, color):
- self.canvas = canvas
- self.id = canvas.create_rectangle(0, 0, 100, 10, fill = color)
- self.x = 0
- self.canvas.move(self.id, 200, 300)
- self.canvas_width = self.canvas.winfo_width()
- self.canvas.bind_all("<Key-Left>", self.turn_left)
- self.canvas.bind_all("<Key-Right>", self.turn_right)
- def draw(self):
- pos = self.canvas.coords(self.id)
- if (pos[0] + self.x >= 0 and pos[2] + self.x <= self.canvas_width):
- self.canvas.move(self.id, self.x, 0)
- #self.x = 0
- def turn_left(self, event):
- self.x = -4
- def turn_right(self, event):
- self.x = 4
- tk = Tk()
- tk.title("Game")
- tk.resizable(0, 0)#not resizable
- tk.wm_attributes("-topmost", 1)#at top
- canvas = Canvas(tk, width = 500, height = 500, bd = 0, highlightthickness = 0)
- canvas.pack()
- tk.update()#init
- paddle = Paddle(canvas, 'blue')
- ball = Ball(canvas, paddle, 'red')
- while 1:
- if (ball.hit_bottom == False):
- ball.draw()
- paddle.draw()
- tk.update_idletasks()
- tk.update()
- time.sleep(0.01)
运行效果如下图:
希望本文所述对大家Python程序设计有所帮助。
