Python实现的弹球小游戏示例,python弹球示例
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:
