Pygame游戏碰撞

Question

我需要编程任务帮助。我需要做到这一点，以便在碰撞时游戏中的方块互相反弹。下面的代码使用Pygame。我一直试图做几个小时，并继续跑到墙上。

import pygame 
from pygame.locals import * 
import time 

class Block: 
    def __init__(self,win,left,top, 
     width,height,color,velocity): 
     self.win = win 
     self.rect = pygame.Rect(left,top, 
      width,height) 
     self.color = color 
     self.velocity = velocity 
    def move(self): 
     self.rect = self.rect.move(
      self.velocity[0],self.velocity[1]) 
     if ((self.rect.top < 0) or 
      (self.rect.bottom > self.win.height)): 
       self.velocity[1] = -self.velocity[1] 
     if ((self.rect.left < 0) or 
      (self.rect.right > self.win.width)): 
       self.velocity[0] = -self.velocity[0] 
    def tupleRep(block): 
     return ((block.rect.left, block.rect.top),(block.rect.right,  block.rect.bottom)) 
     colliderect() 
    def draw(self): 
     pygame.draw.rect(self.win.surface, 
      self.color, self.rect,0) 

class BlockWindow: 
    def __init__(self,width,height,caption): 
     self.surface = pygame.display.set_mode((width,height)) 
     self.caption = caption 
     pygame.display.set_caption(self.caption) 
     self.height = height 
     self.width = width 
     self.blocks = [ ] 
     self.blocks.append(Block(self,300,80,50, 
      100,RED,[BASESPEED,-BASESPEED])) 
     self.blocks.append(Block(self,200,200,20, 
      20,GREEN,[-BASESPEED,-BASESPEED])) 
     self.blocks.append(Block(self,100,150,60, 
      60,BLUE,[-BASESPEED,BASESPEED])) 
     self.blocks.append(Block(self,100,100,70, 
      200,PURPLE,[BASESPEED,BASESPEED])) 
     self.blocks.append(Block(self,300,70,50, 
      60,TEAL,[-BASESPEED,BASESPEED])) 
     Quit = False 
     while not Quit: 
      self.surface.fill(BLACK) 
      for b in self.blocks: 
       b.move() 
       b.draw() 
      pygame.display.update() 
      time.sleep(0.02) #import what for this? 
      for event in pygame.event.get(): 
       if event.type == QUIT: 
        Quit = True 
# set up the colors 
BLACK = (0, 0, 0) 
RED = (255, 0, 0) 
GREEN = (0, 255, 0) 
BLUE = (0, 0, 255) 
PURPLE= (200,0,200) 
TEAL = (0,200,200) 

BASESPEED = 2 
# set up pygame 
pygame.init() 

win = BlockWindow(800,800,'Animation with Objects') 

pygame.quit()
