爲什麼我的pygame sprites不能獨立移動？我如何讓他們獨立移動？

Question

只有一個蘭花精靈，它或多或少地按照我的意圖反彈屏幕。當我補充更多的時候，蘭花精靈會作爲一個整體一起移動，並且從邊界反彈，即使它們沒有接近接觸它。這裏是代碼：

#Import and Init 
import pygame 
import random 
from pygame.locals import * 
pygame.init() 

#Set Up the Window 
width = 1240 
height = 700 
screen = pygame.display.set_mode((width, height)) 
pygame.display.set_caption("Pollination!") 

background = pygame.Surface(screen.get_size()) 
background = pygame.image.load("Forrest.jpg") 
background = background.convert() 

#Load and Convert the wasp 
wasp = pygame.sprite.Sprite() 
wasp.image = pygame.image.load("wasp1.gif") 
wasp.rect = wasp.image.get_rect() 
wasp_group = pygame.sprite.GroupSingle(wasp) 

flowers = pygame.sprite.OrderedUpdates() 

for i in range(5): 
    orchid = pygame.sprite.Sprite() 
    orchid.image = pygame.image.load("orchid1.gif") 
    orchid.rect = orchid.image.get_rect() 
    orchid.rect.right = random.randint(0, 1240) 
    orchid.rect.top = random.randint(0, 700) 
    flowers.add(orchid) 

buzz = pygame.mixer.Sound("buzz.wav") 
#Clock and Loop Variables 
framerate = pygame.time.Clock() 
GameGo = True 

orchid_xinc = 2 
orchid_yinc = 2 

wasp_move = 5 
#The Main Loop 
while GameGo: 

    #Tick the Clock 
    framerate.tick(60) 

    #Keyborad Keypress Events, Movement 

    if pygame.key.get_pressed()[K_UP]: 
     wasp.rect.top -= wasp_move 
     if wasp.rect.top < -30: 
      wasp.rect.top = -30 
    if pygame.key.get_pressed()[K_DOWN]: 
     wasp.rect.top += wasp_move 
     if wasp.rect.top > 625: 
      wasp.rect.top = 625 
    if pygame.key.get_pressed()[K_LEFT]: 
     wasp.rect.right -= wasp_move 
     if wasp.rect.right < 110: 
      wasp.rect.right = 110 
    if pygame.key.get_pressed()[K_RIGHT]: 
     wasp.rect.right += wasp_move 
     if wasp.rect.right > 1255: 
      wasp.rect.right = 1255 

    for orchid in flowers: 
     if orchid.rect.top < -30: 
      orchid_yinc *= -1 
     if orchid.rect.top > 625: 
      orchid_yinc *= -1 
     if orchid.rect.right < 110: 
      orchid_xinc *= -1 
     if orchid.rect.right > 1255: 
      orchid_xinc *= -1 

     orchid.rect.right += orchid_xinc 
     orchid.rect.top -= orchid_yinc 

    for orchid in pygame.sprite.groupcollide(wasp_group, flowers, False, True): 
     buzz.play() 
## #Blit our Images 
    screen.blit(background, (0, 0)) 
    flowers.draw(screen) 
    wasp_group.draw(screen) 
    pygame.display.update() 


    #Handle a Close Event 
    for event in pygame.event.get(): 
     if event.type == pygame.QUIT: 
      GameGo = False 

pygame.quit()

也許它的事實，你在for循環中鍵入「蘭花_ ####」，更新每個蘭花。如果在你的蘭花類中，init方法定義了一個self。####，因爲它應該用「Object。####」調用，而不是下劃線。如果我錯了，請檢查「flowers.draw」函數，確保它使用各自的座標繪製所有的蘭花。
