我制作了一個帶有多個下落立方體的小游戲，玩家（正方形）必須避開它。我設法使碰撞起作用，但問題是每次圓形和正方形碰撞時，每次碰撞時都會顯示文本。但我希望當圓形和方形第一次發生碰撞時，文本會繼續顯示。有什么辦法嗎？import pygamefrom pygame.locals import *import osimport randomimport mathimport sysimport timewhite = (255,255,255)blue = (0,0,255)gravity = 10size =10height = 500width =600varHeigth = heightballNum = 5eBall = []apGame = pygame.display.set_mode((width, height))pygame.display.set_caption("AP Project")clock = pygame.time.Clock()class Player(object):  def __init__(self):    red = (255, 0, 0)    move_x = 300    move_y = 400    self.rect = pygame.draw.rect(apGame,red, (move_x, move_y, 10, 10))    self.dist = 10  def handle_keys(self):    for e in pygame.event.get():      if e.type == pygame.QUIT:        pygame.quit();        exit()    key = pygame.key.get_pressed()    if key[pygame.K_LEFT]:      self.draw_rect(-1, 0)    elif key[pygame.K_RIGHT]:      self.draw_rect(1, 0)    elif key[pygame.K_ESCAPE]:      pygame.quit();      exit()    else:      self.draw_rect(0, 0)  def draw_rect(self, x, y):    red = (255, 0, 0)    black = (0, 0, 0)    '''apGame.fill(black)'''    self.rect = self.rect.move(x * self.dist, y * self.dist);    pygame.draw.rect(apGame, red , self.rect)    pygame.display.update()  def draw(self,surface):    red = (255, 0, 0)    move_x = 300    move_y = 400    pygame.draw.rect(apGame, red, (move_x, move_y, 10, 10))#The game over text here def show_go_screen():  pygame.font.init()  myfont = pygame.font.SysFont("Comic Sans MS", 30)  label = myfont.render("Game Over", 1, red)  apGame.blit(label, (300,100))def instuct():  pygame.font.init()  myfont = pygame.font.SysFont("Comic Sans MS", 15)  label = myfont.render("Avoid The Circles", 1, red)  apGame.blit(label, (250,450))
