鼠标悬停在按钮上时调整按钮大小

Question

我试图让按钮在鼠标悬停在它上面时做出反应。我想让它稍微调整一下大小，所以我在 Pygame、Python 中给出了一个按钮效果。

rock_img = pygame.image.load('assets/rock_btn.png').convert_alpha()
scissor_img = pygame.image.load('assets/scissor_btn.png').convert_alpha()

paper_img = pygame.image.load('assets/paper_btn.png').convert_alpha()

ROCK = rock_img
SCISSOR = scissor_img
PAPER = paper_img

rock_button = button.Button(85, 50, rock_img, 0.1)
scissor_button = button.Button(90, 390, scissor_img, 6)
paper_button = button.Button(90, 230, paper_img, 7)

running = True
while running:

      pygame.draw.line(screen, (0,0,0),
                      [295, 0],
                      [295, 500], 5)
      pygame.display.update()

      if rock_button.draw(screen):
         print('Rock')
      if scissor_button.draw(screen):
         print("Scissor")
      if paper_button.draw(screen):
         print('Paper')

      for event in pygame.event.get():
        if event.type == pygame.QUIT:
          running = False
  
      pygame.display.update()
pygame.quit()
