for plant in plant_list:
if isinstance(plant, Sunflower):
plant.produce_sunshine()
elif isinstance(plant, PeaShooter):
plant.shoot()
plant.update()

更新僵尸

for zombie in zombie_list:
zombie.move()

更新子弹

# 绘制僵尸
for zombie in zombie_list:
zombie.display()
# 绘制子弹
for bullet in bullet_list:

sunshine_text = font.render(f"阳光: {sunshine}", True, (255, 255, 0))
screen.blit(sunshine_text, (10, 10))

控制帧率

clock.tick(30)
pygame.display.flip()

pygame.quit()
sys.exit()
