使用pygame创建滑块

import pygame
from pygame.locals import *

pygame.init()

screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("滑块示例")

slider_width = 200
slider_height = 20
slider_color = (255, 255, 255)
slider_x = (screen_width - slider_width) // 2
slider_y = (screen_height - slider_height) // 2

slider_rect = pygame.Rect(slider_x, slider_y, slider_width, slider_height)

pygame.draw.rect(screen, slider_color, slider_rect)
pygame.display.flip()

running = True
while running:
    for event in pygame.event.get():
        if event.type == QUIT:
            running = False
        elif event.type == MOUSEBUTTONDOWN:
            if event.button == 1:  # 左键按下
                if slider_rect.collidepoint(event.pos):  # 判断鼠标点击位置是否在滑块上
                    dragging = True
        elif event.type == MOUSEBUTTONUP:
            if event.button == 1:  # 左键释放
                dragging = False
        elif event.type == MOUSEMOTION:
            if dragging:
                slider_rect.centerx = event.pos[0]  # 拖动滑块时更新滑块的位置
    screen.fill((0, 0, 0))  # 清空屏幕
    pygame.draw.rect(screen, slider_color, slider_rect)  # 重新渲染滑块
    pygame.display.flip()  # 更新屏幕显示

pygame.quit()
