Qtchart 画3D柱状图 代码怎么实现

Sure, 我可以帮你写一个用 pygame 做控制角色移动并跟随鼠标位置的小游戏，以下是代码，你可以参考一下：

import pygame
import math

# 初始化 pygame
pygame.init()

# 定义窗口大小和标题
screen_size = (640, 480)
screen_title = 'Control character movement and weapon orientation'
screen = pygame.display.set_mode(screen_size)
pygame.display.set_caption(screen_title)

# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)

# 加载角色和武器图片
character_img = pygame.image.load('character.png')
weapon_img = pygame.image.load('weapon.png')

# 获取角色和武器图片的大小
character_size = character_img.get_size()
weapon_size = weapon_img.get_size()

# 定义角色坐标（屏幕左上角为(0,0)点）
character_pos = [screen_size[0]/2 - character_size[0]/2, screen_size[1]/2 - character_size[1]/2]

# 定义武器相对于角色的偏移量
weapon_offset = [character_size[0]/2 - weapon_size[0]/2, character_size[1]/2 - weapon_size[1]/2]

# 定义武器坐标
weapon_pos = [character_pos[0] + weapon_offset[0], character_pos[1] + weapon_offset[1]]

# 定义武器旋转中心
weapon_center = (weapon_size[0]/2, weapon_size[1]/2)

# 定义武器指针方向
weapon_direction = 0

# 定义角色速度
character_speed = 5

# 开始游戏主循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 获取鼠标位置
    mouse_pos = pygame.mouse.get_pos()

    # 计算武器指针方向
    x_dist = mouse_pos[0] - weapon_pos[0] - weapon_center[0]
    y_dist = mouse_pos[1] - weapon_pos[1] - weapon_center[1]
    weapon_direction = math.degrees(math.atan2(-y_dist, x_dist))

    # 绘制背景
    screen.fill(BLACK)

    # 绘制角色和武器
    screen.blit(character_img, character_pos)
    rotated_weapon_img = pygame.transform.rotate(weapon_img, weapon_direction)
    rotated_weapon_pos = (character_pos[0] + weapon_offset[0], character_pos[1] + weapon_offset[1])
    screen.blit(rotated_weapon_img, rotated_weapon_pos)

    # 计算角色移动距离
    keys = pygame.key.get_pressed()
    move_dist = [0, 0]
    if keys[pygame.K_LEFT]:
        move_dist[0] -= character_speed
    if keys[pygame.K_RIGHT]:
        move_dist[0] += character_speed
    if keys[pygame.K_UP]:
        move_dist[1] -= character_speed
    if keys[pygame.K_DOWN]:
        move_dist[1] += character_speed

    # 更新角色坐标和武器坐标
    character_pos[0] += move_dist[0]
    character_pos[1] += move_dist[1]
    weapon_pos[0] += move_dist[0]
    weapon_pos[1] += move_dist[1]

    # 更新屏幕
    pygame.display.flip()

# 关闭 pygame
pygame.quit()
