使用教程
三分钟上手：选场景、填参数、投屏全屏。本页汇总最常见的使用方法与现场排错技巧。 Up and running in three minutes: pick a scene, fill in settings, cast fullscreen. This page collects the most common usage tips and on-site troubleshooting.
一、快速开始1 · Quick start
第 1 步：选择场景并填写Step 1 · Pick a scene and fill it in
在控制台（打开工具）选择场景页，填写倒计时、名单、图片/视频等参数，也可直接套用快速模板一键配好。 In the control panel (Open the tool) pick a scene page and fill in settings (countdown, name list, media), or apply a quick template in one click.
第 2 步：打开大屏窗口Step 2 · Open the display window
点击「打开大屏窗口」，浏览器会新开一个纯展示窗口。把它拖到投影仪对应的屏幕，按 F 或点 ⛶ 进入全屏。 Click “Open display window” — a separate display-only window opens. Drag it onto the projector screen and press F or ⛶ for fullscreen.
第 3 步：活动中实时控制Step 3 · Control live during the event
活动进行中，在控制台切换场景、开始倒计时、抽奖 / 转盘、计分、发弹幕。两端通过本地实时同步，大屏即时跟随。 During the event, switch scenes, start the countdown, run the draw/wheel, keep score and send danmaku. Both windows sync locally in real time.
二、投屏到投影仪 / 电视2 · Cast to a projector / TV
- HDMI 有线（最稳）：笔记本用 HDMI 连接投影仪/电视，显示设置选「扩展这些显示器」；把「大屏窗口」拖过去按 F 全屏，声音走 HDMI 输出。HDMI cable (most stable): connect via HDMI, choose “Extend these displays”, drag the display window over and press F; audio travels over HDMI.
- 无线投屏 / 镜像：用系统「投屏 / 无线显示」（Win+K、macOS 隔空播放）或电视自带镜像，把整屏镜像到电视后在本机全屏展示。Wireless / mirroring: use the OS “Cast / Screen mirroring” (Win+K, AirPlay) or the TV's built-in mirror, then go fullscreen here.
- 双屏分工（推荐）：笔记本当控制台，投影仪只显示「大屏窗口」；两端本地同步，你操作、大屏呈现。Dual-screen (recommended): keep the laptop as the control panel, let the projector show only the display window; both stay in sync.
小提示：投屏前先在「主题 / 全局 · 背景」选好配色，并把浏览器缩放调到 100%，大屏 16:9 画面会自动适配分辨率。 Tip: pick your theme/background first and set browser zoom to 100% — the 16:9 stage auto-fits the resolution.
三、场景功能详解3 · Scene guide
倒计时Countdown
三种模式任选：目标时间（定在几点几分）、时长（如 10 分钟）与正计时。天 / 时 / 分 / 秒 / 毫秒可分别开关，四种数字样式一键切换；可设置结束音效、结束弹窗与最后 10 秒提醒，适合开场倒计时与环节计时。 Three modes: target time, duration (e.g. 10 minutes) or count-up. Toggle day/hour/minute/second/millisecond, pick one of four digit styles, and set end sound, end popup and last-10-second cues — great for openings and segment timing.
现场抽奖Lucky draw
把名单粘贴进文本框，或导入 TXT / CSV 文件；设置奖项名称与每个奖项的人数，点击开始后名单滚动，回车或点击停下开奖。已中奖者自动去重，可「撤销本轮」重抽，中奖记录随时导出。还支持照片名单：图片文件名即姓名，大屏滚动头像开奖，中奖记录与结果图自动附带头像。 Paste the list or import TXT / CSV; set prize names and winner counts, then start the scroll and press Enter or click to stop.

Rim, pointer, hub and colors are all customizable with one-click presets; photo lists show avatars on sectors.
红蓝计分板Scoreboard
填入两队队名与获胜分数即可开赛：控制台点按钮加减分，也可以直接用键盘 A/Z、B/N、X 快捷操作；先达到获胜分数的一方自动高亮庆祝，适合团建拓展与游戏分组对抗。 Enter both team names and a winning score to start: add or subtract from the control panel or with keys A/Z, B/N and X; the first side to reach the winning score lights up automatically — perfect for team building and game PKs.
现场投票Live poll
录入多个选项或对战双方（最多 16 项），控制台逐项一键计票，大屏以彩色动画条实时展示票数、占比与总票数，适合现场评选、人气 PK 与表决环节。 Add options or rivals (up to 16), tally each with one click from the panel, and the big screen shows animated bars with counts, shares and totals live — ideal for awards, popularity PKs and votes.
