About this mod Author’s original text

On-Together School Screen

Press F9 to open the menu.

Windows mod that plays shared YouTube videos on the whiteboard inside the school building.

Features

  • Uses a purple library-style F9 menu with Now playing, Lobby queue, Playlists, and Access tabs.
  • Finds the school's DrawingBoard and displays a local Chromium-based Microsoft Edge WebView2 player on it.
  • Lets any player with the mod add videos and start the queue when the board is idle. The game host does not need the mod.
  • Automatically plays the next queued video when the current video finishes, in queue order.
  • Sends playback and queue updates through the school's networked whiteboard RPC. It does not send synchronization text through chat.
  • Displays the playing video's title in the panel and resolves queue entries to video titles.
  • Shows video thumbnails, titles, available durations, and the person who added each queued video.
  • Saves private playlists on your computer so you can queue saved videos directly from F9, individually or as a selection.
  • Limits additions to three waiting videos per person and ten seconds between accepted additions by default. A modded game host can adjust these limits in Access.
  • Lets modded players vote to skip; the vote passes at 30% of active modded players, rounded up with at least one yes vote. The game host can skip immediately if they have the mod.
  • Gives a modded game host an Access tab to block specific players from adding videos to the queue.
  • Clears playback, queue, votes, and queue blocks when the lobby changes.
  • Keeps the hidden browser helper out of Alt+Tab while it renders the whiteboard video.
  • Gives each player an independent volume control with distance falloff, a 0–200% slider, and mute.
  • Loads video and audio locally for each player; video frames are not sent over the game network.
  • Targets a 30 FPS whiteboard refresh while the game can keep up.
  • Shows a color-changing, bouncing DVD-style logo behind the F9 prompt while the board is waiting for a video.
  • Celebrates a DVD corner hit with a brief visual effect.

Install

Download the ZIP from GitHub Releases.

Mod manager

Install through Mod Manager or r2modman. For a local ZIP, use the manager's Import local mod option and choose the package. The manager installs the mod files together under its profile's BepInEx/plugins folder.

Manual installation

  • Close On-Together before replacing the mod files.
  • Install BepInEx for On-Together and the Microsoft Edge WebView2 Runtime.
  • Extract the ZIP and copy its BepInEx folder into the game folder or the manager's profile folder. The package places the plugin, browser helper, WebView2 DLLs, and www folder together inside BepInEx/plugins. For manual updates, replace your previous School Screen installation with these files so only one copy of the plugin is loaded. The www folder must stay beside SchoolScreenBrowser.exe.
  • Everyone who wants to watch together should install version 0.1.12 and enter the school. Press F9 to open the controls. The host does not need the mod for playback, queueing, or skip voting. Adding a video starts playback when the board and queue are empty; otherwise it adds to the end of the queue. Videos advance automatically when they finish. If the board is stopped with videos still queued, anyone can press Play Next in the Queue tab to start the first entry.

Updating from an older version

Upgrade to 0.1.12 and replace your previous School Screen files. All modded viewers in the lobby should update together so queue confirmations and selected-playlist requests work consistently.

Version 0.1.11 removes a player-discovery message that older versions sent through the game's report-player system. That message could repeatedly open a Kick Player? dialog on a host without the mod. All School Screen users in the lobby should update to 0.1.12; clients older than 0.1.11 can still cause these dialogs.

If a host already has these dialogs, everyone using an older version should leave the

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
  3. For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
  4. Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.

Install locations vary a lot between mods — the bundled readme is the most reliable guide.
