NullServers — Expanded Multiplayer, Building & Custom Content for Slendytubbies 3

[Nullframe Collective]

Hey everyone!

We'd like to share NullServers, our multiplayer mod for Slendytubbies 3.

We've been working on giving players more control over their rooms, expanding Sandbox, and bringing custom content into multiplayer. You can build things with friends, experiment with the world, play custom maps and modes, or just throw each other around.

What can you do?

• Create rooms for up to 50 players.
  Set your room's player limit and bring a bigger group together. Actual performance depends on the host, connection, and what's happening in the room.
  
  
• Manage your room in-game.
  Change room settings, manage players, and grant administrative access without leaving the game.
  
  
• Build together.
  Spawn objects, move and rotate them, enter custom scale values, and select multiple objects to edit them together. Building works with empty hands.
  
  
• Grab and throw things.
  Carry props and ragdolls. With the host's “Throw Any One” setting enabled, you can also grab and throw living players and NPCs.
  
  
• Experiment with the world.
  Adjust map scale, rotation, gravity, and environmental settings. You can also use an image URL for a custom skybox shared with the room.
  
  
• Customize your character.
  Use custom nicknames, colors, and expanded appearance options, including multiple hat slots on Nullframe servers.
  
  
• Use proximity voice chat.
  Our optional VoiceChat addon adds spatial push-to-talk audio, speaking indicators, microphone selection, gain adjustment, and a configurable talk key.
  

Protection & moderation

• Community-wide blacklist.
  NullServers checks our shared blacklist on both the joining client and the room host. Bans are checked against the ZeoWorks account identity, rather than the custom nickname selected in the lobby.
  
  
• Built-in Anti-Crash protection.
  NullServers includes checks designed to reject malformed or abusive network messages and reduce the risk of crashes caused by malicious clients. Protection runs automatically, with blocked-message and removal counters available in Server Settings.
  

Custom content & frameworks

NullServers integrates with our content frameworks:

• CustomWeaponsFramework
  
• CustomPlayerCustomization
  
• CustomNPCFramework
  
• CustomGameModesFramework
  
• CustomMapsFramework
  

These let creators bring their own weapons, cosmetics, NPCs, game modes, and maps into our multiplayer rooms.

The frameworks are optional. You can use NullServers without installing all of them. When a room requires content you're missing, the mod shows the required addons and content packs before you join.
