Minecraft (Java / Paper)
Minecraft is Lanzinha's flagship game. Worlds run on a Java server engine — Paper by default — are world-backed, and connect on the standard Java port. You can attach content (plugins, mods, datapacks, and resource packs) to make the server your own.
- Which engine (Paper / Fabric / Forge) a world runs, and how to pick it
- The Minecraft versions available and how version pinning works
- The per-room settings (difficulty, game mode, whitelist, online-mode, and more)
- What content you can attach, and how saves and content data are kept
Engine (Paper / Fabric / Forge)
Every Minecraft world runs one engine, chosen when you create the world (next to the version). The engine decides what kind of content the world can run:
| Engine | Runs | Notes |
|---|---|---|
| Paper (default) | Bukkit/Spigot plugins | The classic, lightweight choice |
| Fabric | Fabric mods | Lightweight modding |
| Forge | Forge mods | The big modpack ecosystem |
The engine is fixed for the life of the world — to switch engines, create a new world with that engine selected. The engine selector only appears for versions that ship with the engine baked in; today Fabric and Forge are available on the recommended version (1.21.11), and older versions are Paper-only.
Plugins need a Paper world; mods need a Fabric or Forge world. You can't mix plugins and mods on the same world, and a Fabric mod won't run on a Forge server (or vice versa). Pick the engine that matches the content you plan to attach.
Versions
Lanzinha runs a fixed, pinned list of versions baked into the server image:
| Version | |
|---|---|
| 1.21.8 | |
| 1.21.9 | |
| 1.21.10 | |
| 1.21.11 | Recommended (default) |
You pick the version when you create the world, and every room you open against that world inherits it — so a save can never be opened on an incompatible version. To use a different version, create a new world with that version selected.
Room settings
When you open a Minecraft room you can set:
- Server name (MOTD) — shown in the multiplayer list. Defaults to
"<world>'s room". - Max players — up to 20.
- Difficulty — peaceful, easy, normal, or hard.
- Game mode — survival, creative, or adventure.
- Online-mode — on by default, so only official (Mojang/Microsoft) accounts can connect; turn it off to let launchers like TLauncher and other cracked clients join.
- Whitelist — on/off, plus the list of allowed players (add your friends' usernames).
- Operators (ops) — players granted admin, with an op level (0–4).
- View / simulation distance — 2–32 chunks.
Settings are re-applied every time the room boots, so changing difficulty, the MOTD, or the whitelist simply takes effect the next time you start the room.
Content
Make the server yours by uploading content from your world (in Worlds):
| Content | Engine | What it does |
|---|---|---|
| Plugins | Paper | Server-side .jar add-ons (Bukkit/Spigot) |
| Mods | Fabric or Forge | Server-side .jar mods (new blocks, items, mechanics) |
| Datapacks | Any | Data-only .zip (functions, recipes, loot) |
| Resource packs | Any | Client-side .zip, handed to players on join |
Datapacks and resource packs are available to everyone. Plugins and mods run real code on the server, so Lanzinha runs them in a hardened sandbox; the feature is advanced and may not be enabled on your account yet while it rolls out — check support if you don't see it.
Connecting
The server listens on TCP 25565 (the default Java port), so players can usually just enter the address with no port. RCON is enabled locally for the server only and is never exposed publicly. See Connecting to your server.
How your save is kept
When a room stops, Lanzinha snapshots world/, world_nether/, and world_the_end/ —
your Overworld, Nether, and End. Server config (difficulty, whitelist, etc.) is not part of
the snapshot; it's re-rendered from your room settings on each boot.
Content data is kept too. Plugin and mod generated data — economy balances, permissions
(such as LuckPerms), land claims, and per-plugin config you edited in-game — is backed up with
the world and persists across sessions. The plugin and mod .jar files themselves are
re-applied from your uploads on every boot, so to update one, just re-upload the new .jar
(the world keeps its data). Datapacks live inside the world and persist automatically.
