The public downloads are at https://minecraft.dokinetix.com/. Joining requires the home LAN. All three servers use the same 0.4.1 mod, with separate profiles, ports and authentication.
Download live Prism profile 0.4.1Update & Play helpersBeta / account-free testInstall Modern Companions 4.65 once for live and authenticated beta. The existing Update & Play helper updates Schema Builder; companion setup is separate.
Import and play
- Install Prism Launcher. Select Java 21 or Prism's automatic Java download.
- Choose Add Instance → Import and select the matching clean ZIP. Prism downloads upstream game/loader/runtime files. Sign in through Prism using your own account with Minecraft Java Edition access; each simultaneous player needs their own account.
- Launch and choose the saved server
192.168.2.149:25565. Keep separate live and beta profiles.
Existing profiles: update before launch
Close Minecraft, Prism and Java applications. Install the new Update & Play 1.1 kit once: extract over your existing helper folder and replace shipped scripts, keeping live.settings.json and beta.settings.json. Then use the matching channel shortcut. Version 1.0 beta helpers reject the promoted stable version and must be replaced. Saved channel bindings stay in place.
The original generic live updater remains available and checks root latest.json. It is for the live profile only.

Account-free offline beta
Port 192.168.2.149:25567 uses test identities without Microsoft sign-in. Download the complete offline 0.4.1 test and update kit. For an existing extraction, back it up, close Java, and extract the new kit into that SAME folder replacing shipped files. Keep .tools, build, run and the downloaded Gradle wrapper JAR. Use Update & Play-Beta.cmd: it first backs up old shipped mod JARs/state, then updates and launches. Settings, worlds, downloaded runtime caches and remembered test name remain. Each PC needs a distinct name. A cold first setup downloads pinned official Java/Gradle/game tools and may take several minutes.
Eighteen schematics to throw
| Schematic | Add to one clay brick |
|---|---|
| Stone Archway Schematic | Quartz block |
| Red Barn Schematic | Hay block |
| Footbridge Schematic | Oak planks |
| Timber Cabin Schematic | Birch planks |
| Canvas Campsite Schematic | White wool |
| Garden Courtyard Schematic | Polished andesite |
| Enchanting Library Schematic | Bookshelf |
| Birch Gazebo Schematic | Birch log |
| Glass Greenhouse Schematic | Glass |
| Lookout Hut Schematic | Stone bricks |
| Perfect Home Schematic | Red bed |
| Smelting Lodge Schematic | Blast furnace |
| Open Stable Schematic | Saddle |
| Storage Warehouse Schematic | Chest |
| TNT Cube Schematic | Tnt |
| Village Inn Schematic | Bread |
| Guarded Watchtower Schematic | Cobblestone |
| Brick Workshop Schematic | Crafting table |
All eighteen recipes are automatically known on the family servers. Names now say Schematic in the mod; search for schematic. The historical twelve-name resource pack is optional and unnecessary for this release.
Right-click to throw. The front faces back toward you at your nearest cardinal heading when thrown. Pitch and turning afterward do not change it. The original bridge runs across your throw direction. Use open space: structures replace their entire construction volume.
Perfect Home, golem, trains and TNT
Perfect Home has three floors, four bedrooms, shared storage, smelting and enchanting. It includes torches and complete doors; keep the entrance and stair landings clear.
Use the Netherite Golem Spawn Egg from the creative inventory to summon the Netherite Golem. It uses iron-golem behavior, protects against hostile mobs and has its own netherite appearance.
Search for Train or open the Schema Builder creative tab for Minecart with Furnace, rails, chains, passenger minecarts, coal and charcoal. Place the furnace engine on rails with a passenger cart. Hold a chain and right-click each cart to couple them. Each survival link consumes one chain; use one furnace engine and at most eight carts. Switch to an empty hand, stop sneaking, then right-click the engine to open its fuel screen and add coal or charcoal. Sit in a linked passenger cart: W accelerates, S slows and Space brakes. Sneak-right-click with an empty hand disconnects and returns the chain. Use /trainhelp for these controls. Build complete clear rails and begin slowly; derailment can explode and damage nearby builds.
The TNT Cube Schematic builds a solid 20×20×20 cube of 8,000 TNT blocks. Placement does not ignite it. Ignite with normal Minecraft methods only after everyone is clear; the explosion can destroy nearby builds.
For a problem, use /fixitdad what happened, wait for the saved report ID and give that ID to Dad.
Manifests, checksums and limits
Live manifest :25565 · Authenticated beta :25566 · Offline beta :25567 · 0.4.1 mod only · Checksums
The helpers preserve user files, compare SHA-256, back up changed mod JARs and stop before launch on a failed check. They fetch only a tiny manifest when current. Game or loader changes require a new compatible profile. Publication does not update an existing player PC; run the shortcut.
Physical multi-PC import, sign-in, rendering and gameplay acceptance remain separate observations.
