FAMILY MINECRAFT · SERVER VERSION 0.4.1
Download once. Click Play.
One loader takes care of Prism, the right profile, Java and the mods. Keep the same profile when the server updates.
Download Windows loaderStart playing
- Download the loader, right-click the ZIP and choose Extract All.
- Close Minecraft and Prism, then double-click Play.cmd. Choose a server and click Update & Play.
- Use the Schema Builder Play desktop shortcut from then on. It checks for updates before every launch.
Live and Beta use your own Minecraft Java account. Sign in inside Prism when asked. Offline test uses a different test name on each PC. Joining requires the home LAN.
Your existing settings, worlds and profiles are kept. If old Schema Builder profiles no longer match a supported server, the loader lists them and asks before removing them from Prism. Confirmed removals are archived for recovery.
The launcher checks for an existing Prism installation and reuses your matching profile. If Prism lives in a custom portable folder, use Browse to select it before starting.
First setup can take a few minutes while official tools and game files download. A failed update stops the launch and shows the error; keep the profile and retry.
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.
Technical details and recovery
Minecraft Java 1.21.1 · NeoForge 21.1.256 · Java 21. Live :25565 and authenticated Beta :25566 include Modern Companions 4.65. Offline test :25567 is separate.
The loader verifies SHA-256, downloads only changed mods, and stores replaced JARs outside the mods folder. Accounts stay in Prism. Archives are kept under %LOCALAPPDATA%\SchemaBuilder\archived-instances, or beside Prism's instances folder when it lives on another drive. The loader prints the location; close Prism and move an archived profile back to its original instance directory to restore it.
Use the server selector in the launcher to change the remembered server. Game/loader migrations remain explicit compatibility checks. Windows 10/11 x64.
