OneBlock By Isi

OneBlock (NeoForge 26.1.1)

OneBlock by Onkel_isi is a multiplayer-ready OneBlock mod built for Minecraft Java 26.1.1 (NeoForge). Designed from the ground up for both solo play and multiplayer servers, it combines a built-in Void world preset, automatic island claiming, 18 themed progression stages with endless Prestige loops, Lucky Events, custom loot chests, and 18 balanced survival recipes.

Key Features

Void World Preset & Multi-Island Layout

• Built-In Void World Preset (oneblock:void): Select OneBlock Void World directly under More World Options → World Type in singleplayer, or set level-type=oneblock:void in server.properties for an empty Void Overworld with normal Nether and End dimensions.
• Configurable Multi-OneBlock Grid or Line: Generates 10 OneBlocks spaced 30 blocks apart by default (LINE or GRID layout). Server owners can adjust island count (1–250), spacing (8–1000), and coordinates in oneblock-server.toml and apply changes on restart or via /oneblock reload without wiping existing island progress.
• 10-Block Proximity Glow: Each OneBlock renders a subtle, stage-colored pulsing outline and particle effect exclusively when a player is within 10 blocks (configurable).

Seamless Multiplayer Onboarding & Protection

• Automatic First-Join Assignment: New players joining the server for the first time are automatically assigned the next available OneBlock, claim ownership of it, receive a 3×3 oak safety platform underneath, and spawn directly on top.
• Safe Respawning: Players without a custom bed automatically respawn safely on their claimed OneBlock.
• Grief Protection & Friend Sharing: Claimed OneBlocks can only be mined by their owner and trusted friends (/oneblock trust).

Real-Time Progress Tracking

• Instant ActionBar & BossBar Feedback: Punching (Left-Click) or mining a OneBlock immediately displays a 20-segment progress bar in the ActionBar alongside an optional proximity BossBar showing the current stage, Prestige loop count, and remaining blocks.
