Worlds Unbound | Annabelle Wright

Overview

Worlds Unbound is a passion project years in the making—an isometric world-building sandbox where players create, script, and share their own virtual worlds. I built everything from scratch: a full world editor, a custom scripting language with its own compiler pipeline, and a multiplayer system with client-side prediction and server reconciliation.

Key Features

Isometric World Editor: Comprehensive tools for placing floors, walls, items, portals, and defining regions. Build everything from cozy homes to sprawling dungeons.
Fabrication Scripting Language: A custom natural-language-inspired programming language with a full compiler pipeline. Script NPCs, create interactive objects, and bring your worlds to life.
Hub-and-Spoke Multiplayer: Scalable architecture where players can host their own worlds while connecting to a central hub for discovery and social features.
12-Layer Character Customization: Deep character creation with 12 distinct customization layers, from body type to accessories and clothing.
Hotbar Inventory System: Intuitive inventory management with full Fabrication integration, allowing scripted items and tools.

Fabrication: The Scripting Language

I built Fabrication from scratch—a natural language-inspired scripting language with its own lexer, parser, and interpreter. Here's what it looks like:

protocol "locked_door" {
  when architect enters tile (5, 10)
    and architect carries item "golden_key"
  then
    show message "The door unlocks!" to architect
    remove item "golden_key" from architect
    teleport architect to (5, 15)
}

protocol "welcome_back" {
  when architect joins
    and persistent architect_variable "has_visited" == true
  then
    show message "Welcome back, friend!" to architect
}

Features include triggers, conditions, multiple variable scopes (world, player, tile, persistent), conditionals, reusable behaviors with parameters, and math expressions.

Technical Highlights

Custom Compiler Pipeline: Lexer, parser, and interpreter for Fabrication, all implemented in GDScript
Event Bus Pattern: Clean, decoupled architecture for handling game events across systems
Position Interpolation: Smooth networked movement with client-side prediction and server reconciliation
JSON Persistence: Flexible save system storing worlds, characters, and scripts in human-readable format
ENet Networking: Reliable UDP networking for responsive multiplayer gameplay
