HoloScript Quick Start Guide

Prerequisites

Before you start, install:

Node.js 18+ - Download here
pnpm - Run npm install -g pnpm after installing Node
Git - Download here

Getting Started (5 minutes)

1. Install

# Clone the repo
git clone https://github.com/brianonbased-dev/Hololand.git
cd Hololand

# Install dependencies
pnpm install

# Build everything
pnpm build

2. Run an Example

# Run the main demo app
cd examples/hololand-central
pnpm dev

Then open http://localhost:5173 in your browser.

3. Try the Playground

cd packages/playground
pnpm dev

Open http://localhost:5173 - write HoloScript code and see it render in real-time!

What is HoloScript?

HoloScript is a language for creating 3D/VR/AR worlds. Two file types:

File	Use	Example
`.hsplus`	Full programming language	Games, multiplayer, physics
`.holo`	Visual/declarative	Simple scenes, prototypes

Hello World (`.hsplus`)

// A simple rotating cube
orb Cube {
  geometry: box(1, 1, 1)
  color: "#3b82f6"
  position: [0, 1, 0]
}

system Spin {
  update(dt) {
    Cube.rotation.y += dt * 0.5
  }
}

Hello World (`.holo`)

orb MyCube
  geometry: box
  color: blue
  position: 0, 1, 0

AI Integration - Quick Reference Guide

What is this? A guide to using AI to build VR/AR worlds. Speak or type what you want, and the AI creates it.

"Create a coffee shop with a fireplace" → Done in 3 seconds

📁 HoloScript File Types

HoloScript has two complementary formats:

Extension	Purpose	Use For
`.holo`	Declarative, visual	World layouts, agents, AI-generated content
`.hsplus`	Imperative, full language	Complex logic, networking, custom systems

📖 See docs/HOLOSCRIPT_FILE_TYPES.md for more details.

🚀 What's New

The AI Bridge client connects to infinityassistant-service at https://infinityservice.io for AI-powered VR creation:

Natural Language → VR: Describe what you want, get interactive 3D VR instantly (powered by infinityservice.io)
Voice Commands: "Create a coffee shop" → renders in WebXR headset (AI translation via infinityservice.io)
AI Avatars: Generate custom avatars from text descriptions (generation via infinityservice.io)
Real-Time Updates: Modify scenes on the fly without reloading

📦 Core Components

CompilerBridge (NEW)

File: packages/ai-bridge/src/CompilerBridge.ts

The integration layer that converts HoloScript/HoloScript+ → React Three Fiber code.

Usage:

import { CompilerBridge } from '@hololand/ai-bridge';

const bridge = new CompilerBridge();

// Compile HoloScript to R3F
const result = await bridge.compile(`
  orb {
    name: "Coffee Shop"
    position: [0, 0, 0]
    entity cup {
      model: "cup.glb"
    }
  }
`);

if (result.success) {
  console.log(result.r3fCode);  // React component code
  console.log(result.metadata); // {zones: 1, entities: 1, handlers: 0, duration: 42ms}
}

Methods:

compile(holoScript) → Compiles HoloScript to R3F
validate(holoScript) → Syntax validation
getMetrics(holoScript) → Performance analysis

🎮 Use Cases

Voice-Driven VR Building

User Voice: "Create a futuristic marketplace"
  ↓
System: Recognizes speech → generates HoloScript
  ↓
System: Compiles to R3F → renders in WebXR headset
  ↓
Result: Interactive VR scene appears instantly

AI Avatar Generation

Text: "Create a friendly AI assistant with glowing blue eyes"
  ↓
System: Generates HoloScript avatar definition
  ↓
System: Compiles with VRM model support
  ↓
Result: Custom avatar with animations and expressions

Real-Time Scene Editing

Command: "Add a dancing floor tile"
  ↓
System: Updates HoloScript
  ↓
System: Recompiles only changed parts
  ↓
Result: Scene updates instantly without reload

📊 Performance

Compilation Time: 30-60ms for typical scenes
Memory: ~50MB for loaded modules
Bundle Size: CompilerBridge adds <20KB gzip
Complexity: O(n) where n = lines of HoloScript
