Introduction to HoloScript

HoloScript is a full programming language for VR, AR, robotics, IoT, and digital twins. It compiles to 25+ targets including Unity, Unreal, Godot, visionOS, Android XR, WebGPU, URDF (ROS 2), SDF (Gazebo), DTDL (Azure Digital Twins), W3C WoT, and OpenUSD — from a single source file.

🚀 Start with Studio (Recommended)

No coding required! HoloScript Studio is a web-based IDE powered by Brittney AI that lets you build VR scenes using natural language.

Why HoloScript?

For Humans

• No syntax errors - Visual/declarative approach eliminates brackets and semicolons
• Universal input - Voice, gesture, gaze, or traditional keyboard
• See the data flow - Watch computation happen in 3D space

For AI

• Visual understanding - AI "sees" program structure
• Native manipulation - AI can place and connect objects naturally
• Any output target - Generate code for any platform

For Computing

• One source → 18+ targets - Unity, Unreal, Godot, VRChat, Babylon.js, WebGPU, visionOS, Android XR, URDF, SDF, DTDL, WoT, OpenUSD, Three.js, GLTF, OpenXR, iOS, WASM
• 50,000 → 500 lines - Declarative syntax eliminates boilerplate
• Cross-domain - VR, AR, robotics, IoT, and digital twins from one source
• Dual parser - TypeScript + Rust/WASM with full LSP, linter, and formatter

File Formats

HoloScript uses three file formats:

Extension	Purpose	Best For
.hs	Classic HoloScript	Simple prototypes, learning
.hsplus	HoloScript Plus	VR traits, networking, physics
.holo	Composition	AI-generated scenes, full worlds

Quick Start

Install the VS Code extension:

ext install holoscript.holoscript-vscode

Create your first scene:

composition "Hello World" {
  environment {
    skybox: "gradient"
    ambient_light: 0.5
  }

  object "Cube" {
    @collidable
    position: [0, 1, -3]
    color: "#00ffff"
  }
}
