Examples

Learn HoloScript through practical examples. All code is copy-paste ready.

Basic Examples

Hello World

Your first HoloScript program - a glowing greeting orb.

Interactive Cube

A grabbable, throwable cube with physics.

VR Controller Demo

Respond to VR controller input — triggers, thumbsticks, haptics.

Intermediate Examples

Inventory System

Draggable items, slots, and equipment.

Physics Playground

Balls, ramps, Newton's Cradle, and dominos.

Multiplayer Sync

Networked objects and state synchronization across players.

Advanced Examples

Complete Game: Arena

A full VR battle arena in ~100 lines.

AI Integration

Use MCP server (34+ tools) for AI-generated content.

Multi-Platform Export

Compile to 18+ targets: Unity, Unreal, Godot, VRChat, Babylon, WebGPU, visionOS, Android XR, and more.

Cross-Domain Examples

Robotics (URDF/SDF)

Compile HoloScript scenes to URDF for ROS 2 robots or SDF for Gazebo simulation.

Digital Twins (DTDL)

Define IoT digital twins that compile to Azure DTDL interfaces.

IoT Interop (W3C WoT)

Export scene objects as W3C Web of Things Thing Descriptions for IoT device interop.

OpenUSD Pipeline

Compile scenes to USDA for the Pixar/Apple/NVIDIA OpenUSD ecosystem.
