Build XR lessons in Unity, one tool at a time

The ALF tools set up scenes, buttons, moving parts and lesson steps for you. Each guide is short and assumes no Unity experience.

Start with the Unity basicsRead the introduction

Building a lesson, in order​

  1. Create the scene

    A new lesson scene in VR or AR, with the player already set up.

    Scene Generation

  2. Add what learners work with

    Models, buttons, moving parts and machines that come apart.

    Object Spawner, Button Injection, Kinematic Editor Tool, Exploded View

  3. Line it up with a real object

    AR only: printed QR codes place the model on the real machine.

    Positioning Setup

  4. Build the lesson steps

    Instructions, changes in the room, and how each step finishes.

    Scenario Setup, XR Pre-Training

  5. Add it to the start menu

    One button per lesson, opening it with the right setup.

    Main Menu Setup

All tools​

In Unity, every tool is in the top menu under ALF.

Scene Generation
Creates a new lesson scene, in VR or AR, with the player set up.
Main Menu Setup
Builds the start menu, with one button per lesson.
Scenario Setup
Builds the lesson as a series of steps.
XR Pre-Training
Adds a warm-up so learners practise the XR controls first.
Guidance Setup
A simpler Scenario Setup: instruction panels only.
Button Injection
Adds pressable buttons to a machine, or anywhere in the room.
Model Adjuster
Turns, resizes and sets a model on the ground before you place it.
Object Spawner
Puts a model into the scene and decides whether learners can pick it up.
Exploded View
Pulls a machine apart into its pieces, and puts it back together.
Kinematic Editor Tool
Makes parts slide, swing or spin, with buttons to control them.
Part Palette
A board of small parts. Poking one gives the learner the real part.
YouTube Player
Adds a video screen that stays in the room.
Graphs
Turns a CSV file or formulas into a chart in the room.
Syntax Highlighter
Shows program code on a board, coloured like in a code editor.
Motion
Records how you operate a machine and replays it as ghost hands.
Planetary Lab
A falling-objects experiment on Earth, the Moon or Mars.
Electric Field
An electrostatics experiment with charges, field lines and a probe.
Mesh Deformation
A bending lab: how a beam bends and where it is under stress.
Positioning Setup
AR only: lines up a 3D model with a real object using QR codes.
Text Import & Export
Translate or reword all texts of a lesson in one file.
Utilities
Scene Check and Project Status: check the scene and project settings.
