Step 0: From GAMA Model to Virtual Universe

Objectives

This tutorial shows how to build a complete virtual environment with interactions from an existing GAMA model. Starting from the traffic model included in the GAMA model library, vehicles travel on a road network from building to building. The greater the number of vehicles on a road relative to its capacity, the slower the vehicles move along the road. Each vehicle also emits pollutants into the air. The VR version allows you to navigate with a top-down manager's view and to close or open roads.

Requirements

• GAMA 2025.06 with the SIMPLE plugin installed. See GAMA Installation.
• Unity 6000.3.8f1 with Android Build Support. See Unity Installation.
• The WebPlatform running. See Install the WebPlatform.

Steps

1. Step 1 — Generate the VR GAML model — run the SIMPLE wizard in GAMA to scaffold the VR experiment
2. Step 2 — Set up the Unity scene — configure the Unity template to receive traffic model geometry
3. Step 3 — Add interactions — enable players to open and close roads from inside VR
