Programming AI - Cars

This AI system is configured thanks to Unity's nav mesh.

The routes are randomised once the car is instantiated. Previously these routes are saved in a list through a script and the cars always have a reference of the possible routes.

the junction is the only one where the two lanes coexist.

Script for a Checkpoint GameObject

Raycast Script

We have two lanes and cars always drive on the right, so at every crossing they have to change the area where they can go and where they cannot go.
