Work still progresses slowly on my ART implementation (more posts will follow), but I decided to quickly look at upgrading the project as Unity 5 released at GDC. One or two minor changes were required with the NavmeshAgent, but otherwise a simple transition.

Previously the option to render shadows had been restricted to Unity Pro licences only – no longer with Unity 5!

As I do not intend to further the graphics of this application, the addition of shadows and new light sources really enhances the scene. The red light here pulses like warning or alarm, while the white light flickers on and off.

The main attraction however was the blue cone light – which nicely represents the A.I.’s cone of vision, with areas in shadow correctly showing blind spots behind obstacles.
