preik.net - Unity3D Page

On this page I'll post tutorials or files etc that I make related to Unity3D. Unity3D is a game engine which provides a way to (fairly) simply make and publish your own 3D games (to a browser, or to Windows/Mac etc). It's kind of like Gamemaker (I think at yoyogames now), but for 3D.

Quaternion Project - This project so far contains a scene with AI vehicles that follow each other around. The main thing I was working on was how to get an object to turn left or right based on it's position and orientation or heading, and a target object. Unity3D has built in functions which will alow you to turn an object fo face another automatically, but I needed a simple left/right mechanism so I could send steering commands from the AI to the car. I got a lot of help from the Unity3D community forums, and many thanks to capnbishop, bunzaga, Frido, and runevision(and whomever else I missed) there.

The final bit of code is: whichWay=Vector3.Cross(transform.forward, myTarget.position-transform.position).y;. Basically turn right on a positive value and turn left on a negative value (or a zero to cover everything...because a zero could be behind you).
