Three Simple AI Behaviors v0.2

Almost a year and a half ago, I wrote up a small Unity3D project that demonstrated a few basic AI behaviors (patrolling, wandering, following). You can check it out here. I get more emails and questions about that simple project than anything else on this website – I guess simple projects that demonstrate the basics of game AI are something people are interested in!

Anyway, this project had a major problem – the sample NPCs didn’t deal with changes in terrain height well (or at all). This has been bugging me for a while, but I haven’t had a chance to fix it until tonight. Check out the project page for a new version, complete with NPCs that don’t burrow into the ground at the first sign of a change in the y-value of the terrain underneath their feet.

    I cannot get it to work atall. When i import this project into Unity nothing shows up.

    I have tried to just take out the AI scripts and use them in a different project but i still get the zombie flying up into the sky and ignoring the hills.

    I know you have already done alot but just extracting the AI from the project and saying how to add it to another project would be great.
    I get errors about missing behaviours.
    Also maybe it is because i am using a mac and i see an exe in the project which is not going to work.

    Thanks,

    Jez
