Would you like to create a game in Blender, using a bit of artificial intelligence? Now you can! Two users from the Blenderartists forums, called p00f and Mmph!, published a series of eight tutorials on how to create a simple AI, using only logic bricks.
Here is a description about the AI by Mmph!:
This type of AI is not just useful for games, you can use them in Architectural visualization too... Just think about it, you get a job to make a scaled walk through of a strip mall.
Rather than just having the shops in the presentation, you can also have people walking around shopping! Or something even more simple, like a flock of birds, or a school of fish.
This method works in 2d games too, p00f did this method when we was making Zody the slug II, a 2d side scroller.
