How to make brownian motion of a RigidBody animal AI?
I want to make a random ambling/ wandering script for a RigidBody which will be an animal. What's my first resource or step?
For random stuff this one: http://docs.unity3d.com/Documentation/ScriptReference/Random.html
You can try making it walk towards a position with random x and z values. When it reaches that point/ a certain time passes/ any other condition you want generate a new random target.
I've generated random paths in the past in two ways (not for ambling animals). The first was to generate a walk segment in a random direction. The object walked the segment and when reaching the end, a new segment of random length is generated. I like this method because it is easy to bias the walk so that it generally went in the same direction. That is, though the object walked randomly, I could bias it so that the chance the next segment walk would in a similar direction was high. This produced a tendency for gentle turns with occasional more abrupt ones.
For another project I generated a list of random points within a bounded area. Then I smoothed the line connecting them. I used iTween's path for the project. As another option for smoothing, I noticed this post has code by @Cody Schmidt for creating a smoothed path: How can I interpolate between points to create a smooth arc.
