While developing a game, I wanted to enable the autonomous characters to see where they’re going – that is, to tell them what they’re about to stumble into, without using colliders. The answer was to cast a Ray, angled slightly downward, in front of the character, so it can see if it’s about to walk into a tree, or off a cliff, before it happens.

How to create infinitely varied animation with your Unity characters.
A very powerful feature in the Unity Editor is the Blend Tree. This is an extension to an Animation Controller, which allows you to ‘blend’ the joint movements of multiple animations and control the ratio of blending with one or more parameters.
UPDATE: The last 2 major releases of Unity adversely affected how UnitySteer steering behaviours play with non-kinematic RigidBody components. If you’re having trouble combining your physics with steering forces, see this enhancement I added, which may or may not become a pull request at some point (although I think the UnitySteer project is not actively maintained any more).
I knocked up a quick demo to show how you might create a Unity game, which uses either keyboard input, or the accelerometer of a mobile device, without having to change any code, include any third party libraries, or use conditional compilation.
