That sounds great, but could you give me an example of how to use the LivingUpdate event?

So I'm wanting to alter the ai of some of the mobs, more specifically the cow. I want to force it to eat grass. Now I've already been able to make it do that, but I've heard that altering the base classes of the game is not looked highly upon. How would I go about altering mob ai's without making changes to the base classes?
