Custom AI coding?

[spamdog]

Hi everyone,
I was wondering if it is going to be possible in HL2 to write your own custom AI?
If not, would it possible to modify the existing AI of certain enemies?
Were either of these possible in the original HL?
Hope someone knows the answer to these questions.

It will be possible.

You could write a completely new AI and insert it in to the Source engine but that wouldn't be very practicle.

I think creating an AI with new behaviour based on the Source's AI frame work shouldn't be too hard. I take it thats what you want and not the first thing I said?
