Hey!

This was a fun one to make - I did loads of research, and ended up with more info than I could fit in one episode. I plan to do a follow-up bonus video with more on how AI actually works. And I'll give you guys and gals the rest of the research, too. So, more to come on this topic.

Cheers!

What Makes Good AI? | Game Maker's Toolkit

When we talk about good AI, we often think about highly efficient and aggressive enemies in shooters like FEAR and Halo. But surely there's more to good artificial intelligence than this?

Fantastic video Mark. I thought this was one of your best. Another example I saw in BoTW recently (I'm lttp) was that when you pull out a bow or prepare to throw something, the enemies begin strafing around you and zig-zagging. This may be smart AI, but more importantly it makes the ranged combat just as interesting as the melee combat because there are still atomic decisions to be made (cribbed that term from this video <a href="https://www.youtube.com/watch?v=5kFqrI11xTc&amp;t=2s" rel="nofollow noopener" target="_blank">https://www.youtube.com/watch?v=5kFqrI11xTc&amp;t=2s</a> ). Also, was that an homage to Every Frame A Painting at 7 mins in?

Great video! I'm a narrative designer who writes barks for a living, and I also happen to be working with the designer who wrote the specific barks you highlighted from Splinter Cell: Blacklist. (He was thrilled when I showed him the video!) Using voiceover to communicate AI capability is very challenging work, especially because it's so hard to make those barks sound natural and in-character, but when nobody notices, it means we've done our jobs well. I really appreciate the way you emphasize that "good AI" combines the efforts of many different people, some of whom couldn't program their way out of a paper bag. ;)

The AI for Mr. Freeze in Arkham City was a particular favorite of mine for doing what you call out in MGS5 and Alien Isolation as tricks to give the appearance of learning. Made for a very memorable boss fight.

Probably my most favourite video thus far. I love the topic and how much research you have dedicated to really exploring it - just looking through these 2002 (!) GDC slides was really interesting! Also: great writing! It's really informative but at the same time funny what makes for a really entertaining mixture (that Instant Replay though :D) . And I couldn't help but enjoy the jab against the inherent sexism of most of the "damsel in distress"-escort missions ;) You are doing great work - I am happy to somehow be part of that :)

Great video again. A bit offtopic question: have you considered sorting the patreons list before adding it to the video? ^^. Excel can do it for you in a sec :P

2017-06-01 05:12:03 How should I sort it? Should I jumble it up randomly each episode, do you think?

Simply a great video. I've been watching GMT for a while now, but i NEED to be a patreon after this one. haha. Keep up the awesome work, Mark

Really awesome work Mark, I was curios I didn't see you mention anything about the A.I. in the dark souls game. Are those just enemies with simple behavior and lots of aggression? Would love to hear your thoughts. Also I was wondering if you would consider doing a comment response video for your patrons with each of your GMTK videos.

On DS - I mean, they have some clever tendencies but the fact you can cheese them and circle strafe around for the backstab makes them a bit dumb at times. There's a rumour that From uses a similar type of AI architecture to FEAR, which is weird. As for comment response videos - not something I had ever considered but I'll give it some thought.

I think this is your best video.
