Update #7

Update #7: AI Video

Hey guys! Antharion is all about immersion and creating a beautifully unique and alive fantasy world for you to explore. In order to make this world feel more convincing, we've spent countless hours trying to make its inhabitants feel more intelligent. In Antharion each NPC will have its own unique temperament, personality and combat strategy. We want the creatures of Anthartion to react to your actions in tangible ways so as to make everything you do feel more meaningful and important. In this video we demonstrate just a few of Antharion's working AI features...

[Note: In the video you'll notice NPCs moving sometimes quickly without the player having moved. This is merely for the sake of demonstration and is achieved by holding down space bar which has the effect of passing on the player's turn]

      @Solar, we're planning (and working on) video updates showing off all of what you mentioned :)

      @Orphic Thats what i wanted to hear, thanks! Any chance we got to see a typical town scene which shows some of those npc daily routines + some cool music in a coming update maybe? Together with a full day timelapse to see the different light situations, please. :)

      Looks very promising and seeing the Guard follow the NPC and arrest the player reminds me of Ultima 5 hehe. Will NPCs have Work/Sleep/Eat/Relax routines as well? (I assume so since you want to go for a world like found in Ultima...)

      @solar, the rat in the maze was merely for the sake of demonstrating Antharion's pathfinding capabilities. In an actual game, the way a monster approaches your party depends on a combination of factors including: your party's overall power, the monster's power relative to your party, the monster's temperament, the monster's ai type (conjurer, healer, ranged attack, melee, or some hybrid), monster's hp, your hp, monster's sp, etc. Monsters in the actual game have a certain awareness of the player which diminished over time and through space, the monster must keep his sights on your party and continually update his awareness of your party in order to pathfind his way to you so line of site is inextricably linked with the monster's ability to pathfind, cast spells, or do whatever else.

      Antharion's engine generates waypoints depending on the map's layout, then it calculates the paths between everyone one of the waypoints so it always knows the shortest path between any two that are connected - otherwise known as an all-pairs shortest path approach.

      Regarding that rat in the maze: I wonder if that would be the right kind of pathfinding a rat would possess in a realistic setting? How does it know what the correct path is? A realistic AI should simulate errors too?
      I just hope that not every enemy we see in the game rushes wildly towards the our party. I hope there are restriction for line of sight (so we could sneak past an enemy) or even "area of hearing". A different thing could be interest in the party, with high interest an enemy would attack our party because he hopes for treasure or because he feels intimidated, otherwise a poor rat or minor enemy would probably just flee from us, at least when we got stronger and wear big armors and weapons.

      @Christoph, we originally used an A* but later switched to a highly-optimized preprocessed waypoint system that ended up being much faster and just as good.

      @Ghun, There's no scripting going on, aside from the guards' dialog when he catches up to you. The behavior is generic, though it depends on the individual NPC's temperament. For example: an aggressive NPC who loves fighting won't even bother going for the guard, he'll just attack, a timid NPC may just run away, etc. Sometimes the NPC may yell and alert other NPCs who themselves will run in search of a guard. And once a guard is alerted he'll call out to other guards in the vicinity. We find this system works quite well in terms of producing interesting and emergent behavior.

      Nice work on the NPC behavior. I always hate it when NPC are oblivious to stealing, and I wouldn't have expected it to be handled so well in this game.
      A question though: Is this behavior generic (e.g. the NPC will try to find any guard in the vicinity) or scripted for each specific situation?

      Nice update. I love the use of white walls and floor tile in the video!

      Heh, that pathfinding reminds me of the robocode assignment for A* we had in one of my university classes ;)
