RAIN{indie} AI: Simple Waypoints Tutorial (1)

An article by mgear

Made a small tutorial pdf while testing RAIN{indie} AI system. (its free and works with unity indie!)
Going to try to implement it on the perlin dungeons later and have to try rest of the features too (like navmesh).

Goal of the tutorial was to get your monster to follow (go towards) given object, which is behind the wall.
And not a single line of code had to be written!

Download Tutorial (PDF):
RAIN AI – basic waypoints movement 1.pdf

Webplayer: (results of the tutorial)

Check this powerpoint file also (info about waypoints/AI)
Artificial Intelligence in Game Design (powerpoint)
http://www.csis.ysu.edu/~john/5895AI/podcasts/Maps.ppt

Feel free to send comments here, if you find some errors or a way of doing things easier etc.
Also there are many settings to adjust the AI movement, right now everything is at defaults..

Image#2: NavMesh created for dungeon
– That was easy, use Recast object to create navmesh
– Select either Recast option: Use Distance (remember to set it big enough so it scans your whole level)
– Or, Recast option: Use recast object, then assign your floor as recast object and navmesh is created from it

Hey, I’m looking forward to giving this a read when I get home.

How did you go with getting it to work in a perlin dungeon?

Cheers!

  NavMesh generation works fine (currently its created on the editor, see image#2),
  as the dungeon test is still in progress, current version webplayer (this one uses still angrybots mobs): http://unitycoder.com/upload/demos/PhotonPerlinDungeonsTest1/

I tried to go a bit beyond the tutorial and use the nav mesh but the “monster” is not moving eventhough i tried to recast the nav mesh with different settings. Does the RAIN need something different in order to operate with the nav mesh ?

thx good job

  One problem that I had, was that nav mesh came out too small at first (so the enemy wasnt on top of it..), enable [x] show span mesh (on recast object) to see it.
  
  other than that, could just try it on simple plane first,

  i think the plugin is already dead (and no longer updated) ? or where did you downloaded it?
  
  try using the new navmesh components,
