Hi friends,

I don't know if any of you have ever play "Clive Barker's Jericho":


If you haven't you should, but any ways I'm sure that you have play other games were you have team that react by itself without the direct interaction of commands given by the player. I mean: shot to the enemies even if you are not shooting, smart enough to protect them self from been shoot and interact with the player if needed.

Well, the thing is I'm trying to develop an script to do that but I have no clue were to start. After several intents the team players still acting like robots and they get stock in the wall and stuff like that.
Please I need your help. If you know were I can find any script that gets close to what I want or if someone has some pre-made script to share.

Thanks in advance.

basically you can use search algorithms for that (I'd recommned the a*).
You have a basic set of decisions
for example:
- heal teammate
- attack enemy
- use skills
- move to cover
- whatever

and the you use the a* to decide what to do. a simpler method would be a finite state machine (but you'll still have to use an a* for pathfinding though. )

If you know how to script good a* or state machines it is no problem at all.
You may look into the A* tutorial at the AU-resources.
You may also look into behavior trees
and here is something about navigation meshes (might also be interesting for you)

At first i would recommend to get a working pathfinding code.
You might use intense pf 3.
And then you start building your behavior.
Draw a state graph containing all the actions of you npc with description.
like this:


Then start slowly scripting the actions themselfes.
When you have all this ready 2 go you start with the behavior tree/state machine that decides what the bot is going to do.

Great!. That sounds good. I'll going to try that. By the way ... I can use that same solution for enemies also, correct?

Of course.

Search forum for something like, companion_ai... I use to use it for creating my hostage ai with simple state machine... You will find very good example of creating simple ai that do not stuck in obstacles... And uses simple pathfinding to follow player... All you will need, is to understand the code, and add just some state machines, as you wish... Good luck, I hope you contribute it...

Yea!! so soon as I have something to show I'll post it. Thank you guys.

You are welcome bro.
