I'm building an American football simulation(think football manager), and am wondering about the best way of implementing AI based on various inputs which are weighted based on the personality of the NPC...I have a version of Raymond Cattell's16PF model built into the game to be able to use their various personality traits to help guide decisions.
I am going to use this extensively so I need this to be both flexible and able to handle many different scenarios.
For instance, a GM has to be able to decide whether he wants to resign a veteran player for big dollars or try and replace them through the draft. They need to be able to have a coherent system for not only making a decision in a vacuum as a single decision but also making a decision as part of a "plan" as to how to build the team...For instance it makes no sense for a GM to make decisions that don't align with each other in terms of the big picture. I want to be able to have the decisions take in a wide range of variables/personality traits to come up with a decision.
There is no NPC per se...There isn't going to be any animations connected to this, no shooting, following, etc...just decisions which trigger actions. In a situation like a draft, there is one team "on the clock" and 31 other teams behind the scenes working on trying to decide if they want to try and trade up, trade down, etc which can change based on things like who just got picked, the drop off between the highest graded player at their position/group and the next highest graded player in that position/next group, if a player lasts past a certain point, etc...
There needs to be all of these things going on simultaneous for all the teams, obviously the team on the clock is goifn to have to decide whether it wants to make a pick or take any of the offers to move down in the draft from other teams that might want to move up, etc..
So I am planning on making use of something called Behavior Bricks by Padaone Games( bb.padaonegames.com )which is a Behavior Tree but in conversations with others who have worked on AI in major projects like this(EA sports) they said to combine this with a State Machine.
My question is would I be able to do this using just Behavior Bricks or would I need to build the state machine separately? Is there something else already created for this type of purpose that I could take advantage of?
