ai graphs - part 2 from davros on Vimeo.
The AI graph is your guideing lines for the actors to move along. Without an AI graph, they will not move as they do not know where they can go.
The will wander off the AI paths and into areas that do not have a line, so it's not like you need to paint the whole map surface, but they will mostly follow along the lines.
Giving them a patrol path in the editor is like giving them ares/lines along which they can move. They will try to follow your directions, if the AI graph will allow them to.
Green lines = AI graphnodes and connecting lines.
Red lines = the humans/mexicans patrol path
dotted red lines = routes the AI may take...after all they do have their own minds!
AI get to point A, become lost in which way to go, usually start to see them taking completely different routes all together while trying to find point B.
AI get to point B and usually do 1 of 2 things:
AI have no clear way to get to point B. This may lead to non responsive behaviour and/or the AI wandering about - but they will likely get there eventually.
AI should move along with no issues.
