Im starting on AI now and found that the existing projects for AI linked to the wiki leave a lot to be desired. I was actually surprised to find that AI is not a core function of the engine since it is a core function of just about any game. I guess there's reasons for it. If there is such an animal, please feel free to enlighten me.
Anyhow, the wiki references Recast Navigation as a solution but the jNavigation port just seems to me to be to risky since its not active.
I found this java port, Recast4j that is an active port of Recast Navigation.
I thought it might be a good idea to ask those familar with jNavigation whether or not this looks like it would work with jmonkey and potentially be a replacement for jNavigation before I get stupid and spend a month on it.
Feel free to make other suggestions for jmonkey AI because the wiki needs some attention given to the subject.
