Hi Brucey, if you are getting bored over your current project (whatever that is): http://opensteer.sourceforge.net/ "OpenSteer is a C++ library to help construct steering behaviors for autonomous characters in games and animation. " MIT license.

I wonder how it would be possible to integrate this in a physical simulation like Box2D... I suppose it's probably hard but interesting library Volker.

Running over the documentation there are always steering forces returned by the functions. I dont know box2d, but for Newton this should be useable.

I'd like this one too :) Cheers Charlie

Ditto...

I actually once got half-way through a full port of opensteer to BlitzMax, but tossed it, since that was obviously a rather foolish venture :-p But yeah... it's been on my todo list for a while.

Is this actually something easy to use ? I'm pretty bad at AI behaviour and FSM. I currently have some fish and birds that could benefit from such a library. Would be awesome to have something smooth and natural for them. But since my game is physic based, all I have at my disposal is ray-casting, sensor and collision detection. I wonder if Opensteer is conceivable without any way-points or map drive assistant. Is this still applicable with 2D platform game ? If someone has clues on this, it's welcome :) EDIT The driving example is maybe what I'm searching for but hard to imagine the constraint in a 2D platform world !

Have a look at this...http://www.red3d.com/cwr/steer/ Its been posted before but is really interesting

I ask this question on the official forum : https://sourceforge.net/projects/opensteer/forums/forum/264792/topic/3431491/index/page/1 Some say it would be feasible to do so. I should have a look at the API to get an idea. Brucey, is this portage more complicated than others ?

Brucey (Posted 2009) [#10]

It's only complicated because of all the abstract classes being used, which require Max implementations calling into BlitzMax wrappings. Just messy backend stuff really.

Armitage 1982 (Posted 2009) [#11]

Probably it's because OpenSteer is still under heavy developpement as I read somewhere. Maybe it's not the answer to my problem then :)

Is anyone know something similar? I'm having hard time with FSM enemy players. Finite state machine is not really easy to use with Box2d.
