Using OpenSteer with Irrlicht

Hello again. I was asking about navmeshes a little while ago, but I'm still looking at other options for how to handle my AI. Just for info, as far as my navmesh goes, I can generate an array of data from the mesh itself but I'm stuck on getting the program to work out which ones are connected, but I've got a solution in mind for that.

Anyways, I was pointed in the direction of OpenSteer as an option for my AI navigation. I've downloaded the demo and the source code and combined with a little bit of A* to work out a simple path, it looks like it will suit my needs fairly well. The problem I'm having, is that I haven't got the slighest idea on how to integrate it with Irrlicht.

What I really need is to look at a few examples. I've seen a few on the forums, but all the links go nowhere (http://irrlicht.sourceforge.net/phpBB2/ ... =opensteer, http://irrlicht.sourceforge.net/phpBB2/ ... =opensteer). Does anyone has either (or both) of these projects that I would be able to poke around for ideas? Thanks in advance.

hehehe, the boids example I hosted here
but remember this is about 3 years old and uses the Irrlicht version from that time, so you'll have to adapt it to newer versions...

You see, that's exactly what I needed. Had a look through that and it looks alot simpler to implement than I thought. Seems like all I need to do is inherit from the SteerLibraryMixin, call the steerFor/steerTo functions that I need, convert the STL vector to an Irrlicht one, then feed that vector to my physics to apply the right force to the entity. I'm hoping that I got that right <>

I'll probably set up a demo program just to see if I can get it all to work with Irrlicht before I let any of it into my full project (even if there's not much there at the moment). Thanks for that example.
