The mediafire link is working fine for me, and lots of other people have downloaded from it...

If you're sure it's not working then PM me an email address and i'll send it to you

the source is gonna change quite a lot for 0.4 (well most of it's the same but there's a lot of API breaking changes) but feel free to have a look!

im trying to get 0.4 ready asap but it's taking time unfortunately!

I downloaded source, and since I don't have Dev C++, I created Visual Studio projects, and built it against Irrlicht 1.4, I hade to make some modifications in order to build it, and I tried it on RPG example - it all works fine, except one thing I couldn't find whats the problem:
When Waypoints are visible (toggle with V key) other scene objects are messed up. It seems like floor is rendered over the sydney model, and boxes are duplicated, and waypoints are sometimes visible, sometimes not, when you move around, at some places everything looks fine, then when you move, it all messes up again...

when I turn off waypoint - everything looks fine.

any ides?

This is a problem with the change between 1.3.1 and 1.4... I tried upgrading to 1.4 a while back and this is the problem i saw (though didn't have waypoints turned off at any point so didn't realise it was fine without, so that could be a good clue as to what the problem is.... probably depth writing turned off on waypoints or something.. so thanks for pointing that out!). So when i saw these problems i just went straight back to 1.3.1 as i couldn't be bothered to sort out the graphics problems at that time

What you could try doing is editing CWaypointSceneNode (and CFOVSceneNode probably) and play around with some of the parameters in the material... such as ZWriteEnable... i'm just guessing that could be an issue, i believe its default value changed between 1.3.1 and 1.4...

I met the same problem. and you just need to register waypoint scene node as solid instead of automatic in the following function.

void CWaypointSceneNode::OnRegisterSceneNode()
{
if (IsVisible)
SceneManager->registerNodeForRendering(this, ESNRP_SOLID);

ISceneNode::OnRegisterSceneNode();
}

Score! I was going to make that change anyway as someone else said they got quite a good framerate improvement from doing that, i'll make sure the next version of IrrAI is 1.4 compatible then (well 1.4.1 probably!)

Lord knows when i'll get a chance to actually work on it though

sorry， it should be ESNRP_TRANSPARENT, though still not perfect

JP · Post by JP » Thu Jun 26, 2008 9:02 am

Surely shouldn't be transparent because there's no transparency used on it... I imagine there's more to the problem than meets the eye....

May you share your project?

Just tested out the demos... sweet, very sweet.

Halifax did a VS project for IrrAI 0.2 but it's been lost when the host decided to change name and start charging. If anyone can provide VS projects then that'd be great, i need to do that myself, will try to for 0.4. Hopefully i'll have a chance to do some work next week on it!

raptoravis · Post by **raptoravis** » Sat Jun 28, 2008 8:32 am

finally, found out the reason:

in CFOVSceneNode::CFOVSceneNode,
comment out the following line:
Material.MaterialType = video::EMT_TRANSPARENT_VERTEX_ALPHA

Oh I didn't know that happened.

I can always upload them to a more reliable server now that I have one. So I if you want, I could make a VS project for the newest version, 0.4.

Hi JP,
This projects is very interesting and I have question for it. Do You plan add NavMesh support for it? Or You planning show FPS example where bot can moves not only on Waypoints links, but on all map places. NavMesh is very easy idea to pathfinding in games, but maybe You have some idea to solved it only with waypoints system? For only traveling mode in game Waypoints are good solution, but in Fight mode I think than it isn't enought.
