Irrlicht Engine

yes, that solved the problem.

and, there is another one, it crashed when exiting the game, it seems to need to test if Game::get() has stopped before BroadcastClient::doAllWork(frametime) in GameEngine::run , as when Game::get()->shutdown() has been called if game stopped, all the resources are ...

brilliant!

the No.3 solves it!

but, then, it crashed in

Vector3D PointGroupObject::getRotation(int index)
{
return rotations[index];
}

that, rotations is 0 length, index = 0

it seems something is wrong in the lua script...

say, there are no obstacles between A and B, B and C, but, there is a building between A and C

A----------------*------B
|
something |
|
C

so, A and B are connected, B and C are connected, A and C are not through.

when NPC's desitination is C and the path is A, B, C, now it moves from A to B ...

waypoint culling is, say, it moves from A to B, then C.
and, when it is between A and B, and finds there is no obstacles to C, then, it can skip B, directly begin to move to C

have you ever thought of waypoint culling to smooth the path?

I tried it and I like the idea of binding components together with script and support multiplayer.

I downloaded the source from svn. the Head now is revision 165.
I use vs2005.

It seems not working even after many attempts.

the main change I made:
1. I rebuilt ode with 0.10.0, as ode-0.9 seems ...

finally, found out the reason:

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

sorry， it should be ESNRP_TRANSPARENT, though still not perfect

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();
}
