Irrlicht Engine

Thanks! That was a great reply, very clearly explained.

I agree with you on your points about such assumptions, i mean before linking to the debug library there is no way to really figure out whats going on let alone find the root of the issue.

I'll fix this tonight when I'm home from work, but ...

Further information:

I've stepped into this and here is the code with added comment explaining:
//! Adss a scene node for rendering using a octtree. This a good method for rendering
//! scenes with lots of geometry. The Octree is built on the fly from the mesh, much
//! faster then a bsp tree ...

IAnimatedMesh* m_pWorldMesh;
ISceneNode* m_pWorldNode;

m_pWorldMesh = GetSceneManager()->getMesh("20kdm2.bsp");
m_pWorldNode = NULL;

if (m_pWorldMesh)
{
m_pWorldNode = GetSceneManager()->addOctTreeSceneNode(m_pWorldMesh->getMesh(0));
if( m_pWorldNode )
{
m_pWorldNode->setPosition ...

Sort of, you accomplish the change on the vector but the rotation needed to accomplish this is the important piece of information i need. Because i need to use it to rotate other dependencies.

InnerLib::vector3f vDirection1, vDirection2;
InnerLib::quaternion4f q;

q.rotationFromTo( vDirection2, vDirection1 );
q.makeInverse();

Rotate( q ); // Do the actual rotation

This is the basic code i'm using right now, assume the 2 vectors have good values.

So my goal here is to figure out the ...

If you make sure your tank treads are draw after your terrain, you could disable the z compare on the material. However this could easily cause issues with tank treads on the back of a hill side.

Your best bet is to likely add some epsilon to the positions of the geometry for the treads so that the ...

I'm attempting to maintain a quaternion rotation and use it to set the rotation on a scene node
Rotate( const quaternion4f& vRot )
{
vector3f v;
vRot .toEuler( v );
v *= RADTODEG;
pSceneNode->setRotation( v );
}

All seems fine right up until toEuler populates my vector with an undefined ...

Oh wow i feel pretty dumb not seeing the difference in the spelling.
Should have read the release notes.

Thanks for the help with that and all those warnings, all cleaned up now and ready to move forward.

Thanks again,
Chris

For some reason SViewFrustrum is not resolved, and i get a boat load of errors, it seems to be the only thing in Irrlitch that doesn't resolve correctly.

Has anything changed with SviewFrustrums, or the method in which you should utilize them? Has anyone run into this? or have any suggestions on ...

I'm simply looking for the position of the mouse around an origin of the center of the screen.

i've trouble shot this more and it seems like there is only an issue when i try to assign these values to members of a struct, defined in the class i'm working in...

Still confused but this seems to ...

vector2df vPos;
vPos.X = (f32)(event.MouseInput.X - 400);
vPos.Y = (f32)(event.MouseInput.Y - 300);


Is there any reason that this code would not work as expect, i get values in vector that make no sense. I've tried a bunch of permutations and different casts.

PS - the values in the event are ...

Alright, essentially i'm looking to figure out the best way to do things.

Say i have a main menu then a character menu then game, so whats the best way to switch between them?

Should i add all then remove all before i switch betwwen any of the differnt states... if so is there an easy way to do ...

Well i don't think you need to reply in that manor.

But i have tried
driver->setAmbientLight(video::SColorf(1.0f,1.0f,1.0f,0.01f));
and even with that it seems to be completely lit.
i can change it to say video::SColorf(1.0f,0.0f,0.0f,0.01f) and everything is red, so i'm a bit confused isn't the ...

So no one knows how to do this? Should i try creating a lightmap of some sort to do this? Seems like a waste to me...

Anyone have any comments on this?

First off as you'll read in the link 3d lines intersecting is extremely rare, and in some cases impossible because of floating point inaccuraccy.

Anyways you probably want to find the shortest distance between the two lines, check if thats within your colision threashold(is closer then 0.1 = an ...
