Debug mode

Hi, when I enable debug mode

mWorld->debug(true);

the application exit to desktop.

Is some other form to activate the debug mode?

Thx.

Yep, that's how you use the debug mode.

But are you using it after you create a scene or before? I fixed a bug a week or two ago if you launched the visual debugger before a scene was created it did not know what SceneManager to use hence calling random memory.

I expect the situation is the same with you, so just move mWorld->debug(true) after mScene = mWorld->createScene(...)

It crashes when I use it after create a scene. Indeed, I've tried to put it in tutorial101 and happens the same.

// 1. Start up NxOgre and pass on Ogre Root and the SceneManager as arguments.
mWorld = new world(mRoot,mSceneMgr);

// 2. Create our scene, this is where the physics is simulated into.
//We can have more than one scene, but physics objects of one scene
//cannot interact with another scene.
nxOgre::scene* mScene = mWorld->createScene("Main");
mWorld->debug(true);

// 3. Better add some gravity.
mScene->hasGravity();

// 4. Let's add a floor.
//Floors have an infinite size so we don't have to worry about anything
//falling off!
mScene->hasFloor();

// 5. Create a simple cube at X:0, Y:10m , Z:0 with a size of 1 metre.
//Due the gravity it'll fall then come to a rest.
myCube = mScene->createBody("myCube","cube.1m.mesh",new cubeShape(1.0f),10.0f,Vector3(0,3.5,0));

Hmm...It might be related to the debugging system itself perhaps with creating the mesh itself.

Are you using Dagon? Also are you using NxOgre Preview 3 or the CVS?

[Edit]

With any of the demos, when you press F2 to enable debugging does it crash then?

I'm using NxOgre Preview 3. In demo it happens something strange: when I press F2 doesn't happen anything. I have realized of which in the log file "Ogre.log" there are writings many errors, but do not seem to be related to the subject of debug.

The errors are:

PD: my mature language is not english, so...sorry if my english is too poor.

Hmm, what version of Ogre are you using?

As for that log there, completely unrelated and there not errors as such (It's for the sky in the vehicle demo).


And your English is better than mine!

I forgot it: I use OGRE 1.0.7 [Azathoth] version.

Any updates with this? I've got exactly the same problem running Dagon, Preview 3 (non CVS) and PhysX v2.3.3 - when I press F2 in any of the tutorials, or switch debug mode on manually I get a crash.

Ahh fixed it. What I did was change the material in nxOgre_debugNode.cpp to "Core/NodeMaterial".

Another person with a similar problem (although his didn't crash, just didn't show), simply changed the material file. Same thing I guess, although it didn't work for me (though I guess I might have made a mistake).

Hello,
I have same problem. How to fixed it?
I understand that you recompile your NxOgre but what change exactly?
Else how to do otherwise?

you can either make sure youre using the nxogre supplied materials, or edit one of the material files so that it's referencing a different image, or change it in the code(nxOgre_debugNode.cpp) and rebuild.

material NxOgre.debugNode
{
technique
{
pass
{
lighting off
scene_blend add
depth_check off
depth_write off
cull_hardware none

texture_unit
{
texture axes.png
}
}
}
}

in a material file

and in the debugnode.cpp

if(!Ogre::MaterialManager::getSingleton().resourceExists("NxOgre.debugNode")) {

Ogre::MaterialPtr debugMat = static_cast<Ogre::Material*>(Ogre::MaterialManager::getSingleton().getByName("BaseWhiteNoLighting").get())->clone("NxOgre.debugNode");
Ogre::Pass* pass = new Ogre::Pass( debugMat->getBestTechnique(), 0 );
pass->setVertexColourTracking(Ogre::TVC_AMBIENT|Ogre::TVC_DIFFUSE);
pass->setSceneBlending(Ogre::SBT_TRANSPARENT_ALPHA);
pass->setDepthWriteEnabled(true);

}

this->setMaterial("NxOgre.debugNode");

Just make sure that the code is referencing a material name that exists in a material definition...

EDIT: also make sure youve got axes.png there

Thanks for this info, works like a dream
