IrrODE - an Irrlicht - ODE wrapper (now with SVN)

[Brainsaw]

You could try ISceneManager::addToDeletionQueue instead of removing the node directly. That way it will be removed once it's safe to do so.

[Lonesome Crow]

Ok! Let's be more specific...

After trying your tip, the same error remained. So, I decided to read and understand how "ISceneManager::addToDeletionQueue" works. And I found something strange...

What I want to do is simply to remove an object immediately after its creation, only to learn how could I create destructible physical objects on my simulation. Here is my code:

Code: Select all

        CIrrOdeSurfaceParameters g_pParams2;
	g_pParams2.setMode(dContactBounce | dContactSoftERP | dContactSoftCFM | dContactSlip1 | dContactSlip2);
	g_pParams2.setMu(dInfinity);
	g_pParams2.setMu2(0);
	g_pParams2.setBounce((dReal)0.6);
	g_pParams2.setBounceVel(1e-9f);
	g_pParams2.setSoftCfm(0.005f);
	g_pParams2.setSoftErp(0.00005f);
	g_pParams2.setSlip1(1.0f);
	g_pParams2.setSlip2(1.0f);

	ISceneNode* irrNode = smgr->addSceneNode(CIrrOdeSceneNode::nodeNameToC8(IRR_ODE_BODY_NAME), worldNode);

	CIrrOdeBody *pBody = reinterpret_cast<CIrrOdeBody *>(irrNode);

	pBody->setPosition(vector3df(5.0,15.0f,5.0f));

	IAnimatedMesh *Mesh;
	IAnimatedMeshSceneNode *Node;

	Mesh = smgr->getMesh("../../media/sphere.3ds");
	Node = smgr->addAnimatedMeshSceneNode(Mesh, pBody);
	Node->setMaterialTexture(0, driver->getTexture("../../media/arizona.png"));
	Node->setMaterialFlag(EMF_LIGHTING, false);
	Node->addShadowVolumeSceneNode();

	ISceneNode* irrSphere = smgr->addSceneNode(CIrrOdeSceneNode::nodeNameToC8(IRR_ODE_GEOM_SPHERE_NAME), Node);
	CIrrOdeGeomSphere *pSphere = reinterpret_cast<CIrrOdeGeomSphere *>(irrSphere);

	pSphere->setMassTotal(0.5f);
	pSphere->setSurfaceParameters(&g_pParams2, 0);
	pSphere->drop();

	pBody->initPhysics();
	pBody->drop();

	smgr->addToDeletionQueue(pBody);

The object is successfully created and the physics works well. I get problems only when I put the last line, trying to delete it.

As I could understand, "ISceneManager::addToDeletionQueue"puts the object on Deletion Queue and, when the deletion event is launched, doRemoveFromPhysics is called, safely removing all things in the right order and time.

If I understood right, the code I wrote should work. However, the code of "doRemoveFromPhysics" has something strange:

Code: Select all

void CIrrOdeBody::doRemoveFromPhysics() {
  CIrrOdeSceneNode::removeFromPhysics();
  if (m_iBodyId) {
    if (m_pWorld)
       m_pWorld->removeBody(this);
    m_pOdeManager->removeTreeFromPhysics(this);
    m_pOdeManager->removeOdeSceneNode(this);

    m_pOdeDevice->bodyDestroy(m_iBodyId);
    m_iBodyId=0;

  }
  else if (!m_bPhysicsInitialized && m_pWorld!=NULL) m_pWorld->removeBody(this);
}

"CIrrOdeSceneNode::removeFromPhysics()" removes the body from the "m_pSceneNodes" list but, five lines after, the same thing is made again on "m_pOdeManager->removeOdeSceneNode(this)"... This is redundant, but don't causes any error, it's only extra work.

Analysing each call on "doRemoveFromPhysics", all lists that would have removed objects, apparently have the right objects deleted. However, I'm still getting a "segmentation fault" or "ODE INTERNAL ERROR 2: Bad argument(s) in dGeomSetBody()" when "ISceneManager::drawAll" is called.

[Brainsaw]

Hmm ... I never tried to remove a node right after I added it ... I'll try that when I'm back from vacation next week. Maybe you could share your complete project with me, this would make it easier to reproduce the problem.

I'm actually not quite sure why the removal code is like this, haven't touched it for months

I solved the "no world!" problem. I found the way to recompile ode-0.11.1 to build ode_singled.lib instead of ode_doubled.lib. Now I can compile the helloOdeWorld but I have still problem with IrrOdeCar. There is following error:
fatal error C1083: Cannot open include file: 'CAdvancedParticleSystemNode.h': No such file or directory
I couldn't find it neither in "irrode" folder nor "ode-0.11.1" folder. Do you have any idea?

EDIT: This is how I solved the "no world!" problem. Actually it has nothing to do with the wrapper. I just changed the way I compiled the original ode-0.11.1 under VS2008 through Configuration Manager.

[Brainsaw]

Argh ... I think I should *really* include this code snippet into the download package. Before I can do so you should download the "AdvancedParticleSceneNode" from my homepage (http://bulletbyte.de/products.php?sub=irr&show=aps) and include it into your structure. Should work then.

[Lonesome Crow]

Ok! Hope we can get it to work!

You can download my project at: http://www.lia.ufc.br/~yuri/irrodetest.zip

It's very simple, only a test trying to put and than remove a sphere in a world with a terrain constructed from a heightmap.

By the way... I get the "no world!" message too, but to me this was not a problem until now. The physics apparently works fine.

It is obviously related to linked libraries. I think it means I need to add another .lib file. But which library I don't know. Currently I added "Irrlicht.lib ode_singled.lib libIrrOde.lib", I don't know what else is needed.

[Brainsaw]

Damnit ... can you check the VC projects for missing .h and .cpp files? Maybe I have forgotten to include some of those, as I hardly use VC apart from creating IrrEdit plugins.

[Brainsaw]

This is just a little update. I have added another force to the CIrrOdeAeroDrag motor used in planes. The new force uses a fraction of the uplift and sideward damp forces applied to the airplane to push it foreward. With this modification it is quite easy to fly a looping (this was almost impossible before).

Anyone Know what the problem might be?

[Brainsaw]

Are you sure you link agains the irrode lib? Seems that all IrrOde objects are undefined. I guess you'll have to adapt the Code::Blocks project file.

[Kordman916]

I have it linked.

Whats the proper way of building IrrOde in Linux?

[Brainsaw]

It should work the same way as under Windows. I think there's a Linux build target included, but it might not be up to date. As I don't have Linux there might be some headers or source files missing.

Btw: are you using the .a file that comes with the download package? That won't work, it's a Windows lib file created with MinGW.

[Brainsaw]

I have uploaded a new version of the IrrODE wrapper. This time I modified the IrrOdeCar demo (again), I added an autopilot feature to the airplanes. You need to start them, bring them to some altitude and activate the autopilot (Default key: "P"). The planes will then fly to some marks on the map (you can see some fire in the air (without smoke on the water though) at those points) by random. Yesterday I was just sitting in front of my computer watching the planes fly for about 20 minutes, then I took control over one of them and tried to hit the other two with the plane's gun.

Next planned steps: advance the autopilot so that the planes can also start on their own and modify the missiles to a heatseaking version. Just for the fun of it

[Brainsaw]

Just uploaded a new version with two enhancements:

added a free camera when no vehilce is selected. It can be controlled using the mouse buttons and moving the mouse

fixed a bug in the autopilot: sometimes invalid values were passed causing a crash in the ODE
