[SOLVED] Hit response / Falling down

If I let fall a sphere (or another object) down on a static body it isn't jumping back (or respoding in anyway). It is just lying there. What to do?

As I said I created this static object (a plane). The spheres I let falling down hit the plane (don't respond, except they don't fall deeper) and move on into the depth. Shouldn't they fall down after they left the plane?

It depends what you want it to do.

If you want the actor to really bounce. gives it shape a material, set that materials restitution to 1 and restitutionCombineMode to NX_CM_MAX

Could you give my a short code example, please? I'm not finding the needed functions

EDIT: Got it. Found this snippet here:

NxOgre::MaterialList* list = m_pNxScene->getMaterials();
NxOgre::Material* mat = list->begin();
while(!list->_atEnd())
{
mat = list->next();
mat->setDynamicFriction(50.f);
mat->setDynamicFrictionV(50.f);
mat->setStaticFriction(50.f);
mat->setStaticFrictionV(50.f);
mat->setRestitution(0.5f);
}

Create the material using mScene->createMaterial(...), then create the Actor/Body with this added to the shape params "material: materialname".

But this kind of material has nothing to do with the color and the others things specified by the Ogre::Material, right?

To change this I'll need a second material (one of Ogre)?

No, NxOgre deals only with the physics. Such things are left to Ogre as always.

But you shouldn't use that code snippet there. It's icky, and there are better ways to assign materials to Shapes.

Is this the right way?

static int i = 0;
Ogre::String name = "mat"+Ogre::StringConverter::toString(i);
NxOgre::Material* mat = m_pNxScene->createMaterial(name);
mat->setDynamicFriction(50.f);
mat->setDynamicFrictionV(50.f);
mat->setStaticFriction(50.f);
mat->setStaticFrictionV(50.f);
mat->setRestitution(0.5f);

NxOgre::Body * b;
NxOgre::SphereShape * s = new NxOgre::SphereShape(1);
b = m_pNxScene->createBody("sphere.2m.mesh", s, m_pCamera->getPosition(), "mass: 20, material: name");

Ogre::MaterialPtr mp = Ogre::MaterialManager::getSingleton().create(name,Ogre::ResourceGroupManager::DEFAULT_RESOURCE_GROUP_NAME);

Ogre::Pass *p = mp->getTechnique(0)->getPass(0);
p->setAmbient( ColourValue( sin( (double)m_pTimer->getMicrosecondsCPU() + 0.7 ), sin( (double)m_pTimer->getMicrosecondsCPU() + 0.5 ), sin( (double)m_pTimer->getMicrosecondsCPU() + 0.3 ) ) );
p->setDiffuse( ColourValue( sin( (double)m_pTimer->getMicrosecondsCPU() + 0.7 ), sin( (double)m_pTimer->getMicrosecondsCPU() + 0.5 ), sin( (double)m_pTimer->getMicrosecondsCPU() + 0.3 ) ) );
p->setLightingEnabled(true);
p->setCullingMode(Ogre::CULL_CLOCKWISE);
mp->load();

b->getEntity()->setMaterialName(name);

b->addForce(m_pCamera->getDirection()*550,NxForceMode::NX_IMPULSE);

i++;

Or you could do this:

mScene->createMaterial("Material1")->setAll(0.5f, 1.0f, 1.0f);
mScene->createBody("mySphere;sphere.2m.mesh", new SphereShape(1.0f, "material: Material1"), mCamera->getPosition(), "mass: 20");


Not everything has to be dragged out you know.


b = m_pNxScene->createBody("sphere.2m.mesh", s, m_pCamera->getPosition(), "mass: 20, material: name");



the material must be passed to the shape blueprint like shape param.
the code that betajaen wrote is the correct one.
