Bleeding to BloodyMess problem (2 Parts)

Part I: (Solved)

Hi, I've recently moved from Bleeding (don't remember which version, I think T5 or something) to BloodyMess 1.5.5. I noticed that BloodyMess requires less code for creating an actor which of course is good but it created a problem for me.

On BloodyMess the code for creating an actor is for example:

void Ball::createEntity(float scale)
{
static const Ogre::Real mesh_scale = 0.02;
static const Ogre::Real physics_scale = 2.0;
// [OGRE] create player, set material and scale it
Ogre::SceneManager* sm= Ogre::Root::getSingleton().getSceneManager("Match SceneManager");
Ogre::Entity *E = sm->createEntity( name+"_entity", "sphere.mesh" );
E->setMaterialName("Soccer/Ball");
E->setQueryFlags(BALL);
mNode = sm->getRootSceneNode()->createChildSceneNode( name+"_node" );
mNode->attachObject( E );
mNode->scale( Vector3::UNIT_SCALE * mesh_scale * scale );
}

void Ball::createBody(Vector3 pos, float scale)
{
mBody= mNxRenderSystem->createBody(new NxOgre::Sphere(1), NxOgre::Vec3(pos), "sphere.mesh");
}

But I think this is wrong because there is no link between the OGRE3DBody (mBody) and the Ogre::entity (E) and Ogre::SceneNode (mNode) making imposible the visualization of the movement. In fact the ball appears and it doesn't move at all. I'll appreciate some help, thanks.

The Ogre3DBody already has an Ogre::Entity and an Ogre::SceneNode inside of it, so you don't need to create them manually. And by moving the Ogre3DBody, the SceneNode (and therefore its attached Entities or whatever ius attached to it), are moved accordingly.

Thanks, I updated the code and now it works.

Part II: Now I can't visualize the mesh, I can move the body but I can't see it. This is the code:

void Player::createBody(Vector3 pos)
{
mBody= mNxRenderSystem->createBody(new NxOgre::Box(1, 1, 1), NxOgre::Vec3(pos), "cube.mesh");
mBody->getEntity()->setMaterialName("Examples/10PointBlock");
mBody->getEntity()->setQueryFlags(PLAYER);
}

I see the floor and the camera moves when I move (this is how I now the body moves) but I can't see the mesh. Any Ideas?

Is your cube.mesh the right size? Your not using the Ogre cube mesh that is 100x100x100m in size, aren't you?

... I'm using cube.mesh from "...\Visual Studio 2008\Projects\Soccer\media\models\", the one that comes with Ogre. I was using that one also with Bleeding and I had no problem at all.

This is the code that works for Bleeding:

void Player::createEntity(float scale)
{
// this is a scale between Ogre and NxOgre
// for example if u set scale to 5 it will be 0.1 in Ogre and 10 in NxOgre
static const Ogre::Real mesh_scale = 0.02;
static const Ogre::Real physics_scale = 2.0;
// [OGRE] create player, set material and scale it
Ogre::SceneManager* sm= Ogre::Root::getSingleton().getSceneManager("Match SceneManager");
Ogre::Entity *E = sm->createEntity( name+"_entity", "cube.mesh" );
E->setMaterialName("Examples/10PointBlock");
E->setQueryFlags(PLAYER);
mNode = sm->getRootSceneNode()->createChildSceneNode( name+"_node" );
mNode->attachObject( E );
mNode->scale( Vector3::UNIT_SCALE * mesh_scale * scale );
}

//-------------------------------------------------------------------------------------
void Player::createBody(Vector3 pos, float scale)
{
// create node renderable parms for body
NodeRenderableParams nrp;
nrp.setToDefault();
nrp.mIdentifierUsage = NxOgre::NodeRenderableParams::IU_Use;
nrp.mIdentifier = mNode->getName();
// create body (name,shape,position,node renderable params,actor params)
// actor params is for example mass
mBody = static_cast<NxOgre::Body*>(mNxScene->createBody<NxOgre::Body>(name+"_body",new Cube(scale*2),pos,nrp,"mass:21"));

}

and this is the code for BloodyMess:

void Player::createBody(Vector3 pos)
{
mBody= mNxRenderSystem->createBody(new NxOgre::Box(1, 1, 1), NxOgre::Vec3(pos), "cube.mesh");
mBody->getEntity()->setMaterialName("Examples/10PointBlock");
mBody->getEntity()->setQueryFlags(PLAYER);
}

The only diferrence I see is the scale, on BloodyMess the Box is 1x1x1 and on Bleeding it was scale (1) by 2 = 2x2x2.

I found on Ogre.log that the material can't be assign but it is loaded correctly, here is part of the log:

Any help here? I'm totally lost.
