hi I use this sample code to make a cube:
myCube = mScene->createBody(
"myCube", "cube.1m.mesh",
new nxOgre::cubeShape(1), 1.0f,
nxOgre::pose( Vector3(-3,3.5,3),
Quaternion(Radian(Degree(45)),Vector3::UNIT_Y)
)
);
and works
but, if I need to apply a scale to this object, how can I do??
thanks
and last thing,
if my mesh is trimesh, what can I use instead of nxOgre::cubeShape(1)??
thanks

maybe something like this:
PhysicEngine::getSingleton()->getNxScene()->createBody("box.mesh", new NxOgre::CubeShape(5,5,5), Vector3(0,50,0), "Mass: 15, node-scale: 10 10 10");
I haven't tested yet, just looked at the sources so I'm not sure... I'm interested about the trimesh shape too

about trimesh i think that works this:
nxOgre::body *myHead = mScene->createBody(
"ogrehead",
"ogrehead.mesh",
new nxOgre::meshShape("ogrehead.mesh", mScene),
1.5f,
nxOgre::pose(
Vector3(-2.5,50.5,2.5), // Put it at -3, 0.5, 3
Quaternion(Radian(Degree(55)),Vector3::UNIT_Y) // Rotate it 45 degrees on the Y axis
)
);
about the scale seems that doesn't work!
bye

You can't use a meshShape with a dynamic body like that it has to be a static body.
For scaling the scenenode's entity you do; mBody->mNode->scale(w,h,d);

thanks, but how can I do this?
the sample above seems to work fine!
thanks!

With NxOgre 0.9:
mScene->createBody("cube.1m.mesh", new CubeShape(1,1,1), Vector3(0,3,5), "static: yes");
and with NxOgre 0.6 maybe something like:
mScene->createStaticBody(...);

thanks, but I wish a dynamic body with a trimesh mesh!
(I'm using the 0.4 RC 3)

You can't. It's a limitation of the PhysX physics engine.

argh!
also for phisx 7?
i'm trying to develop a car simulator, and I think that this stuff is very important, to check the colisions between the car and the objects
thanks!

This limitation is for ALL physics engines (Newton, ODE, PhysX). It would take tooo much time to compute I think...
But you can use more than one primitive shape for your car (maybe 4-5 CubeShape would do the trick).

Yep, usually most complicated objects are just a collection of shapes joined together as a compound body. I usually use convex shapes for each portion of the car.
