Why Actor is not Moving with SceneNode

I enabled visualDebugger to see Physics Actor which describes rigidBody. In my case it is Box which I created that way:


[b]NxOgre::BoxDescription box;
box.mSize(60,100,60);[/b]
mBody = mRenderSystem->createBody(box_desc,NxOgre::Vec3(0.0f,1000.0f,0.0f),"boat.mesh",bodyDesc);
this->_hydroNode = mBody->getNode()->getSceneNode();


Now I can see bounding box around my model, but when I Moving SceneNode in frameStarted method that way:

this->_hydroNode->translate(move * evt.timeSinceLastFrame,Ogre::Node::TS_LOCAL);


my mesh is moving normally, but Actor(bounding box), is stand still. I thought that Actor and RigidBody connects to the same Node. What am I doing wrong???

Because Ogre does not know about PhysX or NxOgre, and therefore doesn't tell it that Actor has moved.

Translate your Actor, through the Body.

Ok thanx, but there is no such method in the Body class? How should I translate?

Adding a Force?

mmm, thanx, but is there any way to move the body without adding forces? For example: I pick up my object by mouse and drag it to another position without simulating physics, just change position.

There is no way to translate an Actor like you do in Ogre, other essentially your teleporting the Actor in small steps - this upsets the simulation, as it can't predict where the Actor will be.

There are two ways to do this;

- Forces
- Changing Linear Velocity.

You can also use a KinematicActor, which does support translation - but doesn't do forces, or responds to collisions, or gravity.
