Locking a rotation axis?

I searched on the forums, but it seemed like people were using raiseBodyFlags, or something like that to lock the rotation axes of a body. However, in visual studio, the OGRE3DBody class doesn't seem to have that function. How can I lock the axes of rotation of an object? Also, where is the correct documentation for NxOgre? I can't find any documentation for OGRE3DBody.

I'm pretty sure you're going to find no documentation anywhere.
If I were you I'd start going into the NxOgre code and modify as many things as you need for your project.

What do you mean by NxOgre code? Do you mean the tutorials on the OgreWiki? Because those are very basic and don't cover stuff like locking rotation axes, setting a maximum linear velocity, or using character controller.

Anyone know the answer to this (locking rotation axes)? It'd really help me out, since I can't for the life of me find it anywhere online.

It's the Enums::BodyFlags_???? you should be able set them via the RigidBodyDescription (description.mBodyFlags |= BodyFlags_FreezeRotationY).

Awesome, you're my hero! This is just what I needed.

One other thing that I'm having trouble finding: how do you delete an OGRE3DBody? The only code I could find called NxScene->destroyActor or NxScene->batchDestroyActor, but those don't seem to be in the API anymore. I only see destroySoftBody, destroyJoint, etc., but no destroyActor. Did the API change?

OGRE3DRenderSystem::destroyBody(OGRE3DBody*);
