How to get mesh from a .irr scene?

That's a problem when I want to get a mesh from .irr scene.Here is the codes.

smgr->loadScene("anting.irr");
//=============================================
ISceneNode *scene_node=smgr->getSceneNodeFromName("rooms");
IAnimatedMesh *levelMesh=0;
if(scene_node && (scene_node->getType()==ESNT_MESH))
{
levelMesh=(IAnimatedMesh*)scene_node;
}
ISceneNode *levelNode=0;
if(levelMesh)
{
//The problem is here...
levelNode=smgr->addOctTreeSceneNode(levelMesh->getMesh(0));
}
//=============================================

Why can't I use "levelmesh->getMesh(0)" to get a mesh?Every time I execute this,the compiler occur an error.I have no idea,can someone give me a hand?

you cant typecast a ISceneNode into an IAnimatedMesh.
youd have to typecast the scene_node to IAnimatedMeshSceneNode.
then you can use the getMesh() method.

also this might help :

although it goes through adding colission to the mesh, it also shows how to get the mesh in order to set the collision to it
