TreeCollision Problem

Hello!
my Programm crashs when i use TreeCollison from my Terrain SceneManager


SceneNode *ter;
ter=mterrain->getTerrainRootNode();
OgreNewt::Collision *terraincoll=new OgreNewt::CollisionPrimitives::TreeCollision(mWorld,ter,true);
OgreNewt::Body *terrain=new OgreNewt::Body(mWorld,terraincoll);
delete terraincoll;
terrain->attachToNode(mterrain->getTerrainRootNode());


and i get this Error
"10:12:43: OGRE EXCEPTION(2:InvalidParametersException): Object index out of bounds. in SceneNode::getAttachedObject at C:\SoftwareDevelopment\C++\MinGW\ogrenew_HEAD_clean\OgreMain\src\OgreSceneNode.cpp (line 159)"

Have you created child scene nodes into terrainRootNode? If so, that´s the problem. You have to mod the treecollision code if you want to pass a node with child nodes. I have done it and it works well.

isn't
CollisionPrimitives::TreeCollisionSceneParser
supposed to do that for you?

thanks for the answer i get no error if the scenenode has no child.
but if i use treecollisionssceneparser my entities fall through the terrain

Can you see the collision lines for your objects and check is it even making the collision shapes for your meshes or not??

no i can't see the lines

hmm.. i'll have to check it out.. i've tried the sceneparser once, but don't remember if I did've a child node. I remember having two entities, don't remember if they were attached to same node or in a parent-child fashion..
