Problems with getSceneNodeFromScreenCoordinatesBB

[Guest]

The Function getSceneNodeFromScreenCoordinatesBB() returns the SceneNode which is under the cursor, for example, and which id is 9.

Code: Select all

// The Mesh
room = smgr->addMeshSceneNode(tangentMesh,NULL,10);

core::vector3df cursor = device->getCursorControl()->getPosition();
scene::ISceneNode* selectedMesh;
selectedMesh = smgr->getSceneCollisionManager()->getSceneNodeFromScreenCoordinatesBB(coursor,10);

With this code the getSceneNodeFromScreenCoordinatesBB() returns the room for example.
But there are also other Nodes in the scene, too.
And the getSceneNodeFromScreenCoordinatesBB() returns also the other Nodes,too, although these other Nodes have different ID's.
Why is the function returning these, too?

You need to understand what mean idBitMask first.

Oh ok thanks

The above link clears up the confusion about how the bitMask works, but I found that I also have to set the ID of the baseLevel node to 0 so that it still doesn't get returned. I'm sure there are better ways to do this, but this worked for me.
