+ // REMAINING ATTACHMENT ISSUES:
+ // We get to this function when the object is an attachment that needs to
+ // be attached to its parent. If a bone is set we attach it to that skeletal
+ // bone, otherwise just to the object's origin. Attachments should not copy parent
+ // position as that's laggy... instead the Irrlicht function(s) to attach should
+ // be used. If the parent object is NULL that means this object should be detached.
+ // This function is only called whenever a GENERIC_CMD_SET_ATTACHMENT message is received.
+
+ // We already attach our entity on the server too (copy position). Reason we attach
+ // to the client as well is first of all lag. The server sends the position
+ // of the child separately than that of the parent, so even on localhost
+ // you'd see the child lagging behind. Models are also client-side, so this is
+ // needed to read bone data and attach to joints.
+
+ // Functions:
+ // - m_attachment_parent is ClientActiveObject* for the parent entity.
+ // - m_attachment_bone is std::string of the bone, "" means none.
+ // - m_attachment_position is v3f and represents the position offset of the attachment.
+ // - m_attachment_rotation is v3f and represents the rotation offset of the attachment.
+
+ // Implementation information:
+ // From what I know, we need to get the AnimatedMeshSceneNode of m_attachment_parent then
+ // use parent_node->addChild(m_animated_meshnode) for position attachment. For skeletal
+ // attachment I don't know yet. Same must be used to detach when a NULL parent is received.
