Hi
Is this valid ? In the Manager class headerI created a SharedPtr <Scene). I attempted clearing it then directly pointing the pointer to the pass pointer but I don’t think that is working.
Viv
[code]/// Set Scene
int Manager::SetScene(SharedPtr scene)
{
/// point
scene_ = new Scene(context_);
scene_ = scene;
/// Node
Node * parentnode = scene_ -> GetParent();
String nodename = parentnode ->GetName();
cout << nodename.CString() <<endl;
}
[/code]
The above creates a new scene and stores it in the pointer scene_
The above overwrites the newly created pointer above with the value of whatever is in scene, passed to the method. If scene is an empty pointer, scene_ is now empty. If scene is an existing Scene, then scene_ is now pointing to that existing scene. The newly created scene_ allocated above is gone.
The above tries to get the parent of scene_, but a Scene is a root-level Node be default. A newly constructed scene is going to have a null parent.
The above tries to dereference the null parent of the scene to obtain its name. Dereferencing a null pointer is, of course, an error.
I honestly can’t even begin to imagine what it is you are trying to accomplish here, but I suspect that 24+ hours without sleep might be a part of the reason for that.
Lol. yea. It’s late and I’m tired.
After making that note. It works. I think it’s bed time for me.
Ultimately. I want to recursively look through the Scene and save all nodes not generated including the components(Manual(Editor or in-client addition) or Automatic (NPC’S, spawn points, etc)). Then also be able to do the opposite like load.
I would add that in normal use a scene is always going to have a null parent. Or, Urho will not specifically stop you from adding a scene as a child to another scene or another node, but it does not make sense and you can expect errors (eg. node/component ID allocation clashes) or even outright crashes to result from that.
The new code is this. Any recommendations??
[code]
/// Main Save scene
int Manager::SaveScene(int mode)
{
/// Check if scene exist
if(scene_==NULL)
{
return 1;
}

unsigned int childrencount=scene_->GetNumChildren();
cout << childrencount << endl;
children_ = scene_->GetChildren();

}
if(childnode->GetNumChildren())
{

}
else
{

}
}
}
int Manager::SaveSceneNodeComponents(Node *node)
{
/// Define temporary pointer for components
Vector< SharedPtr< Component > > subcomponents_;
/// If node has no components
if(node-> GetNumComponents ()==0)
{
cout << " Node has no components" << endl;
return 1;
}
/// Get children node
subcomponents_ = node->GetComponents();
/// Loop through components
for (Vector<SharedPtr<Component> >::Iterator i = subcomponents_.Begin(); i != subcomponents_.End(); ++i)
{
Component * subcomponent = *i;
cout << subcomponent->GetTypeName().CString() <<endl;
/// READ EACH COMPONENT AND GET ATTRIBUTES
if(subcomponent->GetNumAttributes ())
{
/// set virtual const
const Vector<AttributeInfo>* attributes = subcomponent->GetAttributes();
/// loop through attributes
for (Vector<AttributeInfo>::ConstIterator i = attributes->Begin(); i != attributes->End(); ++i)
{
/// output info
cout << i -> name_.CString() << " type " << i -> defaultValue_. GetTypeName ().CString() <<" value" << i -> defaultValue_.ToString().CString()<< endl;
}
}
}
return 1;
}[/code]
The result is okay but I think I have to differentiate a subchild because the output looks like one long list

Game Lifetime type Float value-1What is wring with using Scene::SaveXML()?
I have to manually go through the node structure and not save Generated and a few other types of components(like camera and others that will throw off everything). I really don’t want to modify the base Scene.cpp code to do so.
I want output that can be imported into the Editor.as or another Editor. I put the latest semi-close code on github.
I made some code to try to replace the Export Node or SaveXML parsing through a scene. So far the output is as follows.
Any help is appreciated? I should be able to loadXML with the output since Editor.as is written in Angelscript directly linking the Save XML(Differiental) will not happen soon unless a c/c++ editor becomes available.

The new code produces results about 50% there. I have not figure out why the first node don’t get the right attributes. I also not sure how to get the texture information and id’s so it’s clearer.
