[Solved] Passing Scene_ and custom SaveXML(parsed nodes)

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;
}

/// point
unsigned int childrencount=scene_->GetNumChildren();
cout <<  childrencount << endl;

children_ = scene_->GetChildren();

/// loop each child
for (Vector<SharedPtr<Node> >::Iterator i = children_.Begin(); i != children_.End(); ++i)
{
    /// Create a new child instance
    Node* childnode = *i;

    /// Get node infomration, check for children, and check components
    if(childnode->GetName().Find("Generated",0,false)==String::NPOS)
    {
        cout << "Node :" << childnode->GetName().CString() <<endl;

        /// GET ALL NODE INFORMATION

        if(childnode->GetNumChildren())
        {
            SaveSceneNode(childnode);
        }
        else
        {
            SaveSceneNodeComponents(childnode);
        }

    }

}

}

/// Recursive

{
/// Define a temporary pointer

    /// Get node infomration, check for children, and check components

        // set virtual const
        const Vector<AttributeInfo>* attributes = childnode->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;
        }


        if(childnode->GetNumChildren())
        {
            SaveSceneNode(childnode);
        }
        else
        {
            SaveSceneNodeComponents(childnode);
        }
    }
}

}
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

What 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.

I’m trying to get output similiar to

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.
