Load saved j3o files

Troubleshooting import-assets
1

So I basically have a model(in j3o format), that I want to load into a game and then when the game is stopped, the model is saved and loaded again. So everytime I run the program there would be one more model in the game. My problem is, I want to have the saved j3o loaded in a folder called SavedGames. However, the code below works, because everytime the game runs i see the model loaded, but there is no folder called SavedGames generated in my assets folder.
[java]
package mygame;

import com.jme3.app.SimpleApplication;
import com.jme3.asset.plugins.FileLocator;
import com.jme3.export.binary.BinaryExporter;
import com.jme3.light.DirectionalLight;
import com.jme3.material.Material;
import com.jme3.math.ColorRGBA;
import com.jme3.math.FastMath;
import com.jme3.math.Vector3f;
import com.jme3.renderer.RenderManager;
import com.jme3.scene.Geometry;
import com.jme3.scene.Node;
import com.jme3.scene.Spatial;
import com.jme3.scene.shape.Box;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;

/**

    public class Main extends SimpleApplication {

    public static void main(String[] args) {
    //specify your settings here
    Main app = new Main();

     app.start();

    }

    @Override
    public void simpleInitApp() {
    //load model from save
    String userHome = System.getProperty(“user.home”);
    assetManager.registerLocator(userHome, FileLocator.class);
    try{
    Node loadedNode = (Node) assetManager.loadModel("/SavedGames/savedgame.j3o");
    rootNode.attachChild(loadedNode);
    }catch (com.jme3.asset.AssetNotFoundException e){}

     //display model
 Spatial mymodel = assetManager.loadModel("Models/MyModels/mymodel.j3o");
 mymodel.move(FastMath.nextRandomFloat()*2-5, FastMath.nextRandomFloat()*2-5,FastMath.nextRandomFloat()*2-5);
 rootNode.attachChild(mymodel);
 DirectionalLight sun = new DirectionalLight();
 sun.setDirection((new Vector3f(-0.5f,-0.5f,-0.5f)));
 sun.setColor(ColorRGBA.White);
 rootNode.addLight(sun);

    }
    @Override
    public void stop(){
    //save model
    String userHome = System.getProperty(“user.home”);
    File file = new File(userHome + “/SavedGames/” + “savedgame.j3o”);
    BinaryExporter exporter = BinaryExporter.getInstance();
    try{
    exporter.save(rootNode, file);
    }catch(IOException ex){
    Logger.getLogger(Main.class.getName()).log(Level.SEVERE, “Error: Failed to save game!”, ex);
    }
    super.stop();
    }

    @Override
    public void simpleUpdate(float tpf) {
    //TODO: add update code
    }

    @Override
    public void simpleRender(RenderManager rm) {
    //TODO: add render code
    }
    }
    [/java]

Well if you create the SavedGames folder in your user.home directory, why do you expect it to suddenly appear in the assets folder anyway?

To make it appear in the Asset folder (if not moved anywhere)
[java] String assetFolder = System.getProperty(“user.dir”) + “/assets”; [/java]

Where exactly is the user.home directory? I’m doing this off a tutorial so I still need to orientate myself. I checked the game project folder and there isn’t a SavedGames folder.

Thank you! I’ve found it and there indeed is a savedgames.j3o file.
