Getting an assetmanager without starting a SimpleApplication-instance

Troubleshooting gui
1

Hi,



I’m just trying to build a full initialized Geometry-instance cause i need to manipulate it.

BUT, I don’t need an instance of Simpleapplication, cause later the extended code has to run on a server and servers didn’t have Gui’s for their own(neither visible nor invisible).

My problem lies in getting a full initialized (Desktop-)Assetmanager.

Only after that I can give a material to the geometry.



Til now my testcode looks like this:

[java]

package own;



import java.net.MalformedURLException;

import java.net.URL;



import com.jme3.asset.AssetManager;

import com.jme3.material.Material;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.system.AppSettings;

import com.jme3.system.JmeSystem;



public class AssetmanagerTest {



/**

  • @param args

    */

    public static void main(String[] args) {

    Box box = new Box(1, 1, 1);

    Geometry geometry = new Geometry("boxGeo", box);

    AppSettings settings = new AppSettings(true);

    AssetManager assetManager = null;

    URL url = null;

    try {

    String string = settings.getString("AssetConfigURL");

    System.out.println(">>"+string+"<<");

    url = new URL(string);

    } catch (MalformedURLException e) {

    // TODO Auto-generated catch block

    e.printStackTrace();

    }

    assetManager = JmeSystem.newAssetManager(url);

    Material material = new Material(assetManager, "Common/MatDefs/Misc/SolidColor.j3md");

    geometry.setMaterial(material);



    System.out.println(geometry);

    }

    }

    [/java]



    and i get this:

null<<

Now I got want I want.

I thought that “AssetConfigURL” is anywhere set in jme3 but that didn’t happen so the right code is this:



[java]package own;



import com.jme3.asset.AssetManager;

import com.jme3.material.Material;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.system.JmeSystem;



public class AssetmanagerTest {



/**

  • @param args

    */

    public static void main(String[] args) {

    Box box = new Box(1, 1, 1);

    Geometry geometry = new Geometry(“boxGeo”, box);

    AssetManager assetManager = null;

    assetManager = JmeSystem.newAssetManager(Thread.currentThread().getContextClassLoader().getResource(“com/jme3/asset/Desktop.cfg”));

    Material material = new Material(assetManager, “Common/MatDefs/Misc/SolidColor.j3md”);

    geometry.setMaterial(material);



    System.out.println(geometry);

    }

    }

    [/java]
