My first try to get jmonkeyengine running with scala

Application.scala

package coz

import com.jme3.app.SimpleApplication;
import com.jme3.material.Material;
import com.jme3.math.Vector3f;
import com.jme3.scene.Geometry;
import com.jme3.scene.shape.Box;
import com.jme3.math.ColorRGBA;
 
/** Sample 1 - how to get started with the most simple JME 3 application.
 * Display a blue 3D cube and view from all sides by
 * moving the mouse and pressing the WASD keys. */
class Application extends SimpleApplication
{
    override def simpleInitApp()
    {
        var b = new Box(1, 1, 1); // create cube shape
        var geom = new Geometry("Box", b);  // create cube geometry from the shape
        var mat = new Material(assetManager,
          "Common/MatDefs/Misc/Unshaded.j3md");  // create a simple material
        mat.setColor("Color", ColorRGBA.Blue);   // set color of material to blue
        geom.setMaterial(mat);                   // set the cube's material
        rootNode.attachChild(geom);              // make the cube appear in the scene
    }
}

Main.scala

import coz.Application


object Main extends App
{
    var app = new Application();
    app.start();
}

make.sh

SRC=`echo Main.scala Application.scala`
