Trouble with tutorial 4 (Solved)

Troubleshooting General Help
1

I’ve been going through the tutorials and have been successful so far. However, I have no idea why the simpleUpdate function in the 4th tutorial doesn’t work. The function doesn’t seem to even run. While the visuals work and I can move the camera, the cube doesn’t rotate.



The code:

[java]

package jme3test.helloworld;



import com.jme3.app.SimpleApplication;

import com.jme3.material.Material;

import com.jme3.math.ColorRGBA;

import com.jme3.math.Quaternion;

import com.jme3.math.Vector3f;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;



public class HelloLoop extends SimpleApplication{

public static void main(String[] args){

HelloLoop app = new HelloLoop();

app.start();

}



protected Geometry player;



@Override

public void simpleInitApp(){

Box b = new Box(Vector3f.ZERO, 1.0f, 1.0f, 1.0f);

player = new Geometry(“blue cube”, b);

Material mat = new Material(assetManager,

“Common/MatDefs/Misc/Unshaded.j3md”);

mat.setColor(“Color”, ColorRGBA.Blue);

player.setMaterial(mat);

rootNode.attachChild(player);

}



@Override

public void simpleUpdate(float tpf){

player.rotate(0, 2*tpf, 0);

}

}

[/java]



I’ve copied the tutorials code directly (it didn’t work) and searched google for similar problems with no success.



Edit: I apologize for making a stupid mistake and posting it. I had made a new package and didn’t delete the existing package. Anyway, the solution was to delete the other package.

To be exact: the solution was setting the main class of the project to the correct new class, you only provoked the auto-detection of main classes by deleting the other one, leaving just the new one to start.
