Help with creating cube

Troubleshooting General Help
1

Hey, im not to sure im posting this in the right forum so go easy…



I am going through the tutorials given on the Wiki, and after a while on setting up jME on several different platforms i am running it on ubuntu.



The problem is in the first tutorial i cannot get the cube to show!, to be honest im not to sure whether i give the right information when the pop-up comes up before the application is started, here is the code (You will notice its from tutorials 1):



[java]package mygame;



import com.jme3.app.SimpleApplication;

import com.jme3.math.Vector3f;

import com.jme3.material.Material;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.math.ColorRGBA;

import com.jme3.scene.Node;



public class Main extends SimpleApplication

{



public static void main(String args[])

{

Main app = new Main();

app.start();

}



@Override

public void simpleInitApp()

{



Box b = new Box(new Vector3f(-1, 1, 1), 1, 1, 1);

Geometry blue = new Geometry(“Box”, b);

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

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

blue.setMaterial(mat);

rootNode.attachChild(blue);



}



}[/java]



The settings i use before it started are:



640 x 480 - 24 bpp - Disabled - Fullscreen (false) - VSync (false) - LWJGL-OpenGL2



Any help would be greatly appreciated,



Thanks.

I moved you post to the troubleshooting general.



This should work fine, have you got any error in the log? like a compilation error in the shader?

3

Also on Ubuntu, I had to start my first application twice to get it to run… Looked like the first run extracted some opengl-related .so files and then crashed. Seems to happen every time I used a new renderer

4

What’s the crash? Is it an exception or a native crash?

5

Can’t reproduce the error I had now (by deleting the .so files from my workspace at least). It was an exception, and if I remember correctly something about a missing dependency. I’m using a newer nightly build now, but it could also be something with Eclipse…

6

so did it not run at first (but after?) or not at all?

If it runs it ight be that you see nothing due to a missing light(not sure if there is one in simpleapplication)

7

First time I started my application I got the splash screen, I pressed the start button and the program failed with an exception. Then I started the application again and it worked as it was supposed to. Only happened once per renderer, all subsequent runs succeeded.

8

But what was the exception? Something like “no lwjgl in java.library.path”?

Maybe you can post the stack trace?

9

Well that’s the problem, I haven’t been able to reproduce the exception and I can’t remeber exactly what it said. I think it was something similar to “no lwjgl in java.library.path”… I remember seeing a .so file being created in my workspace/ on the first run, if that’s any help.
