Crashes when changing certain graphics options

Troubleshooting graphics
1

I have recently noticed this issue in my jME3 application: when changing antialiasing and attempting to restart the display to apply the new settings, the program crashes. I am not sure whether the antialiasing change alone is the issue, it is simply how I experienced this issue for the first time.



I was able to duplicate the problem with the TestContextRestart demo by adding one line of code. Add the following after settings.setFullscreen(true):



[java]settings.setSamples(4);[/java]



The application crashes with the following error:


Jul 18, 2011 6:24:23 PM com.jme3.app.Application handleError
SEVERE: Uncaught exception thrown in Thread[LWJGL Renderer Thread,6,main]
java.lang.IllegalStateException: The Drawable has no context available.

I have no idea what it means, but I know someone will be able to shed some light on this issue. Thanks.

Thanks, Fixed in SVN.

Hi, when I try to change antialiasing during runtime and restart the display, the screen turns black and nothing else happens.



For example, using HelloLoop demo, if I change antialiasing after 3 seconds, the blue cube is not visible anymore:



[java]package jme3test.helloworld;



import com.jme3.app.SimpleApplication;

import com.jme3.material.Material;

import com.jme3.math.ColorRGBA;

import com.jme3.math.Vector3f;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.system.AppSettings;



/** Sample 4 - how to trigger repeating actions from the main event loop.

  • In this example, we make the player character rotate. /

    public class HelloLoop extends SimpleApplication {



    public static void main(String[] args) throws InterruptedException{

    AppSettings settings = new AppSettings(true);

    HelloLoop app = new HelloLoop();

    app.setSettings(settings);

    app.start();



    Thread.sleep(3000);



    settings.setSamples(4);

    app.setSettings(settings);

    app.restart();

    }



    protected Geometry player;



    @Override

    public void simpleInitApp() {

    /    * this blue box is our player character /

    Box b = new Box(Vector3f.ZERO, 1, 1, 1);

    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);

    }



    /     Use the main event loop to trigger repeating actions. /

    @Override

    public void simpleUpdate(float tpf) {

    // make the player rotate:

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

    }

    }[/java]

Sorry, the question was: is someone else getting problems with changing antialiasing during runtime.

Sometimes instead of the black screen problem, the application closes with a java fatal error and generates an error log, why is this?

thanks

To make this even more complex, I sometimes get a completely new error when changing graphics options with nifty.

Here is my code for restarting the app:

restart();
nifty.resolutionChanged();[/java]
The good thing is the original error seems to be gone for now. :)

Is there a way of reproducing this by any chance?

Yes, the code of HelloLoop modified to change antialising after 3 seconds. The blue cube is not visible after that:



[java]package jme3test.helloworld;

import com.jme3.app.SimpleApplication;

import com.jme3.material.Material;

import com.jme3.math.ColorRGBA;

import com.jme3.math.Vector3f;

import com.jme3.scene.Geometry;

import com.jme3.scene.shape.Box;

import com.jme3.system.AppSettings;

/** Sample 4 - how to trigger repeating actions from the main event loop.

  • In this example, we make the player character rotate. /

    public class HelloLoop extends SimpleApplication {

    public static void main(String[] args) throws InterruptedException{

    AppSettings settings = new AppSettings(true);

    HelloLoop app = new HelloLoop();

    app.setSettings(settings);

    app.start();

    Thread.sleep(3000);

    settings.setSamples(4);

    app.setSettings(settings);

    app.restart();

    }

    protected Geometry player;

    @Override

    public void simpleInitApp() {

    /    * this blue box is our player character /

    Box b = new Box(Vector3f.ZERO, 1, 1, 1);

    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);

    }

    /     Use the main event loop to trigger repeating actions. /

    @Override

    public void simpleUpdate(float tpf) {

    // make the player rotate:

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

    }

    }[/java]

Okay I think it should be fixed now. I was only able to reproduce the last error (No shader objects attached)

It works great! It solved my errors too!

Thanks!! :wink:
