[SOLVED] JoystickConnectionListener not working

Barna · September 23, 2024, 2:02pm

I am newbie with JMonkeyEngine 3.6 and i am learning with the tutorials.

I am successfully using a Gamepad F310 button, but the connect/disconnect listener is not working :
hello_input (listening-for-joystick-connections)

When i unplug the gamepad, i get this looped message in console:

INFOS: Failed to poll device: Failed to poll device (8007000c)

Can you help me please ?

Note that JoystickConnectionListener only works in LWJGL3, as discussed here:

Barna · September 23, 2024, 3:26pm

Thanks for the quick reply.

How do I know if I am in LWJGL3 ?
Is this the value returned by the settings.getRenderer() method ? In my application, the returned value is LWJGL-OpenGL3. Am i in LWJGL3 ?

By looking at your project dependencies.

When you setup the project, you set which version of lwjgl you use by which of the JME libraries you pick (or it was set for you). We don’t know how you’ve set your project up and so can’t really provide a more detailed response than that.

Barna · September 23, 2024, 3:56pm

OK, I think you’re talking about JME IDE.
In fact, i use directly the JME 3.6 libraries with Eclipse IDE. So I will use JME IDE and i will come back to you later.
Thanks!

fba · September 23, 2024, 4:15pm

Then check which of these libraries you’re using:

jme3-lwjgl-3.6.0-stable.jar —> LWJGL2
jme3-lwjgl3-3.6.0-stable.jar —> LWJGL3

This file is not in the library I downloaded from github :
https://github.com/jMonkeyEngine/jmonkeyengine/releases
I choose jME3.6.1-stable.zip.

Inside, i am a file lib\jme3-lwjgl.jar.

While not really about your particular problem. You should move from… Ant? to Gradle. It will be much easier in the long run. You don’t need to manage dependencies by hand. Or even partner Apache Ivy with Ant then… Well, totally recommend to skip that and go straight to Gradle.

Since you want to use Eclipse, jMonkeyEngine | Quick Start, use that to get your Gradle project going.

Barna · September 23, 2024, 5:49pm

OK. I’ll use Gradle, hoping the dependencies are the right ones. I’ll come back later.

Thanks for your interest in my problem.

Barna · September 25, 2024, 12:50pm

I downloaded the gradle project created with your online tool. I imported the project into Eclipse. But JoystickConnectionListener is still causing an error in the console when I unplug the GamePad.

According to your information, if I get these error messages in the console with JoystickConnectionListener, it’s because the library uses LWJGL2 and not LWJGL3. Is this correct? Please tell me if I’m wrong.

I have tried successfully :

To download (from Github) the Java archives used with Eclipse
To use the JME SDK IDE (without Eclipse)
Import a Gradle project with Eclipse

But i always get the same error with JoystickConnectionListener.

How to access a distribution that uses LWJGL3 (for a desktop application) ?

The code i use :

public class Test extends SimpleApplication {

    public static void main(String[] args) {
        Test app = new Test();
        app.setShowSettings(false);
        AppSettings appSettings = new AppSettings(true);
        appSettings.setUseJoysticks(true);
		app.setSettings(appSettings);
        app.start();
    }

    @Override
    public void simpleInitApp() {
        Box b = new Box(1, 1, 1);
        Geometry geom = new Geometry("Box", b);
        Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
        mat.setColor("Color", ColorRGBA.Blue);
        geom.setMaterial(mat);
        rootNode.attachChild(geom);
        
        inputManager.addJoystickConnectionListener(new JoystickConnectionListener() {
            @Override
            public void onConnected(Joystick joystick) {
                System.out.println("Joystick connected: " + joystick.getName());
            }
            @Override
            public void onDisconnected(Joystick joystick) {
                System.out.println("Joystick Disconnected: " + joystick.getName());
            }
        });
    }

}

Your project should be using LWJGL 3 now.

Barna · September 25, 2024, 3:55pm

So why do I get an error when I use a JoystickConnectionListener ?

tonihele · September 25, 2024, 4:35pm

Is it the same exact error message you are getting? And please post the startup log from your application that we can be absolutely sure you are on LWJGL 3

Barna · September 25, 2024, 5:58pm

Yes, i see. It’s LWJGL 2.9.5 !?!

Wherever that’s coming from, it is definitely NOT the build.gradle file that you posed.

Barna · September 25, 2024, 6:20pm

Of course , it is !!! I only have one ‘gradle’ project. It’s not a mistake.

The gradle project obtained from https://jmonkeyengine.org/start/ and imported with Eclipse 2024-06 (4.32) !

tonihele · September 25, 2024, 6:24pm

But does Eclipse treat it as a Gradle project or did you have the old Ant stuff there to mess with Eclipse?

Or try running your project from the command line with gradlew run. Hopefully you have this file.

pspeed · September 25, 2024, 6:28pm

You may have a lot of reasons to BELIEVE that’s the gradle file you are running… but it is 100% not the gradle file that you are running.

Barna:

It says you are using 3.7.0-beta1.2.2 of JME with lwjgl2.

But your build.gradle file says:

And:

Ergo, not the same build.gradle file that is being used to run.

(Also, I sort of would expect the gradle output to look different so I think you might still be running ANT as tonihele suggests.)

I know for sure that you are not using that build.gradle file, for whatever reason.
