Cannot rumble two motors on gamepad

Troubleshooting General Help
1

Hello,

I noticed the joystick class only allowed one motor to rumble, so I tried to use JInput directly, I dont feel any difference in my hands, just as if only the right motor was turning (also it does not turns smoothly, it feels jerky)

I tested the gamepad with the control pannel tester, and both motors work, so I am wondering if JInput really works at all


    ControllerEnvironment cEnvironment = ControllerEnvironment.getDefaultEnvironment();
        Controller[] cControllers = cEnvironment.getControllers();

        if (cControllers.length>0)
        {
            for (int i = 0; i < cControllers.length; i++) 
            {
                  if (cControllers[i].getType() == Controller.Type.GAMEPAD) 
                  {
                      System.out.println ("Controller Name: " + cControllers[i].getName()+" Type: " + (cControllers[i].getType())+" Rumble: " + ((cControllers[i].getRumblers().length > 0) ? "Yes" : "No"));

                      for (int o = 0; o < cControllers[i].getRumblers().length; o++) 
                      {
                          System.out.println ("- Rumbling Axis: " + cControllers[i].getRumblers()[o].getAxisName());
                          cControllers[i].getRumblers()[o].rumble(1.0f);
                          Thread.Sleep(5000);
                          cControllers[i].getRumblers()[o].rumble(0.0f);
                          Thread.Sleep(2000);
                      }
                  }
            }
        }

any advice ?

thanks

I saw the post when it was on the other thread, too… I think none of us know much about JInput issues which is why it wasn’t answered there.

I don’t know if JInput has a forum or mailing list or whatever… but it might be worth checking. Not sure any of us will be able to help here as we are just JInput users… and not even very aware users.

already checked, not beeing updated since 2013, wondered if JInput was still maintained…
well thought it was better to create a fresh thread, let’s hope someone had the same problem …

which gamepad are you using on which os ?
Do you have the same issue with others game pad or on another os ?
Maybe you can add an issue on the git page : GitHub - jinput/jinput: Java library for accessing input devices and hope someone will fix it.

I submited an issue, but it has id #2, like nobody ever submited anything on jinput github

anyway thanks for the tip

As an additional note, on some gamepads the rumblers don’t work at all (xbox controller i think was one of them). And for linux it think it was required to manually set some permissions.

mine works, it is just jinput that does not rumble the left motor

Nice to hear, going to try it quite soon again. XBox wireless on your side?
