[Solved] Gamepad disconnect/re-connect

Ali_RS · May 10, 2019, 5:46am

Maybe adding this check can fix the issue (at least the null pointer exception) for LWJGL3. Not sure if it will recognise it after re-connect so.

if (!glfwJoystickPresent(entry.getKey())) {
    continue;
}

    return String.valueOf(index);
}
@Override
public void initialize() {
    initialized = true;
}
@Override
public void update() {
    for (final Map.Entry<Integer, GlfwJoystick> entry : joysticks.entrySet()) {
        // Axes
        final FloatBuffer axisValues = glfwGetJoystickAxes(entry.getKey());
        for (final JoystickAxis axis : entry.getValue().getAxes()) {
            final float value = axisValues.get(axis.getAxisId());
            listener.onJoyAxisEvent(new JoyAxisEvent(axis, value));
        }
        // Buttons
        final ByteBuffer byteBuffer = glfwGetJoystickButtons(entry.getKey());

Searching google, it seems there is not a controller listener for connect/disconnect in LWJGL3/GLFW.
