Jinput轮询数据永不更改

Question

I am attempting to create a simple test program to get familiar with the JInput Library for another project. I have tested my controller with the all of the provided test classes and it works as expected. However, when I attempt to poll the controller, all values remain unchanged regardless of my input. Here is the code I am working with:

public class ControllerTest {

 public static void main(String[] args){ //System.out.println("Hello World"); Controller[] ca = ControllerEnvironment.getDefaultEnvironment().getControllers(); Controller gamepad = null; Component[] components = null; EventQueue eventQueue; // Run through the list of available input devices and get the gamepad for(int i = 0; i < ca.length; i ++){ if(ca[i].getType().equals(Controller.Type.GAMEPAD)){ gamepad = ca[i]; } } // Print the name of the controller and its type if(gamepad != null){ System.out.println(gamepad.getName() + ": " + gamepad.getType()); components = gamepad.getComponents(); System.out.println("\\tComponents:"); for(int i = 0; i < components.length; i ++){ System.out.println("\\t\\tComponent #" + i + ": " + components[i].getName() + "\\n\\t\\t\\tIs Relative: " + components[i].isRelative()); } } else{ System.out.println("No gamepad connected"); } while (true){ // If we have no gamepad connected, exit if(gamepad == null){ System.out.println("No Gamepad detected, exiting..."); System.exit(0); } // Poll controller gamepad.poll(); Component[] comp = gamepad.getComponents(); for(int i = 0; i < comp.length; i ++){ StringBuffer buffer = new StringBuffer(); buffer.append(comp[i].getName()); buffer.append(", Value: " + comp[i].getPollData()); System.out.println(buffer.toString()); } try{ Thread.sleep(20); // Sleep before polling again } catch(InterruptedException e){ e.printStackTrace(); } } } 

}

I have been trying to find an answer online, but this library is not very well documented and seems to usually be wrapped in other libraries specific for making games. (The aforementioned project is robotic in nature)

You have to use an EventQueue

player.poll();
        EventQueue queue = player.getEventQueue();
        Event event = new Event();
        while (queue.getNextEvent(event)) {
            Component comp = event.getComponent();
            if (comp.getIdentifier() == Component.Identifier.Button._6){
                if (comp.getPollData() == 1){
                    example
                }

I was consistently getting only zero values using JInput for mouse X and y locations when building a console application like you have shown above. I believe it may be necessary to create a window-focused application of some kind for JInput to work. See here a code example solution and similar issue described.
