Hello.
Does JInput send an event when a key is released??
basicly I wan’t to know if this check is valid:
m_keyboard.poll();
m_keyboardQueue = m_keyboard.getEventQueue();
Event event = new Event();
while( m_keyboardQueue.getNextEvent(event))
{
float data = event.getComponent().getPollData();
if(data != 0.0f )
{
//Key is down, this check will work for sure
}
else
{
//Key was released, does this work??
}
}
Hi
try it :), but yes, it should raise an event when ever a components value changes.

Thnx.
I will make up for my laziness and post my resultning keyboad class :
package Input;
import java.util.HashMap;
import net.java.games.input.Component;
import net.java.games.input.Controller;
import net.java.games.input.ControllerEnvironment;
import net.java.games.input.Event;
import net.java.games.input.EventQueue;
import net.java.games.input.Keyboard;
import net.java.games.input.Component.Identifier;
import net.java.games.input.Component.Identifier.Key;
import net.java.games.input.Controller.Type;
public class CKeyboard
{
Keyboard m_keyboard;
EventQueue m_keyboardQueue;
HashMap<Identifier, Boolean> m_keyDown;
public CKeyboard()
{
Init();
}
private void Init()
{
Controller[] inputDevices = ControllerEnvironment.getDefaultEnvironment().getControllers();
m_keyboard = null;
for( Controller c : inputDevices)
{
if( c.getType() == Type.KEYBOARD)
{
m_keyboard = (Keyboard)c;
break;
}
}
if( m_keyboard != null)
{
m_keyDown = new HashMap<Identifier, Boolean>();
for( Component c : m_keyboard.getComponents())
m_keyDown.put(c.getIdentifier(), false);
}
}
public void capture()
{
if( m_keyboard == null )
return;
m_keyboard.poll();
m_keyboardQueue = m_keyboard.getEventQueue();
Event event = new Event();
while( m_keyboardQueue.getNextEvent(event))
{
float data = event.getComponent().getPollData();
if(data != 0.0f )
{
m_keyDown.put(event.getComponent().getIdentifier(), true);
}
else
{
m_keyDown.put(event.getComponent().getIdentifier(), false);
}
}
}
public boolean isKeyDown( Key k)
{
return m_keyDown.get(k);
}
}
I made a quick test and it seems to work fine.
I haven’t worked with HasMaps before, they are quite nice
I also have a question about mouse input.
I can’t seem to get the correct relative mouse position.
if I use event queue for the mouse it almost works, but when I hold my mouse still I still get realtive movemnt of atleast 1.0f;
if I use this approatch:
m_mouse.poll();
m_deltaMouse.x = m_mouse.getX().getPollData()
m_deltaMouse.y = m_mouse.getY().getPollData()
the values are constant 0.0 in both X and Y.
I use windows xp.
my test app looks like this:
public static void main( String[]args)
{
JFrame f = new JFrame("This is a test");
f.setSize(1024, 768);
Container content = f.getContentPane();
content.setBackground(Color.white);
f.addWindowListener(new ExitListener());
f.setVisible(true);
while( true )
{
Input.getInstance().capture();
//Keyboard works fine
if( Input.getInstance().getKeyboard().isKeyDown(Identifier.Key.Q))
{
System.exit(0);
break;
}
//event mode work's poor, "imidate" mode don't work at all"
System.out.println("delta mouse x : "+Input.getInstance().getMouse().getDelta().x );
System.out.println("delta mouse y : "+Input.getInstance().getMouse().getDelta().y );
//Mouse has no dead zone....
System.out.println("\ndead zone x : "+Input.getInstance().getMouse().getDeadZone().x );
System.out.println("\ndead zone y : "+Input.getInstance().getMouse().getDeadZone().y );
}
}
}
class ExitListener extends WindowAdapter {
public void windowClosing(WindowEvent event)
{
System.exit(0);
}
}
btw: I don’t check mouse and keyboard poll in the same loop, does the getEventQueue() “steal events”, feels likt that’s not the case ???
