title: How to flush all input events in jMonkey
body: <p>My game takes around a minute to load in android till the first screen appears. Till the time its loading, jmonkey’s input manager seems to queue all inputs which results in nasty behavior(automatic button clicks) as soon as my first nifty screen loads. </p>
  
  <p>Same happens when the scene loads(which again takes a while on pressing the appropriate nifty button). This happens despite the fact that I set mappings and listeners in the last App State which loads.</p>
  
  <p>Is there a way to flush all previous input which I can call just before and after adding listeners to input manager?</p>
  
  <p>I dont do much work in update() and initialize of my appstates but some functions (reinitialize()) which I call on nifty's OnClick(), loads all the scene and models in the scene garph so it takes a while. Here is a pseudo code of my application</p>
  
  <pre><code>In Main.java {
  
  // Nothing in SimpleUpdate()
  
  // This app state contains
   stateManager.attach(new MainMenuAppState());
  }
  In MainMenuAppState.java  implements ScreenController  {
  
  initialize() {
          niftyDisplay = new NiftyJmeDisplay(app.getAssetManager(), app.getInputManager(), app.getAudioRenderer(), app.getGuiViewPort());
  
          // Create a new nifty GUI object
          nifty = niftyDisplay.getNifty();
  // attach a couple of more app states which also has nothing significant in update loop
  
  // do some good computation
  // attach 5 new APP STATES which does not have anything significant in update()
  
  display the appropriate screen of nifty
  }
  onClick() {
   nifty.gotoScreen(“loadScreen”);
  
  // appstate previously attached. they dont have anything significant in update.
  // They have significant initialize methods.
  app.enqueue(
              rgas.reInitialize(time,cameraLoc,cameraRot);
              maes.reInitialize(qId); // loads all the scene and models on screen
              nifty.gotoScreen(“hudScreen”);
              nifty.getScreen(“hudScreen”).findElementByName(“ConfirmModuleButton”).setFocus();
              ppes.reInitialize();   // this contains input mappings
  
  );
  }
  }
  </code></pre>
