I'm using MRTK 2.3.0 trying to catch a "Grip Press" event from the Mixed Reality motion controller.
I've setup the Input Action in the MRTK Toolkit in the Hierarchy of Unity. I've also assigned the action to the controller's grip button in the Controller Definitions. I'm using the following code and made sure the Grip variable is assigned to the Grip Press event. Nothing happens... I'm able to catch touchpad and joystick, menu button press, but not Grip? Why?
According to this documentation: https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/MixedRealityConfigurationGuide.html the Grip should be a "float" as it's designed as single axis (I wonder why, since it's a button and not a trigger...). However, I'm trying to catch the event where I can... not working...
Anyone understand what the heck I'm trying to say here? (sorry, the code below also includes other events that I can catch without a hickup).
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Microsoft.MixedReality.Toolkit.Input;
using Microsoft.MixedReality.Toolkit;
public class TestInput : MonoBehaviour, IMixedRealityBaseInputHandler,
IMixedRealityInputHandler<Vector2>, IMixedRealityInputHandler
{
public MixedRealityInputAction Trigger, Grip, Scroll, Swipe, Joystick, DPad, TouchPadClicked, TouchPadTouched, MenuPressed;
public MixedRealityInputAction DPadUp, DPadDown, DPadLeft, DPadRight, JoystickUp, JoystickDown, JoystickLeft, JoystickRight;
private bool TouchpadPressed, MenuButtonPressed, GrabPressed, TouchDialogPadPressed, TouchpadClicked, Thouchpadtouched,
ThumbstickActive, ThumbstickPressed, VRManipulationStarted, ScrubStarted, PlayPause = false;
private void OnEnable()
{
IMixedRealityInputSystem inputSystem;
if (MixedRealityServiceRegistry.TryGetService<IMixedRealityInputSystem>(out inputSystem))
{
inputSystem?.RegisterHandler<IMixedRealityBaseInputHandler>(this);
inputSystem?.RegisterHandler<IMixedRealityInputHandler<Vector2>>(this);
inputSystem?.RegisterHandler<IMixedRealityInputHandler>(this);
inputSystem?.RegisterHandler<IMixedRealityInputHandler<float>>(this);
}
}
private void OnDisable()
{
IMixedRealityInputSystem inputSystem;
if (MixedRealityServiceRegistry.TryGetService<IMixedRealityInputSystem>(out inputSystem))
{
inputSystem?.UnregisterHandler<IMixedRealityBaseInputHandler>(this);
inputSystem?.UnregisterHandler<IMixedRealityInputHandler<Vector2>>(this);
inputSystem?.UnregisterHandler<IMixedRealityInputHandler>(this);
inputSystem?.UnregisterHandler<IMixedRealityInputHandler<float>>(this);
}
}
public void OnInputChanged(InputEventData<Vector2> ed)
{
Debug.Log("InputChanged");
if (ed.MixedRealityInputAction == DPad)
{
Debug.Log("Touched Touchpad at:" + ed.InputData.x.ToString() + "," + ed.InputData.y.ToString());
}
if (ed.MixedRealityInputAction == Joystick)
{
Debug.Log("Touched Joystick at:" + ed.InputData.x.ToString() + "," + ed.InputData.y.ToString());
}
}
public void OnInputChanged(InputEventData ed)
{
if (ed.MixedRealityInputAction == MenuPressed)
{
Debug.Log("Menu button pressed");
//ActionText.text = "Grab pressed";
}
}
public void OnInputChanged(InputEventData<float> ed)
{
Debug.Log("Float Changed");
if (ed.MixedRealityInputAction == Grip)
Debug.Log("Grab Pressed");
}
Ok... I got this..... It's a BUG in MRTK.
I have 18 actions defined (when you have DPad left, up, down etc it goes by fast!).
When I try to assign my MixedRealityInputAction to an InputAction in the Inspector, when I try to select GrabPressed (which is the 18th action), I get
IndexOutOfRangeException: Index was outside the bounds of the array.
Microsoft.MixedReality.Toolkit.Input.Editor.InputActionPropertyDrawer.OnGUI
Therefore the action does not work....
I tried to use another InputAction instead and assign it to the grab button (I used Select in this case) and it works like a charm....
Beware....
Try
Input.GetAxisRaw(ControllerMappingLibrary.AXIS_11) > 0 || Input.GetAxisRaw(ControllerMappingLibrary.AXIS_12) > 0;
AXIS_11 is grip press for the left controller while 12 is for the right controller

I am trying to get a label widget to update when a key is pressed. For some reason cannot get the label text to update, even though the Gtk thread correctly registers the key press (eg, writes the key to console). This is mono 4.4.0 and gtk-sharp 2.12 on macos.
public MainWindow() : base(Gtk.WindowType.Toplevel)
{
Build();
this.KeyPressEvent += ToddlerKeyPressEventHandler;
}
public void ToddlerKeyPressEventHandler (object o, Gtk.KeyPressEventArgs args) {
Gtk.Application.Invoke(delegate {
string letter = args.Event.Key.ToString();
this.letterLabel.Text = letter;
Console.WriteLine(letter);
this.letterLabel.QueueDraw();
});
}
I think you're missing an attribute. Try this:
[GLib.ConnectBeforeAttribute]
public void ToddlerKeyPressEventHandler (object o, Gtk.KeyPressEventArgs args)
{
letterLabel.Text = args.Event.Key.ToString ();
}
Bear in mind that if the event handler is hooked up to the label widget this won't work unless you also ensure that the "Selectable" property for that label widget is set to true (checked).
My monogame game has stopped responding to mouse clicks. Prior to version 3.5, this was working fine. Here's how I'm currently getting the input:
protected override void Update (GameTime game_time)
{
Mouse_Input (game_time);
}
void Mouse_Input(GameTime game_time)
{
mouse_current = Mouse.GetState();
if (mouse_current.LeftButton == ButtonState.Pressed)
{
// click
}
}
Setting breakpoints in the function reveals all the code is being hit, but LeftButton is always ButtonState.Released.
I've tried with both a wired mouse and the trackpad. Keyboard input is working fine. Anyone else running into this?
I always use this way.
MouseState currentMouseState;
MouseState oldMouseState;
public bool checkClick()
{
oldMouseState = currentMouseState;
currentMouseState = Mouse.GetState();
if (Visible)
{
if (currentMouseState.LeftButton == ButtonState.Pressed && oldMouseState.LeftButton == ButtonState.Released)
{
return true;
}
}
}
If you want to check if the Mouse clicks on a Rectangle (Hud elements for example)
public bool checkClickRectangle(Rectangle rec)
{
oldMouseState = currentMouseState;
currentMouseState = Mouse.GetState();
if (Visible)
{
if (rec.Contains(new Vector2(Mouse.GetState().X, Mouse.GetState().Y)) && currentMouseState.LeftButton == ButtonState.Pressed && oldMouseState.LeftButton == ButtonState.Released)
{
return true;
}
}
}
This was actually a not a problem with Monogame, but a problem in my game logic that was very difficult to track down.
After upgrading to 3.5, I had to reconfigure how my Texture2D's were being loaded, which also meant refactoring some classes. I ended up with a class within a class which were both inheriting from Game.
public class Brush_Control : Game
{
public class Tile : Game
{
Process of elimination narrowed the search to this class. I believe this caused an infinite loop that interfered with the input somehow, but without throwing an error or causing an obvious freeze.
Removing the inner Game reference as a parent fixed the problem, and it turns out I no longer need to have it there anyway.
I'm working on a project for an intro to programming class, and I've run into a slight problem. We're making a side scroller, and I'm working on the score counter right now. My issue is that when I try to create a reference to the counter class in anything other than the act method(called once every frame) I get a null pointer exception error. You can download the zip file with my code in it here if you want to take a look.
EDIT:
Here's the offending code:
public class HeroMissile extends Missiles
{
/**
* Act - do whatever the HeroMissile wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
public void act()
{
move(8);
remove();
}
public void remove() {
if(isTouching(Drone.class)) {
removeTouching(Drone.class);
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
addScore();
return;
}
}
public void addScore() {
City cityWorld = (City) getWorld();
**Counter scoreCounter = cityWorld.getCounter();**
scoreCounter.add(1);
}
}
You are calling getWorld() [in addScore()] after you removed yourself from the world. In this case, getWorld() will return null, so you will get a null pointer exception. Try changing the order in remove() to add the score before you remove yourself from the world.
I am having a class inherited from QGraphicsScene. I have a mouseMoveEvent in this class. Based on the mouse move I am sending the co ordinates via signal to the main window. I have multiple GraphicViews in main window. Based on the scene from which the signal is received I am display the scene co ordinates using QGraphicsTextItem.
The problem is when I move out of the scene area I am unable to hide the QGraphicsTextItem.
Can someone give me a work around for this?
Class Scene::QGraphicsScene
{
void MouseMoveEvent(QGraphicsSceneMouseEvent *Event)
{
int XPos = event.x();
int YPos = event.y();
emit SignalPos(XPos,YPos);
}
}
//In Main Window
connect(scene1,SignalPos(int,int),this,SlotPos1(int,int);
//Similarly for scene2,scene3,scene4
void MainWindow::SlotPos(int X, int Y)
{
m_qgtxtItemX.setText(QString::x);
//I want to hide this once I am out of scene.It is a member variable. I tried
//taking local variable but it didn't work.
//Similarly for y and other slots
}
Install an event filter on the scene.
scene1->installEventFilter(this);
then implement the method in the class that is referenced by "this":
bool eventFilter(QObject *watched, QEvent *event) {
if (event->type() == QEvent::Leave)
{
qDebug() << "Mouse left the scene";
}
return false;
}
Just tried it and it worked! If you are installing the event filter on more than one object, please use "watched" to differentiate between them.
Best,
I have a strange problem with an AlphaAnimation. It is supposed to run repeatedly when an AsyncTask handler is called.
However, the first time the handler is called in the Activity, the animation won't start unless I touch the screen or if the UI is updated (by pressing the phone's menu button for example).
The strange part is that once the animation has run at least once, it will start without problem if the handler is called again.
Here's what the code looks like:
// AsyncTask handler
public void onNetworkEvent()
{
this.runOnUiThread(new Runnable() {
#Override
public void run()
{
flashScreen(Animation.INFINITE);
}
});
}
// Called method
private void flashScreen(int repeatCount)
{
final View flashView = this.findViewById(R.id.mainMenuFlashView);
AlphaAnimation alphaAnimation = new AlphaAnimation(1, 0);
alphaAnimation.setRepeatCount(repeatCount);
alphaAnimation.setRepeatMode(Animation.RESTART);
alphaAnimation.setDuration(300);
alphaAnimation.setInterpolator(new DecelerateInterpolator());
alphaAnimation.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation)
{
flashView.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animation animation)
{
flashView.setVisibility(View.GONE);
}
#Override
public void onAnimationRepeat(Animation animation) { }
});
flashView.startAnimation(alphaAnimation);
}
I have noticed that runOnUIThread isn't necessary (same results occur if I don't use it), but I prefer keeping it as I'm not on the UI thread.
Any ideas on what could cause this?
A little more research showed that my problem was the same a this question:
Layout animation not working on first run
The flashView's visibility was set to GONE by default (causing the Animation not to start immediately as the View had never been rendered), so I just need to set it to INVISIBLE before calling flashView.startAnimation()
If setting the View to VISIBLE won't work, as was in my case, it helped for me to call requestLayout() before starting the Animation, like so:
Animation an = new Animation() {
...
view.requestLayout();
view.startAnimation(an);
In my case, my View was 0dip high which prevented onAnimationStart from being called, this helped me around that problem.
This worked for me:
view.setVisibility(View.VISIBLE);
view.startAnimation(animation);
I had to set the view to VISIBLE (not INVISIBLE, neither GONE), causing the view renderization needed to animate it.
That's not an easy one. Till you got a real answer : The animation start is triggered by onNetworkEvent. As we don't know the rest of the code, you should look there, try to change onNetworkEvent by an other event that you can easily identify, just to debug if the rest of the code is ok or if it's just the trigger that is responsible for it.
May be it will help someone, because previous answers not helped me.
My animation was changing height of view (from 0 to it's real height and back) on click - expand and collapse animations.
Nothing worked until i added listener and set visibility to GONE, when animation ends:
collapseAnim.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
view.setVisibility(View.GONE);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
And when expand just set it to VISIBLE before animation:
view.setVisibility(View.VISIBLE);
view.startAnimation(expandAnim);
