I have the following event listener:
viewer.camera.moveStart.addEventListener(function(removeextra) {
// the camera started to move
clearoriginal();
});
viewer.camera.moveEnd.addEventListener(function(addback) {
// the camera stopped moving
getresults();
});
How can I remove these event listeners? I do not know the syntax.I tried with the following it does not work.
viewer.camera.moveStart.removeEventListener(removeextra);
viewer.camera.moveEnd.removeEventListener(addback);
I looked into Cesium and I think you might rewrite them like this
viewer.camera.moveStart.addEventListener(clearoriginal);
viewer.camera.moveEnd.addEventListener(getresults);
// then to remove
viewer.camera.moveStart.removeEventListener(clearoriginal);
viewer.camera.moveEnd.removeEventListener(getresults);
viewer.camera.moveEnd.removeEventListener('click',
getresults,// pass the method which you add
false
);
addEventListener() and removeEventListener() are not present in older browsers. You can work around this by inserting the following code at the beginning of your scripts, allowing the use of addEventListener() and removeEventListener() in implementations that do not natively support it. However, this method will not work on Internet Explorer 7 or earlier, since extending the Element. a prototype was not supported until Internet Explorer 8.

I'm using InputSystem.EnhancedTouch for my game and I have a few buttons that are available through UI Elements. When I click on the UI Elements buttons it activates the InputSystem thus creating a bad experience. I want to filter out all the InputSystem.EnhancedTouch events that come through UI.
TL;DR - I want UI Elements to block InputSystem.EnhancedTouch events from triggering
I have found quite some resources but nothing really works. Unity and some other people say to use EventSystem.current.IsPointerOverGameObject but it doesn't work and throws the following warning(I think this is meant to work with normal input only, not enhanced one)
I have tried a few other solutions such as UIDocument.rootVisualElement.panel.Pick or EventSystem.current.RaycastAll but nothing seems to work, or return any consistent data that can be used.
InputSystem.EnhancedTouch binding
private void Awake()
{
EnhancedTouchSupport.Enable();
Touch.onFingerDown += OnFingerDown;
Touch.onFingerMove += OnFingerMove;
Touch.onFingerUp += OnFingerUp;
}
I know that this question has already been asked here twice, but the answers did not fix my problem. I need to enable spatial mapping on runtime. After scanning my environment I want to disable it, or hide at least the visualization of polygons, so I can save some fps. But by disabling spatial mapping I still want to have the colliders of my environment.
What I tried:
1. This example from this post did nothing.
if (disable){
// disable
MixedRealityToolkit.SpatialAwarenessSystem.Disable();
}
else
{
// enable
MixedRealityToolkit.SpatialAwarenessSystem.Enable()
}
2. Trying to disable the visualization gives me every time a nullreference. I guess GetObservers is giving null back or maybe meshOserver is null:
foreach(var observer in MixedRealityToolkit.SpatialAwarenessSystem.GetObservers())
{
var meshObserver = observer as IMixedRealitySpatialAwarenessMeshObserver;
if (meshObserver != null)
{
meshObserver.DisplayOption = SpatialAwarenessMeshDisplayOptions.None;
}
}
3. The example given by mrtk in there SpatialAwarenessMeshDemo scene, shows how to start and stop the observer. By starting everything starts fine but after suspending and clearing the observers the whole spatial map disappears, so my cursor does not align to my environment. So this is not what I need.
SpatialAwarenessSystem.ResumeObservers(); //start
SpatialAwarenessSystem.SuspendObservers();//stop
SpatialAwarenessSystem.ClearObservations();
What I have right now:
My Spatial Awareness Profile looks like this:
My code starts the spatial mapping with ResumeObservers, the foreach-loop gives me a nullreference and SuspendObserver is comment out, because it disables the whole spatial map thing:
if (_isObserverRunning)
{
foreach (var observer in SpatialAwarenessSystem.GetObservers())
{
var meshObserver = observer as IMixedRealitySpatialAwarenessMeshObserver;
if (meshObserver != null)
{
meshObserver.DisplayOption = SpatialAwarenessMeshDisplayOptions.None;
}
}
//SpatialAwarenessSystem.SuspendObservers();
//SpatialAwarenessSystem.ClearObservations();
_isObserverRunning = false;
}
else
{
SpatialAwarenessSystem.ResumeObservers();
_isObserverRunning = true;
}
Question: How do I start and stop spatial mapping the right way, so that I can save some performance and still have the colliders of the spatial map to interact with.
My specs:
MRTK v2.0.0
Unity 2019.2.0f1
Visual Studio 2017
!--Edit--inlcuding-Solution--!
1. With option #1 I was wrong. It does what its meant for, but I used it the wrong way. If you disable for example SpatialAwarenessSystem while running the spatial mapping process, it disables the whole process including the created spatial map. So after that you cant interact with the invironment.
2. What worked for me was using for the start ResumeObservers() in combination with setting display option to visible and for stopping spatial mapping the method SuspendObservers() in combination with display option none.
3. The Nullreference if fixed by rewritting and casting to IMixedRealityDataProviderAccess:
if (CoreServices.SpatialAwarenessSystem is IMixedRealityDataProviderAccess provider)
{
foreach (var observer in provider.GetDataProviders())
{
if (observer is IMixedRealitySpatialAwarenessMeshObserver meshObs)
{
meshObs.DisplayOption = option;
}
}
}
4. Performance: To get your fps back after starting an observer, you really need to disable the system via MixedRealityToolkit.SpatialAwarenessSystem.Disable();, but this will of course disable also the spatial map, so you cant interactive with it anymore.
#Perazim,
The recommendation is based on your option #3. Call ResumeObservers() to start and SuspendObservers() to stop. There is no need to call ClearObservations() unless you wish to have them removed from your scene.
The example calls ClearObservations() to illustrate what was, at the time, a new feature added to the Spatial Awareness system.
Please file an issue on GitHub (https://github.com/microsoft/MixedRealityToolkit-Unity/issues) for #1 (failure of Enable() and Disable() to impact the system). Those methods should behave as advertised.
Thank you!

I am running an E2E test for an Angular 7.x app. The test runs straight forward on my local machine. But when I push it on the repo (GitLab), then pipeline fails and throws following error:
USER PROFILE - Check and change PROFILE
- Failed: element not interactable
(Session info: chrome=71.0.3578.80)
(Driver info: chromedriver=2.45.615279 (12b89733300bd268cff3b78fc76cb8f3a7cc44e5),platform=Linux 4.14.74-coreos x86_64)
Test Case:
it('USER PROFILE - Check and change PROFILE', () => {
page.navigateTo();
browser.sleep(1000);
expect(page.getProfileEditTagName()).toMatch('app-edit-profile');
expect(element(by.className('logged-as')).getText()).toBe( testEmail );
browser.actions().mouseMove( element.all( by.id('editIcon-salutation') ).get(0)).click().perform().then(function () {
browser.sleep(4000);
element( by.className('mat-select-arrow') ).click().then(function () {
browser.actions().mouseMove( element.all(by.className('option-value mat-option')).get(0)).click().perform();
browser.sleep(1000);
browser.actions().mouseMove( element.all( by.id('saveButton-salutation') ).get(0)).click().perform();
browser.sleep(1000);
});
});
});
navigateTo() is just a method in profile.po.ts:
navigateTo() {
browser.get('/profileComponentUrl');
}
What's confusing me and where I even can't localize the bug or what's wrong, is that it works fine locally. But once I push to repo, then it fails exactly at that test case. Any Hint please?
The reason element is not interactable could be - performing an action on hidden or obscured element.
You can try -
1. add sleep after by.className('mat-select-arrow') ).click(), as I can see you have not added any waits there.
2. Try to check if you running the test on your local and Jenkins machine with same screen resolution. (this could be the reason of obscured element)
I'd recommend to:
Enable the stacktrace in protractor config: new SpecReporter({ spec: { displayStacktrace: true } }) so you can see exactly what element is throwing the error. This won't solve it but at least should point you in the right direction.
Then if you're using tabs, buttons or other elements that hide/show/disable/enable or change the DOM view, you add a browser.sleep(100) after calling a .click()
I had a same kind of problem and I found this.
I copy pasted that (and some other minor tweaks for example force clicking on previous page in for-loop) and it worked. I believe that the browser.driver.manage().window().maximize(); was part of the solution.
One reason which i figure out is the scroll issue. You need to check the element is displaying properly or not. It may be hidden. So use scrollToTop/scrollToElement/scrollToElementView etc. You can write different scroll methods which suites the condition better.
Another reason is the locator. Try to change the locator, do not trim the locator too much. Just try with full body css locator, if it works then trim properly. Some time in chrome console it may work but not with the test case.
I'm playing with Firebase as an alternative to a local Mongo store, for the time being.
I've followed various tutorials, however they are all for older versions of ES6. I've tried to tweak them to v14 and ES6 but, well, no errors but no data!
Some code:
var Rebase = require('re-base');
var base = Rebase.createClass('https://reactathon.firebaseio.com/days');
...
componentDidMount() {
console.log('ExampleComponent Mounted');
base.bindToState('days', {
context: this,
state: 'days',
asArray: true
});
console.log(this.state.days[0]);
}
The console simply logs undefined. I've tried the base URL with and without /days. I've tried getting the data as an object instead of an array. I have a feeling I'm simply pointing at the wrong thing.
Any thoughts?
Cheers.
bindToState is an asynchronous method so it's going to take some time to set up that listener. You're logging before the listener has been set up. As Jacob mentioned in his comment, move your log to your render method and then once your state is bound to Firebase your component will re render and you should see your data.
I'm trying to handle the event when the close button of a Window is clicked:
// View Code
#Override
public void attachWindowListener(WindowListener listener) {
window.addWindowListener(listener);
}
// Presenter code
view.attachWindowListener(new WindowListener(){
public void windowHide(WindowEvent we) {
GWT.log("Window Event - Processing fields");
processFields();
}
});
However, the windowHide function seems to be not executed since I can't see the log I placed there.
How to properly handle that event?
How about
Window.addCloseHandler(
new CloseHandler<Window>()
{
public void onClose( CloseEvent<Window> windowCloseEvent )
{
// Do your worst here
}
} );
I usually put this in onModuleLoad() in my EntryPoint class.
Cheers,
Based on the information provided I would guess that either a.) the events you think are firing do not fire for the Window component (even if it seems like they should) or b.) the events are firing but in a different order than you expect.
For example, it's possible that a BrowserEvent or some other event is firing first as the window is being closed and the Window object's WindowEvent never fires. According to the API docs for GXT 2.x, the WindowEvent will fire on hide and deactivate but it does not specify that it fires on close. The GXT 3.0.x API doc is less clear on this point but I would assume the same behavior. Unfortunately Sencha does not provide good documentation on what events fire for a given component and in what order.
With that said, I have had some luck working through similar issues to this by using a debug class which outputs all the events on a component to which it is attached. This may shed some light on which events are firing and their order of execution, and you may find an optimal event to which you can attach your processFields() method.
For a good example of a debugger class, see this answer from a related post: https://stackoverflow.com/a/2891746/460638. It also includes an example of how to attach the debugger to your component.

This worked:
window.addListener(Events.Hide, new Listener<ComponentEvent>() {
#Override
public void handleEvent(ComponentEvent be) {
// Do stuff
}
});
