Detect the finger leaves the scene

Hi all

I have an object in my scene which can be dragged around. He listens to event mouse_down and begins after the mouse/finger on each mouse_move event until he recorded a mouse_up event.

How can I detect when the user's finger leaves the side of the screen? Currently, if a user drags on the side of the screen and raises their finger, no mouse_up case is never raised and the subject thinks it's still inappropriate. Thus, there is a mouse_leave event which should do what I want, but seems not to relax.

Ideally, I'd like that behavior, for example the browser - movement still works on the bezel, and if the user swipes too far the application can sign up for an event and act as if the finger was lifted.

Please let me know if anyone can suggest a solution or if it is simply not possible in the air.

Thank you
Brandon

I found the solution to this problem, and as it is the spirit in the forums, I will share my solution for future use.

The problem is that MouseEvents are not triggered properly when moving outside the [0,0] to [1 023 599] screen coordinates. The solution is to use the multipoint touch input rather than detect mouse events.

(1) import the right classes:

flash.ui import. *;

(2) turn followed multitouch of entry (add this to your Builder):

flash.ui.Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

(3) allow the capture of the event:

ship.addEventListener (TouchEvent.TOUCH_BEGIN, press_start);

stage.addEventListener (TouchEvent.TOUCH_MOVE, press_moved);
stage.addEventListener (TouchEvent.TOUCH_END, press_end);

(4) for each of the press_start, press_moved and press_end fuctions, add the following code to ensure that the use of multiple fingers is not screw up:

If (event.isPrimaryTouchPoint == false) Then return

Works like a charm!

  • How to stop a brake if the mouse pointer leaves the scene?

    Hi all

    I have a big dot on the screen which can be moved around the mouse. I simply put an invisible button in the article with:

    {We (Press)}

    this.startDrag ();

    }

    {We (Release)}

    this.stopDrag ();

    }

    But if I move the mouse outside the stage area by dragging the element and release the mouse button release is not detected and the trail remains on and I have to get the pointer to the scene and click and hold the button to stop the operation slide.

    Is it possible to disable a brake when the mouse is released outside the bounds of the scene, perhaps using a different method that does not rely on a button?

    Any help is appreciated!

    Just change your bit of code and you will get it. I pasted the source code update have look on this

    {We (Press)}

    this.startDrag ();

    }

    {On(Release,releaseOutside)}

    this.stopDrag ();

  • Does not detect the hdmi cable more (very specific scenario)

    Well then...

    Got a monitor 15-HD to hdmi cable and a mac laptop (13 in the retina).

    So when I got all that I put it all together and it worked. I left because there a little bit, everything is plugged in and did not return for some time, so my mac fell asleep at the time wherever I went. Disconnected everything to relax on the couch. I went back and all plugged together again except that now the mac does not detect the cable. Tried a bunch of things with it. Restart, unplug the unit, detection manually, etc...

    Since the monitor is used and recently purchased cable, I thought time to them to test first. Got a laptop PC and plugged into the cable. The monitor and cable worked.

    Tried to connect my mac to the TV with my ps4′s hdmi since I did that a lot before. Also works.

    The problem is literally the combination between the cable and the mac. Which is a problem since I got the reason was to serve as my mac.

    During my research, I saw that specifically leaving the connected hdmi where sleeps your laptop can spoil it supposed to be... I saw it one time so idk if it's true, but it happened to me... and no, it wasn't really a solution when I came across that. Tried Googling this specific problem, but did not meet anything since my problem seems so specific.

    Fast forward to the next day and tried again now that both had little respite between them. Plugged into the HDMI and my laptop starts fading and return to a black screen. The screen would go black usually and so the laptop screen and the monitor would appear once again. sauf_que this time that there not, he just kept it and the monitor has not changed (Yes) it's). Not wanting to let him do that too long I unplugged and tried a different port with an adapter, I have also, since I did 3 holes I could use this for might as well try them all again. But unfortunately, I don't have it trigger anything again. So I went through another round of troubleshooting to try to make it work, but here I am, trying to see if anyone else has had this problem and solved. I am back to wait another day I guess and just hope. If not idk what to do, except maybe to get another cable? I don't know if this would solve it well.

  • Detect the dial needle completed the change of value?

    Hi all

    Is it possible to detect when a needle dial finished changing value?

    I am creating a VI to request a change in working capital.

    I don't want the control unit with a request for every change in the needle of the dial of the swamp so I use mouse events.

    Can I use Dial: mouse upwards and the dial: left mouse to request a new change in working capital.

    However, you can always pass the needle when it is outside of the wheel, which does not lead to a step change request.

    I have attached my VI and any help would be appreciated gratefully.

    Phill

    How to detect the events and update the indicator.  I added "component: Mouse Up ' to update the indicator if the mouse leaves the button before falling from the needle.  This will add a nuisance update when the pane: the mouse upward is due to something other than a movement of the needle, but you can detect that in seeking a change in value on the dial.

  • 15 - n010TX: my HP Pavilion does not detect the integrated webcam

    Mr President.

    I have an integrated webcam which worked perfectly until recently. My laptop came with Windows 8 in 2013, and I upgraded to 8.1 Windows. However, now my computer is not able to detect the integrated webcam. I know that it's a software problem, because the material could not have been damaged.

    I tried to install software youCam"with the help of the HP Recovery Manager, and it was installed successfully. However, when I open YouCam, it does, "no available camera detected. Please check if the camera is connected and try again. Even Device Manager has no other choice "imaging devices". I guess that something disabled the webcam, and for some reason, no driver is able to turn it back on

    I need to get this camera working. My product name/number is 15-n010TX. Please let me know what I can do...

  • Detect the number of boxes checked

    Let's say I want to detect the number of checkboxes selected in a container, how would you do that exactly? Is there a way to get the properties of the child elements?

    This has been me all day stumping. Thank you.

    There are many ways to detect the active elements. Why don't you examine them in Javascript? If you know how much check you have in the container boxes, it's the best way I think. You must add each box an id and when of the event triggers (e.g. Press button, navigate forward), you check each property check checkboxes in Javascript, as:

    onClicked {
     var checkedNum = 0;
     if (checkBox1.checked) checkedNum++;
     if (checkBox2.checked) checkedNum++;
     if (checkBox3.checked) checkedNum++;
     etc....
    }
    

    But if you dynamically create checkboxes, you can get the full list of the QML next to C++ object.

    In the projectName.cpp file is a few lines generated automatically:

    AbstractPane *root = qml->createRootObject();
    // set created root object as a scene
    app->setScene(root);
    

    The root object contains all of the QML hierarchy. You can get it with this command:

    QObjectList children = root->children();
    

    Thus, the child is a list, and it contains elements of QObject. They may be iterating through a single for the cycle. Every QObject knows its class name, so with this code snippet, you can examine, whether or not the real QObject is a checkbox.

    for (int i = 0; i < children.count(); i++)
    {
      if (children.at(i)->metaObject()->className() == "CheckBox")
      {
        //do something
      }
    }
    

    I hope it helps.

    see you soon,

    You may need to update your display and video driver

    This is my generic how updates of appropriate driver:

    This utility, it is easy see which versions are loaded: run DriverView - define the VIEW
    for the drivers Microsoft hide - updated those without drain in their names. (Also updated
    the BIOS and chipset drivers.)

    -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    Description, version, product name, company that created the driver and more.
    http://www.NirSoft.NET/utils/DriverView.html

    For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
    Control Panel - Device Manager - Display Adapter - note the brand and complete model of your
    video card - double - tab of the driver - write version information. Now click on UPdate Driver (this
    cannot do anything as MS is far behind the certification of drivers) - then do a right click - Uninstall - REBOOT
    This will refresh the driver stack.

    Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party with their
    own the software and drivers and all other main drivers that you have.

    Now go to the site of the manufacturer of system (Dell, HP, Toshiba as examples) (restoration) and then of the manufacturer of the device
    (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for the BIOS, Chipset and software)
    updates on the site of the manufacturer of the system here.)

    Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after each installation.

    Always check in the Device Manager - tab drivers version you install actually shows up. This
    because some restore drivers before the most recent is installed (particularly that audio drivers) so install a
    pilot - reboot - check that it is installed and repeat if necessary.

    Repeat to the manufacturers - BTW on device at the DO NOT RUN THEIR SCANNER - manually check by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  • Detect the collision does not

    I created a class called code battery and he added inside a function named "Clone". Battery is derived from a base class of Components.as with a file name. Here's where I'm adding battery inside a function named "clone":

    var ComponentRef: Class = getDefinitionByName ("Battery") in class;

    var object: instance = new ComponentRef();

    addChild (DisplayObject instance (instance));

    instance.x = 500;

    instance.y = 300;

    instance.compName = "battery."

    instance. AMPERAGE = 20;

    instance.partNumber = "BA12345";

    I have also a clip with an instance name of "negativeProbe" that I add an event listener for:

    negativeProbe.addEventListener (Event.ENTER_FRAME, detectedColl);

    This brings me to the detectedColl function when I'm doing the collision detection:

    battery: battery of var = new Battery();

    If (battery.hitTestObject (negativeProbe)) {}

    trace ("collision!");

    Trace never recorded a success. I don't get an error, but no shot is ever recorded. What I'm doing wrong here?

    Here, you have added the "instance" object to the scene

    addChild (DisplayObject instance (instance));

    but this object not added!

    battery: battery of var = new Battery();

    If you have an object with the name 'battery', but it is not on the stage and he will never hit another object unless you add it.

  • How can we detect the action of "clicking outside of the dialog box"?

    When we have a modal dialog box, click outside of the dialog, its parent window, for example, how this action event can be detected? I want to implement certain actions in response to this event. Thank you!

    Here are some ideas for further research:

    You can first in the stage variable parent in the dialog box and then attach to events 'touch' here:

    scene.setOnMouseClicked (myDialog.mouseHandler,

    scene.setOnTouchReleased (myDialgog.touchHandler

    But it can work only if the dialog box is directly on top of the scene of the mother.

    If the dialog box is outside parent in any part you will probably need to work with the operating system.

    In windows, you will need to call some functions search for win32 if ' use java call win32 functions.

    Or, you can write a windows program that listens to the operating system event queue, then tcp to your dialog box.

    Many search results obtained: windows - how the message queue works in Win32 - stack overflow

    But then if your mac or Linux,...

  • Help! Object enter the scene, stop for a second, then go. How?

    Hello world

    I am a beginner in AE and I'm trying to animate a bus I made using illustrator. This bus is suppose to enter the scene, stop in the middle of it, than to start over and leave, simulating a bus stop.

    Now, I realized to get into the scene and get to the point where I want, but how can I do stay there for a second or two and then start again, because if I add a keyframe after a second it does not block and it continue. I'll add a screenshot of my calendar to show you!

    Schermata 2014-10-08 alle 12.31.05.png

    The first key frame is where the departure of the bus, and the second is where he suppose to stop and where my red line is I want to do it over again, so the time between the second keyframe and the red line is where I want the bus stop!

    Thank you

  • stop the music during the scene change

    I make a game with AS3. I want to put different music in each context.

    So far I managed to start the music when the player enters a scene. But if it turns off, the music is still playing... (I want the music to stop when the players leave a scene).

    I do not understand why the music is still playing... Here is my code:

    My mp3 file is named "exterieur.mp3".

    If you can think of anything, it would be a great help.

    Thank you!

    If you want the music to stop, you tell him to stop.  The Sound class doesn't have a stop method, but done SoundChannel class.  You create a SoundChannel instance and assign to the transformation of Sound.play.  Then you can use it to stop the sound.

    var sc:SoundChannel;

    SC = mySound.play ();

    TCI Stop(); to stop the sound
