Problem error null object reference

Hello, I'm having a problem with a class (_gameModel), to instantiate in another class (_gameController), and when I try to reference the _gameModel class in the class of _gameController, I get an error of object reference anywhere, even if I know that the class is instantiated at the top of the page of class _gameController.  I thought that if it was instantiated in the class, then I don't have this problem but I am. Someone knows what's the problem? Thank you

I don't see anything being instantiated compared to what you said, so I can't say if it of a problem or not.

You showed only a part of the error message or is there more information in it?  Display the full error message if it is not all that.

Based on this function involving 'EnterFrame' in the name, my suspiscions down wondering if you spread this error once the object has been deleted on a previous passage through the function.  How to watch the traces of this first line of the function?  Does come with a null value when the error occurs, but looks OK before that?

    Found the solution (via the devgirl.org blog comments).  It turns out that this is a known problem in Flash Builder 4.6 with the TextInput skin.  Quick and simple solution is to add

    skinClass = "spark.skins.mobile.TextInputSkin"

    for the TextInput tag and everything works again (I heard him talk about a problem with StageText and as you can see, which appears in the stack trace I became).

    Also became strangeness when exporting for Android (entries endangered and appear outside the textinput).  I hope this will fix this problem too.

    When Flash tells you that there is a null object reference, this means that an object that you are referring to a function is not available at this time here in the film. It is usually a problem with the object being not not in a particular setting. Make sure that the object, the key is actually in the frame where the function reference.

  • Help, please! TypeError: Error #1009: cannot access a property or method of a null object reference.  Help, please!

    Can anyone help! Here's the code from to escape the game of the room that I am creating.  Basically the user will be drag and drop items to reveal the user will collect hidden items.  I got the elements of drag-and - drop but I have a problem with the service that I write to recognize what are the elements and how much has been collected.  I just get the error

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    at TheMathsRooms_fla::MainTimeline/ObjectFound()

    When I click on one of the elements, the user must be able to collect.  I checked the chronology and pint, the script is used all THE elements are on the scene.  Any ideas?

    function objectFound

    function ObjectFound(event:MouseEvent):void {}

    var room1_inventoryName:String = "room1_inventory" + event.target.name;

    var room1_inventoryItem:DisplayObject = getChildByName (room1_inventoryName);

    Event.Target.alpha is room1_inventoryItem.alpha = 100;.

    founditems ++;

    Event.Target.alpha = 0

    }

    Here I put the items in stock to be invisible until they are

    room1_inventoryone_mc.Alpha = 0

    room1_inventorytwo_mc.Alpha = 0

    room1_inventorythree_mc.Alpha = 0

    room1_inventoryfour_mc.Alpha = 0

    room1_inventoryfive_mc.Alpha = 0

    room1_inventorysix_mc.Alpha = 0

    A variable is created to count the number of items the player has found.  At the beginning of the game, it is set to 0

    var founditems:Number = 0;

    Here, I'm telling Flash to keep track of what the user has found by listening to what were clicked on and then by running the objectFound function.

    room1_hiddenone_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    room1_hiddentwo_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    room1_hiddenthree_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    room1_hiddenfour_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    room1_hiddenfive_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    room1_hiddensix_mc.addEventListener (MouseEvent.MOUSE_DOWN, ObjectFound);

    Here's the function to allow the items to drag and drop

    function StartDragging (e:MouseEvent) {}

    e.currentTarget.startDrag ();

    }

    function StopDragging (e:MouseEvent) {}

    e.currentTarget.stopDrag ();

    }

    This shows that items can now be dragged and lowered some will reveal hidden items

    Bluechair.buttonMode = true;

    Bluechair.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Bluechair.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Pencilcase.buttonMode = true;

    Pencilcase.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Pencilcase.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Painting.buttonMode = true;

    Painting.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Painting.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Rubbish.buttonMode = true;

    Rubbish.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Rubbish.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Painting2.buttonMode = true;

    Painting2.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Painting2.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Trunk.buttonMode = true;

    Trunk.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Trunk.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Pillow.buttonMode = true;

    Pillow.addEventListener (MouseEvent.MOUSE_DOWN, StartDragging);

    Pillow.addEventListener (MouseEvent.MOUSE_UP, StopDragging);

    Click file > publishing settings > swf and check the box "enable debugging".  test.

    the number of problematic line will be in the error message that allows you to quickly identify the problematic reference which is probably room1_inventoryItem.  use the function trace to confirm:

    function ObjectFound(event:MouseEvent):void {}

    var room1_inventoryName:String = "room1_inventory" + event.target.name;

    trace (room1_inventoryName);

    This isn't a problem of Flash... it's a mistake to designer.

    1009 error indicates that one of the objects targeted by your code are out of reach.  This may mean that the object...

    -is declared but not instantiated

    n ' is not have an instance name (or the name of the instance is misspelled)

    -is animated in place, but is not assigned the name of the instances of each keyframe for her

    -is one of the two or more consecutive keyframes of the same objects without a name assigned in the image previous (s).

    It could also be other less obvious reasons.

    If you go to your section to publish the Flash settings and select permit debugging option, your error message should have a suite of line number the number of the frame that will help you to isolate the object that is involved.

  • TypeError: Error #1009: cannot access a property or method of a null object reference.      at Mannstyrt

    You have a problem with a 'game' that I'm doing (just a little, to test its functioning). The idea is that you start as a man in a maze and then use the arrows to direct him. Recently, we started with interactivity with flash professional CS5.5.

    The error I get when testing is:

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    at MannstyrtavpiltasteneTEST_fla::maintimeline/collisionmal() [MannstyrtavpiltasteneTEST_fla. MainTimeline::frame1:260]

    But this project is copied to another where we used buttons to direct an object, and I copied some code out of a youtube video that so I'm naïve now...

    I had three images in this game:

    The first is the game, where you start in the maze and make your way to the goal.

    The second is the plot of 'losing', that appear when the man is colliding with the walls.

    The third is when you win the game, which is mostly just a congratulation.

    When I go through two and three, I get the error. I guess I need to run the buttoncodes sort of way, so that the flash searching in fram 2 or 3. The game works fine, but the errors is not good, even if the game works.

    And the second problem is that every time that I lose or win and return to the framework one speed is multiplied by 2, it moves 4 PX instead of 2, etc.

    Any ideas?

    The error indicates that line 260 of frame 1 is where an object is covered by the code, but it does not exist as far as the compiler sees.  You can use the trace() function to determine the object that could be, but if there is only a single object on the line, this object will be the one.

    For your second problem, you must change the value of the speed somehow, so you will need to look at the code from frame 1 closely to see why this might be.  Still, you can probably use the trace() function to see when the value changes.

  • TypeError: Error #1009: cannot access a property or method of a null object reference.      to tail/Chec

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    to Tail / CheckCollision ([Tail::frame1:5])

    I have 2 movieclips, head and tail placed on stage (frame 1 and exported for ACE), head is the name of the instance of head, the tail has instances tail_1, tail_2, tail_3, tail_4 , I'm trying to detect collisions between these two. When head hits any instance of the queue class I want to delete tail_3 and tail_4 how this can be done?

    Code on frame 1 of tail MC

    function CheckCollision(evt:Event):void

    {

    If (Math.abs (MovieClip (root).head.x - x) < 20 & & Math.abs (MovieClip (root).head.y - y) < 20) / / 20 is the size of each and registration is at the centre

         {

    MovieClip (root) .collisionDetected = 1;

         }

    }

    addEventListener (Event.ENTER_FRAME, CheckCollision);

    Code on the MainTimeLine

    for (var m:uint = 3; m < = 4; m ++)

         {

    removeChild (getChildByName ("tail_" + m));

    tail_3 and tail_4 are dynamically added class tail by another function (which is not relevant here), tail_1 and tail_2 are on //stage

         }

    I get this message but SWF file works fine, there is no error either, and BTW if I don't know this message there will be a problem with performance, this message very much continue to pour into the output window (I guess that's normal since I ENTER_FRAME event)

    If you add these bodies without a name in one table, then you can loop through the array and use something like...

    for (var i: uint = 0; i

    {if (mcA.hitTestObject (mcBArray [i]))}

    No matter what

    }

    }

    You can probably also do the same at the breast of each mcB, just using the reverse, without looping...

    {if (this.hitTestObject (MovieClip (root) .mcA))}

    No matter what

    }

    You just need to be sure that you are targeting mcA (or BCP) correctly, which you can determine by drawing the target.

  • Error 1009: Cannot access a property/method of a null object reference

    OK, so I've spent the last few weeks trying to figure this on my own, looking at the other tutorials and nothing has helped my situation. I am beyond frustrated with this project and I just want to find an answer quickly. I have some experience with Flash to school, but I can't understand this because it doesn't make sense to me.

    I have two main parts of my file. I have a photo gallery and I have a video. The home page allows the user to take them to a number of areas where they can see a gallery of photos or video from a certain city. Photo gallery works fine as do videos. Well, now, user can get the gallery photo to video, but when I try to set up exactly the same thing to bring video to the images it gives me an error of output message:

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    The code that works very well is as follows:

                            nextFrame();

                }

    btn_next_brownton.addEventListener (MouseEvent.CLICK, showNextPicBrownton);

                            prevFrame();

    }

    function showBrowntonVideo (e: Event): void {}

                            gotoAndStop (7);

    }

    btn_brownton_videofrompics.addEventListener (MouseEvent.CLICK, showBrowntonVideo);

    But where everything goes wrong here:

    function showBrowntonPhotos (e: Event): void {}

                            gotoAndStop (1);

    }

    btn_photos_brownton.addEventListener (MouseEvent.CLICK, showBrowntonPhotos);

    All this code is not on the main timeline, but in a movie clip called mc_brownton where I have the pictures and video all on the same timeline.

    If someone could help, I would be eternally grateful. I'll throw my computer against the wall.

    Click file/publish settings/flash and check "permit debugging".  Repeat the test.  the line number with the null object will be in the error message.  to highlight this line of code if you cannot solve the problem with this info.

  • DONKEY - Vibration error: cannot access a property or method of a null object reference.

    Hi all

    I am trying to use the Vibration DONKEY but get the following error:

    IsSupported() vibration

    TypeError: Error #1009: cannot access a property or method of a null object reference.

    Manufacturer of vibration: create a context of extension

    at com.adobe.nativeExtensions::Vibration$/initExtension() [/ users/meetshah/Documents/Adobe Flash Builder 4.5/VibrationActionScriptLibrary/src/com/adobe/nativeExtensions/Vibration.as:58]

    to com.adobe.nativeExtensions::Vibration$/get isSupported() [/ users/meetshah/Documents/Adobe Flash Builder 4.5/VibrationActionScriptLibrary/src/com/adobe/nativeExtensions/Vibration.as:43]

    views::Tour/onMarkerClick() [/ < path to project here > / src/views/Tour.mxml:204]

    The code I am using is directly from the example:

    var vibe: Vibration;

    if (Vibration.isSupported)

    {

    Vibe = new Vibration();

    Vibe.VIBRATE (2000);

    }

    Not really sure why this could happen. If anyone has any suggestions, it would be much appreciated!

    Thank you

    I thought about it. It seems that the native extension has not been properly packed (check the parameters of the project, Flex Build Path and Extension Native for the iOS and Android).
