ActionScript 3.0 :: Null Object Error When Adding Sounds
Jun 16, 2011
I'm creating a flash game with AS3 but I'm having some issues with sounds. Usually, when there is not much action around, sounds play just fine and all. But when it starts getting ugly with explosions everywhere and stuff, I start getting this every now and then[code]...
the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
I added a flv into my Scene 1 then i added a new Scene.I just wanted to after finishing the .flv flash go to next scene.but when i added a new scene,and I test my movie,the .flv didnt show and i recieved these errors
stop(); button3.addEventListener(MouseEvent.CLICK, playClick3); function playClick3(Event:MouseEvent):void { gotoAndStop(422); }
On frame 422 there is no code at the moment. I keep getting the error TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am trying to use the scroll pane component and I am having a few teething troubles. I have a scroll pane as a child object of a movie clip which is essentially a 'page', if I display this page it works fine and the scroll pane does too. If I then remove this page from the display list, go to another page and come back by readding it to the display list, I get the following error, even though nothing else has changed:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at fl.containers::ScrollPane/fl.containers:ScrollPane::endDrag()
The scroll pane is still visible and works correctly, but ideally I'd like to stop this error.
I'm having trouble with my code. I keep getting this error TypeError: Error #1009: Cannot access a property or method of a null object reference. at Test_fla::MainTimeline/frame1() I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true); for(var i:uint=0; i < numParticles; i++){ var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250); addChild(p); particles.push(p); } function onLoop(evt:Event):void { //for(var i:uint=0; i < numParticles; i++){ //particles[i].gravitate(1,1); //}}
So my problem here is, I'm working on my Adobe Air project, so I decided to code some buttons to be able to navigate. The problem here is that I get a error for trying to do so. Here is my code.
[Code]...
I do not see what is wrong actually, I tried this on a blank non-AIR file, and it worked well.
I'm animating some mc's at the beginning of the timeline with AS3 (mostly alpha fades), but then I have some tweened animations further down the timeline and a "naviagation bar" that's on all frames, so a user can click a button and jump to a part of the timeline to see some other animations.My problem is that if I don't wait to see the programmed animations at the beginning and just clicka button to see the other tweened animations, I get an error:
"Error #1009: Cannot access a property or method of a null object reference. at flash_fla::MainTimeline/tube_glow2_animate()" (tube_glow2_animate() being the name of a function)
Error #1009: Cannot access a property or method of a null object reference.
This is the error I cannot seem to understand. On the stage I have a movie clip, mcTree. It's keyframe is in frame 3143. There is no tween or anything. In frame 3144, I have the following actionscript:
mcTree.gotoAndStop(2);
I publish the movie and I get to frame 3144 then BAM TypeError: Error #1009: Cannot access a property or method of a null object reference.
at 2file_fla::MainTimeline/frame3144()
As you can tell, I'm more than 3000 frames into my animation here and have made it this far using this method, and it has worked.
I have problem with accessing object created by function imported from another package. I have 2 packages DragDrop and UserInterface. In UserInterface I create methods for buttons and later add them in DragDrop . I make it in two different ways: One(this one works):
I'm having a problem with this code for selecting a character for a game. The scrolling left and right codes work but when it comes to accepting the highlighted character.[code]All I want is for it to take the label of the current frame in the movie clip (which I defined already) and set it to a string, selectedChar.[code] p1c is an instance of the movieClip containing the characters.
I am trying to figure out the logic to remove a nullreference error that is popping up when an item is not dragged. Inthe code, I have a stopDrag setup for the stage. It works asexpected unless the user clicks the item but doesn't drag it. Itcauses the variable I have set to bring the name of the dropTargetto be a null which crashes the system. I have tried to declare thevariable with a default value but it still doesn't work.It is the targetStop code that it is crashing on. Is thereanyway to default a value so I can do an if / then statement todetermine if there is a value? I've tried: if (targetStop == null)but that doesn't seem to work.
i'm using a Rails backend with my App and getting a AsyncToken returned from it (a DB-Call to be specific)As far as i know the AsyncToken returns a result event when done loading all data from the request, this way its possible to make sure all data was loaded before executing some function which uses the data. i tried the following implementation to get the AsyncToken converted into an Array and plotting its objects as strings to the user:
var dataSrv:services.databaseservice.DatabaseService = new services.databaseservice.DatabaseService; dataSrv.addEventListener(ResultEvent.RESULT, dbListener); //DBOPERATION returns my AsyncToken var listData:AsyncToken = dataSrv.DBOPERATION;
I have function init, which runs on the creationComplete of the application. The init calls get_login_share_object funtion, in which objects are created, which are null.
Now my problem is that, I get a null object reference error on the Alert in "init()". How can I avoid that. Is it possible that I can have a check to see, if the objects are null the program should just skip reading the objects.
private function init():void { var stored_credentials:Object = get_login_share_object();
Here are my classes Main - creates preloader Preloader - createas Website Website - creates MainMenu
When a button in the main menu is clicked, it creates an object. And when another one is clicked, that object needs to be removed. The removing part got a little bit messy. package src { import com.greensock.TweenLite; import flash.display.MovieClip; import flash.events.MouseEvent; import flash.geom.Point; [Code] .....
i used some variable, which was not initialized properly. I got a runtime error related to Null Object Reference.It was a hell, to find out, which variable was it pointing to. Cannot it be more informative, if it says, on which particular variable ( or bunch of variables), did the compiler found the null object reference. Or atleast provide me the lineNumber/linenumbers where it find the null object.The informationlessness becomes more hell, when there is more than one line, in which such null objects are used. It's hard to determine, if the line removed currently was a correct attempt or wrong attempt towords debugging the code.
I have a page containing multiple image galleries and thumbnail scrollers pulling in from external XMLs. The first scene containing gallery 1 loads the thumb and full size image perfectly.We I navigate to the second scene containing a new instance of my scrollpanel and container movie clip for my full size image I this error: Error #1009: Cannot access a property or method of a null object reference.at index_fla::MainTimeline/index_fla::frame6()I am wondering if I have to remove an event listener from the previous frame. Everything on the stage has an instance name and I am calling all new variable son the second frame.
Im trying to finish a small project im working on and this is the only bit that i have difficulty with. I have an image which tracks the mouse and reveals a masked image below. When the user clicks on the screen it plays the rest of the movie.The error message is: TypeError: Error #1009: Cannot access a property or method of a null object reference. at newmovie_fla::MainTimeline/moveMask()
The code i have used is: stop() curtains.mask = light;light.cacheAsBitmap = true;curtains.cacheAsBitmap = true;
gallery1.swf is the default swf, when I click the btn for gallery 2 I get TypeError: Error #1009:Cannot access a property or method of a null object reference at allery1_fla::MainTimeline/startToMoveThumbs()
stop(); var Xpos:Number = 0;var Ypos:Number = 80;var swf:MovieClip;var loader:Loader = new Loader(); var defaultSWF:URLRequest = new URLRequest("swfs/gallery1.swf");
When I try to run this code with the main file being documentclass and the highest in the code heirarchy, it comes up with error 1009, but I cant see the problem. The playscreen class with the constructer function is there, in the same folder as the document class but document class is saying it is a null object reference. When I try to run the code with the main file being playscreen, there is no problem, it runs perfectly.
[Code]...
The playscreen class is too big to fit here and I dont want to trouble you with the details. But I can assure you it DOES exist and it is NOT null.
I've been fighting with this backwards and forwards and haven't identified the problem:I have three frames that I want the user to page through with forward/backward buttons. Three frames means 4 buttons, two forward buttons and two back buttons:[code]What it does is, the lets m press the first Next button and does go to the second frame, but it throws the following error and the other buttons don't work:[code]Why can't I shake this thing? Is there a better way altogether?
I have an error that is not negatively effecting anything, but I'd rather fix it if I can. I have to do with "MouseEvents" when I change from one scene to the next. As in the objects do not exist in the "new" scene so there is a "null object referenced" error. The objects are not referenced in the new scene. Its a "mouseOver" and so when the scene changes and the "MouseOut" happens it tries to exicute a funciton on an object that is no longer available. I was thinking of changing the functions to "if/Else" statements, as in: "if currentScene=X Mouse out, Else "NOTHING"
I got CS4 for Cristmas, and I am having trouble with my buttons. I have a button on each frame programmed to go to the next frame when I click it. All of the buttons worked fine until I put a movie clip on frame 12. Now when I click to get to frame 13, it goes back to frame 7. This is what it says in the output:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at WelcometomyChristmas_fla::MainTimeline/frame12() at flash.display::MovieClip/gotoAndStop()
This might be alittle complicated to explain but I'll try to do my best.I have a basic setup of 3x4 isometric boxes that you can drag and sort around on a grid. This works just fine. Each box is a instance of a custom class of mine called Kiste (which consists of several sub-objects).hile sorting I have to use a procedure like this to get the parent Kiste-object of the dropTarget as droptarget will always get me the "lowest" object possible instead of the topmost:
Code: function whileDrag(e:Event):void{ var dt:DisplayObject = dropper.dropTarget; // Dropper is a empty Sprite that is constantly
