Actionscript :: Targeting Sprites From A Method In The Document Class - Null Object Reference?
Feb 9, 2011
I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.
Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.
I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.
"Cannot access a property or method of a null object reference."I'm trying to get a button to go to a frame in my movie and stop. The code I am using is
Code:
btn1_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler5); function mouseDownHandler5(event:MouseEvent):void { gotoAndStop(19); }
I have a slight problem. 3 scenes one named home , gallery and profile . 3 buttons each named after the scene. Whenever i test it and click a button to go to another scene i get this TypeError: Error #1009: Cannot access a property or method of a null object reference.

I have been trying to design a maze game for college project but I seem to be stuck and hoping someone can help me out. Get error:1009: Cannot access a property or method of a null object reference.at code::Game1$iinit()New to flash so not sure what this means. [code]
well i have a problem with my analog clock. i have it in my homepage and now it's working fine, but when i test my movie and click in my portfolio, for example, my output windows gives me this error: TypeError: Error #1009: Cannot access a property or method of a null object reference. at index_fla::MainTimeline/clock() i don't understand because even when i change from page to page (or frames) the clock is still working and everything is ok... but the message keeps appearing till i close my test movie window... and i've noticed that when i go online, there are some files missing that weren't till i had the clock on my homepage.[code]
I am just trying to watch television episodes on my laptop. this error has been popping up for the last couple weeks for no apparent reason. At first, it also said the Flash Player didn't work with 64 bit whatever with IE8. The error said a patch was not yet made and to use IE 32 bit. I did this and am still getting the error. I have uninstalled flash player and reinstallaed it to no avail. This error led to further problems on my laptop resulting in a total crash. Fortunately, I was able to back up all my files before they disappeared. I restored the computer to a time before I started watching television programs on XFinity.com (about a couple months ago) and it seemed corrected for a while and then the error started again. I am given the option to continue or dismiss. either button allows me to continue watching the program, but then repeatedly appears even when I quit XFinity and watch the shows directly from the network websites.
I'm trying to create a simple user name and passwor screen which will link to a menu and in the menu will have a choice of three games to play.frame 1 is the logon screen. Frame 2 the menu. Frames 3,4 and 5 the games.I managed to create the logon screen, the menu and the first game but the error below appears when clicking on the button to go to the first game in frame 3
Cannot access a property or method of a null object reference. at logon_Scene1_fla::MainTimeline/init() at logon_Scene1_fla::MainTimeline/frame3()
I have a mutiple choice quiz which is spread across a number of frames, the same script is used for each frame only using different named variables.The code works fine on the first frame but I get the Runtime error 1009 on the 2nd, 3rd etc frame.My guess is it's to do with the way i've declared the next_btn, but im not sure.[code]
AS3 and object oriented script. My issue involves instantiating movieClips and referencing them correctly to avoid:Error #1009: Cannot access a property or method of a null object reference.I've spent hours researching this and know I am referencing an object that is not there but I don't understand how to instantiate the movieClip (I think I need to generate a class for the main movieClip?) I am such a noob and really apologize for the lame question. my file is hereThe file works but I know I'm doing it wrong and really would love to know the right way!Here's the full error:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at problem_file_fla::avalanch_holder_6/frame200()[problem_file_fla.avalanch_holder_6::frame200:4]
Im getting a 'TypeError: Error #1009: Cannot access a property or method of a null object reference' when I try to gotoAndPlay(15) in my .fla file. It can start playing frame 15 fine if there is no actionscript on it ie just an image but as soon as I add actionscript code it gives me the error. I have been trying for hours to try and solve it so if anyone coud help it would be much appreciated!I have included the.fla file and stripped most of the graphics out so it's under 300kb limit.
I try to do preloder in Flex for my project written in Flash. I make this with the help of this site link text My Flash project have next source in main class called Game
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDown); stage.addEventListener(KeyboardEvent.KEY_UP, keyUp); private function keyDown(event:KeyboardEvent) {
[Code]....
Flex application work but Flash application does not react to button presses
how I can make preloader and work buttons together

Because of this I am fighting with a number of packages that control a game I am trying to build. What I'm struggling with now is a map class being added to a strategyGame class.
The strategyGame.as listens for the spacebar to be pressed and held. Then calls spaceListener() in the map() which allows the the user to click and drag the map to move it on the stage.
But when I test the movie I get an error:
Code: TypeError: Error #1009: Cannot access a property or method of a null object reference. at map()

I'm creating a simple point and click flash game based on this tutorial [url]... and have run into a snag that has stopped me from progressing
I simply want a key to be able to open a door and allow the player to continue if they have collected it. The only difference between the tutorial project and my project is that the key and the door are on different keyframes. I have added a boolean value for the key on a seperate script layer - that seems to be working fine, however, when I try to add the script for the key I get this error?
I got a script online for an easy scroll bar.at first i had the code embeded in flash but i noticed it would not work well since im trying to use it on different frames, so im trying to code it as an external class and i manage to take alot of errors out, but now im stuck with the 1009 error.
i read a nice little tutorial that explains how to use ADDED_TO_STAGE listener and i thought it would fix my problem, but im still stuck with the error[code]...
I'm a complete newbie and really not that good at ActionScript. I'm making an interactive toy for a Uni assignment that needs to be handed in next week.
I have a few problems but the one I really need to sort out is: I'm getting this error:
"Cannot access a property or method of a null object reference."
I searched all day yesterday (whole day, haha and nothing lol) and I know that it means that an object is being loaded that hasn't been created yet. But, I really am not very good at this since we just started this module.
I also for some reason can not remove a child. On frame 6 I have to remove children from two other separate frames. (This code can be found at the bottom of frame 6) The order in which I remove them have an affect. The one that comes first is removed but then the other isn't.
I have this preloader code on frame 1 in my MAIN swf file with the content on frame 2
Actionscript Code:
stop(); //Import the required assetsimport flash.display.*;//Stop the playhead while loading occursthis.stop();//Create a listener to call the loading function as the movie loadsthis.loaderInfo.addEventListener (ProgressEvent.PROGRESS, PL_LOADING);/*This is the main function,
[code]....
Also an external swf file is loaded using the same code on frame 1 in its main timeline this works when I test local but it outputs an error....
at welcome_fla::MainTimeline/PL_LOADING() TypeError: Error #1009: Cannot access a property or method of a null object reference. at welcome_fla::MainTimeline/PL_LOADING()
On line this prevents it from working at all.Basically I need each external content to have its own preloader for its content.If you go to my site you will see it works on the intital load but when you hit the home button it fails [URL]
Im using CS5 i am a novice and i am doing this for my A level project and i cannot seem to get my button code to work properly. I've set it pinpoint debugging stuff that people have been going on about.
