Alright so I am using the stencyl engine to make a flash game, and I wanted to upload an Swf file. The problem is I keep getting an error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at _247gamesonline_fla::bn0_Symbol1_2/frame1()
Now I went to that part of the fla file that had the error, and tried to see what was wrong, but could not figure it out. Here is the code:
stop();
var doMain:String = this.stage.loaderInfo.url;
var doMainArray:Array = doMain.split("/");
var domainname = doMainArray[2];
var gamename = "nameofgame";
var linktodjp = "http://www.247gamesonline.com/? p=cat&order=2&tag=puzzle&utm_medium=partnergame&utm_campaign=" + gamename + "&utm_source=" + domainname + "&utm_content=partnergame";
var linktodjpfb = "http://www.facebook.com/connect/uiserver.php?app_id=201345053230176&next=http://www.3j.com/processfacebook.php%3Futm_source%3D" + domainname + "%26fgamet%3D76&display=page&cancel_url=http%3A%2F%2Fwww.3j.com%3F3Futm_source%3D" + domainname + "&locale=en_US&return_session=1&session_version=3&fbconnect=1&canvas=0&legacy_return=1&method=permissions.request&perms=publish_stream,offline_access,email,user_birthday,user_interests,read_friendlists";
buttonplay.addEventListener(MouseEvent.CLICK, playlogonow);
logo.addEventListener(MouseEvent.CLICK, gotowebsite);
logo.buttonMode = true;
stop();
function playlogonow(e:Event) {
logo.play();
gotoAndStop(2);
return;
}
function gotowebsite(e:Event) {
navigateToURL(new URLRequest(linktodjp));
return;
}
Also in another part of the code it simply says
on (release) {
_root.play();
}
Help anyone?
Difficult to say by having that code only. Whatever, I would recommend to put many trace statements there to figure out what variable actually equals null and leads to that exception. Then act accordingly.

I'm working on an application and we are using Flash to add an interface. During the initialize the app loads in a config file with references to image paths. When I use the Loader and URLRequest classes to load those images the path is not working and it's causing issues. Based on everything I've researched my code should work. I have a trace that outputs "source/icons/default.png" which is the correct relative path for the external image and loading the image works, but I need to use a variable to set the image path. Setting the URLRequest with a variable, new URLRequest("source/icons/" + default.png);, causes it use a full file path that looks wrong and reports a 2035 error. Is there something that I'm doing wrong? I'm not sure what to do at this point. I've verified the file exists and I've verified the path of the file.
Trace Ouput:
source/icons/default.png
Error Output:
[CompanionStatus] Error occurred while loading bitmap
[CompanionStatus] 2035 : Error #2035: URL Not Found. URL: file:///C|/Users/devtrooper/Desktop/project/source/icons/default.png
It looks like flash is replacing the colon (:) near the drive letter with a pipe (|) and I'm not sure if that is the issue.
Here is my method for loading images:
private function getBitmapData(nameString:String, imagePath:String):void{
try{
var bitmapDataFunction:Function = addBitmapDataToDictionary(nameString);
var path:String = ICON_FOLDER_PATH + imagePath;
var loader:Loader = new Loader();
var urlRequest:URLRequest = new URLRequest("source/icons/" + imagePath);
trace("URLRequest.url " + urlRequest.url);
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, bitmapDataFunction, false, 0, true);
loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, handleBitmapDataError, false, 0, true);
loader.load(urlRequest);
} catch (e:Error) {
log("Error occured while trying to load image data");
log(e.name + " : " + e.message);
}
}
you can use File method instead of urlRequest method like this:
var urlPath:String="";
var picFile:File = File.desktopDirectory.resolvePath("source/icons/default.png");//you can use applicationDirectory,applicationStorageDirectory,userDirectory,doumenntDirectory and ...
if (picFile.exists == true) {
urlPath = picFile.url;
}
I've been seeing some tools for a browsergame that injects code to a swf file in order to automate some parts of the game.
I've been reading about swf flash format and I'm still don't knowing how that's possible, maybe the program runs the swf file with a custom flash player?
If you could guide me in this I would be very appreciated, this is very interesting.
Just a try:
var actionString:String = "methodAddOne";
var paramString:String = "1";
function methodAddOne(num:String):void{
trace(Number(num)+1);
}
this[actionString](paramString); //trace: 2
For a queue of params:
var actionString2:String="methodAdd";
var paramString2:String="1,2,3,-6";
function methodAdd(nums:String):void{
var params:Array= nums.split(",");
var out=0;
for each(var num:Number in params){
out += num;
}
trace(out);
}
this[actionString2](paramString2);// returns 0
All calculations, core-Methods,... you have to parse. Very complicated...
E.g. try to parse and calculate "1+2+3-6". Its possible of course, but hard to do with other Stuff and math-grammar.
So, the easier way is to provide a String-based Api with all methods, the
user can predefined use with params.
like this:
var stackString:String = "methodAddOne(100); methodAdd(1,2,3);";
function parseFunctionsString(str:String):void
{
//better use regExp at all the following
var f:String = str.substring(0,str.indexOf("("));
var p:String = str.substring(str.indexOf("(") + 1,str.indexOf(")"));
// clean spaces // also better regExp to validate some other user mistakes - just for this test in this way
f = f.replace(" ","");
p = p.replace(" ","");
//trace("** "+f+" ("+p+")");
if (this[f])
{
this[f](p);
}
else
{
trace("unknown function: "+f);
}
str = str.substr(str.indexOf(";") + 1,str.length - str.indexOf(";") + 1);
if (str.length > 2)
{
parseFunctionsString(str);
}
}
parseFunctionsString(stackString);
// trace:
// 101
// 6
As an idea... Greetings André
In Unityscript I'm able to directly access audio data. In the scene, I have a gameobject with a sound file and a script attached to it.
var mySound : AudioClip;
mySound = audio.clip;
var mySoundChannels = mySound.channels;
However, I'm having problems trying to access audio data via a function:
#pragma strict
var mySound : AudioClip;
function Start()
{
mySound = audio.clip;
GetAudio(mySound);
}
function GetAudio(au)
{
print ("Audio: " + (mySound === au)); // true
//var mySoundChannels = mySound.channels; // works
var mySoundChannels = au.channels; // fails
var stereoOrNot = (mySound.channels == 2 ? "stereo" : " mono"); //works
print(stereoOrNot);
}
I thought I could access au.channels, but I'm not sure where I'm going wrong I (apart from wanting to access audio indirectly)
Since you are using a dynamic variable there, I'm not sure if the var mySoundChannels will be typed to an AudioClip or an int. If it is an AudioClip then it will fail because channels are read only. Try it with int mySoundChannels = au.channels;
I have a variable
var qstAccessCode:String = "default";
and a loader with URLRequest
var qst:XML;
var qstLoader:URLLoader = new URLLoader();
qstLoader.load(new URLRequest("http://dl.dropbox.com/u/44181313/Qaaps/Audio/" + qstAccessCode + ".qst"));
qstLoader.addEventListener(Event.COMPLETE, processQST);
function processQST(e:Event):void {
qst = new XML(e.target.data);
trace("QST loading");
}
I would like to use the value of qstAccessCode to complete the URL (so I can change the URL based on user input - if no input then use "default") but I get an error:
"1120: Access of undefined property qstAccessCode"
Is this to do with scoping? How can I complete the URL? Thanks in advance.
Edit: I haven't been able to get clear on this, so I'm also going to look at generating the complete URL from the user-input function and see if I get the URLRequest to pick it up as a variable. If there are any further comments on the original idea I will be very grateful to read them. Cheers.
Edit: #Moorthy I have qstAccessCode defined like this:
var qatAccessCode:String = "default";
var stageText:StageText = new StageText();
stageText.returnKeyLabel = ReturnKeyLabel.GO;
stageText.stage = this.stage;
stageText.viewPort = new Rectangle(225, 765, 200, 35 );
stageText.addEventListener(Event.CHANGE, onChange);
function onChange(e:Event):void
{
qatAccessCode = stageText.text;
trace(qatAccessCode);
}
It traces keyboard entry when I test movie (Air 3.2 for Android).
qstAccessCode should be defined in the same scope as the URLRequest.
You must defined property qstAccessCode like:
var qstAccessCode:string;
qstAccessCode's value is your url address.
In the following example (yes, I am coding on my timeline while I try to work this out - I know, I know) I am loading an SWF in an HTML page and then directing the SWF to get the query parameters from the current URL. The query parameter will contain the source for the video to play.
This seems straight forward to me but I cannot get myURL = urlVars.videoloc; to work. More specifically, urlVars.videoloc seems to be undefined rather than holding the query parameter from the URL. All other variables are correct; both wholeURL and urlVars are defined.
//Initialize Global Event Listener
player.addEventListener(Event.ADDED_TO_STAGE, getPlay, false, 0, true);
//Function to play the video
function getPlay(e:Event):void {
var wholeURL:String = ExternalInterface.call("window.location.search.toString");
var urlVars:URLVariables = new URLVariables(wholeURL);
var myURL:String = urlVars.videoloc; //<--- Trouble, returning 'undefined'
errorBox.text = "videoloc="+urlVars.videoloc+"\nwholeURL="+wholeURL+"\nurlVars="+urlVars+"\nmyURL="+myURL; //<--- The reason I know it is returning 'undefined'
if (myURL) {
player.load(myURL);
player.play();
}
}
Ideally you should use a debugger to inspect the makeup of your URLVariables object.
If you're unable to do things the easy way, you could do this to trace its contents:
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
As you can see, you can step through every parameter inside urlVars using a for in loop.
I'm guessing videoLoc is your first parameter? Look at the results of this test of mine:
var address:String = "http://www.google.ca/search?q=test&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a";
var urlVars:URLVariables = new URLVariables(address);
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
The output of this is:
aq=t
rls=org.mozilla:en-GB:official
client=firefox-a
http://www.google.ca/search?q=test
ie=utf-8
oe=utf-8
See what happened to the q parameter? To fix this, use only the text past the ?
var address:String = "http://www.google.ca/search?q=test&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-GB:official&client=firefox-a";
var urlVars:URLVariables
= new URLVariables(address.substr(address.indexOf('?')+1));
for (var parameter:String in urlVars) {
trace(parameter + "=" + urlVars[parameter]);
}
