But when I put a input text field ("T" icon in the as3 textfield palette) on the stage, and it refuses to compile, with the above error. I am not sure if this makes a difference, but I am writing my ActionScript in FlashDevelop, with compilation done in the Flash IDE. I also have both Strict Mode and Warnings Mode selected under Publish Settings -> Flash -> Script -> Settings... -> Errors. I have searched for solutions to this online, and the only suggestions out there seem to be to not insert the text field on the stag in Flash IDE, and instead dynamically create them in the document class. Is there a better solution?

The main object is, for now, declared as a static object in the Main class: public static var platformLevel:platformMap; public static var solidLevel:solidMap; I also made a map for platforms. And both have their specific objects, named platformLevel and solidLevel, which are both instantiated in the main room, and are both linked to their respective empty classes. platformMap and solidMap. I tried to turn on and off the 'Automatically Declare Stage Instances', but the issue with that http://stackoverflow.com/questions/23119605/error-1056-cannot-create-property-solidlevel-on-main is that I have at least one such instance whose x-y coordinates I need, and if I tick the option off in the settings, then I cannot refer to that object for position anymore (There's probably a smarter way to make x-y coordinates correspond between the code and the visualized stage?). I'm wondering if it is an issue that my variable is Static. Maybe the compiler sees a difference between Main.solidLevel and the solidLevel that I did in the stage? At any rate, I need the variables to be global, so there has got to be a way to work around that. The code that doesn't work looks like this: public function Main() { Main.platformLevel = new platformMap(); Main.platformLevel.x = 10; Main.platformLevel.y = 10; stage.addChild(Main.platformLevel); Main.solidLevel = new solidMap(); Main.solidLevel.x = 10; Main.solidLevel.y = 10; stage.addChild(Main.solidLevel); ... } It's probably interesting to note that the SECOND block is the issue, and not the first one, whereas they are near identical. actionscript-3 flash share|improve this question edited Apr 16 '14 at 21:14 asked Apr 16 '14 at 20:33 Tama Yoshi 649 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted You declared the reference as solidLevel, but you are trying to access to solidNiveau. Edit: The error occurs whenever you try to access a property which's inaccessible from where you want to access it. share|im

Hi everyone. I am new to As3 and I'm getting this error but not sure how to change it from a string. I can 'trace("myfilling: " + myfilling);' and this outputs the instance I want to change the X and Y position of fine but when I try to do myfilling.x = leftBaseX, it throws up cannot create property the error: ReferenceError: Error #1056: Cannot create property x on String. Could someone help please!? function generateRandomSandwhich() { while (numFillings < maxFillings) { var randNum:uint = randomNumber(0, (fillings.length - 1)); if(sandwhichFillings.indexOf(fillings[randNum]) == -1) { sandwhichFillings.push(fillings[randNum]); numFillings++; } } for (i = 0; i < sandwhichFillings.length; i++) { sandwhichToMake.appendText(sandwhichFillings[i]); if((i+1) < sandwhichFillings.length) { sandwhichToMake.appendText(", "); } //trace(sandwhichFillings[i]) var myfilling = sandwhichFillings[i]; //trace("myfilling: " + myfilling); myfilling.x = leftBaseX; myfilling.y = leftBaseY - fillingSpacing; addChild(myfilling); } } Reply With Quote November 8th, 2009,03:25 AM #2 Scythe View Profile View Forum Posts 466 posts Mwa ha ha You can't have your sandwich and eat it too. The sandwhichFillings array can be an array of Strings or an array of DisplayObjects, but not both. Strings don't have an x property. DisplayObjects do. Figure out which it is you want.

other Adobe products. Flash Player Runtime Errors and How to Fix Them The following lists common runtime errors found with Flash Player and what you can do to fix them. Also available, Compiler Errors. TypeError: Error #1009 TypeError: Error #1009: Cannot access a property or method of a null object reference. This error occurs when you attempt to access a property or call a method (function) from an object variable that has no value (undefined) or has a null value. If the object is null, it has no value itself meaning it cannot contain any properties. The following example would be a situation where the error would occur: var mySprite:Sprite; // null since not defined trace(mySprite.x); // Error #1009 Because the mySprite variable is null, accessing mySprite.x would be the same as null.x which is not possible, thereby creating the error condition. Note that this behavior is new to ActionScript 3.0. In ActionScript 2.0 and 1.0, doing this would cause a silent failure and return a value of undefined. Usually when this error occurs, it means an error in your code logic. You're code is assuming an object exists when it does not. That is something you will have to identify and fix. This can sometimes be difficult because of the error's ambiguous text; it does not specify what specific object the error is in reference to. However, if you test a debug version of your project in your IDE, it will tell you. Debugging in Adobe Flash Professional: From the File menu, select Debug > Debug Movie. Debugging in Adobe Flash Builder: From the File menu, select Run > Debug [ProjectName]. When debugging (in either Flash Pro or Flash Builder), a Debug version of your project which will include more information about code execution that can help better identify errors. When the error occurs, code execution will pause and the line of code with the error will be pointed out in the code view. Additionally, the Variables panel can be used to inspect the values of the objects and properties within the current scope. If there is a circumstance where it is known that an object may or may not exist, then you would first need to check to see if the object being used has a value before attempting to access properties or call methods from it. This can be handled through a simple if condition. if (mySprite){ trace(mySprite.x); } Alternatively, you can also encase your logi
