ActionScript 3.0 :: "toString" Returns A String - More Classes?
Dec 10, 2009
It seems as thought whenever you try to treat a class as a String (such as putting it inside of trace() or similar), if that class has a "toString" function, it will get the string from whatever that function returns, and will otherwise return something along the lines of "[object MyClass]".
Are there any more of these special functions?
Also, a bit of a far stretch, is there any way to do this with custom classes, for instance, your class may be a PolarPoint, but people can call "toLinearPoint()" and get an instance of a class which is a LinarPoint but with the same data.
Now, this is simple enough to do manually, but let's say you pass in the PolarPoint in a function where a LinearPoint is expected. Is it possible to make Flash automatically run the toLinearPoint() function if found? Similar to how Flash will run toString automatically if passed in as a String somewhere.
That second part is probably more of a hassle than it is worth though, but it would be REALLY handy if you are unable to extend two classes at once, but want your class to be able to be treated as both.
this function bellow returns the String for display in an item renderer.
[Code]...
But i am blocked about the public function set selectedLabel(label:String):void is there anyone who know a function labelToItem or another solution to set my combobox selectedLabel
I have a load file and a write to file method. We all know what they do. How ever load always returns true and write always returns false....Right there you know somethings wrong. Because The forums have an issue with me posting code...I posted it here: [URL] Based on this code what is the issue here? why is write always returning false and why is load always returning true? (even for files that do not exist). My understanding is that if flash cannot find the file it should write to it will create it and if it cant load said file, then that method should return false.
There's a part of as3 that i've not quite learned yet. maybe it's not good practice to do, but i'm trying to instance classes without having to specifically write their names in the code.In essence, i want to have a string containing the name of a class (in this case, "Pistol") and i want to be able to use that variable, to create an instance of that class. Presumably using new. I'm not exactly how to go about resolving a string into a classname though.
I'm having with a menu navigation system. I'm using Flash MX. I have created a menu system for the site I'm building ([URL]) where one of the buttons "Choose photographer" drops down a list of names. All the other buttons just jump to another page. The drop down is currently using tweens also the logo moves to the left as the dropdown appears and returns when the dropdown returns. All working fine apart from its a bit jerky.
It's I just wanted to get away from tweening and use action scripts instead, as I'm a newbie to all things Flash I trawled the net for tutorials and examples so that I could cobble together the exact same effect. I have managed to get the drop down work and return using the action script and it does seem smoother and works slightly better. But can I get the logo to move to the left and back in time with the drop down...no.
I have a bit of text "this is the text want I want to do is replace the text, I have just added another is for good measure".This is stored as a standard string but I want to turn this into html and add css classes like, in this example wrapping around the word "is"; "this is the text want I want to do is replace the text, I have just added another is for good measure"
I have an array which has strings for the key instead of numbers. when i use .toString() on this array, it does not output a string, leading me to believe that .toString only works when you have numerical keys. Is there an easy way I could compare two of the above arrays?
I've looked in the user manual and I can't find any reference to toString() for syntax information. Isn't there a parameter for me to use to specify the string lenght? And whether to add leading zeros or not?Here's the code I need to add leading zeros:
playbutt.addEventListener(MouseEvent.CLICK, playSound); function playSound(e:Event){ SoundMixer.stopAll(); var num:Number = Math.ceil(Math.random()*43); bigNum.text = num.toString(); var path:String = "Track No" +
We have a lot of objects for which we like to implement a simple toString to output attributes of the object. Some of these attributes may be complex objects themselves. Is there any standard, or simply just a best practice for a style? I'm thinking something like: [SimpleClassName] { prop1:value, prop2:value }
In which case a nested value would look like: [SimpleClassName] { prop1:value, prop2:[NestedObject] { prop3:value}} We are using Java but I find myself asking the same question in most languages!
Is it fine to display the output of Array.toString() to the user, or is there a possibility that the string format could change in future versions of ActionScript 3 or other compilers?
I'm doing a AS3 project in Eclipse and trace alot of values. I though it would be nice to have a toString() function in every class, at the bottom of each class as the last function, but i dont want to do this by hand for 500+ files. Is there a quick and good way of doing this automated?
I have the actionscript code here for a bubble popping game. When the game starts, bubbles fall down from the top of the game to the bottom and score is kept for the most bubbles clicked or popped in 30 seconds.The size of the bubble is defined by the initialize method in the code, and uses ToString() to calculate the score. ToString gives me a 1061: Call to a possibly undefined method Random through a reference with static type uint. This error which I cannot figure out where it comes from.[code]
im going through ASDG, page by page, and learning everything from scratch. he's explaining datatypes, i.e. strings, numbers, booleans, arrays, etc...i get that. then he goes into explaining how to convert datatypes from numbers to strings using "toString" , and then strings to numbers using "Number()"...and then later, strings to booleans and stuff. My question is this. where someone would want to turn a number into a string or a string into a number? and how would someone even turn a string into a number? i dont understand how that works.
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).
I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
inheritance and building classes from other classes.
I have 3 classes: gfxRoomText - changeable colour gfxRomInter - changeable colour - interactive gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
I have to use many custom classes for a project, each class includes lots of elements(methods,properties) and I generally forget their names when coding. Is there any editor which I can enumarate the elements of my classes after pressing "." like Flash's built in classes?
I am new to classes and I am just starting to follow tutorials on how to assign classes and sub classes and I am wondering when you assign a base class or class to an object(Symbol e.g movieclip) through the properties, are all instances on the stage no matter how many and what they are named influenced and is the Stage/main timeline always the parent? and just one more question, is the parents objects display list all the movieclips that are used on the stage or all the instances on the stage?
