ActionScript 3.0 :: Shape Not Appearing From Within A Class Method?
Nov 23, 2010
Im checkin out actionscript for basically first time kind of. Im now looking into creating shapes with actionscript at the same time learning the way actionscript handles oop.
So, here is my problem. Its easy to make a shape, but from within a method of a class, the shape will not appear on the stage. I try the same code snippet in my fla file, and it works fine. Here is the code im using:
I downloaded an Mc Tween Class from [URl] so I can use the ColorTransformTo method. However, the method only works when my movieclip is an image; and I need the method to work when the movie clip is a shape...
I'm working on a simple task/calendar tool where tasks can be added dynamically to a canvas. Here is the main application as defined in Main.mxml, which is essentially just a Canvas and a button for adding a task:
The problem is that when I add a Task instance to the Canvas, the children (the button and label) don't appear. I tried setting creationPolicy="all" on both the Canvas and the BorderContainer, but it still didn't work. I've read a bunch of posts about people having issues accessing members of their class before the class is fully loading, but all I want to do is SEE that Label and Button show up inside the BorderContainer.
I have a mc in my library called SimpleButton and in the class path for that mc I have the path to my class: com.company.ui.buttons.SimpleButton.
But when I try to instantiate the symbol using the following code, it does not appear on the stage.
Code: var simpleButton = new SimpleButton(); addChild(simpleButton);
The code works fine when the mc class path is just SimpleButton, the symbol is added to the stage. However when I try to use my own class, the base class disappears from the linkage box in the mc properties dialog and the symbol does not appear on the stage.
I trying to create a TextField in a Actionscript file, But when I try to create an instance of the class in flash no textfield is appearing. [code]...........
I have two classes. The Main class calls a function, which is defined in a Second class.I'm getting the following error:Error 1120: Access of undefined property myFunctionBasically, I am creating buttons in the Main class that will add a corresponding Child to an Object in the Second class (if you click one button, child x1 will be added, if you click another button, child x2 will be added, and so forth).Here's the relevant code for the Main.as file:
I have a rather silly question but as3's document class always gets me confused.I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).
I would like to be able to call a public method of DocumentClass from GameClass. I don't know how to do that, I tried instantiating an object of DocumentClass within GameClass which simply throws me into an endless loop and after a short while application crashes.
I have a class, my document class, called SilkRoadTweeter. as I also have a class called User.as In my User class I need to call a method called nonce() I have tried this, trace(SilkRoadTweeter(root).nonce()); But I get the error, TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).
I have tried everything and nothing seems to work. How do I do this?
I have a class called Unit. When I use this class in a .fla file, I create it by saying:
var unit00:Unit = new Unit(...);
So then it creates a gfx representation of the screen for me. I would like to have a method like this:
PHP Code:
[code]....
So how do I get this to work? I know that delete this will not work when defined inside the class. How do I target the .fla's instance name when I don't know what it will be called?
My application has a lot of dynamically loaded shapes... Now i am working on an interface to change the color properties of each Sprite. The first idea was a simple colorTransform. But afaik this only allows for transforming the existing colors. I also want to be able to define a NEW fill, i.e. GradientType.LINEAR / RADIAL.
SOLUTION 1: There may be an undocumented method to retrieve a graphics current points. With that i could loop through this Array with lineTo and redraw the current shape with the new solid / gradient fill.
SOLUTION 2: Create a newSprite with the chosen GradientType, size it by currentSprite.getBounds(); and then use newSprite.mask = currentSprite; to fake my desired fill... However, i am afraid of the impact this creates on the application as there may be more than 200 of these Shapes displayed on stage... overlapping each other.
I supposed the constructor would do all the work then. When testing the movie I get no error but no circle was displayed, trace statement put in the class constructor displayed the message ok. When I put the class code directly to the ACTION FRAME, it works fine.
what should I do to get the circle visible in the fla using the FirstCircle class?
They are located in the same package and are both importing each other. I am trying to call a function from Class2 within Class1, but I don't know the syntax. I tried: Class2.godoThisThingNow(); But it gave me an error 1061, call to an undefined method. What's the proper syntax for this, and is it even possible in AS3?
From my LoadXML class I am trying to call a method, named onBackgrLoad, which sits inside the Main class. I made the method onBackgrLoad public. Inside the LoadXML class in the method ParseData I added an event listener. This is supposed to call onBackgrLoad but it doesnt work
I am having some problems regarding image crop.I am able to crop an image but with the use of rectangle class or in rectangular shape.But i would like to crop in circular shape(for example go to URL...).
I drew a line (stepVoltage) in a fla using the graphics class. Once drawn, I want to move it to the right in an update function, but am having trouble. I tride just moving the line with statements like stepVoltage.x = newX; stepVoltage.y = newY; but this didnt work. Then I tried to delete the previous line and draw a new one with a clear () function (see below) but this blocked the next drawn line from showing up.
The code:
var stepVoltage:Shape = new Shape (); stepVoltage.graphics.lineStyle(2,0x000000); addChild (stepVoltage);
So I'm playing with a project where I want my class to be able to use the functionality of the Graphics class without needing to extend Sprite/Shape. My goal aside, I guess I'm confused as to how it works at all? It's methods don't seem to return anything, and since it's added as a child property of the Sprite/Shape classes , I can't seem to figure out what it's actually doing? It's also one of those classes that can't be instantiated.
At this point, I'm just plain curious. EDIT: I should provide more clear distinction of what I'm looking for as answer. I have read the documentation, but the documentation doesn't account for what AS3 is actually doing. I'm looking for educated guesses about the programatic relationship between Graphics and the the classes that use it.
ActionScript Code: package { import flash.display.MovieClip; public class Base extends MovieClip { public var baseHP:int = 50; var newRect:Shape = new Shape();
1046: Type was not found or was not a compile-time constant: Shape. 1180: Call to a possibly undefined method Shape. What does it mean by "undefined method"? I am somewhat of a newby, so sorry if there are any stupid errors
Id like to know if there is a way to do a shape hitTest.Not as the normal hitTest would do, but shape colliding another shape, not the rectangleof a movieclip.It can be in a movieclip.
There is a Point (flash.geom.Point) class in as3.I want to add method to class Point (e.g. convertToStagePointMyMethod()) and I'd like to call this method by using [code]What should I do in order to add this method to class Point? Is it possible without inheritance. I'd like to use it like "partial" classes in .NET
this is a massively simplified version of what I need to do but using the following classes, what do I need to put in the second class to call the function from the first? This class contains what I want to call:
