ActionScript 3.0 :: Passing A Stage Reference To An Object Placed In The Design View?

Nov 28, 2010

In a game me and a friend are creating, the levels are stored in MCs. In the level MCs there are several other MCs that the player should be able to interact with.

This means the objects in the levels need a stage reference. I can place all the objects manually and pass the stage ref in the constructor of the object's class, but this is a pain when the levels are going to be pretty big.

Is it possible to make sure that flash always passes a stage ref to the object even though it's not placed there by code?

Actionscript 3 :: Design Pattern For Multiple View States?

May 27, 2011

I have an application that takes the user through a set of steps, configuring a product, say about 10+ screens. With options to go back, skip to a certain point etc. I need to fade between these steps, and also have language switches available at any point.

I was thinking of using an MVC style pattern, having a master view that accepts a 'next view' and fades it in, removing the old.

It feels bloated to have 10+ separate view classes, using similar components for this task, so was wondering what other approaches there are that I should look into? or one that is suited for this kind of application

Actionscript 3 :: Keep Both Object And Reference On Stage?

Jun 16, 2011

I have some object, which extends movie clip:public class MyClass extends MovieClip Now, I want to put two of this in the stage:[code]That would put one, but the other I want it to be exactly the same as the first, so I just need to add a "reference" of obj to the stage, along with obj itself.In the end, I want two objects of type MyClass doing the same thing in the stage. If I try to simply do:[code]only obj2 will appear in the stage.How could I achieve that with references? (in order to save memory and CPU time (it is really important))

Actionscript 3 :: Custom Flex Component, Visual Controls In Design View?

Apr 1, 2010

Do you know how if you drag an <mx:Label> or <s:Label> component into your Flex project, when you go to design mode you get this panel on the right to set its properties like text etc.

I have a custom component that I can call with actionscript, or with mxml like this:

<comps:TheComp field1="OK" field2="Yes" />

The component takes this input and uses it for its internal operation

[Code]...

When I go to design mode, I can see the component under custom components, I can drag it to the stage and see it, but can't set its values field1 and field visually on the right like a normal <s:Label> or <mx:Label> would have. how I can add that? Do I need to make it inherit something or anything else

Flash :: Flex - What Are Possible Non-code-related Reasons For A Blank Screen In Builder 4.6 Design View?

Dec 13, 2011

I was editing a very basic mobile Flex project, and after I debugged the master (application) mxml file, Design View stopped working (blank screen displayed, no Design View errors) for all files. Creating new projects, either mobile or else, or testing old, working projects, doesn't work either. Out of the related issues I've found info on, most concern earlier versions of the IDE, and deal with either Design View errors (got none), use of certain functions or custom components (I get the error even on a new project), or are solved by changing styles back-and-forth (tried already, to no avail).

I can't drag and drop components to the design area, either (a "prohibited" symbol appears and nothing happens when I drop); so I'm pretty sure it's not code-related or a bug, but probably something stupid, like a configuration issue, so I definitely need someone to take a fresh look at it.

Flex :: Flash Builder 4 Design View Vs Flash Runtime Appearance W/SDK 4.1?

Jan 22, 2011

Flash Builder's design view is worse than 3's (which at least was usable if you ignore some quirks), so WHAT do Flex UI designers (those who don't have paid design teams...) do to design a complex UI? Because Design View (also based on what a lot of people say about it..) gets more useless with every release.See image for some differences in design view vs.Flash. WHAT is causing this? css also posted..("Duration", "hr", "min" are mx Labels, the image size text is an mx Text comp.Project is an "mx only" SDK 4.1 project.) I don't even care that the spinners look different, I just need it to show me correctly sized stuff so I can position things via Canvas, or properly size containers.

mx|Label {
font-weight:bold;
font-size:12;[code].....

Flash :: Builder 4 "includeIn" Property Causing Design View Error

Apr 26, 2010

I am creating a custom TextInput component that will define an "error" state. I have extended the TextInput class to change the state to "error" if the errorString property's length is greater than 0. In the skin class, I have defined an "error" state, and added some logic to detect the size and position of the error icon. However, if I have this code at the same time I use the "includeIn" property in the bitmap image tag, I get a design view error. If I either A) Only include that code with no "includeIn" property set, it works or B) dont include the code to set the icon size and position and only use the "includeIn" property, it works. Any ideas what could be causing the design view problem when I use both the "includeIn" property and the icon size/position code at the same time?

ActionScript 3 :: Passing Value From One View To Another

Mar 7, 2012

I am very new to actionscript3/flashbuilder and I'm trying to do something simple like pass a value from one view to another view. I worked out all my syntax errors, but I am still getting a NULL error
(TypeError: Error #1009: Cannot access a property or method of a null object reference)
Even though I have the values hard-coded in for testing. I have 2 views, and when I press a button, it is supposed to pass a value to another view which then displays the passed value in a label.

Here are my 2 views:
view1:
<s:View xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark" title="view1">
<fx:Script>
<![CDATA[
var value1:int = 1;

Actionscript 3 :: Flex4.5 - Obtain Reference To View In Class Within ViewNavigatorApplication

Nov 28, 2011

I've got a very simple project in FlashBuilder 4.5. It's a mobile application of type ViewNavigatorApplication with a single view, MapView. In the MapView.mxml file, I've got a Flex component of type Map declared in xml.

[Code]...

In this same project, I've an actionscript class called UserGeolocation. In this class, I'm attempting to get a reference to this map component. So far, I can get a reference to the top-level application, its ViewNavigator and the NavigationStack of said ViewNavigator. However, I cannot find a way to access the MapView, much less the map I've declared within it.

I'm aware of methods like firstView() and activeView(), but I want an absolute solution, one that retrieves the view regardless of whether or not it's first or active. I've tried navigator.getChildByName("MapView") with no luck.

ActionScript 3.0 :: Design Levels Directly On Stage?

Jun 3, 2009

best/easiest/fastest method in AS3 to design game levels (environment) directly on the stage. I'm sure there is multiple methods for this, but let's take a platform game for instance. I'd like to have 30, visually different, spinning wheels all around the stage, and I'd like all of them to have a different rotation speed without having to create a different class for each of them. Is there an easy way I could only place movieclips on the stage where I want them to be, without placing everything with code?

In AS2, I used to put these little variations of code directly on each clip. That way, level designing was pretty easy. All I had to do was to drag the obstacles where I wanted them to be, and simply set their rotation (or any other properties) in their respective code. I'm now having trouble using this method in AS3 since I don't want to place everything with code simple to set a single property. I also don't want to create a class for each different obstacle.

ActionScript 3.0 :: Speed Up Text On Stage Design Area?

Aug 12, 2009

how to speed up the workspace when there happens to be a large amount of text on the stage? I have tried everything I can think of (even choosing outlines only for the layer). It seems to slow down my system even if the layer is not visible. Now doing anything is a chore. I have a pretty fast system, and it's pretty bad that after all these flash iterations I still can't have text on the stage and continue work.

ActionScript 2.0 :: Passing Arguments By Reference?

May 12, 2005

Is it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say

Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.

[code]....

then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?

Actionscript :: Passing Reference Types By Ref - Flex

Jun 30, 2010

I know that in C# when you pass an object (non primitive) to a method the following is true: A reference to the object is passed Changes made to the object in the method are reflected outside of the method. Also, you can pass a reference to a reference in C# e.g this.changeObject(ref myObject);, in which case: Changes to the object and also to the ref are reflected outside of the method e.g. myObject = new new List(); would change the passed objects referred location. Is this possible to do in Flex/Actionscript - can a ref keyword be used?

ActionScript 2.0 :: Passing Array Variables By Value Not Reference

Dec 11, 2006

It took me hours to figure our why this was returning the wrong value - when assigning one array to another it passes by reference not Value. I need a way to force it to pass by values. e.g. copy the existing array and have the second array reference it, so i am free to modify the first array without changing the values of the second.[code]From the example above You see that in Actionscript when assigning one variable to another it does it my reference not value. So when you chage the value of one array it changes the value of the other automatically.I need to have the "test2" variable reference the "test1" array only by value so if modify "test1" the values of "test2" won't be modified.

They are putting the swf files that I have developed into their flex site.The issue that I am having is that within my swf file I need to reference the stage.I do this by "MovieClip(parent).stage"... I do not use the keyword "root", I just reference my swf's root through however many "parent"s i need. It works fine when I publish on my own, outside of their flex site. When it is used in the flex site, they are getting an error that they cannot reference the stage/ stage is null. It is vital that I am able to reference the stage of my swf.
