And yes, if you do not use namespaces the class name is enough. Follow these steps In flash, mark your class for export by bringing up "Properties" for the library item and checking "Export for ActionScript" and giving it a "Class" name.
Publish Resources. We use one SWF then as dataContainer for all the assets, the base swf loads the dataSWF and from then on the assets are accessible and can be instantiated. Imagine we have one simple SWF eg : data. As you know, in Flash CS3 a class is automatically generated when you not specify a custom class so in our SWF we can normally instantiate a Square object by writing this code:.
But imagine that we have another SWF eg: base. Thats were the technique of dynamic class loading comes in. As you can see we call the onLoaded function when the data. The onLoaded function is the place where we are going to access the SWF his contents, in our case the Square in the library.
The final onLoaded function looks like this:. As you see we first instantiate a class object and we acces the Square class inside the library of the data. From then on you can instantiate as much squares you want. The last thing we do is adding the square to the displayList by calling the addChild method. Pingback: Bram. I can load swf1, create a new CustomButton and add it to the stage to see it render. I then remove and destroy the custom button instance, then unload swf1. Finally, I load swf2, create new CustomButton and add to the stage.
Considering the platform, the surely is a way to solve the problem with just the Flash IDE, right? Tracing the nested clip yields undefined. Anybody have an idea how to access this nested clip? Pingback: import external classes at runtime!! Do I need to make them as MovieClip only. JM do you get any solution for your problem? Than a Lot n Lot. Just been trying this out independently and came across this post. Basically I have a load of SWFs with different assets in them.
So I load them in and then I can access the asset classes. But… it gets really boring having to type out all of the gefDef stuff for each class. Anyone found a way to do this?? That way the new definition will be kept separate from the old one. This will work:. Hi Koen and thanks for the info. I am particularly curious as to how to cast the square to a custom class that extends MovieClip or Sprite for that matter.
I am repeatedly finding that casting to a Custom Class results in square being returned as null? I have a Widget class defined in the parent and child SWFs. This means that SWF files containing embedded data, such as images and sound can be loaded, but not SWF files containing executable code. Loader objects are used to load SWF files and graphics files into an application. The Loader class is a subclass of the DisplayObjectContainer class.
A Loader object can contain only one child display object in its display list—the display object representing the SWF or graphic file that it loads. When you add a Loader object to the display list, as in the following code, you also add the loaded child display object to the display list once it loads:. Once the SWF file or image is loaded, you can move the loaded display object to another display object container, such as the container DisplayObjectContainer object in this example:.
Once the file has started loading, a LoaderInfo object is created. A LoaderInfo object provides information such as load progress, the URLs of the loader and loadee, the number of bytes total for the media, and the nominal height and width of the media.
A LoaderInfo object also dispatches events for monitoring the progress of the load. The following diagram shows the different uses of the LoaderInfo object—for the instance of the main class of the SWF file, for a Loader object, and for an object loaded by the Loader object:. The LoaderInfo object can be accessed as a property of both the Loader object and the loaded display object.
As soon as loading begins, the LoaderInfo object can be accessed through the contentLoaderInfo property of the Loader object. The loaderInfo property of the loaded display object refers to the same LoaderInfo object as the contentLoaderInfo property of the Loader object. In other words, a LoaderInfo object is shared between a loaded object and the Loader object that loaded it between loader and loadee. In order to access properties of loaded content, you will want to add an event listener to the LoaderInfo object, as in the following code:.
For more information, see Handling events. When you load an external file into Flash Player or AIR through the load or loadBytes method of the Loader class, you can optionally specify a context parameter. This parameter is a LoaderContext object. The LoaderContext class includes three properties that let you define the context of how the loaded content can be used:. If you set this property to true , the Loader checks the origin server for a policy file see Website controls policy files.
This is necessary only for content originating from domains other than that of the SWF file containing the Loader object. If the server grants permission to the Loader domain, ActionScript from SWF files in the Loader domain can access data in the loaded image; in other words, you can use the BitmapData.
Specify this for a SWF file from a domain other than that of the file containing the Loader object. When you specify this option, Flash Player checks for the existence of a policy file, and if one exists, SWF files from the domains permitted in the cross-policy file can cross-script the loaded SWF content. You can specify flash. When loading the file, you can specify that the file be included in the same application domain as that of the Loader object, by setting the applicationDomain parameter to flash.
By putting the loaded SWF file in the same application domain, you can access its classes directly.
