As3 calls external resource files (swf files and image files)

I. Objectives

1. Use bb.swf in aa.swf.

2. After bb.swf has a dynamic text txt1,aa.swf called, change the display content of this text

 

 

Step 2

Generate the bb.swf File

1. Create bb. fla and add a dynamic text on it. The name is "txt1 ". The initial display of txt1 is "hello"

2. Press Ctrl + Enter to run bb. fla and the bb.swf file will be generated.

 

Call bb.swf

1. Create aa. fla and add the code as shown in the timeline.

Ch ();

Function ch (){
// Call the swf File
Var lr: LoadResource = new LoadResource('bb.swf ', 120,200 );
LR. addeventlistener (event. Complete, CC );
Addchild (LR );

// Call the image part
// Var LR: loadresource = new loadresource ('HTTP: // img1.gtimg.com/gamezone/pics/21519/21519683.jpg',-1,-1 );
// LR. addeventlistener (event. Complete, CC );
// Addchild (LR );
}
Function CC (E: Event ){
// Change the attributes of the MC object in the swf File
Var mc: MovieClip = movi((e.tar get. content );
Mc.txt 1. text = 'bbbbb ';

// Change the display attribute of the image
// E.tar get. content. height = 100;
// E.tar get. content. width = 100;
// E.tar get. content. alpha =. 5;
}

 

Note: The call part of the image is commented out in the code above. If you need to test the call of the image, you can open it on your own.

}

Dispatchevent (E); // throw an "event. Complete" event so that the call layer can perform some additional processing.
}

Private function ioerrorhandler (Event: ioerrorevent): void {

}
}
}

 

 

4. Others

Data Types loaded by Loader:
Loader is used to replace the loadMovie function of the original MovieClip and load external image files and SWF files.

* If an image file (jpg, gif, or png) is loaded, the Data Type of Loader. content is a Bitmap object;
* If the SWF file (flash 9) is loaded, the Data Type obtained by Loader. content is MovieClip;
* If the SWF file (earlier than flash 9) is loaded, the Data Type of Loader. content is AVM1Movie;
