  • Creating MovieClips with Button States in AS 2.0
    09/24/2008 9:41AM
    Here is a quick tutorial on how to create MovieClips that act like buttons using ActionScript 2.0.  Attached is a sample .fla file with a complete, working example.
    1. Create a new Flash document for AS 2.0
    2. Create whatever graphic/shape that you would like and convert it to a symbol.  Double click on on it with the selection tool, and then press F8 to open the create symbol dialog box, or right click on it and select "Create Symbol".  Make sure that you create it as a MovieClip.
    3. Double-click on the new MovieClip to enter the symbol edit mode.
    4. Rename the existing "Layer 1" layer that contains the base graphic "bg".
    5. Create three new layers above that one in this order:
      1. labels
      2. actions
      3. text
    6. On the labels layer:
      1. Create a keyframe at frame 10, 20, and 30
      2. In frame 1, enter the following label: _up
      3. In frame 10, enter the following label: _over
      4. In frame 20, enter the following lable: _down
    7. On the actions layer create a keyframe at frame 10, 20, and 30 and put a stop(); action in frame 1, 10, and 20.
    8. On the text layer, create a keyframe at frame 10 and 20.
      1. Add the following text to each keyframe:
        1. Frame 1: Steady State
        2. Frame 10: Over
        3. Frame 20: Down
    9. Go back to your main timeline, by clicking on the "Scene 1" button.
    10. Select your MovieClip and give it an instance name of button_mc.
    11. Create a new layer in the main timeline and name it actions
    12. Add the following actions to it:
      1. button_mc.onRelease = function(){
            trace( "Click" );
        }
    13. Test your movie and when you rollover and click on the clip you will see the different states displayed.

  • Creating a Mac/PC Hybrid CD-Rom with Roxio Toast
    08/18/2008 11:03AM
    The following is a quick tutorial on how to create a hybrid CD under Mac OS X. Using Toast, you can fairly easily create a hybrid CD with which the Mac OS will only see Mac specific files and the PC OS will only see the PC specific files.  This preserves the Mac resource fork and icon data as well as the PC icon data.

    1. Create a disk image into which you will place all of your Mac OS files.
      1. Open up the Disk Utility program in Applications/Utilities/Disk Utility.
      2. Click on the "New Image" button in the top bar of the Disk Utility window.
      3. Determine the size of your disk image and create it, making sure it has read/write permissions.
    2. Mount the new disk image and copy any Mac data onto it.  Leave the image mounted.
    3. Fire up Toast
    4. In the left-hand sidebar, click on the "Advanced" button.
    5. Click on the "Custom Hybrid" radio button.  The main Toast window will now display two buttons "Select Mac..." and "Select ISO.."
    6. To add Mac files:
      1. Click on the "Select Mac..." button.
      2. Choose the newly created disk image/Mac volume that you created and into which you copied your Mac files.
    7. To add PC files:
      1. Click on the "Select PC..." button
      2. An "ISO 9660" dialogue box will appear.
      3. Click on the "Files" button and then drag and drop your PC files into this window.
      4. To specify the name of the PC cd as it will appear, double-click on the text to the right of the CD graphic/icon (the default should be My CD).  Enter any new text and hit enter.
    8. Unmount/Eject your Mac data volume before burning.
    9. Burn CD, smile, do victory dance.  :)


  • Using FlashPaper .swf files in ActionScript 2.0
    07/17/2008 4:48PM
    Macromedia Studio 8 shipped with Macromedia FlashPaper 2.0, a pretty cool app that will take PDF and other documents and convert them into .swf files that you can load into other flash/swf applications.

    The following is a quick tutorial on how to load FlashPaper swf files into Flash applications in ActionScript 2.0.
    This tutorial assumes that you know the basics of FlashPaper 2.0 and have a usable FlashPaper .swf file.

    Essentially, you will include an ActionScript file that will provide the functions to allow you to load in and scale the FlashPaper .swf and then include a few configurations and lines of code to load in the FlashPaper .swf.

    First, create a new ActionScript file, save as "flashpaper.loader.as" and copy and paste the following code into it:




    function loadFlashPaperSWF( arg_flashPaper_conf:Object ):Void{
        trace( "\nFrom loadFlashPaperSWF" );
        trace( "arg_flashPaper_conf.flashPaper_SWF " + arg_flashPaper_conf.flashPaper_SWF );
        // Creating the MovieClip into which we'll load our Flash Paper document.
        this.createEmptyMovieClip( "testMovie_mc", this.getNextHighestDepth() );
       
        // callback functions for this clip
        var mcObjListener = new Object();
        mcObjListener.onLoadComplete = function(){
            testMovie_mc._visible = false;
        }
        mcObjListener.onLoadInit = function( arg_target:MovieClip ):Void{
            trace( "running the onLoadInit callback" );
            trace( "arg_target = " + arg_target );
           
            // We'll have to wait until the first page of the flash paper document has loaded
            // before we have access to the FlashPaper API
            // To do so, we'll set up an interval that will check for it's existence.
            // Then run the setSize method
            var var_intervalID = 0;
           
            // Our check function
            function checkFlashPaperLoaded(){
                // Hide the holder clip until it is loaded
                // eval( arg_target )._visible = false;
               
                // Getting a reference to our FlashPaper object
                var var_flashPaperObj = eval( arg_target ).getIFlashPaper();
                trace( "var_flashPaperObj = " + var_flashPaperObj );
               
                if( !var_flashPaperObj ){
                    return;
                }
                else{
                    trace( "We now have access to our FlashPaper API" );
                    clearInterval( var_intervalID );
                   
                    // Resize the doc to fit the size of the stage
                    var_flashPaperObj.setSize( arg_flashPaper_conf.flashPaper_width,
                                              arg_flashPaper_conf.flashPaper_height );
                   
                    // Setting the document to fit to height:
                    // var_flashPaperObj.setCurrentZoom( "page" );
                   
                    // Show it
                    eval( arg_target )._visible = true;
                }
            }
            var_intervalID = setInterval(checkFlashPaperLoaded, 100);
        };
       
       
        // Here we create a new MovieClipLoader Object
        var var_movieClipLoader = new MovieClipLoader();
                   
        // Here we add the listener to our new MovieClipLoader Object
        var_movieClipLoader.addListener( mcObjListener );
               
        // Now we use our new MovieClipLoader object to load the swf into the movieclip holder
        var_movieClipLoader.loadClip( arg_flashPaper_conf.flashPaper_SWF, "testMovie_mc" );

    }




    Then, create a new Flash file (ActionScript 2.0) and add the following to the first frame of the timeline:



    #include "flashpaper.loader.as"

    // ============================================================================
    // Configurations:
    //
    // Our config object
    var obj_flashPaper_conf:Object = new Object();

    // The flash paper swf to load:
    obj_flashPaper_conf.flashPaper_SWF = "files/flashpaper_docs/flashpaper.swf";

    // The width and height of our flashpaper doc
    obj_flashPaper_conf.flashPaper_width = 650;
    obj_flashPaper_conf.flashPaper_height = 320;

    // ============================================================================

    // Loading our Flash Paper SWF
    loadFlashPaperSWF( obj_flashPaper_conf );




    Edit the configurations to specify the location of the FlashPaper .swf and the size that you want it to be displayed and you are good to go.
