Flash 8: attachBitmap

• CyBrain

  I can't get this to work:

  import flash.display.*;
  this.createEmptyMovieClip("bmp1... this.getNextHighestDepth());
  var bmpData1:BitmapData = new BitmapData(980, 280, false, 0xaa3344);
  bmp1.attachBitmap(bmpData1, 2, "auto", true);

  It's verbatim from the Flash help with the exception of the dimensions of my image.

  After publishing Flash 8, AS2, I only get a 980x280 rectangle that hex color(0xaa3344). I have my bitmap image in the library with "bmpData1" in the linkage.

  I assume I'm supposed to do that, but there's no mention of that in the help or in the script.

  My question is how do I get that image in my library to display with this code?

  var linkageId:String = "libraryBitmap";
  var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId...

  Thanks, but I'm still totally in the dark.

  Do I still have to put "libraryBitmap" as the linkage name in my library item (the bitmap)?

  Also, does
  var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId...

  replace my fourth line. If so, shouldn't it read var myBitmapData:new BitmapData = BitmapData.loadBitmap(linkageId...

  What are you trying to do? the idea is that you are loading a graphic bitmap instead of just bitmap data. So you would use it like so ...

  import flash.display.BitmapData;
  import flash.geom.Point;

  var linkageId:String = "libraryBitmap";
  var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId...

  var mc:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
  mc.attachBitmap(myBitmapData, this.getNextHighestDepth());

  mc.onPress = function() {
  var randomNum:Number = Math.floor(Math.random() * 10);
  dissolve(randomNum);
  }

  var intervalId:Number;
  var totalDissolved:Number = 0;
  var totalPixels:Number = 8000;

  function dissolve(randomNum:Number) {
  var newNum:Number = myBitmapData.pixelDissolve(myBit... myBitmapData.rectangle, new Point(0, 0), randomNum, 40, 0x00FF0000);
  clearInterval(intervalId);
  if(totalDissolved < totalPixels) {
  intervalId = setInterval(dissolve, 10, newNum);
  }
  totalDissolved += 40;
  }

  So yes replace this var bmpData1:BitmapData = new BitmapData(980, 280, false, 0xaa3344); which is just data of a bitmap to this

  var linkageId:String = "libraryBitmap";
  var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId...

  linkageId being the linkage name you create in your lib

  Thanks rson. I was just trying to get the image to display.

  I had some down time at work and did some of my first experimenting with the Bitmap Data Class. It's very confusing at first.

  Cool yeah it is a bit confusion but once you start to think about bitmaps or any graphical image in a more programmatically way it makes more sense.
