I have some code for Flash to simulate moving clouds. It worked under AS1 and now I have updated the FLA file to AS3 and minimum Flash version 10. What is wrong with this code? Can you help see what is wrong with this function?
function createLiquidFlow(target)
{
target.counter = 1;
target.pt = new flash.geom.Point(0, 0);
target.mpoint = new flash.geom.Point(0, 0);
// target.myBitmap = new flash.display.BitmapData(target._width, target._height, false, 0);
target.myBitmap = new flash.display.BitmapData(target.width, target.height, false, 0 );
target.myDispl = new flash.filters.DisplacementMapFilter(target.myBitmap, target.mpoint, 10, 2, 10, 15, "clamp");
target.myList = new Array();
target.myList.push(target.myDispl);
target.filters = target.myList;
target.addEventListener(Event.ENTER_FRAME,
function ()
{
trace("target.name = "+target.name);
trace("target.myBitmap = "+target.myBitmap);
trace("target.myBitmap.width = "+target.myBitmap.width);
trace("target.myBitmap.height = "+target.myBitmap.height);
trace("target.counter = "+target.counter);
var filterList = target.filters;
var offset = new Array();
offset[1] = new Object();
offset[1].x = target.counter;
offset[1].y = target.counter / 2;
target.myBitmap.perlinNoise(45, 6, 3, 50, true, false, 7, true, offset);
filterList.mapBitmap = target.myBitmap;
target.filters = filterList;
++target.counter;
});
}
createLiquidFlow( movieClipLiquid )
I can trace the event listener, but the bitmap and Perlin function appears not to work. There is nothing visually happening in the output SWF. TIA
