是否原创：否
转自何处：http://www.senocular.com/flash/source/?entry=760
AS版本：AS2
前期准备：需要在舞台上放置一个影片剪辑，并设定实例名为f_mc
效果预览：

移动鼠标，可以看见效果

AS代码：
  1. Stage.scaleMode = 'noScale';

  3. // import flash filters
  4. import flash.filters.*;

  6. // define a maximum distance value for the bevel
  7. var maxbeveldistance:Number = 5;

  9. // create the bevel filter
  10. var bevel:BevelFilter = new BevelFilter();
  11. // give the bevel a strength of .6
  12. bevel.strength = .6;

  14. // create a dropshadow filter
  15. var dropshadow:DropShadowFilter = new DropShadowFilter();
  16. // apply dropshadow filter settings
  17. dropshadow.color = 0x000000;
  18. dropshadow.alpha = .75;
  19. dropshadow.blurX = 10;
  20. dropshadow.blurY = 10;

  22. // update the filters when the mouse is moved
  23. onMouseMove = function(){

  25. // find the difference of location of the
  26. // mouse from the center of f_mc
  27. var dx = _xmouse - f_mc._x;
  28. var dy = _ymouse - f_mc._y;

  30. // determine a distance
  31. var distance = Math.sqrt(dx*dx + dy*dy);
  32. // determins an angle (in radians)
  33. var angle = Math.atan2(dy, dx);


  36. // apply distance and angle to bevel filter
  37. // do not let bevel.distance go above maxbeveldistance
  38. // dividing distance by 50 keeps it reasonable
  39. bevel.distance = Math.min(maxbeveldistance, distance/50);
  40. bevel.angle = 180 + angle * 180/Math.PI; // convert and rotate 180 degress

  42. // apply distance and angle to dropshadow filter
  43. // dividing distance by 20 keeps it reasonable
  44. // note that this is slightly different than the
  45. // divisor used for the bevel filter
  46. dropshadow.distance = distance/20;
  47. dropshadow.angle = 180 + angle * 180/Math.PI; // convert and rotate 180 degress

  49. // add the filters to the f_mc movie clip, bevel first
  50. f_mc.filters = [bevel, dropshadow];
  51. }

  53. // initiate
  54. onMouseMove();
