| 有摄像头才可以试验哦!! 下面是代码:
var cam:Camera = Camera.get(); cam.setMode(cam.width, cam.height, 25); video.attachVideo(cam); var depth_num:Number = 0; var list_array:Array; list_array = new Array(); m = new flash.geom.Matrix(); now = new flash.display.BitmapData(video._width, video._height); out = new flash.display.BitmapData(video._width, video._height); this.createEmptyMovieClip("out_mc", 50); out_mc.attachBitmap(out, 1); out_mc._x = 160; this.onEnterFrame = function() { now.draw(video, m); done = now.clone(); done.draw(before, m, null, "difference"); done.threshold(done, done.rectangle, done.rectangle.topLeft, ">", 4.279309E+009, 4.294902E+009, 16777215, false); list_array.push(done.clone()); if (list_array.length>5) { list_array.shift().dispose(); } var r_num9 = list_array.length; var r_num8 = 255; var r_num7; out.fillRect(out.rectangle, 0); before = now.clone(); for (var c:Number = 0; c<r_num9; c++) { r_num7 = c*r_num8; out.threshold(list_array[c], out.rectangle, out.rectangle.topLeft, "==", 4.294902E+009, -16777216 | r_num7 << 16 | 0 | 0, 16777215, false); } depth_num++; attachMovie("pao_mc", "pao_mc"+depth_num, depth_num+100, {_x:Math.random()*550, _y:Math.random()*400, _xspeed:3-(Math.random()*6+1), _yspeed:Math.random()*3+1, _scale:Math.random()*20+20}); var color:Color = new Color(this["pao_mc"+depth_num]); color.setRGB(Math.random()*0xffffff); this["pao_mc"+depth_num]._xscale = this["pao_mc"+depth_num]._yscale=this["pao_mc"+depth_num]._xscale._scale; this["pao_mc"+depth_num].onEnterFrame = function() { this._xscale += this._scale/60; this._yscale = this._xscale; this._alpha = 166-this._xscale; trace(out.getPixel(this._x, this._y)); if (out.getPixel(this._x, this._y)<=0) { this._x -= this._xspeed; this._y -= this._yspeed; } if (this._x<=0 || this._y<=0 || this._x>=550) { this.removeMovieClip(); } }; }; stop(); |
