3DSprite with transparent background Software: Away3D 4.x

TrueSign, Member Posted: 14 August 2012 09:03 AM Total Posts: 57 Hi, I need a pop up scores appearing in 3d space. How can I create a points in 3d space in Away3d 4 ? I don’t want to create 3D object for every number. Right now I’m using Sprite from flash library: `_pointsMc.pointsTxt.text = point; //_pointsMc is flash library symbol var _bitmapData:BitmapData = new BitmapData(32, 32, true); _bitmapData.draw(_pointsMc, null, null, null, null, true); var bitmapPointsTexture:BitmapTexture = new BitmapTexture(_bitmapData); _pointsMaterial = new TextureMaterial(bitmapPointsTexture); _points = new Sprite3D(_pointsMaterial, 10, 10); _view.scene.addChild(_points);` but I can’t make it transparent. Background is always there. Is there an easier way to put pop up scores on stage? Any ideas how can I do that? You can see my project here: http://www.truesign.ie/sheeping/ Thanks

TrueSign, Member Posted: 14 August 2012 03:35 PM Total Posts: 57 [ # 3 ] Thanks ! Both solutions working fine. I have tried alphaBlending set to true before but I haven’t set argb in bitmap data: _bitmapData:BitmapData = new BitmapData(32, 32, true,0x00000000); Working just fine now. Thank again.
