Away3D Forum Textfields in Broomstick

Textfields in Broomstick Software: Away3D 4.x

alx1507, Newbie Posted: 11 August 2011 03:03 PM Total Posts: 4 Hello all, I’ve done a bit of searching around the forum to see how to do this, and I’ve scraped together a few things but am still unsure on how to proceed. So from what I’ve gathered on the forum this is the process to do it: - create text field. (enable cache as bitmap?) - create bitmap data var. - do a bitmapDataVar.draw(textFieldName, null, null, null, null, true); - assign new bitmap data to a material. - apply material to a plane or something. This leads to nothing but a black texture with no text. So here is my actual code: bitText = new TextField(); bitText.name = "mtfsdfd"; bitText.text = "tessssssssssssssssssssssssssssst"; bitText.autoSize = TextFieldAutoSize.CENTER bitText.x = stage.width/2-37 ; bitText.y = 170; bitText.selectable = false; bitText.border = false; bitText.mouseEnabled = false; bitForm = new TextFormat(); bitForm.color = 0xffffff; bitForm.size = 23; bitForm.font = "helvetica"; bitForm.bold = true; bitText.setTextFormat(bitForm); var btmd:BitmapData = new BitmapData(256,256,true,0xffffff); btmd.draw(bitText,null,null,null,null, true); var erthMat : BitmapMaterial = new BitmapMaterial(btmd,true,false,true); Any help would be fantastic! Thanks, Alex

To make sure your BitmapData looks correct, you can also view it on screen in a Bitmap: `var bm:Bitmap = new Bitmap(btmd); addChild(bm);` The error must be somewhere else in your code. Are you for example triggering a view.render()? That’s a common mistake, that you comment out the function that actually renders the view. Alternatively your camera may be looking at the reverse side of the plane, which appears black even with bothsides=true, if your scene contains lights. Post more of your code, I’m sure there’s just some simple mistake. cheers!

I was originally attempting this on a sphere that I had in the scene already, and I guess it was wrapped in just the right way to be hidden from me. I applied it to a new Plane primitive and it appeared! The primitive still has a solid black background behind the text, is there any way for me to make that transparent? Would it be smarter to be working with a Sprite3D? Thanks again for the help! Alex
theMightyAtom, Sr. Member Posted: 11 August 2011 04:50 PM Total Posts: 669 [ # 3 ] There’s code examples of the two transparency methods in this post. http://away3d.com/forum/viewthread/414/ Basically, alphaThreshold is the prefered way, but it can produce jagged edges. You set a threshold, and all alpha values under that number (0-1) are 100% transparent, all over the threshold are 100% opaque. The other method, alphaBlending=true will give you a nice looking result, though can in some circumstances give unexpected z-sorting. You will find links to long explanations in the other post.
