hi there,testing flow3d for a while,
just a question:how can i show a single line text?(like showing fps on screen)
should i use CEgui gadget?
by the way,just curious if flow will support unicode?(cegui can do this,but i think you didn't implement it now),customers from asia can use to show their local text! hope we can see this in the later version!
happy coding!

You would use an Overlay file. I'll get an example of this as soon as I get 5 minutes.

You can use CEGUI. Damien got a quick Overlay example put together today. It will let you print 2D text to the screen without CEGUI.
Overlayexamples.zip
Hope that helps.

Glad we could help. I need to put a page up on the wiki about GUI editors which make CEGUI and overlays much nicer to work with.
Don't know if it's of any interest but there are several usefull GUI related tools, the CEGUI ones improved a lot recently, plus there's a bitmap font tool for ogre which also has CEGUI support.

The default output is basic white on transparent BG in png format so you need to use some kind of image editor to make fancy looking game fonts. Still a very handy tool

Hello again Liverol and Foolish!
I just thought I would chime in with something I am currently working on:
Drawing text to the screen was somewhat of an omission by myself - I just completely forgot that we need a simple helper for drawing to the screen. With the overlay implementation nearing completion, I plan on adding an fG.print or fG.drawText style method that works similarly to the DrawText that Blitz users are used to. This way you do not have to fudge with overlay code for debug output, etc, in the future.
I hope this was of some interest, I will post on my blog when I get a few new helpers finished.

Here's a way to display text using CEGUI (hacked up from one of the other examples): one way of displaying text.

Hello again DiabloV! 
The easiest way to do this would be to create an overlay script and then set the caption of a text area in code. Here is how to do this:
1. In /media/2D Overlays there should be a SingleOverlay.overlay file. This overlay describes a single text area and should be usable for your purposes.
2. You can use code like this to set the caption in the text area of SingleOverlay.overlay:
Import flow.Main
EnablePolledInput()
fG.init()
'Get the overlay specified in the script, then get the main panel it uses.
Global HUD:TOverlay = TOverlayManager.getByName(”SingleOverlay”)
Global HUDMainPanel:TOverlayContainer = HUD.GetChild(”SingleOverlayPanel”)
Global Line1:TOverlayElement = HudMainPanel.GetChild(”SingleTextArea”)
'Make the entire HUD visible.
HUD.show()
'Main Loop
Repeat
'Display 2 test lines
Line1.setCaption(”Test Line 1~nTest Line 2″)
fG.renderWorld()
Delay 16.6666667
Until KeyDown(KEY_ESCAPE) Or fG.AppTerminated()
In the future there will be text drawing helpers built into fG, but right now this is the easiest way to handle drawing text to the screen.
I hope this helps!

Hello again DiabloV!
Yes, I understand that the current method for drawing Text is a bit complicated. I plan to add a simple function for drawing text in the next maintenance release (1.075) in the coming weeks to make this easier.
As for your problem, in order to answer your question, I will need to see the contents of momotext.overlay in order to diagnose the issue. If you can get back to me with that information, I'd be happy to help!
Have a good evening!
Lina
