Hello,

I use a .fnt font created with 1.13 and 1.14 beta versions of BMFont and rendered in jMonkeyEngine.

With both versions I get a visual error when I use outlines and I don't know if this problem is on the Font side or on the jEngine side.

Here you can see the erroneous spacings (see yellow subtitle text and also the h=105.0 text in the upper white text):

The font that I used is the one you can find here:

So I tried using the old "bitmapfonts.exe" from this site: http://www.angelcode.com/dev/bmfonts/

I ran the programm on my old Direct-X-9-Machine and it crashed even before starting. The log.txt holds this information:

So I removed the comic24.fnt font that comes with the test-programm and then it crashed every time after the line with "format: L16".

Can anyone please help?

My next try would be to edit the .fnt text file and add a +6 to each glyph's width (3 pixels of outline) in the hope that this will fix the problem.

If anyone could confirm that the problem is not on my game engine's side but in the created .fnt files, this would help alot - maybe even other users of the angelcode bitmap font generator.

Understood what you wrote and made a workaround for my game:

I created two .fnt fonts - one with outline (font1) and one without outline (font2).

Then, I created two text objects, first text with font1 and second text with font2.

The color of the first text set to black, attach it to the gui graphics of the game.

The color of the second text set to yellow, attach it to the gui graphics of the game.

So, I simulated the "two passes" with overwrites of two different fonts.

Here is an image (see the yellow subtitles):

Okay, I will write a forum post there tomorrow, which will link to this forum post here.

Honestly, I don't know if the original author for .fnt integration is still active in the community. I would fix this myself, if I had the time to work my way through his code.

There are still some visual artifacts when resizing the font, because for whitespace characters his renderer creates a zero-sized quad which then has an outline. Looks very odd when I scale the font up and down, but looks okay for 100% scaling. It might even be, that this particular error is on the .fnt side this time.

I have, however, created my own AngelCodeBMFont class which represents a copy of a .fnt file and can be (de)serialized. This class will be able to merge a current font with another font. For example, my current font doesn't support Arabic, but Chinese+Japanese - so I must mix it with another font. You may remember, that I suggested this once. :)

Well, first: This is great news! Basic technologies should be open and I do also write open source software. My current game will be open for example.

I'm now almost done with my Java implementation of the .fnt merge tool, but I don't know if this can be ported to C++ quickly and easily.

I don't know anything about AngelScript. I know Lua and a little bit of Groovy and Python. Is there a Java-port of AngelScript?

FYI: I made a Font-Merge-Thing for jMonkeyEngine. It works, I tested this idea. :)
