trouble importing custom bitmap fonts

Former Member over 10 years ago

Hi, I've having difficulty importing and displaying bitmap fonts.

I can create .png and .fnt files and file them under
/resources/resource/fonts/<myfont>.png
/resources/resource/fonts/<myfont>.fnt

Then I update my resources.xml file as such
<resources>
<fonts>
<font id="id_<myfont>" filename="fonts/<myfont>.fnt" filter="0123456789" />
</fonts>
</resources>

And load the resource
font = Ui.loadResource(Rez.Fonts.id_<myfont>);

But it still won't display when I
dc.drawText((width/2),(width/2),font,"12",Gfx.TEXT_JUSTIFY_CENTER);

Nothing is overlapping. Colors are not the same as the background. I can swap "font" with Gfx.FONT_MEDIUM and it will work just fine.

Any ideas? Am I missing something? How might I best approach debugging this issue? Thanks!

It is funny because I actually have the same problem as you do. Everything in place, the code compiles just fine, but the text simply does not show up. It looks like this:

Any ideas?

remove the extra resource folder

/resources/fonts/<myfont>.png
/resources/fonts/<myfont>.fnt

.. and the extra xml tags

<resources>
<font id="id_<myfont>" filename="fonts/<myfont>.fnt" filter="0123456789" />
</resources>

remove the extra resource folder

/resources/fonts/<myfont>.png
/resources/fonts/<myfont>.fnt

The extra resource folder won't matter as long as the base folder starts with "resource".

.. and the extra xml tags

<resources>
<font id="id_<myfont>" filename="fonts/<myfont>.fnt" filter="0123456789" />
</resources>

This is my guess as to why it's not working for you. Does removing the "<" and ">" form your ID get things working?

Are you having Friday drinks?

oops, sorry guys bad example? my actual code doesn't use <myfont>, it's the actual font name.

As in the Analog sample code, which I modeled after:
/resources/resource/fonts/blackdiamond_0.png
/resources/resource/fonts/blackdiamond.fnt

<resources>
<font id="id_font_black_diamond" filename="fonts/blackdiamond.fnt" filter="0123456789" />
</resources>

but if I use my own font it doesn't work..

Do the characters in the png need to be in a specific position, size, or format? I would assume the .fnt file specifies all of that for the program..

what does your .fnt file look like? It should be a text file.

If I remember rightly you need a minimum of 12 characters, and the char sequence must be in order. So map 48 - 57, change the 32 to 47 or 58, and add 1 more at the end. You can exclude the kernings value. If you don't need all 12 chars then you can still map in less.

Resolved: I have it displaying custom fonts now. Thank you all for your help!

I added additional chars and reordered the .fnt chars and it still wasn't working/ Once I restarted Eclipse it worked!
