Custom font(s) not working? (XML)

[Cube_]

I tried loading a custom font.
the loading seems to work. but whenever font->draw is called the application crashes.

I am positive I did it correctly! (Doesn't REALLY matter though. I will be using this font as the only font anyway. so I could just repalace it....)

[CuteAlien]

You neither tell us anything about your code nor do you even post the font-file which crashes. I suppose the only way we can help you is using magic...

[Cube_]

ok. I will post everything for now. sleep. **Posting first thing tomorrow!**

as I promised. here is the code:

The program will show how to use the
basics of the VideoDriver, the GUIEnvironment and the

irrlicht.h, which can be found in the Irrlicht Engine SDK
directory \include.

In the Irrlicht Engine, everything can be found in the namespace
'irr'. So if you want to use a class of the engine, you have to
write an irr:: before the name of the class. For example to use
the IrrlichtDevice write: irr::IrrlichtDevice. To get rid of the
irr:: in front of the name of every class, we tell the compiler
that we use that namespace from now on, and we will not have to
write that 'irr::'.

Like the irr Namespace, we do not want these 5 sub namespaces now,

and for some reason I can't attatch files... so you'll have to live without the font. (Though it was created using the font tool that comes with irrlicht. I used the font Stencil with anti-aliasing and no alpha.

[randomMesh]

Try to check if the path of the font is valid.

Code: Select all

 
IGUIFont*font = guienv->getFont("Arial.xml");
if (!font) { printf("Font not found!\n"); device->drop(); return 1; }
 

And please post a MINIMAL compilable example next time. There's no point to post code of an event receiver when you got problems with font loading.

[Cube_]

ah well.. I was a bit lazy with that....
so I posted the whole file
and it can find the font.

[CuteAlien]

That code works with the xml font coming with Irrlicht (media/lucida.xml). So can't tell what's wrong without the font-file. You can mail files directly to us - check my sig for my homepage and there you can find my mail-address in contact (sorry, avoiding to post it here due to spam).

edit: I never used the fonttool so far, but I've seen several threads in the past from people figuring out how to export fonts correctly. So please search the forum for other reports on the fonttool, it could be something about the export-settings.

[Cube_]

I'll mail the font to you. I don't see any errors myself, but I might just be overlooking it ^^*
I don't have the font on this computer... I'll mail it to you @ 18.00 GMT+1 (Central Europe Time) or something around that.

[CuteAlien]

Lol at mail arriving at @ 18.00 GMT+1, I'll be watching my mail-inbox with bated breath :-) But please (!) do first what I wrote above - check the forum and look which problems others had - I'm nearly certain this is an export settings thing. And only if that fails send me te font - and if you do so - send me also the font from which you generated it so I can try it myself in the font-tool.

[Cube_]

ok, I'll search.

[Cube_]

can't find anything. mail'd

[CuteAlien]

Your font-files together with your code above work here (after renaming the xml to Arial.xml). Are you sure you have both files in your folder when starting your application?

[Cube_]

yes.
I am positive. could I have called it wrong?
or could my irrlicht dll be corrupt?

[CuteAlien]

I have no idea - I didn't do anything special. Just copied your code from above, fixed the includes (as "q3factory.h" and "sound.h" are not part of this...) and copied the xml and the bmp beside the executable. I used svn trunk - I can maybe try again with 1.7 in the evening.

Just set a breakpoint and check if the font loads.

[Cube_]

I should. and thanks anyway.
and those includes are there for a later use, I just included them so I wouldn't forget.
