Eventual failure to load a font

chipster123 · March 2012

What's the best-practice for loading fonts? I'm getting an error eventually when loading a font within a scene. Maybe it's the way I'm using scenes. The application is the one mentioned here http://www.giderosmobile.com/forum/discussion/528/sudden-need-for-an-user-interface-ui#Item_9 . Each button on a GUI causes the switch to another scene. So there can be a lot of rapid scene changes as the user navigates the application. Fonts are loaded on scene change. Eventually, I get a failure to load a font like:

fonts:/Aclonica-42.txt: No such file or directory.

But this exact font (path and all) is used by this scene successfully many times before it fails.
Any ideas? Should I be loading all the fonts once at the start of the application and reference them from a table?
This happens for both TTFonts and BMFonts.

I have seen that with images as well. I am hoping the fix Atilim mentioned to me is related.

@mykyl66, what fix was that?

How do you specify the path?
I remember there was something like "images/someimage.png" working ok, but "./images/someimage.png" not working on Android and that kind of stuff.

We had issues loading huge tables and part of the error was what you are seeing but with image files in our case. Atilim said he has fixed the issue and it should be out within the next 10 days. (That was a few days ago.) As the error message is similar and not all the time I am making an assumption that this could be related.

Hi @chipster123,

This is an interesting bug. How do you specify path? The bug occurs on player or on exported application? (iOS? Android?)

@atilim, the code looks like

mainMenu = Core.class(Sprite)
function mainMenu:init()
   local font1 = TTFont.new("fonts/arial.ttf",16)
   ...

Using the Player (Linux/Wine).
Additional information, in case it's important: The project has the virtual folder "fonts". The actual .ttf file is in a subdirectory with the same name 'fonts/' within the project's root directory.
