Font scripts not loading

Post by jakeholes » Tue Jun 26, 2018 7:02 pm

Ogre Version: :?: 1.11
Operating System: :?: fedora 27
Render System: :?: GL

Right now I'm having trouble with font scripts not being recognized as font resources. I'm trying to load in font scripts from a directory using

Code: Select all

		Ogre::ResourceGroupManager &resgroup = Ogre::ResourceGroupManager::getSingleton();
		Ogre::FontManager &fontMan = Ogre::FontManager::getSingleton();
		fontMan.setVerbose(true);
                resgroup.addResourceLocation(font_dir, "FileSystem", "DspaceOgre-fonts", true);
		resgroup.initialiseResourceGroup("DspaceOgre-fonts");
In the font_dir there are .fontdef and .tff files. When I query the ResourceGroupManger for the names of resources in this group, it prints out things like proportional.fontdef and proportional.tff but doesn't recognize that these are fonts. Furthermore the FontManager doesn't recognize that any of these resources even exist. When I try loading a font resource later on the program crashes because they don't seem to have registered anywhere. Any help would be greatly appreciated.

Here is the bottom section of my log output:

can you give an example how your font definitions look like?

note that there were some changes to the format in 1.11 with the new format being:
https://ogrecave.github.io/ogre/api/lat ... ripts.html

there are fallbacks in place that should generate warnings for the old format, but maybe something is broken there..

Thank you that was part of the problem. I was also calling initialise on the resources before the OverlaySystem was being initialised which was also keeping the fonts from loading. Now I see it parsing the scripts and treating the resources as fonts but I now have the odd bug that Ogre is trying to create the resources twice.
When I comment out Ogre::ResourceGroupManager::getSingletonPtr()->initialiseAllResourceGroups(); I get the error that when calling FontManager::getByName("proportional") that the Font Manager returns null having not found the resource. However, when I leave this line I get the error "Resource with name "proportional" already exists" suggesting that this is the second time the resource has been initialised. Do you have any ideas off the top of your head?
I've recreated this duplicate initialization error in a standalone test case by initializing a FontManager before calling initialiseAllResourceGroups. Removing the FontManager initialization fixed it however and I don't initialise the FontManger in the applicaiton I'm working on.

most likely you indeed have "proportional" defined twice somewhere. Try running "grep proportional -R ." in your resource folder.

The font manager is initialized by the Overlay system.

I found my problem. For some reason when using FontManager::getByName, getByName("name") would always return null but if I also specified the group name with getByName("name", "resource group name") it would find the resource.

yes, by default ogre look in the "General" resource group, while your fonts are in "DspaceOgre-fonts"
