Well, there is a warning on whitespaces in the manual. I'll think of something, don't worry.
And there is no font sheet. All you have to do is import a proper TTF font. It's in the "System Resources Importer" menu.
I swear I read the entire thing and couldn’t find it. Maybe I’m just blind :)
Thanks for that heads up about a TTF file - I thought it required a sprite sheet the same way the numbers are. In general (I feel like I’m asking a lot in one thread lol) I would also suggest clarifying the file type the engine expects from certain fields. I didn’t know that little tidbit for instance.
(Edit: welp I tried importing a TTF file and the engine crashed. It did create the proper files in the Fonts folder though. Error log)
The editor applies a filter. It will never let you choose a file it can't use. As for the error - are you sure you've been trying to import _font_ and not an image?
UPD: Nevermind. I checked it, there is a bug. I fixed it, so it will be fixed in the next version. You can actually just add files manually.
Yeah I did import a .ttf file as you instructed.
Anyways, I’m aware of the fact you can manually copy-paste files into the project hierarchy, I just need to know how the engine expects me to call them first - which is what I did after importing dummy fonts and sprites and then changing them accordingly.
