Oh my god, thank you it's perfect ! While i'm at it, do you know how to change the font from the codex entry (lorem ipsum) but not the title one ? Thanks again for your time !
I believe you can use
style codex_text:
font "filepath/font.ttf"
Just make sure you add it outside of any screen (so it's not indented, just put it at the bottom of the script and it should be fine)
It's working ! Thank you very much for your time and answers, it was great !
