al_set_fallback_font(3alleg5)

💖 al_set_fallback_font(3alleg5) 💖

okay bestie, welcome to the al_set_fallback_font(3alleg5) page of the Allegro 5 manual — yes that manual, the one from the allegro5 family of manpages. sit down, hydrate, and let's talk about what to do when your font is missing a glyph 🫶

---

✨ SYNOPSIS ✨

like, the actual signature, no cap:

#include <allegro5/allegro_font.h>

void al_set_fallback_font(ALLEGRO_FONT *font, ALLEGRO_FONT *fallback)

two pointers, one job. iconic behavior honestly 💅

---

🌸 DESCRIPTION 🌸

so basically: this function sets a font that gets used instead whenever a character isn't present in the font you're drawing with. like, your main font ghosted that glyph, so the fallback font steps in and covers for it. main character energy from a backup font, we love to see it ✨

• you can chain fallback fonts — font A falls back to B, B falls back to C, etc., it's giving relay race 🏃♀️
• but make sure there is no loop, because a loop would crash the application! 💀 fr fr, do not do that, that's not a vibe
• and if you wanna remove a fallback font again? just pass NULL. poof, gone, no more fallback, bye 🎀

⭐ SINCE ⭐

5.1.12 — so if your Allegro is older than that, this one's not for you bestie 😭

👑 SEE ALSO 👑

• al_get_fallback_font(3alleg5) — the getter, so you can peek at what's currently set 👀
• al_draw_glyph(3alleg5) — drawing a single glyph, the whole reason fallbacks matter
• al_draw_text(3alleg5) — drawing actual text, where the missing-character drama unfolds 🌈

---

lowkey reminder: chained fallbacks = fine, fallback loops = 💀. NULL removes. that's the whole tea.

and that's the page!! this was the Allegro reference manual version of al_set_fallback_font(3alleg5) — go forth and give every glyph a home 🦋💜
