💖 TTF_SetTextDirection(3) — the SDL_ttf3 functions era 💖

okay bestie, so this one lives in the SDL_ttf3 family of functions, and it's literally about telling your text object which way to flow. yes, direction. we're doing text shaping directions today. slay.

🌸 NAME 🌸

TTF_SetTextDirection — set the direction that's gonna be used for text shaping a text object. periodt.

🎀 HEADER FILE 🎀

It's defined in SDL3_ttf/SDL_ttf.h, bestie. that's the one. go get it.

✨ SYNOPSIS ✨

#include "SDL3_ttf/SDL_ttf.h"

bool TTF_SetTextDirection(TTF_Text *text, TTF_Direction direction);

look at her. iconic signature. 🫶

🦋 DESCRIPTION 🦋

So here's the tea: this function only supports left-to-right text shaping if SDL_ttf was not built with HarfBuzz support. that's the whole vibe check. if you're out here without HarfBuzz, LTR is what you get, no cap. 💅

🌈 FUNCTION PARAMETERS 🌈

  • text — the text you're modifying. the text object itself. the main character.
  • direction — the new direction for text to flow. where's it going? this way, apparently.

👑 RETURN VALUE 👑

Returns true on success or false on failure — and if it fails, call SDL_GetError() for more info, because the error message is not gonna read itself. 😭

🧚 THREAD SAFETY 🧚

Real talk: this function should be called on the thread that created the text. don't be out here crossing threads, it's giving chaos energy and we don't want that. 💀

⭐ AVAILABILITY ⭐

This function has been available since SDL_ttf 3.0.0. so like, it's been here. it's not new new. it's established. 💜
