SDL_ALPHA_TRANSPARENT_FLOAT(3)

💖 NAME 💖

SDL_ALPHA_TRANSPARENT_FLOAT — bestie, it's literally the fully transparent floating point alpha value. Zero. Nada. See-through. The ghost of alpha values. 👻

---

✨ SYNOPSIS ✨

okay so here's the whole thing, and yes it's just one line, she's low maintenance like that:

#include <SDL3/SDL_pixels.h>

#define SDL_ALPHA_TRANSPARENT_FLOAT 0.0f

so you pull in SDL_pixels.h and the macro SDL_ALPHA_TRANSPARENT_FLOAT is defined as 0.0f. that's it. that's the post. 💅

🌸 AVAILABILITY 🌸

this macro has been serving since SDL 3.2.0 — so if you're on anything older, no she's not there, sorry babe, upgrade era. 🦋

no cap, that's genuinely the entire page. some macros are main characters with 40 options, this one is a single iconic fact and honestly? respect. 👑

mwah, kisses, this was brought to you by the Simple Directmedia Layer girlies — SDL 3.4.18 edition, with all the love from the SDL3 functions squad. 🫶🎀✨
