SDL_PointInRectFloat(3)

💖 SDL_PointInRectFloat(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the group chat — today we're learning SDL_PointInRectFloat, and honestly? it's giving "tiny function, big main character energy." 🎀

---

✨ NAME ✨

SDL_PointInRectFloat — determine whether a point resides inside a floating point rectangle. 🦋

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_rect.h>

SDL_FORCE_INLINE bool SDL_PointInRectFloat(const SDL_FPoint *p, const SDL_FRect *r);

---

💅 DESCRIPTION 💅

so here's the tea ☕ — a point counts as part of a rectangle if both p and r are not NULL, and p's x and y coordinates are >= the rectangle's top left corner, and <= the rectangle's x+w and y+h.

basically the rectangle is inclusive at the edges, no gatekeeping 💖. so a 1x1 rectangle considers point (0,0) and (0,1) as "inside" and (0,2) as not. not me double-checking the math three times bestie, it's fr fr correct.

🫶 heads up: this is a forced-inline function in a header, and not a public API function available in the SDL library. which is to say — the code is embedded in the calling program, and the linker and dynamic loader will not be able to find this function inside SDL itself. it's a header girlie, she lives in your code, not in the library. periodt. 👑

---

🎀 FUNCTION PARAMETERS 🎀

• p — the point to test. 👀
• r — the rectangle to test. 📦

---

⭐ RETURN VALUE ⭐

returns true if p is contained by r, false otherwise. simple as that, no cap. ✨

---

🌈 THREAD SAFETY 🌈

it is safe to call this function from any thread. go off, multithreaded queen 💜

---

👑 AVAILABILITY 👑

this function is available since SDL 3.2.0. iconic since day one, lowkey. 🌸

---

and that's the whole vibe check, bestie — this page came to you straight from Simple Directmedia Layer, rockin' SDL 3.4.18, in the SDL_PointInRectFloat(3) era. stay floaty, stay inside the rect 💖✨🎀🦋
