SDL_GetRectIntersection(3)

✨ SDL_GetRectIntersection ✨

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, page SDL_GetRectIntersection(3) 💖

🌸 NAME 🌸

SDL_GetRectIntersection — Calculate the intersection of two rectangles. that's it, that's the whole job, and she does it flawlessly 💅

---

🎀 SYNOPSIS 🎀

#include <SDL3/SDL_rect.h>

bool SDL_GetRectIntersection(const SDL_Rect *A, const SDL_Rect *B, SDL_Rect *result);

🦋 DESCRIPTION 🦋

so here's the tea, bestie: you hand her two rectangles and she figures out where they overlap and drops that overlap into result. iconic behavior honestly.

BUT — and this is the important part — if result is NULL, then this function will return false. no result to fill, no vibes to give. she's not about to write into the void, periodt.

---

💜 FUNCTION PARAMETERS 💜

• A — an SDL_Rect structure representing the first rectangle. the first bestie 🫶
• B — an SDL_Rect structure representing the second rectangle. the other bestie 🫶
• result — an SDL_Rect structure filled in with the intersection of rectangles A and B. this is where the magic lands ✨

---

👑 RETURN VALUE 👑

Returns true if there is an intersection, false otherwise. so like... did they overlap or not. yes or no. slay or not slay. that's the whole answer 😭

---

🌈 THREAD SAFETY 🌈

It is safe to call this function from any thread. she's polyamorous with threads and she's thriving 💚 no locks, no drama, no gatekeeping.

---

⭐ AVAILABILITY ⭐

This function is available since SDL 3.2.0. if you're on anything older she simply does not exist yet, sorry babe 🙈

🔥 SEE ALSO 🔥

• SDL_HasRectIntersection(3) — the girl who just tells you whether they overlap without giving you the receipts. sometimes that's all you need, iykyk 💅
