GLUTWARPPOINTER(3)

✨ NAME ✨

glutWarpPointer — moves the mouse pointer to given window coordinates 💫

okay bestie, this is the OpenGLUT window-flavored one, and it's literally just "put the cursor over there" energy. no cap.

---

📚 LIBRARY 📚

OpenGLUT — window 🪟

---

🎀 SYNOPSIS 🎀

#include <openglut.h>

void
glutWarpPointer(int x, int y);

that's it, that's the whole vibe. two ints and a dream 💅

---

🍓 PARAMETERS 🍓

• x — the window X coord for the mouse 🖱️ like, horizontally, where you want the lil guy to land.
• y — the window Y coord for the mouse 🌸 vertically, same deal.

---

💖 DESCRIPTION 💖

so glutWarpPointer() moves the mouse pointer to window-relative coordinates, and those coordinates are the x and y you hand it. that's the whole thing. it teleports the cursor, it does not pass go, it does not collect $200 👑

💀 CAVEATS 💀

ngl there are a few things you need to know before you go warping pointers all willy-nilly:

• x and y are relative to the current window. not the screen, not the universe. the current window. iykyk.
• this is not applicable for GLUT_OFFSCREEN windows 🙈 so if you're in offscreen land, this does not apply to you, bestie.
• warping means moving, fr fr — it's exactly as if the user had manually moved the mouse themselves. which means it can generate mouse-motion callbacks. and here's the spicy part: if your callback then moves the pointer again, you may end up in an endless loop 💀💀💀 not cute. not slay. an actual infinite spiral.
• there's been some discussion about changing this behaviour, but at present it's just a caveat for you, the user, to be aware of. so like… be aware of it 🫶

⚠️ fr fr, if you're warping inside a motion callback, just know the loop risk is real and it's on you to break it.
