input_samplebase(3)

✨ input_samplebase ✨

okay bestie, so this one's from the Arcan Lua API and it's called input_samplebase — it's literally the function that changes the coordinate system origo for a device 🎀 (yes, "origo", that's the word the page uses, we're keeping it 💅)

---

🌸 SYNOPSIS 🌸

nil
input_samplebase( devid, base_x, base_y, base_z )

that's it, that's the whole vibe — nil is the return value, and then the call takes devid, base_x, base_y, and base_z 🦋

💖 DESCRIPTION 💖

so basically: this is primarily needed for mouse devices when you're working with absolute coordinates coming from a device, in the cases where just offsetting where the cursor is drawn isn't enough 😭 like, the simple fix doesn't always slay.

the maybe-easiest case where you'd need this? when mouse input should be locked to a surface and the internal tracking of the device should be shifted if it tries to go outside said surface 🔥 so like, the device keeps its own internal tracking, but you nudge where the origo sits so its coordinates line up with your surface instead of wandering off into the void 💀 no cap, that's the whole point.

🫶 reminder that the page calls it "primarily needed for mouse devices" — don't go inventing other use cases, i'm just relaying the scrolls 📜✨
