Iterate on world-space XR UI without putting on a headset. Mouse-driven hover, click, drag and scroll through the real XRI interaction chain — zero changes to your scenes, input actions or prefabs.

**Stop reaching for the headset every time you tweak a button.**

XR Mouse Sim lets you test world-space UI in the Unity editor with just your mouse. Enter Play Mode, move the cursor over any world-space canvas, and hover, click, hold-and-drag and wheel-scroll simply work — through the same XRI event chain your players will use on device.

**Native XRI, not mouse emulation hacks**

- Pose is injected via an editor-only ray interactor; select/trigger fire through virtual device state

- Your Select action fires with its own bindings — we never touch your InputActionAsset

- No modifications to your scenes, prefabs, cameras or EventSystem

**Full interaction parity**

- Hover highlights, click, slider drag, ScrollRect wheel scrolling

- Works with your existing XR UI setup (XRUIInputModule + TrackedDeviceGraphicRaycaster)

**Zero-friction setup**

- Auto-spawns in Play Mode inside the editor only — nothing ships in your build (editor-gated, build pollution: zero)

- Project Settings panel: enable toggle, headset gate, camera override, ray distance

- Getting Started window, demo scene and full documentation included

**Honest scope**

- Editor-only tool for Unity 6 + XRI 3.5+. Not a runtime input solution; gamepad/touch simulation not included.
