Pointer Probe

A scene usually has several things that want to know what sits under the pointer: a formation slot to glow, the ground an aim lands on, a unit to outline. Each one casting its own ray means several raycasts per frame and several answers to the same question. PointerProbe is one raycast the whole scene shares, and it knows when the pointer is on UI so none of those readers has to.

What it does

  • One RaycastAll per frame from the pointer, with the union of every reader's layers, sorted by distance.
  • Nothing is hit while the pointer rests on a picking element of a live screen-space view. World-space panels never count.
  • Pointer position and primary-button edges for the frame, so a drag can run off the probe.

Setup

Add PointerProbe to a scene object and hand it to the readers (a scene service provider is the natural owner). Readers register the layers they care about once:

csharp
_probe.IncludeLayer(slotLayer); _probe.IncludeMask(groundMask);

Reading

csharp
// the nearest hit carrying a component (or an interface) on itself or a parent if (_probe.TryGetFirst(out FormationSlot slot, out RaycastHit hit)) { ... } if (_probe.TryGetFirst(out IWorldDropTarget target)) { ... } // the nearest hit on a layer mask if (_probe.TryGetFirst(groundMask, out RaycastHit ground)) { ... } // the nearest collider changed (including to or from none) _probe.TopChanged += Refresh; // this frame's pointer in a panel's coordinates Vector2 inPanel = _probe.PointerInPanel(root.panel);

ScreenPosition, PrimaryPressedThisFrame, PrimaryHeld and PrimaryReleasedThisFrame describe the pointer this frame. OverScreenUI says whether the probe skipped the cast.

Pointer over UI

The gate the probe uses is public:

csharp
if (LunaUIManager.Instance.IsPointerOverView(screenPosition)) return;

Every UIView registers with the manager on construction, so the answer follows views as they open and close. Use it in any scene reader that must not act while the pointer is on the HUD (click-to-move, hover highlights).
