InspectorPanel shows EditorState.Selected's Transform (Position/Scale as
draggable Vector3 widgets, Rotation shown read-only as a quaternion — a
real rotate control needs Euler conversion or a gizmo, out of scope for
just the Inspector) and, below it, every attached Component's public
fields via reflection. No per-component-type drawer code exists anywhere:
int/float/bool/string/Vector3 fields get a live-editable widget, anything
else falls back to a read-only ToString(), and a brand new component type
in any plugin gets an Inspector for free the moment it's attached — that
genericity is the entire reason to do this by reflection instead of a
registry.
Field edits write straight back through FieldInfo.SetValue, same gap
GameObject.AddComponent's doc comment already names: components are plain
fields with nothing to intercept a direct mutation, so this needs no
SystemAccessScope declaration any more than a hand-written `component.
Value = 5` would.
EditorPlugin now defaults EditorState.Selected to the first root once,
if nothing's been clicked yet — an empty Inspector on every fresh launch
had nothing useful to show. Verified by screenshot: Inspector displays
"Quad"'s real Position (0,0,0) and Scale (2,2,1), matching scene.json
exactly, plus a QuadRenderer header correctly showing "(no fields)" since
it has none yet.
Full suite still green: 65 tests.
