feat(ui): #15 migrate DebugOverlay to ImGui DebugPanel - 7 collapsing sections + diagnostics toggles
Replaces the 473-LOC custom-StbTrueTypeSharp DebugOverlay with an
ImGui-rendered DebugPanel using the I.1 widget extensions. Single
window with 7 CollapsingHeader sections; checkboxes are the primary
toggle surface; F-keys retained where they invoke real gameplay
actions, dropped where they only toggled panels.
Pieces:
- DebugVM (UI.Abstractions): read-through ViewModel with combat-event
ring (cap 25), toast ring (cap 25), 4 diagnostic-flag bools
(DumpMotion / DumpVitals / DumpOpcodes / DumpSky), 3 Action hooks
(CycleTimeOfDay / CycleWeather / ToggleCollisionWires). Self-
subscribes to CombatState.DamageTaken/DealtAccepted/Evaded* /
Missed*/AttackDone/KillLanded - replaces the old BindCombat path.
- DebugPanel (UI.Abstractions): one ImGui window with sections
Player Info, Performance, Compass (text-only - draw-list strip
deferred to D.6), Help (BeginTable cheat-sheet), Combat events
(TextColored by kind: Info=yellow, Warning=red, Error=deep red),
Recent toasts, Diagnostics (Checkboxes for the 4 flags + Buttons
for the 3 cycle/toggle actions).
- All 28 Snapshot data points covered: Fps, FrameMs, PlayerPos,
HeadingDeg, CellId, OnGround, InPlayerMode, InFlyMode,
VerticalVelocity, EntityCount, AnimatedCount, LandblocksVisible,
LandblocksTotal, ShadowObjectCount, NearestObjDist, NearestObjLabel,
Colliding, DebugWireframes, StreamingRadius, MouseSensitivity,
ChaseDistance, RmbOrbit, HourName, DayFraction, Weather,
ActiveLights, RegisteredLights, ParticleCount.
- GameWindow surgery (+252/-165): removed _debugOverlay field +
snapshot builder block + Update/Draw calls; added _debugVm /
_debugPanel construction in the if (DevToolsEnabled) block;
added per-frame nearest-object scan cached for VM closures
(zero cost when devtools off); helper methods CycleTimeOfDay /
CycleWeather / ToggleCollisionWires / GetDebug* / GetActiveSensitivity.
F-key disposition:
- F1: repurposed - now toggles whole DebugPanel visibility.
- F2: kept - ToggleCollisionWires (also a Button in panel).
- F4 / F5 / F6: REMOVED - per-section toggles replaced by
CollapsingHeader inside one window.
- F7: kept - CycleTimeOfDay (also Button).
- F8 / F9: kept - mouse-sensitivity adjust; toasts route to
_debugVm.AddToast.
- F10: kept - CycleWeather (also Button).
DebugOverlay.cs DELETED (473 LOC). TextRenderer + BitmapFont kept
alive: UiHost references _debugFont and the future HUD-in-world
(D.6) will reuse both.
11 new DebugVM tests covering combat-event-ring subscription, toast
ring cap, diagnostic-flag toggles. UI.Abstractions.Tests: 96 -> 107.
Solution total: 989 green (243 Core.Net + 639 Core + 107 UI).
