New UWorldSubsystem + FTickableGameObject drives per-property keyframe
animation in both the runtime editor and real gameplay (server-side,
replicated to clients via standard UE property replication). Tightly
coupled with Simulate: Play/Pause/Stop also start/stop AI.
Highlights:
- bAnimatable flag on EditablePropertyEntry gates which properties get
a "+" keyframe button in the runtime editor
- FGuid-based actor IDs in the timeline subsystem survive save/load
- Custom Slate widgets replace SSlider/SButton for pixel-perfect
alignment between the scrub bar handle and keyframe dots
- Click a key = select actor + seek; drag moves it; Del removes it
- Active key highlighted green; selected key white; auto-deselect when
the cursor leaves the key time
- Scenes loaded via the standalone SceneLoader auto-play in gameplay;
SceneSerializer pushes timeline data into the subsystem on load
- SceneData v3 -> v4 (Timeline + per-actor ActorId); legacy scenes
load cleanly with empty timeline + regenerated GUIDs
- "Unfiled" scenes no longer try to load a bogus sublevel (loading
screen no longer gets stuck); LoadBaseLevelAsSublevel now has a
safety net that hides the overlay if LoadLevelInstance fails
- TryLoadClass via FSoftClassPath fixes the intermittent "actors
disappear on first load" bug (BP class cold-load race)

Refactor spline system to use IPS_Editor_SplineEditable interface:
- New interface in Spline/PS_Editor_SplineEditable.h with all editing methods
- APS_Editor_SplineActor and APS_BehaviorEditor_AISpline both implement it
- All ~40 Cast<APS_Editor_SplineActor> replaced with Cast<IPS_Editor_SplineEditable>
- UndoManager SplinePointAction uses TWeakObjectPtr<AActor> + interface cast
- Any actor implementing the interface works with full editor spline editing
Spline visibility:
- SetVisualizationVisible() hides tube/handles/cube in gameplay (data stays for AI)
- SceneLoader calls it when stripping editor components
- SplineMatOccluded material added (unused for now, PP occlusion planned)
Other improvements:
- Snap spline CP to ground on placement (downward raytrace)
- Play button works without BaseLevel (uses current editor map)
- AISpline triggers SplineNetwork::RebuildNetwork on BeginPlay (next tick)
- PS_BehaviorEditor marked EnabledByDefault: false (only active in PROSERVE)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

- Full tube visualization + handles (adapted from PS_Editor_SplineActor)
- SpawnableComponent (catalogue category "AI") + EditableComponent
- Editable AI properties: SplineCategory, bBidirectional, SplineWalkSpeed, Priority
- Custom serialization for spline points + AI properties
- No modifications to PS_Editor or PS_AI_Behavior plugins

Default SBorder brush is semi-transparent in PIE. Using explicit
WhiteBrush (solid 1x1 texture) ensures fully opaque panels everywhere.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Fixes inconsistency between PIE (transparent) and packaged (opaque).
All SBorder BackgroundColor alpha changed from 0.85 to 1.0.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
OpenLevel("test") was resolving to the streamed sublevel instance
(test_LevelInstance_5) instead of the actual map. Fix:
- Unload sublevel via LoadBaseLevelAsSublevel("None") before OpenLevel
- Use full path "/Game/{BaseLevel}" to avoid ambiguity
Also: all widget lambdas now get SpawnManager/SceneSerializer fresh from
PlayerController (critical fix for packaged builds where weak ptrs are null).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Critical fixes for packaged builds:
- Widget weak ptrs (SpawnManager/SceneSerializer) are null in packaged due to
HUD deferred init. All button lambdas now get references fresh from
PlayerController via GetOwningPlayer() cast instead of cached weak ptrs.
- HUD BeginPlay deferred by one tick (SetTimerForNextTick) to ensure
PlayerController has initialized SpawnManager before wiring.
Module split:
- Factories moved to separate PS_EditorTools module (Type: Editor)
to fix UHT error with UFactory in packaging builds.
- PS_Editor module no longer depends on UnrealEd for factories.
Asset references:
- TSoftObjectPtr/TSoftClassPtr changed to TObjectPtr/TSubclassOf for
MasterCatalog, SpawnCatalogs, and ActorClass entries. Hard references
ensure assets are cooked in packaged builds.
Other fixes:
- GetActorLabel() replaced with GetClass()->GetName() (editor-only API)
- Missing brace in Browse dialog BaseLevel sync code
- BaseLevel sync only when scenario specifies a LevelName (no more clearing on empty)
- Save As dialog with native Windows file picker
- Debug info in catalog UI when empty (shows chain: Master→Catalogs→Entries)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- SceneSerializer created before subsystem check (was nullptr crash)
- ComboBox OnSelectionChanged ignores ESelectInfo::Direct (programmatic)
to prevent NativeConstruct from clearing the just-loaded scenario
- SaveNameField restored from LastEditedScenarioName on return
- Added ReturnToEditor/OpenEditor to GameInstanceSubsystem
- EditorMapName auto-saved on Play for return navigation
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Editor workflow:
- Removed auto-detection of BaseLevel (strip _Editor). Editor is standalone.
- User selects BaseLevel from ComboBox (populated from MasterCatalog.BaseLevels)
- "None" option for editing without a base level
- Selecting BaseLevel: clears current scenario, hides persistent level actors,
loads sublevel. Selecting "None" restores persistent level actors.
UI terminology: Scene → Scenario (save field, buttons, notifications)
GameInstanceSubsystem:
- Renamed PendingSceneName → PendingScenarioName
- Added LastEditedScenarioName/LastEditedBaseLevel (persist after Consume)
- SetPendingScenario() stores in both Pending and LastEdited
- ReturnToEditor() restores Pending from LastEdited, opens editor map
- EditorMapName auto-saved on first Play, used by ReturnToEditor
- OpenEditor() / ReturnToEditor() callable from gameplay BP
Play button: resets input mode before OpenLevel (fixes cursor in FirstPerson GM)
Test assets: FirstPerson template for testing Play/ReturnToEditor flow
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Architecture for single editor map workflow:
- MasterCatalog.BaseLevels lists available base levels
- BaseLevel selector in UI (cycle button) loads selected level as sublevel
- Sublevel provides visual context only — save/load only touches PS_Editor objects
- No auto-load at startup: user picks via UI or PROSERVE sets via subsystem
GameInstanceSubsystem (survives OpenLevel):
- PendingSceneName + PendingBaseLevel set by PROSERVE before opening editor
- Editor reads them at BeginPlay: loads sublevel + scene automatically
- ConsumePendingScene() for gameplay side to read and clear
Play button:
- Auto-saves current scene
- Stores scene name in GameInstanceSubsystem
- Opens the BaseLevel via OpenLevel
SceneLoader:
- bStripEditorComponents parameter (default true) removes Spawnable/Editable
components after load for clean gameplay actors
SceneData v3: LevelName field associates scenes with base levels.
Scene list filtered by selected BaseLevel.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
PlayerController gets a BaseLevelNameOverride property. When set (e.g. "Warehouse"),
scenes are tagged with that level name instead of the auto-detected map name.
Use case: editing on "Warehouse_Editor" map but scenes should be associated
with the "Warehouse" base level for PROSERVE runtime loading.
Save, load list, and scene filtering all respect this override.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
SceneData now includes LevelName field (auto-detected from current map on save).
Version bumped to 3. Backward compatible (empty LevelName for old files).
SceneLoader:
- GetSavedSceneNames(LevelFilter) filters by associated level
- GetSceneLevelName() reads level association without full parse
- GetSavedSceneNamesForCurrentLevel() convenience for game code
Editor UI:
- Scene list grouped: "This level" (highlighted) + "Other levels" (dimmed)
- Shows current level name above the list
PROSERVE integration pattern:
// List scenarios for current level
auto Scenes = UPS_Editor_SceneLoader::GetSavedSceneNamesForCurrentLevel(this);
// Load a specific scenario
UPS_Editor_SceneLoader::LoadScene(this, "Scenario_A", OutActors);
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
UPS_Editor_SceneLoader is a BlueprintFunctionLibrary that loads PS_Editor
JSON scenes without any editor infrastructure (no PlayerController, Gizmo,
SelectionManager, or UI required).
Usage from any GameMode:
TArray<AActor*> Actors;
UPS_Editor_SceneLoader::LoadScene(this, "MyScene", Actors);
Handles: class loading (BP + C++), transforms, custom editable properties
via reflection (ImportText), and spline point data. All functions are
BlueprintCallable for BP GameMode usage.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Major UX simplification:
- Removed SplineEditing mode — single SplinePlacement mode handles both
creation and editing with identical behavior
- Actor spawned and tracked on first click (no "finish" step needed)
- Each point add/insert/move has individual undo
- Right-click always = camera fly (no special handling during creation)
- Escape/Done just exits edit mode, nothing to "finish"
Catalog system:
- MasterCatalog DataAsset groups multiple SpawnCatalogs (Tools, Characters, Props)
- PlayerController references one MasterCatalog instead of single catalog
- SpawnManager.AddCatalog() loads sub-catalogs incrementally
- Factory for MasterCatalog creation in Content Browser
Spline polish:
- SplineActor has built-in SpawnableComponent + EditableComponent
- SplineColor/SplineSelectedColor/SplineTag as UPROPERTY for BP variants
- All spline point operations use World coordinate space (fixes snap-to-ground)
- Snap-to-ground ignores gizmo actor (was hitting gizmo guide lines)
- Tube mesh collision forced with UpdateBounds after CreateMeshSection
- Tube insert and handle selection include active placement actor (not just selected)
- Notification bar shows contextual Delete Point button when CP selected
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Architecture:
- New IPS_Editor_PointPlaceable interface for any actor using click-to-place-
points placement. Decouples the placement system from SplineActor so future
actors (patrol routes, area polygons) can reuse the same flow.
- SplineActor implements the interface. BP subclasses with SpawnableComponent
appear in the catalog and automatically enter placement mode when spawned.
- PlayerController methods renamed: BeginPointPlacement/FinishPointPlacement/
CancelPointPlacement (generic, interface-driven).
Features added:
- SplineColor, SplineSelectedColor, SplineTag as UPROPERTY for BP overrides
- UpdateSplineMaterials() for runtime color changes
- Tube visualization (8-segment cylinder) replacing cross-ribbon
- Spline editing mode with Edit/Done buttons in notification bar
- Delete spline point (Del key or Delete Point button, min 2 points)
- Insert point by clicking on tube mesh in edit mode
- Snap spline point to ground (End key)
- Append points to existing spline (S key or catalog when spline selected)
- Notification bar: contextual messages and buttons per mode
- Auto-generated M_PS_Editor_SplineLine material (unlit opaque, depth tested)
- Material swap: opaque when deselected, no-depth-test when selected
- Serialization of SplineColor/SplineTag in CustomProperties
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Spline placement: New Spline button (S key) enters placement mode where clicks
add control points. Right-click/Enter finishes, Escape cancels. Min 2 points.
Spline visualization as cross-shaped quad strip (vertical + horizontal ribbons).
Point editing: select spline to show handles, click a handle to position gizmo
on it, then use translate gizmo to move individual points. Undo supported via
full-state snapshots (SplinePointAction).
Visual feedback: auto-generated M_PS_Editor_SplineLine material (unlit opaque
with depth test) for normal state. Gizmo material (no depth test) for selected
state. Center cube at centroid for whole-spline selection. Handles highlight
on selection.
Serialization: spline points exported to CustomProperties (PointCount + Point_N).
C++ class fallback via FindObject for LoadScene. Spline appears in scene outliner.
Still WIP: depth material swap on selection, serialization edge cases, and
point editing polish to be refined.

Property Editing:
- New EditableComponent with two-step dropdown (Select Component → Add Property)
to declare which properties are exposed in the runtime editor
- Dynamic property panel below Transform: supports float, bool, string, FVector,
FRotator, FLinearColor with per-tick refresh and keyboard focus guard
- PropertyAction undo/redo via ExportText/ImportText reflection
- Custom properties serialized to JSON (TMap in ActorData, version 2)
- Copy/paste/duplicate propagate custom property values
Scene Outliner:
- Scrollable list of spawned actors in the right panel
- Click to select, selected actor highlighted in blue
- Auto-refreshes when actors are added/removed
Selection Filter:
- Only actors spawned by the editor (catalogue, duplicate, paste, load)
are selectable — static scene geometry is no longer clickable
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Duplicate clones selected actors with a small offset and selects the copies.
Copy stores actor class and relative transforms in an internal clipboard.
Paste spawns clipboard contents in front of the camera preserving relative positions.
All operations are tracked by SpawnManager and fully undoable/redoable.
