CHANGELOG ​

v1.0.2 ​

26/09/2026

  • Major Feature: Life Editor Debugger for FlowPilot.

  • Update: New Doc site with new guides

  • Add: Editor Debugger. Pick a running instance (Debug Target), see each Task's live state (Running, Succeeded, Failed, Skipped) in the Tree View.

  • Add: Breakpoints on Tasks (F9 or click the row gutter). Play In Editor pauses when the Task starts, and the asset editor opens on it.

  • Add: Step (F10) to the next Task, Resume (F5), Pause and Stop from the FlowPilot editor toolbar and debug bar.

  • Add: Drag and drop Tasks from the Tasks Palette into the Tree View (before, after or into a Task, or onto empty space to add to the Root).

  • Add: In-Game Debug dropdown in the Level Editor toolbar and FlowPilot editor toolbar, to toggle the overlay and pick the FlowPilotComponent to display.

  • Add: Tree View toolbar (Add Task picker, Remove, Enable, Disable, Expand/Collapse All), richer context menu, F2 rename, double click to expand/rename, empty Flow hint.

  • Add: Tasks Palette search by display name, sorted categories with counts, Task icons, double click to add.

  • Update: New, pasted and duplicated Tasks go next to the selection (into a selected parent, after a selected Task) and are selected.

  • Update: Changing a Task class is undoable, keeps the name and the children when switching between parent Tasks (e.g: Sequence to Selector).

  • Update: In-game debug draws Loop and Sub Flow children, shows disabled Tasks, flow name/state in the components list and a message when the index is invalid.

  • Fix: Loop crashed (check) on its second iteration, and returned Error instead of Failed when its Task failed.

  • Fix: Sub Flow crashed when restarted (Reset after Exit), and dereferenced a null instance in Enter.

  • Fix: Play Sound / Play Sound 2D never reported as started (missing Super::Enter).

  • Fix: Actor cache kept growing when several Actors shared a GameplayTag, and skipped entries when removing stale ones.

  • Fix: Debug draw delegate leaked on every World (each PIE session).

  • Fix: Pasting Tasks could replace existing Tasks with the same name, and left orphan objects in the asset.

v1.0.1 ​

22/09/2026

  • Fix: Couple of crashes
  • Add: Couple of tests
  • Add: Support for Unreal Engine 5.8
  • Add: Re-writes BP FadeScreen in Cpp.
  • Add: New Tasks: SetFocus, ClearFocus, MoveTo, RunBehavior AI tasks
  • Add: Viewport on Actor with FlowPilot Selected debug view

v0.9.3 ​

21/09/2024

Breaking change:

Unimplemented Tick tasks no longer automatically succeed, allowing FlowPilotComponent to continue execution. FinishTask has to be called for the task to complete, or implement Tick and return manually.

  • Feature: Allows changing ticking group in Project Settings.
  • Add: Modal to confirm task deletion
  • Add: Automatic Documentation export to FlowPilot.dev
  • Add: Flow Pilot asset can be created from the Content Browser via the Gameplay Menu
  • Add: New Option to spawn Class at a specific world location/rotation
  • Fix: Rare crash when Task was selected without Outer Class.
  • Fix: Crash on Demo Map when you don't have a class to spawn, but still play the game. Gracefully Log and Exit instead of crash.
  • Fix: Parallel Task was not respecting disabled nodes.
  • Update: Set default spawn lifetime to persistent
  • Update: Move Defines to FlowPilotGlobals.h
  • Update: Remove Root Task and Children from details view. No longer needed as the Tree view works correctly.
  • Update: Demo Maps and basic TP Character to remove Dependencies.
  • Update: Default Root node is named after data asset now upon creation
  • Update: Change Delegates to dynamic multicast to allow subscribing via BP
  • Update: Simplify finishing of ongoing tasks by calling FinishTask.
  • Update: Rename UFPTask_FlowActorAsset to UFPTask_SubFlow to make it more akin to a group of FlowTasks. (aka SubTree)
  • Update: Remove UFPTaskRunner. Simplified method calls so that most of it is handled via UFPTask_Sequencer. UFPTask_Selector now inherits from UFPTask_Sequencer and swaps Success/Fail behavior

v0.9.2 ​

24/08/2024

  • Add: New FPTask_PossessPawn, allowing pawn possession by Players or AI
  • Add: New FPTask_PlayAnimation. Similar to BTTask_PlayAnimation, but can play animation on multiple Pawns, and has Soft Pointer to Anim Asset.
  • Fix: Spawning new Classes at runtime with existing cached Tags will properly cache them as well.
  • Fix: Crash when pasting Task form one FlowPilotAsset to another
  • Fix: Some undo functionality has been restored

  • Add: Data Versioning to automatically convert MainFlow to Sequence Child Tasks
