- Implies that parameters are only set once at start
- Allows parameters to be safely mutated if needed, e.g. via property references
[CL 30765232 by mikko mononen in ue5-main branch]
- Added FStateTreePropertyRef which allows to get pointer to bindable output properties in the StateTree
- This will eventually supercede FStateTreeStructRef
[CL 30563615 by mikko mononen in ue5-main branch]
- During state selection keep track if the current state we're expanding is part of the active states, if not prevent access to instance data

[CL 30036182 by mikko mononen in ue5-main branch]
- Added LinkedAsset State Tree State Type
- Allow to pick nested tree asset on LinkedAsset states
- Changed how linked state params are accessed using ParentFrame
- Added temporary instance data
- Temporaries are kept around until state selection
- Create temp instance data during state selection for state parameters (allows to create enter conditions based on subtree state params)
- Instantiate and Start linked State Trees global tasks and evaluators during state selection
- Matching temporary instances created during state selection are moved to instance data on state change (rest are discarded)
- Per node instance data is looked up just once, and FStateTreeExecutionContext::GetInstanceData() only serves the specific instance data.

[CL 30012308 by mikko mononen in ue5-main branch]
- Remove DataView concept
- Added FStateTreeExecutionFrame, which defines an active branch of a specific state tree that is running
- Added FStateTreeDataHandle, which allows frame relative access of instance data (replaces the DataViews)
- Changed linked states to spawn new frames (will later extend to handle linked trees on other assets)
- Bumped StateTree data version number, requires recomplation of StateTrees

StateTree: Changed how instance data is accessed

- Added FStateTreeExecutionFrame, which defines an active branch of a specific state tree that is running
- Added FStateTreeDataHandle, which allows frame relative access of instance data (replaces the DataViews)
- Changed linked states to spawn new frames (will later extend to handle linked trees on other assets)
- Bumped StateTree data version number, requires recomplation of StateTrees

Added "Next Selectable State" transition option which is similar to "Next State" but the difference is that if the next state fails to be selected (i.e. enter condition failed), then instead of going back up the hierarchy, it will try to select the next sibling until it finds one that is selectable or if it reached the end of the sibling list.

[CL 28852004 by juan portillo in ue5-main branch]
- replaced node details view by embedding property values in the tree view
- node exported text (e.g. Task, Conditions, etc) is no longer imported in struct or object to avoid problems with missing types or property types with specific requirements (e.g. Object base property needs to find the specified value). Goal is to always be able to inspect key/value pairs.
- improved hierarchy of event to improve readibility
- started adding some custom row widgets for the different event types
- reworked the toolbar to regroup the different concepts (Simulation controls, Trace recording, Trace analyzing)
#rnx
#rb mikko.mononen
[CL 26855639 by yoan stamant in ue5-main branch]
- added option to disable state transitions
- added state transition breakpoints
- fixed scrubbing not using the right time (analysis time instead of world simulation time) when hitting a breakpoint
- fixed new instance auto selection on record when previous selection is a stale subtrack
- added console variable `statetree.displayitemids` to display states, tasks and transitions Ids in the StateTreeEditor (details view and state treeview)
#rb mikko.mononen
[CL 26128077 by yoan stamant in ue5-main branch]
- Allow to specify the completion status and terminal state when calling Stop() on State Tree exection context
- Global task's execution status directly translates to stree state on global EnterState (previously could just fail)
- Report terminal state transitions for global tasks (allows to use same task erro handling on states and global)
- Tie global task exection to the tree status, global tasks get ExitState() when transitioning to terminal state
- RequestTransition() was errorneuously reporting TreeRunStatus (instead of LastTickStatus) in Transition.CurrentRunStatus, this made it impossible to detect failed transitions on ExitState()
#preflight 647dae328b08a8b7939102ab
[CL 25789064 by mikko mononen in ue5-main branch]
- Added trace event for Phase (Push + Pop) to make it easier to recreate the event hierarchy when analyzing the traces.
- Merged enums EStateTreeTraceInstanceEventType and EStateTreeTraceNodeEventType to EStateTreeTraceEventType which is mainly a list of verbs that could be reused for different events (States, Instances, Tasks, etc.)
- EStateTreeUpdatePhase is no longer used as flags and reduced to uint8
- Phase events are stacked when producing traces and sent only if meaningful events (Task, State, Transition, etc.) are sent during their scope. This is to avoid sending useless events when the StateTree is ticked without any changes

[CL 25663847 by yoan stamant in ue5-main branch]
- added traces for transitions
- support for recursive state selection
- fixed breakpoints not stopping execution since timelines were added
- added meta data to types used for event visualization
- forced expansion for all treeview items in frame details

[CL 25582715 by yoan stamant in ue5-main branch]
- moved debugger related files to a dedicated directory
- trace provider now allows to read all timelines associated to a given state tree asset instance
- added multiple slate widgets to manage tracks and timelines (directly inspired from RewindDebugger to make it easier to integrate the tools together eventually).
- added synchronized lists of instance names and timelines
- converted EStateTreeUpdatePhase to enum flags used to build frame details hierarchically
#preflight 645a57584c3ec54e6e65f494
[CL 25390252 by yoan stamant in ue5-main branch]
- replaced log listing by treeview (as a prototype but will be replaced by a timeline)
- added event for conditions
- added details view for Condition and Tasks instance data
#rb mikko.mononen
#preflight 644002eea35280ed4f7a6afe
[CL 25110578 by yoan stamant in ue5-main branch]
- Added selection behavior None (not selectable)
- Added selection behavior TryEnterState (enters the specific state, does not consider child states)
- Added selection behavior TryFollowTransitions (follows transitions when state is tried to be selected)
- Brushed up a bit the state representation in editor (added icons, cleaned up layout)
#preflight 6436843df12d5de705595942
[CL 25005118 by mikko mononen in ue5-main branch]
Initial version of the debugger
- currently compiled by StateTreeModule and StateTreeEditorModule using WITH_STATETREE_DEBUGGER
- currently not exposed to UI by StateTree settings 'bUseDebugger'
- in this version only one instance per asset can be debugged
- using Trace services to read events generated by statetree instances.
- can connect to any traces (Editor, Client, Server) as long as the compiled statetree matches

[CL 23844750 by henrik karlsson in ue5-main branch]
- Added ability for tasks to request transitions
- Added buffered transition requests
- Added callback method to FStateTreeTaskBase which is called during transition triggering
- Allow FStateTreeStateLink to be added to tasks and conditions (resolved automatically during compile)
#jira UE-174250

[CL 23815873 by mikko mononen in ue5-main branch]
- Calling GetStateTreeRunStatus() on unintialized instance is not error anymore, returns failed
- Made UStateTreeComponent::GetStateTreeRunStatus() to return failed instead of unset to be consistent with FStateTreeExecutionContext
- Allow to access execution state directly from instance data without exec context
- Do no crete exec context in UStateTreeComponent when sending events
