Detailed Description

Converts a BehaviorTreeAsset into an Olympe::NodeGraph for display in the NodeGraphPanel (Blueprint Editor pipeline).

The resulting NodeGraph preserves the original BT node IDs so that NodeGraphPanel::SetActiveDebugNode() works directly with BT node indices.

FromBehaviorTree()

NodeGraph * Olympe::NodeGraphShared::BTGraphDocumentConverter::FromBehaviorTree ( const BehaviorTreeAsset *  tree )

static

Converts a BehaviorTreeAsset into a heap-allocated NodeGraph.

Two-priority loading strategy:

1. JSON source file (preferred): queries BehaviorTreeManager::GetTreePathFromId() to obtain the asset path, then calls NodeGraphManager::LoadGraph() to parse the file. This preserves the visual positions saved in the JSON, making the debugger layout identical to the Blueprint Editor standalone view. ClearDirty() is called on the resulting graph because the debugger is read-only. The temporary graph slot in NodeGraphManager is closed immediately after cloning.
2. BFS fallback: used when the path is unknown (prefixed "TreeName:") or when LoadGraph returns -1. Positions are computed by BTGraphLayoutEngine.

Parameters

tree	BehaviorTree asset to convert (non-null).

Returns

Newly allocated NodeGraph (caller takes ownership). Returns nullptr if tree is null.

SyncActiveNode()

void Olympe::NodeGraphShared::BTGraphDocumentConverter::SyncActiveNode ( NodeGraph *  graph, uint32_t  currentNodeId  )

static

Synchronises the active-node metadata in an existing NodeGraph.

No-op for the NodeGraph model; actual highlight is driven by NodeGraphPanel::SetActiveDebugNode(). Kept for API symmetry.

Parameters

graph	Target graph (may be null — safely ignored).
currentNodeId	BT node currently executing.
