Syntax

class UEditorInteractiveToolsContext : public UInteractiveToolsContext

Remarks

UEditorInteractiveToolsContext is an extension/adapter of an InteractiveToolsContext designed for use in the UE Editor. Currently this implementation assumes that it is created by a Mode Manager (FEditorModeTools), and that the Mode Manager will call various API functions like Render() and Tick() when necessary.

allows it to be easily embedded inside an FEdMode. A set of functions are provided which can be called from the FEdMode functions of the same name. These will handle the data type conversions and forwarding calls necessary to operate the ToolsContext

Variables

  Type Name Description
Protected variable UGizmoViewContext * GizmoViewContext An object in which we save the current scene view information that gizmos can use on the game thread to figure out how big the gizmo is for hit testing.
Protected variable TMap< FViewportClient *, int32 > InvalidationMap Tools need to be able to Invalidate the view, in case it is not Realtime.
Protected variable int32 InvalidationTimestamp Current invalidation timestamp, incremented by invalidation calls
Public variable FOnDrawHUD OnDrawHUD  
Public variable FOnRender OnRender  
Public variable FOnTick OnTick  
Protected variable TOptional< EToolShutdownType > PendingToolShutdownType  
Protected variable TOptional< FString > PendingToolToStart  
Protected variable IToolsContextQueriesAPI * QueriesAPI EdMode implementation of InteractiveToolFramework APIs - see ToolContextInterfaces.h.
Public variable TObjectPtr< UMaterialInterface > StandardVertexColorMaterial  
Protected variable IToolsContextTransactionsAPI * TransactionAPI
