UMultiTransformer

[UMultiTransformer](API\Plugins\ModelingComponents\Transforms\UMultiTransformer) abstracts both a default TRS Gizmo, and the "Quick" translate/rotate Gizmos.

Syntax

UCLASS ()  
class UMultiTransformer : public UObject

Remarks

UMultiTransformer abstracts both a default TRS Gizmo, and the "Quick" translate/rotate Gizmos. The "Quick" part is not yet implemented, and we might end up phasing out this class.

Variables

  Type Name Description
Protected variable FFrame3d ActiveGizmoFrame  
Protected variable FVector3d ActiveGizmoScale  
Protected variable ETransformGizmoSubElements ActiveGizmoSubElements  
Protected variable EMultiTransformerMode ActiveMode  
Protected variable bool bDisallowNegativeScaling  
Protected variable bool bForceGizmoCoordSystem  
Protected variable bool bInGizmoEdit  
Protected variable bool bRepositionableGizmo  
Protected variable bool bShouldBeVisible  
Protected variable UProperty TObjectPtr< UDragAlignmentMechanic > DragAlignmentMechanic We have to hold on to the mechanic only because the MultiTransformer has the capacity to delete and recreate its gizmo, in which case we'll need to attach the alignment mechanic again.
Protected variable TUniqueFunction< bool()> EnableSnapToWorldGridFunc  
Protected variable EToolContextCoordinateSystem GizmoCoordSystem  
Protected variable UProperty TObjectPtr< UInteractiveGizmoManager > GizmoManager Note: we could have more pivot change delegates, but we don't yet need them, and we might phase out the UMultiTransformer.
Protected variable TFunction< bool()> IsNonUniformScaleAllowed  
Public variable FMultiTransformerEvent OnEndPivotEdit This delegate is fired when a repositioning drag is completed
Public variable FMultiTransformerEvent OnTransformCompleted This delegate is fired when the drag is completed
Public variable FMultiTransformerEvent OnTransformStarted This delegate is fired when a drag is started
Public variable FMultiTransformerEvent OnTransformUpdated This delegate is fired when a drag is updated
Protected variable IToolContextTransactionProvider * TransactionProvider  
Protected variable UProperty TObjectPtr< UCombinedTransformGizmo > TransformGizmo  
Protected variable UProperty TObjectPtr< UTransformProxy > TransformProxy
