Syntax
class UGizmoTransformChangeStateTarget :
public UObject,
public IGizmoStateTarget
Remarks
UGizmoTransformChangeStateTarget is an implementation of IGizmoStateTarget that emits an FComponentWorldTransformChange on a target USceneComponent. This StateTarget also opens/closes an undo transaction via GizmoManager.
The DependentChangeSources and ExternalDependentChangeSources lists allow additional FChange objects to be inserted into the transaction, provided by IToolCommandChangeSource implementations.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
FText | ChangeDescription | Localized text description of the transaction (will be visible in Editor on undo/redo) |
 |
TArray< TUniquePtr< IToolCommandChangeSource > > | DependentChangeSources | Dependent-change generators. |
 |
TArray< IToolCommandChangeSource * > | ExternalDependentChangeSources | Dependent-change generators that are not owned by this class, otherwise handled identically to DependentChangeSources |
 |
FTransform | FinalTransform | End Transform, saved on EndUpdate() |
 |
FTransform | InitialTransform | Start Transform, saved on BeginUpdate() |
 |
TWeakObjectPtr< USceneComponent > | TargetComponent | The object that will be changed, ie have Modify() called on it on BeginUpdate() |
 |
TScriptInterface< IToolContextTransactionProvider > | TransactionManager | Pointer to the GizmoManager or ToolManager that is used to open/close the transaction |
