Syntax
class UGizmoAxisRotationParameterSource : public UGizmoBaseFloatParameterSource
Remarks
UGizmoAxisRotationParameterSource is an IGizmoFloatParameterSource implementation that interprets the float parameter as an angle, and maps this angle to a 3D rotation around an IGizmoAxisSource (ie 3D axis). This rotation is applied to an IGizmoTransformSource. This ParameterSource is intended to be used to create 3D Rotation Gizmos.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
float | Angle | Angle is the parameter that this FloatParameterSource provides |
 |
TUniqueFunction< bool(double AngleDelta, double &SnappedAngleDelta)> | AngleDeltaConstraintFunction | Optional axis-delta-angle constraint function. |
 |
TScriptInterface< IGizmoAxisSource > | AxisSource | Float-parameter Angle is mapped to a 3D Rotation around this Axis |
 |
FVector | CurRotationAxis | Rotation axis for current parameter edit (only valid between BeginModify/EndModify) |
 |
FVector | CurRotationOrigin | Rotation origin for current parameter edit (only valid between BeginModify/EndModify) |
 |
FTransform | InitialTransform | Saved copy of Initial Transform for current parameter edit (only valid between BeginModify/EndModify) |
 |
FGizmoFloatParameterChange | LastChange | Active parameter change (only valid between BeginModify/EndModify) |
 |
TUniqueFunction< FQuat(const FQuat &)> | RotationConstraintFunction | Optional rotation constraint function. |
 |
TScriptInterface< IGizmoTransformSource > | TransformSource | This TransformSource is updated by applying the constructed 3D rotation |
