Syntax
class UGizmoAxisScaleParameterSource : public UGizmoBaseFloatParameterSource
Remarks
UGizmoAxisScaleParameterSource is an IGizmoFloatParameterSource implementation that interprets the float value as the parameter of a line equation, and maps this parameter to a scale factor along a line with origin/direction given by an IGizmoAxisSource. This scale is applied to an IGizmoTransformSource.
This ParameterSource is intended to be used to create 3D Axis Scale Gizmos.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
TScriptInterface< IGizmoAxisSource > | AxisSource | The Parameter line-equation value is converted to a 3D Translation along this Axis |
 |
bool | bClampToZero | If true, the minimal output scale will be zero. |
 |
FVector | CurScaleAxis | Scale axis for current parameter edit (only valid between BeginModify/EndModify) |
 |
FVector | CurScaleOrigin | Scale 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) |
 |
float | Parameter | Parameter is the line-equation parameter that this FloatParameterSource provides |
 |
float | ScaleMultiplier | Coordinate delta is multiplied by this amount |
 |
TScriptInterface< IGizmoTransformSource > | TransformSource | This TransformSource is updated by applying the constructed 3D rotation |
