UGizmoAxisRotationParameterSource

[UGizmoAxisRotationParameterSource](API\Runtime\InteractiveToolsFramework\BaseGizmos\UGizmoAxisRotati-) is an [IGizmoFloatParameterSource](API\Runtime\InteractiveToolsFramework\BaseGizmos\IGizmoFloatParameterSource) implementation that interprets the float parameter as an angle, and maps this angle to a 3D rotation around an [IGizmoAxisSource](API\Runtime\InteractiveToolsFramework\BaseGizmos\IGizmoAxisSource) (ie 3D axis).

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.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
