class UGizmoAxisTranslationParameterSource : public UGizmoBaseFloatParameterSource

Remarks

Various 1D and 2D ParameterSource converters intended to be used to create 3D transformation gizmos. Based on base classes in ParameterSourcesFloat.h and ParameterSourcesVec2.hUGizmoAxisTranslationParameterSource is an IGizmoFloatParameterSource implementation that interprets the float value as the parameter of a line equation, and maps this parameter to a 3D translation along a line with origin/direction given by an IGizmoAxisSource . This translation is applied to an IGizmoTransformSource .

This ParameterSource is intended to be used to create 3D Axis Translation 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.
