class UGoogleVRGazeReticleComponent :
public USceneComponent,
public IGoogleVRPointer

Remarks

GoogleVRGazeReticleComponent is a customizable reticle used to interact with actors and widgets by looking at them. Intended for use with Google Cardboard appliations.

This class integrates with GoogleVRPointerInputComponent so that the reticle can easily be used to interact with Actors and widgets.

Variables

	Name	Description
UMaterialInterf...	Material	Material used for the reticle.
UStaticMesh ...	Mesh	Mesh used for the reticle.
bool	RequireInputComponent	If true, then a GoogleVRInputComponent will automatically be created if one doesn't already exist.
float	ReticleDistanceMax	Maximum distance of the reticle (in meters).
float	ReticleDistanceMin	Minimum distance of the reticle (in meters).
float	ReticleGrowAngle	Angle at which to expand the reticle when intersecting with an object (in degrees).
float	ReticleGrowSpeed	Growth speed multiplier for the reticle when it is expanding & contracting.
float	ReticleInnerAngleMin	Minimum inner angle of the reticle (in degrees).
float	ReticleOuterAngleMin	Minimum outer angle of the reticle (in degrees).
