Quaternion.y

Description

Y component of the Quaternion. Don't modify this directly unless you know quaternions inside out.

//Create three Sliders (Create>UI>Slider) and three Text GameObjects (Create>UI>Text). These are for manipulating the x, y, and z values of the Quaternion. The text will act as a label for each Slider, so position them appropriately.
//Attach this script to a GameObject.
//Click on the GameObject and attach each of the Sliders and Texts to the fields in the Inspector.

//This script shows how the numbers placed into the x, y, and z components of a Quaternion effect the GameObject when the w component is left at 1.
//Use the Sliders to see the effects.
