Quaternion.eulerAngles
var eulerAngles: Vector3;
Description

Returns the euler angle representation of the rotation.

A rotation that rotates euler.z degrees around the z axis, euler.x degrees around the x axis, and euler.y degrees around the y axis (in that order).
	// Create a rotation
	var rotation = Quaternion.identity;
	// Assign a rotation 30 degrees around the y axis
	rotation.eulerAngles = Vector3(0, 30, 0);
	// print the rotation around the y-axis
	print(rotation.eulerAngles.y);
