public Quaternion rotation ;

Description

The rotation of the transform in world space stored as a Quaternion.

Unity stores rotations as Quaternions internally. To rotate an object, use Transform.Rotate. Use Transform.eulerAngles for setting the rotation as euler angles. Transform.rotation will provide or accept the rotation using a Quaternion.

In the example below rotation obtains the orientation of the cube. The cube is rotated left-to-right and forward-to-back. Create a project with a single cube at the origin. Attach this script to the cube.

using UnityEngine;

// Tilt the cube using the arrow keys. When the arrow keys are released // the cube will be rotated back to the center using Slerp.

public class ExampleScript : MonoBehaviour { float smooth = 5.0f; float tiltAngle = 60.0f;

void Update() { // Smoothly tilts a transform towards a target rotation. float tiltAroundZ = Input.GetAxis("Horizontal") * tiltAngle; float tiltAroundX = Input.GetAxis("Vertical") * tiltAngle;

Quaternion target = Quaternion.Euler(tiltAroundX, 0, tiltAroundZ);

// Dampen towards the target rotation transform.rotation = Quaternion.Slerp(transform.rotation, target, Time.deltaTime * smooth); } }
