Transform.rotation

描述

世界空间中的旋转变换，以 Quaternion 形式存储。

Unity 在内部将旋转存储为四元数。要旋转对象，请使用 Transform.Rotate。 要将旋转设置为欧拉角，请使用 Transform.eulerAngles。Transform.rotation 将提供或接受使用 Quaternion 的旋转。

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);
    }
}
