Transform.localRotation

Description

相对于父级变换旋转的变换旋转。

Unity stores rotations as Quaternions internally. To rotate an object, use Transform.Rotate. Use Transform.localEulerAngles for modifying the rotation as euler angles.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Example()
    {
        transform.localRotation = Quaternion.identity;
    }
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

// Rotate a cylinder around the x and z axes. Switch from one to the other
// when the rotation in the current axis reaches 360 degrees.

public class ExampleScript : MonoBehaviour
{
    private float x;
    private float z;
    private bool rotateX;
    private float rotationSpeed;

    void Start()
    {
        x = 0.0f;
        z = 0.0f;
        rotateX = true;
        rotationSpeed = 75.0f;
    }

    void FixedUpdate()
    {
        if (rotateX == true)
        {
            x += Time.deltaTime * rotationSpeed;

            if (x > 360.0f)
            {
                x = 0.0f;
                rotateX = false;
            }
        }
        else
        {
            z += Time.deltaTime * rotationSpeed;

            if (z > 360.0f)
            {
                z = 0.0f;
                rotateX = true;
            }
        }

        transform.localRotation = Quaternion.Euler(x, 0, z);
    }
}
