Quaternion.operator *

参数

描述

将旋转 lhs 和 rhs 组合到一起。

Rotating by the product lhs * rhs is the same as applying the two rotations in sequence: lhs first and then rhs, relative to the reference frame resulting from lhs rotation. Note that this means rotations are not commutative, so lhs * rhs does not give the same rotation as rhs * lhs.

using UnityEngine;
using System.Collections;

public class Example2 : MonoBehaviour
{
    float rotateSpeed = 90;

    // Applies a rotation of 90 degrees per second around the Y axis
    void Update()
    {
        float angle = rotateSpeed * Time.deltaTime;
        transform.rotation *= Quaternion.AngleAxis(angle, Vector3.up);
    }
}

描述

对点 point 应用旋转 /rotation/。

using UnityEngine;
using System.Collections;

public class Example2 : MonoBehaviour
{
    private void Start()
    {
        //Creates an array of three points forming a triangle
        Vector3[] points = new Vector3[]
        {
            new Vector3(-1, -1, 0),
            new Vector3(1, -1, 0),
            new Vector3(0, 1, 0)
        };

        //Creates a Quaternion rotation of 5 degrees around the Z axis
        Quaternion rotation = Quaternion.AngleAxis(5, Vector3.forward);

        //Loop through the array of Vector3s and apply the rotation
        for (int n = 0; n < points.Length; n++)
        {
            Vector3 rotatedPoint = rotation * points[n];
            //Output the new rotation values
            Debug.Log("Point " + n + " rotated: " + rotatedPoint);
        }
    }
}
