public static [Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **operator *** ([Vector3](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector3.html) **a**, float **d**);

## 描述

将向量乘以一个数值。

将 `a` 的每个分量乘以数值 /d/。

```
// make the vector twice longer: prints (2.0,4.0,6.0)
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Example()
    {
        print(new Vector3(1.0f, 2.0f, 3.0f) * 2.0f);
    }
}
```
