public static [Vector2](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector2.html) **operator *** ([Vector2](https://docs.unity3d.com/cn/2019.4/ScriptReference/Vector2.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/。

```
using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // make the vector twice longer: prints (2.0,4.0)
        print(new Vector2(1, 2) * 2.0f);
    }
}
```
