# Vector2::operator*
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector2 operator*(float scalar) const
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `scalar` - 标量值
|
||
|
|
|
||
|
|
**返回：** `Vector2` - 缩放后的向量
|
||
|
|
|
||
|
|
**线程安全：** ✅
|

|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector2 v(2.0f, 3.0f);
|
||
|
|
Vector2 scaled = v * 2.0f; // (4.0f, 6.0f)
|
||
|
|
```
