# Vector2::Normalize
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
static Vector2 Normalize(const Vector2& v)
|
||
|
|
```
|
||
|
|
|
||
|
|
将向量归一化为单位长度。如果向量长度接近零，返回零向量。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `v` - 要归一化的向量
|
||
|
|
|
||
|
|
**返回：** `Vector2` - 归一化后的单位向量
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|
||
|
|
|
||
|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector2 dir = Vector2::Normalize(Vector2(3.0f, 4.0f)); // (0.6f, 0.8f)
|
||
|
|
```
