# Vector2::operator-
|
|
|
|
```cpp
|
|
Vector2 operator-(const Vector2& other) const
|
|
```
|
|
|
|
向量减法，将当前向量减去另一个向量。
|
|
|
|
**参数：**
|
|
- `other` - 要减去的向量
|
|
|
|
**返回：** `Vector2` - 相减结果向量
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
Vector2 a(5.0f, 8.0f);
|
|
Vector2 b(2.0f, 3.0f);
|
|
Vector2 c = a - b; // (3.0f, 5.0f)
|
|
```
