# Vector3::operator-
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 operator-(const Vector3& other) const
|
||
|
|
```
|
||
|
|
|
||
|
|

|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `other` - 要减的向量
|
||
|
|
|
||
|
|
**返回：** `Vector3` - 相减结果
|
||
|
|
|

|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector3 a(5.0f, 7.0f, 9.0f);
|
||
|
|
Vector3 b(1.0f, 2.0f, 3.0f);
|
||
|
|
Vector3 c = a - b; // (4.0f, 5.0f, 6.0f)
|
||
|
|
```
