Fix 30+ broken cross-references in docs/api/math/: - viewport: viewport-getaspectratio/getrect -> getaspectratio/getrect - matrix4: ../color/operator-mul -> operator_mul, operator-index -> operator_index - matrix4/get-*: gettranslation/getscale/getrotation -> get-translation/-scale/-rotation - vector3 operator links: operator_*_assign -> operator-*-assign - vector3 operator links: operator_sub/add -> operator-sub/add - vector3 operator-eq/neq: swap mutual references to use hyphen naming - vector4: ../plane/constructor-default -> constructor_default - Linter fixes: aabb and rectint relative paths corrected

# Vector3::operator-=
|
|
|
|
```cpp
|
|
Vector3& operator-=(const Vector3& other)
|
|
```
|
|
|
|
向量减法赋值，从当前向量减去 `other` 的分量。
|
|
|
|
**参数：**
|
|
- `other` - 要减的向量
|
|
|
|
**返回：** `Vector3&` - 引用到修改后的当前向量
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
Vector3 v(5.0f, 7.0f, 9.0f);
|
|
v -= Vector3(1.0f, 2.0f, 3.0f); // v = (4.0f, 5.0f, 6.0f)
|
|
```
