# Vector2::operator+=
|
|
|
|
```cpp
|
|
Vector2& operator+=(const Vector2& other)
|
|
```
|
|
|
|
向量加法赋值，将 `other` 的分量加到当前向量。
|
|
|
|
**参数：**
|
|
- `other` - 要加的向量
|
|
|
|
**返回：** `Vector2&` - 引用到修改后的当前向量
|
|
|
|
**线程安全：** ✅
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
Vector2 v(1.0f, 2.0f);
|
|
v += Vector2(3.0f, 4.0f); // v = (4.0f, 6.0f)
|
|
```
