# Vector3::operator[]
|
||
|
||
```cpp
|
||
float operator[](int index) const
|
||
float& operator[](int index)
|
||
```
|
||
|
||
通过索引访问向量的分量。0 = x, 1 = y, 2 = z。
|
||
|
||
**参数：**
|
||
- `index` - 分量索引（0、1 或 2）
|
||
|
||
**返回：** `float` 或 `float&` - 对应分量的值（const 版本返回值，non-const 版本返回引用）
|
||
|
||
**异常：** 如果 index 超出范围（< 0 或 > 2），行为未定义
|
||
|
||
**线程安全：** ✅
|
||
|
||
**复杂度：** O(1)
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
Vector3 v(1.0f, 2.0f, 3.0f);
|
||
|
||
float x = v[0]; // 1.0f
|
||
float y = v[1]; // 2.0f
|
||
float z = v[2]; // 3.0f
|
||
|
||
v[0] = 10.0f; // v = (10.0f, 2.0f, 3.0f)
|
||
```
