Vector3::operator[]
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:
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)
