# Vector3::operator==
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
bool operator==(const Vector3& other) const
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
判断两个向量是否相等。使用 EPSILON 进行浮点数比较。
|
|||
|
|
|
|||
|
|
**参数：**
|
|||
|
|
- `other` - 要比较的向量
|
|||
|
|
|
|||
|
|
**返回：** `bool` - 如果两个向量相等返回 true，否则返回 false
|
|||
|
|
|
|||
|
|
**线程安全：** ✅
|
|||
|
|
|
|||
|
|
**复杂度：** O(1)
|
|||
|
|
|

|
|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
Vector3 a(1.0f, 2.0f, 3.0f);
|
|||
|
|
Vector3 b(1.0f, 2.0f, 3.0f);
|
|||
|
|
Vector3 c(1.0f, 2.0f, 3.00001f);
|
|||
|
|
|
|||
|
|
bool equal1 = (a == b); // true
|
|||
|
|
bool equal2 = (a == c); // true（因为差异在 EPSILON 内）
|
|||
|
|
```
