# Vector2::operator==
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
bool operator==(const Vector2& other) const
|
||
|
|
```
|
||
|
|
|
||
|
|
判断两个向量是否相等。使用 EPSILON 进行浮点比较。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `other` - 要比较的向量
|
||
|
|
|
||
|
|
**返回：** `bool` - 如果所有分量差的绝对值都小于 EPSILON 则返回 true
|
||
|
|
|
||
|
|
**线程安全：** ✅
|
||
|
|
|
||
|
|
**复杂度：** O(1)
|

|
|

|
|
**示例：**
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
Vector2 a(1.0f, 2.0f);
|
||
|
|
Vector2 b(1.0f, 2.0f);
|
||
|
|
bool equal = (a == b); // true
|
||
|
|
```
