# Vector4::operator==
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
bool operator==(const Vector4& other) const
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
判断两个向量是否相等。
|
|||
|
|
|
|||
|
|
**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，否则返回 false
|
|||
|
|
|
|||
|
|
**示例：**
|
|||
|
|
|
|||
|
|
```cpp
|
|||
|
|
Vector4 a(1.0f, 2.0f, 3.0f, 4.0f);
|
|||
|
|
Vector4 b(1.0f, 2.0f, 3.0f, 4.0f);
|
|||
|
|
bool eq = (a == b); // true
|
|||
|
|
```
