# Vector2::Cross
|
|
|
|
```cpp
|
|
static float Cross(const Vector2& a, const Vector2& b)
|
|
```
|
|
|
|
计算两个 2D 向量的叉积（返回标量）。结果为正值表示 b 在 a 的逆时针方向。
|
|
|
|
**参数：**
|
|
- `a` - 第一个向量
|
|
- `b` - 第二个向量
|
|
|
|
**返回：** `float` - 叉积结果 a.x * b.y - a.y * b.x
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
Vector2 a(1.0f, 0.0f);
|
|
Vector2 b(0.0f, 1.0f);
|
|
float cross = Vector2::Cross(a, b); // 1.0f (逆时针)
|
|
```
