# 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)
```
