Method Cross

Cross(Vector2, Vector2)

Computes the cross product of two 2D vectors as v1.x * v2.y - v1.y * v2.x.

Declaration

public static float Cross(Vector2 v1, Vector2 v2)

Parameters

Type	Name	Description
Vector2	v1	First vector.
Vector2	v2	Second vector.

Returns

Type	Description
float	The 2D cross product.

Remarks

This is equivalent to promoting the operands to 3D vectors by setting their Z coordinates to 0, computing their 3D cross product, then returning the Z coordinate of the result. Equals |v1||v2|sin(theta). If v1 and v2 are unit vectors, returns the signed sine of their angle. Returns a positive value if the smallest rotation bringing v1 to v2 is counter-clockwise.
