Unity Raycasting 2D with Ray

I want to cast a simple Ray, but if I put my Ray I want to cast in the Raycast-function Unity keeps insisting on a Vector2 for the origin instead of accepting origin and direction of the ray. So to demonstrate in code:

void Start()
{
    RayUp = new Ray2D(transform.position, Vector2.up);
}


void Update()
{
    Physics2D.Raycast(RayUp, out WallUp, distance, WallFilter);
    Debug.DrawRay(RayUp);
}

Am I missing anything? WallUp, distance and WallFilter are defined

You are not providing the correct inputs for Debug.DrawRay() and Raycast(). Please take a look at the DrawRay documentation and Raycast() documentation. At a minimum you can do:

Physics2D.Raycast(transform.position, Vector2.up); Debug.DrawRay(transform.position, Vector2.up);

If you want to maintain consistancy from your original RayUp variable you can do:

Physics2D.Raycast(RayUp.origin, RayUp.direction); Debug.DrawRay(RayUp.origin, RayUp.direction);
