trying to make a projectile move towards mouse position but but im getting an error anyone able to help

Assets\Scripts\PlayerProjectile.cs(18,38): error CS7036: There is no argument given that corresponds to the required formal parameter ‘maxDistanceDelta’ of 'Vector2.MoveTowards(Vector2, Vector2, float)

so thats the error i get and idk why MoveTowards is under lined with red also this is a 2D game if you couldnt already tell by the vector2 any help would be nice

First off, you should set target in Update, not in Start, because the mouse position is constantly changing.

Second, you have to re-write

transform.position = Vector2.MoveTowards(transform.position, speed * Time.deltaTime);


transform.position = Vector2.MoveTowards(transform.position, target, speed * Time.deltaTime);
