Question

private static Vector2 DefaultMulFactors = new Vector2(0.5f, 0.5f);
private static Point DefaultShifts = new Point(0,0);

public static Vector2 Function(Vector2? mulFactors = MyClass.DefaultMulFactors , Point? shifts = MyClass.DefaultShifts  )
{ 
    ...
    return result;
}

Why does my code not accept my static values? How can I assign default parameters to my function parameters? Indeed Vector2? mulFactors = new Vector(0.2,0.3) or Vector2? mulFactors = Vector2.Zero does not work.

Answer 1

You can’t, basically. The value must be supported by the compiler to allow that type of usage (it is essentially a constant). I would just use null here:

, Point? shifts = null)

then:

if(shifts == null) shifts = MyClass.DefaultShifts;
