Question

XNA framework for .net has a really useful Object called vector2 that represents a 2d vector..You can multiply them by ints, floats and other Vector 2s

Eg.

        Vector2 bloo = new Vector2(5, 5);
        bloo *= 5;
        bloo *= someotherVector2;

The only thing is that the X,Y information is stored as floats and in a lot of cases I want to simply store 2d info, or 2d coordinates as ints.
I’d like to make my own struct for this..
Heres what i have..

internal struct Coord
{
    public int X { get; private set; }
    public int Y { get; private set; }

    public Coord(int x,int y)
    {
        X = x;
        Y = y;
    }
} 

My question is how do I make it so my Coord struct can be multipled by ints or other Coords using * (Not a “Multiply” function call)

Answer 1

You can use operator overloading:

public static Coord operator*(Coord left, int right) 
{
    return new Coord(left.X * right, left.Y * right);
}

Just put the method into the Coord struct. You can do this with many operators like +,-,/ etc… and also with different parameters.
