C# Point structure

Question

Is there a way to store xy cooridnates in a point structure instead of a Vector2 (I dont want to have to convert the floats to int every time I use them)

I tried System.Collections.Generic;, but this still does not give the Point structure for C#. Is there another collections I need to use?

Thanks!

 struct Point
 {
     public int x, y;
 }

then use it like:

 Point myPoint;

 myPoint.x = 5;
 myPoint.y = 3;

you can also use it with a constructor:

 struct Point
 {
     public int x, y;

     public Point(int px, int py)
     {
         x = px;
         y = py;
     }
 }

in which case you could do this:

 Point myPoint = new Point(5, 7);

Thanks! That really helped a lot!! =]!

If you read this, and have a second, I would like to know what exactly is going on. I have not really run into this type of set-up yet in my basic code skills.

Thanks again!!!

Hi, a lot can be said about them so I've provided some links for you. Basically they are very similar to classes, but should generally be used for lightweight things only (unless you want to kill performance). They are a value type like int or char, as opposed to a reference type, which a class is.
