Just as you can access the "velocity" member of your sprite using the member-of operator '.', you can use it to access the X and Y coordinate values of your Vector2. spr.velocity.X will give you the X coordinate, and spr.velocity.Y will give you the Y coordinate.

spr.destinationRect = new Rectangle(spr.velocity.X, spr.velocity.Y, spr.spriteWidth, spr.spriteHeight);

Hi, Thanks for replying, I'm not very good at explaining code yet, But I guess I mean.
I need to be able to write a Vector2 like this:

u see I've save a velocity like this

    
            spr.velocity = new Vector2((float)Math.Cos(spr.rotation), (float)Math.Sin(spr.rotation)) * 2;

I move my_player like this "spr.my_pos += spr.velocity;" using Vectors
But i need to read it like this

    
            spr.destinationRect = new Rectangle(spr.my_x, spr.my_y, spr.spriteWidth, spr.spriteHeight);

Without using vectors
Id rather replace "spr.my_x, spr.my_y" with the my_pos vecotor but I dont know how to do that.
so atm I'm tring to save the first value of my_pos vector to my_x and the second valuse to my_y.

Or did I just make my problem even more confusing? 0.o

vector2 my_pos = new vector2(64,93)

means

my_pos.X is equal to 64

and

my_pos.Y is equal to 93

if it were a vector3, the third would be the "X, Y, & Z" value,
and a vector 4 would be the "X, Y, Z, & W"

How do I get values 1 and 2 of a Vector2
and use them as follows
this is my my_pos Vector (64,64)

how do i do this?
my_x = my_pos.value1;
my_y = my_pos.value2;

Hope u understand my question any help would be great n_n
