Since sel_activa is a value type, not a reference type, when you
"return" it in your "_sel_activa" property, you're returning a value
type, not a reference type, and therefore modifying it would be
worthless, since it wouldn't modify the original.
I'd recommend one of two things:
1) Make Selecction a class instead of a struct.
2) Have a method or property to change "x" instead of trying to access
the sel_activa object directly - for example:
public static void SetSelActivaX(bool newX) {
sel_activa.x = newX;
}
or
public static bool SelActivaX
{ get { return sel_activa.x; } set { sel_activa.x = value; } }
