Why won't this loop normalize my Vector2 list?
- by ssb
See the following code:
List<Vector2> axes = new List<Vector2>();
axes.Add(TopRight() - TopLeft());
axes.Add(BottomLeft() - TopLeft());
axes.Add(otherRectangle.TopRight() - otherRectangle.TopLeft());
axes.Add(otherRectangle.BottomLeft() - otherRectangle.TopLeft());
// Try normalizing vectors?
foreach (Vector2 axis in axes)
{
axis.Normalize();
}
the Vector2.Normalize() method is a void method that normalizes the vector it's called on. Yet for some reason when I do this loop it doesn't normalize the vectors. Am I just unable to modify a list this way?
Some oddities:
Iterating with a for loop, i.e. axis[i].Normalize() doesn't work.
Iterating with the built-in List<T>.ForEach iterator does not work.
Creating a normalizing the vector before adding it to the list rather than iterating over the list does work.
Why does iteration not work?
