Whitespace error in UITextSplineController

[kasai@cadcenter]

Hi,
I'm using UITextSplineController to make Text follow a spline, but I get an error when I type a Whitespace character.
Is it possible to use Whitespace characters? Is there a solution?

Code:

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Hi
It was possible at some point, maybe there were regressions with later Unity versions. Let me check that and will come back to you soon.
Until then, have a nice day

Hi again

Here is the fix: go to Curvy\Controllers\UITextSplineController.cs, then to the following method:

public void ModifyMesh(VertexHelper vertexHelper)

find the for loop in it, and replace it with the following:

Code:

int readingIndex = 0;
for (int letterIndex = 0; letterIndex < Text.text.Length; letterIndex++)
{
  if (Text.text[letterIndex] == ' ')
    continue;

  glyph.LoadTris(verts, readingIndex * 6);
  readingIndex++;
  UpdateGlyph(glyph);
  glyph.Save(vertexHelper);
}

Please let me know if this didn't fix the issue.

If and when you feel like it, please leave a review for the asset, that helps a lot.
Have a nice day

Thank you for your quick response. I can now enter Whitespaces!!
