TMP text word location?

Unity Engine
1

Hello, I am using text mesh pro GUI to get certain words that are shown on screen, but I would like to be able to get the location of those certain words, and cant figure out how too. Also really struggling to find good documentation on this.
I have managed to get the info on what word is clicked, but how do i go about getting its position in the world from there? The code I am using to get the word clicked info is

 if (Input.GetMouseButtonDown(0))
        {
            intwordIndex = TMP_TextUtilities.FindIntersectingWord(textElement, Input.mousePosition, null);      

            Debug.Log(wordIndex);

Because I am struggling to find documentation, I have check all the methods that show when I type in TMP_ class name. However I have not came across anything that I think could do what I am wanting.

There is some helper class to do this in TMPro… I always forget if it is called layout or measurement or positioning. Hang on a sec while I look.

I think it’s something in here? TMP_TextUtilities Check around and see what those do… there definitely is something that lets you find where it all goes…

Thank you, I will take a look at that and hopefully find something useful :slight_smile:

Did you ever end up finding anything? I’m currently trying to acomplish the same thing you were, finding the worldposition of a particular word in a string of text.

This might help anyone looking into this.
The characterInfo array has the position info for individual characters in TMP_Text space, on another hand, you can get each word first and last characters using TMP_WordInfo struct. Putting these together, you can get each word rect info in world space after translating character position using tmp_text.transform.TransformPoint:

foreach (var wordInfo in tmpText.textInfo.wordInfo)
        {
            if (wordInfo.characterCount == 0)
                continue;

            var firstCharInfo = tmpText.textInfo.characterInfo[wordInfo.firstCharacterIndex];
            var lastCharInfo = tmpText.textInfo.characterInfo[wordInfo.lastCharacterIndex];
            var wordLocation = tmpText.transform.TransformPoint((firstCharInfo.topLeft + lastCharInfo.bottomRight) / 2f);
            Instantiate(WordMarker, wordLocation, Quaternion.identity);
        }
