Get Lines of a UI text

Question

Hi all,

How can I get the lines of Text that is showing in the game, not in the inspector window, as u see in the picture:

alt text

 myText = GetComponent<Text>();    
 string[] lines = myText.text.Split('\n');
 try{print(lines[0]);}catch{}
 try{print(lines[1]);}catch{}
     
  //real output :
  //New Text
  //What I expect:
  //New
  //Text

Text.cachedTextGenerator has the info you need. It won't show correct line splitting until the next frame, but you can force it to update early by calling Canvas.ForceUpdateCanvases().

 myText.text = "this is a very extremely super duper incredibly unbelievably very long sentence";
 Canvas.ForceUpdateCanvases();
 for (int i = 0; i < myText.cachedTextGenerator.lines.Count; i++) {
     int startIndex = myText.cachedTextGenerator.lines[i].startCharIdx;
     int endIndex = (i == myText.cachedTextGenerator.lines.Count - 1) ? myText.text.Length 
         : myText.cachedTextGenerator.lines[i + 1].startCharIdx;
     int length = endIndex - startIndex;
     Debug.Log(myText.text.Substring(startIndex, length));
 }

Thank you very much! The way you get the endIndex is so clever! (And t?x:y conditional operator is so usefull!)

Revisiting this with TextMeshPro, use TextMeshProUGUI.ForceMeshUpdate(true, true) instead of Canvas.ForceUpdateCanvases(), then TextMeshProUGUI.textInfo to fetch line info.

text = myText.GetComponent(); lines = text.cachedTextGenerator.lineCount;

You need to first get the GameObject that it is associated with. Then you need to get the text component of it. Then once you have the Text component, you can use .text to get/set the text.

To get the Gameobject, you can do something like GameObject.Find(); //can take in a tag or game object name.

Then a .GetComponent(); to get the text component

Then .text.

     // You also need the correct imports, think it's only these two.  
     // Might have a  text one too, cant remember.  You can figure that out
     using UnityEngine;
     using UnityEngine.UI;
 
     GameObject textGO = GameObject.Find("Text");
     Text textInfo = textGO.GetComponent<Text>();
     string[] lines = textInfo.text.Split('\n');
     try{print(lines[0]);}catch{}
     try{print(lines[1]);}catch{}

This is actually attached to the text object, and the "myText" is the Text component that is attached to the gameobject. my problem is the myText.text returns the value that has been entered in the inspector, but I want what player see in the game window.

I will edit my code in first post.

anyway thanks for the reply

ohhh I see your problem... haha, that's funny. So the text field is "New Text" as said in the inspector. The split isn't working because the text is "New Text". The reason the text on the screen is different is because the text box isn't big enough to support the string "New Text" on one line so it wraps it. There is no '\n'

You could split it on ' ' (space) ins$$anonymous$$d but I don't think that is what you want?

 string[] lines = myText.text.Split(' ');

Will give you:

New

Text

No , that's not what I want, I need more general solution.

There must be a way to see how many characters can a line hold in UI/Text, then we can split the words and count the length of every word and see by adding which word the line length goes over that maximum length. then we can consider it one line.

but I can't find such a property for UI/Text.

Did you try this? https://assetstore.unity.com/packages/tools/gui/fully-flexible-ui-text-148050 A single UIText is replaced by UITexts, one for each character. In your case, it seems that you need to separate by "\n", the basic idea should be the same.
