Textmeshpro Caret Position Change

i'm trying to move caret in textmeshpro inputfeild To A Certain Position In A String of 10 letters
but it is not working for some reason i've used the latest version of textmeshpro

I've logged the position and it is accurate but visually the cursor stays at the same place
can anyone help me on how to move caret in inputeild manually via script

public TMP_InputField MessageInputField;
void SomeFuntion(){
MessageInputField.caretPosition = MessageInputField.text - 5;
}

 

Did you find any solution by now?

I have the same problem with Unity 2018.1.0f2 and TMP 1.2.2 from the package system.
Setting caretPosition does not seem to have any impact on the caret position.

 

Update:
Found this solution to move the cursor to the end of the line: https://forum.unity.com/threads/move-cursor-to-end-of-text.530903/#post-3525370

Still no idea how to move the caret to a position which is neither the start nor the end of the text.
Even when setting carePosition in LateUpdate or delayed with a coroutine it doesn't seem to do anything.

 

I managed to get something like this to work. Although it is a workaround...

I wanted to make another UI item (which is linked to a part of the text) to select the correct piece of text when I hover the other UI item.

Something like this is what I ended up using on that other UI item.

Code (CSharp):

1. public class ExampleClass : Selectable, IPointerEnterHandler, IPointerExitHandler
2. {
3.     [SerializeField]
4.     private TMP_InputField field;
5.  
6.     public override void OnPointerEnter(PointerEventData eventData)
7.     {
8.         field.selectionAnchorPosition = 1; // your caret start position here
9.         field.selectionFocusPosition = 4; // your caret end position here
10.         field.Select();
11.         this.Select();
12.     }
13.  
14.     public override void OnPointerExit(PointerEventData eventData)
15.     {
16.         field.selectionAnchorPosition = field.selectionFocusPosition;
17.         field.Select();
18.         this.Select();
19.     }
20. }

I don't know whether this will work for you because you have a different setup. But when I added the 2 selects, it started to work as intended. So I think this might work for you aswell, provided you have something else to select.

 

The original problem you posted is that you are trying to subtract integer from a string. In most basic case something like this should do the job:

Code (CSharp):

1. // Move caret to the given position
2. void MoveCaretTo(int pos){
3.   inputfield.caretPosition = pos;
4. }

P.S.
There are two attributes:

caretPosition

and

stringPosition

.
caretPosition - represents caret position ignoring rich text tags
stringPosition - represents caret in the original string (tags included)

Personally I've had some issues that after adding some tags, visually caret jumps to other place even if I didn't modify any of these attributes. I've done some debugging and I think that actual caret position that user sees is based on

stringPosition

. I had do modify this attribute so user won't feel the difference and caret will stay in same place because caretPosition is (in my opinion) based on stringPosition. Fun thing is that caretPosition updates only after user modifies input so it is possible to jump into situation that modifying caretPosition does not do anything.

 

It doesn't. Setting the caret doesn't do absolutely nothing.

 

This should be working as I tested it today again.

What version of TMP are you using?

Can you provide the full script you are using to test this?

 

I've run into this too, unable to increment or decrement the caret position. (Used on a world space UI control). TextMesh Pro 1.3.0, Unity 2018.3.1ff

Code (CSharp):

1.  
2.      public TMP_InputField lblReadout;
3.  
4.     //Remove character to the left of the caret
5.      public void Backspace() {
6.             if(lblReadout.caretPosition > 0) {
7.                 lblReadout.text.Remove(lblReadout.caretPosition - 1, 1);
8.             }
9.         }
10.  
11.         //Shift the caret to the left
12.         public void PrevCaretPos() {
13.             if(lblReadout.caretPosition > 0) {
14.                 lblReadout.caretPosition = lblReadout.caretPosition--;
15.             }
16.         }
17.       //Shift the caret to the right
18.         public void NextCaretPos() {
19.             if(lblReadout.caretPosition < lblReadout.text.Length - 1) {
20.                 lblReadout.caretPosition = lblReadout.caretPosition++;
21.             }
22.         }
23.  

 

This is still not working.
Using Unity 2022.1.1f1.

 

'stringPosition' works perfectly. Thanks!

 

Yes, stringPosition works as expected while caretPosition doesn't do anything. I'm not using any rich text tags at all. I even disabled rich text on the input field component.

So I guess for now simply using stringPosition is the best (or only?) way to make it work. Even if you aren't using rich text.

 

interesting.. so many weird issues in a project I have with text caret position will have to come back to this.

 

can confirm. caret position doesnt do anythning but stringposition does. Unity 2023.1.16f1
