how to cross out a certain text displayed on the screen? - unity3d

Question

In my game, there are certain objects that are tagged with "TargetObj", these objects have their names displayed on the screen like this:
GameObject[] targetObjects;
List<GameObject> targetObjectsList;
private TextMeshProUGUI mytext;
public TMP_FontAsset FontAssetA;
[SerializeField] GameObject TargetsCanvas;
void Start()
{
mainCamera = Camera.main;
targetObjects = GameObject.FindGameObjectsWithTag("TargetObj");
targetObjectsList = new List<GameObject>();
foreach (var obj in targetObjects)
{
mytext = CreateText(TargetsCanvas.transform);
mytext.text = "• " + obj.name;
mytext.font = FontAssetA;
}
}
static TextMeshProUGUI CreateText(Transform parent)
{
var go = new GameObject();
go.transform.parent = parent;
var text = go.AddComponent<TextMeshProUGUI>();
text.fontSize = 20;
return text;
}
They look like this:
The TargetsCanvas inspector:
Once the player picks up all tagged objects, he wins:
if (PickingUp)
{
if (currentlyPickedUpObject == null)
{
if (lookObject != null)
{
PickupObject();
if (lookObject.CompareTag("TargetObj") && !targetObjectsList.Contains(lookObject.gameObject))
{
if (aSource)
{
aSource.Play();
}
targetObjectsList.Add(lookObject.gameObject);
if (targetObjectsList.Count == targetObjects.Length)
{
winUI.SetActive(true);
Time.timeScale = 0f;
//SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex + 1);
//Time.timeScale = 1f;
}
}
}
public void PickupObject()
{
physicsObject = lookObject.GetComponentInChildren<PhysicsObjects>();
currentlyPickedUpObject = lookObject;
pickupRB = currentlyPickedUpObject.GetComponent<Rigidbody>();
pickupRB.constraints = RigidbodyConstraints.FreezeRotation;
physicsObject.playerInteractions = this;
pickupRB.transform.parent = PickupParent.transform;
//StartCoroutine(physicsObject.PickUp());
}
I'm trying to cross out the name object on the screen once this object is picked up. I know that I can use this line to cross out a text:
mytext.fontStyle = FontStyles.Strikethrough;
but in my case, I don't know where exactly to use it to achieve what I want. any idea?

When using TextMeshPro Text, you can add a rich text tags to strikethrough any part of your string.
For example:
Make sure Rich Text is enabled under Extra Settings in your TMP Text Component
Use start tag <s> and end tag </s> to define where the strikethrough starts and ends
An example of setting this in code would be something like
public string textToStrike; //"Coffee Cup"
const string STRIKE_START = "<s>";
const string STRIKE_END = "</s>";
outputText = STRIKE_START + textToStrike + STRIKE_END;
Result outputText = Coffee Cup
You could even make a method that returns the inputted value as striked out if you wanted.
For example
private string StrikeText(string input)
{
string output = STRIKE_START + input + STRIKE_END;
return output;
}
