You can use our Themes SDK Github to search things. For example searching for OffTrack would have found it:
https://github.com/appgineerin/ATVO-Themes-SDK/search?q=offtrack&unscoped_q=offtrack


To extend the time how long the text shows, in general the strategy can be:

• When offtrack is detected, store the current time
• Each update, check if there is a stored offtrack time
• If there is, check how long ago that time was. If it was shorter than 3 seconds ago, display the offtrack text
• If not, display nothing.

There is one important detail though with regards to tickers: each copy of the ticker item uses its own instance of a converter script, so in principle you can store the last offtrack time without having to worry which driver you are storing it for. However, for a paging ticker, the same template copy is re-used for different drivers (when the page changes). So for robustness, you should store the offtrack time in a lookup table where you can store and retrieve the time for each driver separately. The most common way is to use a Dictionary. Example below:

using System;
using ATVO.ThemesSDK;
using ATVO.ThemeEditor.ThemeModels;
using ATVO.ThemeEditor.Scripting.DotNET;
using ATVO.ThemesSDK.Data.Results;
using System.Collections.Generic;
using ATVO.ThemesSDK.Data.Enums;

namespace Scripts
{
	public class Offtrack : IScript
	{
		// The time to display the text
		private TimeSpan OfftrackShowTime = TimeSpan.FromSeconds(3);	
		
		// Store the time when the last offtrack was detected
		// Store it separately for each car index
		private Dictionary<int, DateTime> _offtrackStartTimes = new Dictionary<int, DateTime>();
		
		public object Execute(ThemeContentItem item, object value, string parameter, ISimulation sim)
		{
			var result = (IEntitySessionResult)value;
			var carIndex = result.Entity.CarIdx;

			if (result.Entity.Car.Movement.TrackLocation == TrackLocation.OffTrack)
			{
				// Update the last detected offtrack time for this car index
				_offtrackStartTimes[carIndex] = DateTime.Now;
			}
			
			// Check if there is a stored time
			if (_offtrackStartTimes.ContainsKey(carIndex))
			{
				// If the stored time is shorter than the desired OfftrackShowTime, display offtrack
				var elapsedTime = DateTime.Now - _offtrackStartTimes[carIndex];
				if (elapsedTime < OfftrackShowTime)
				{
					return "OFFTRACK";
				}
			}

			return "";
		}
	}
}
