    I am new to scripting and I am looking for a way to get the color changed for specific words when they are written in the input text field and change it back to normal color for the others.
    I tried but I am not able to achieve this.
    I am only able to change the color when the word is written but not back to normal.
    Please help

    The basic process is just string slicing and dicing, injecting
    <color=##123456>
    and
    </color>
    where you need it.

    You're welcome to see the color processing in my Typewriter script, attached below.

    Thank you for helping me out.

    I tried your method and got to know that using regular expression would be more optimized.
    With some youtube video I made a script in which whenever the first time a word is found it changes color and go back to normal but doesnot work for other keywords, also I am not able to use backspace to delete the letters.
    Can you give me some hint on how to achieve this.

    Do you actually care about optimization?! How many of these things do you have going?!

    I gave you a fully-functional HTML color tag slicer-and-dicer above. Use it and when you have a performance problem, then think about regular expressions.

    Otherwise, go practice regex and how to use it. We know it works, so do some debugging and get it working.

    You must find a way to get the information you need in order to reason about what the problem is.

    Once you understand what the problem is, you may begin to reason about a solution to the problem.

    What is often happening in these cases is one of the following:

    - the code you think is executing is not actually executing at all
    - the code is executing far EARLIER or LATER than you think
    - the code is executing far LESS OFTEN than you think
    - the code is executing far MORE OFTEN than you think
    - the code is executing on another GameObject than you think it is
    - you're getting an error or warning and you haven't noticed it in the console window

    To help gain more insight into your problem, I recommend liberally sprinkling
    Debug.Log()
    statements through your code to display information in realtime.

    Doing this should help you answer these types of questions:

    - is this code even running? which parts are running? how often does it run? what order does it run in?
    - what are the values of the variables involved? Are they initialized? Are the values reasonable?
    - are you meeting ALL the requirements to receive callbacks such as triggers / colliders (review the documentation)

    Knowing this information will help you reason about the behavior you are seeing.

    You can also supply a second argument to Debug.Log() and when you click the message, it will highlight the object in scene, such as
    Debug.Log("Problem!",this);


    If your problem would benefit from in-scene or in-game visualization, Debug.DrawRay() or Debug.DrawLine() can help you visualize things like rays (used in raycasting) or distances.

    You can also call Debug.Break() to pause the Editor when certain interesting pieces of code run, and then study the scene manually, looking for all the parts, where they are, what scripts are on them, etc.

    You can also call GameObject.CreatePrimitive() to emplace debug-marker-ish objects in the scene at runtime.

    You could also just display various important quantities in UI Text elements to watch them change as you play the game.

    If you are running a mobile device you can also view the console output. Google for how on your particular mobile target, such as this answer or iOS: https://forum.unity.com/threads/how-to-capturing-device-logs-on-ios.529920/ or this answer for Android: https://forum.unity.com/threads/how-to-capturing-device-logs-on-android.528680/

    If you are working in VR, it might be useful to make your on onscreen log output, or integrate one from the asset store, so you can see what is happening as you operate your software.

    Another useful approach is to temporarily strip out everything besides what is necessary to prove your issue. This can simplify and isolate compounding effects of other items in your scene or prefab.

    Here's an example of putting in a laser-focused Debug.Log() and how that can save you a TON of time wallowing around speculating what might be going wrong:

    When in doubt, print it out!(tm)

    Note: the
    print()
    function is an alias for Debug.Log() provided by the MonoBehaviour class.
