What’s “ritham”?

You are probably missing the using UnityEngine.UI; line from the top of the script.

yoooooooo that worked but… I now have to more errors:
Assets\noteOn.cs(24,32): error CS0029: Cannot implicitly convert type ‘UnityEngine.UI.Image’ to ‘UnityEngine.Texture’

Assets\noteOn.cs(28,32): error CS0029: Cannot implicitly convert type ‘UnityEngine.UI.Image’ to ‘UnityEngine.Texture’
here is my new code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class noteOn : MonoBehaviour
{
    // Start is called before the first frame update
    public Image defaultImage;
    public Image pressedImage;
    public RawImage RawImage;

    public KeyCode keyToPress;
    void Start()
    {
        RawImage = GetComponent<RawImage>();
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(keyToPress))
        {
            RawImage.texture = pressedImage;
        }
        if (Input.GetKeyUp(keyToPress))
        {
            RawImage.texture = defaultImage;
        }
    }
}

Why are you using RawImage? Is it important? Or why are you using Image for the others? I suggest reading up in the manual which one is good for your use case and use the one which suits your use case the best.

So this forum isn’t your personal fat-finger lazy typo correction service. If you are spelling ‘ritham’ incorrectly, that’s a really really bad sign. You’re going to have a seriously rough time with programming, where 100% of every character must be 100% perfect in every way.

How to do tutorials properly:

Tutorials are a GREAT idea. Tutorials should be used this way:

Step 1. Follow the tutorial and do every single step of the tutorial 100% precisely the way it is shown. Even the slightest deviation (even a single character!) generally ends in disaster. That’s how software engineering works. Every single letter must be spelled, capitalized, punctuated and spaced (or not spaced) properly. Fortunately this is the easiest part to get right. Be a robot. Don’t make any mistakes. BE PERFECT IN EVERYTHING YOU DO HERE.

If you get any errors, learn how to read the error code and fix it. Google is your friend here. Do NOT continue until you fix the error. The error will probably be somewhere near the parenthesis numbers (line and character position) in the file. It is almost CERTAINLY your typo causing the error, so look again and fix it.

Step 2. Go back and work through every part of the tutorial again, and this time explain it to your doggie. See how I am doing that in my avatar picture? If you have no dog, explain it to your house plant. If you are unable to explain any part of it, STOP. DO NOT PROCEED. Now go learn how that part works. Read the documentation on the functions involved. Go back to the tutorial and try to figure out WHY they did that. This is the part that takes a LOT of time when you are new. It might take days or weeks to work through a single 5-minute tutorial. Stick with it. You will learn.

Step 2 is the part everybody seems to miss. Without Step 2 you are simply a code-typing monkey and outside of the specific tutorial you did, you will be completely lost.

Of course, all this presupposes no errors in the tutorial. For certain tutorial makers (like Unity, Brackeys, Imphenzia, Sebastian Lague) this is usually the case. For some other less-well-known content creators, this is less true. Read the comments on the video: did anyone have issues like you did? If there’s an error, you will NEVER be the first guy to find it.

Beyond that, Step 3, 4, 5 and 6 become easy because you already understand!

Remember: NOBODY memorizes error codes. The error code is absolutely the least useful part of the error. It serves no purpose at all. Forget the error code. Put it out of your mind.

The complete error message contains everything you need to know to fix the error yourself.

Always start with the FIRST error in the list, as sometimes that error causes or compounds some or all of the subsequent errors.

The important parts of the error message are:

  • the description of the error itself (google this; you are NEVER the first one!)
  • the file it occurred in (critical!)
  • the line number and character position (the two numbers in parentheses)

All of that information is in the actual error message and you must pay attention to it. Learn how to identify it instantly so you don’t have to stop your progress and fiddle around with the forum.

        if (Input.GetKeyDown(keyToPress))
        {
            RawImage.sprite = pressedImage;

        {
            RawImage.sprite = defaultImage;
        }
    }
}

now it do not like me saying image or sprites to change the sorce image
errors:
Assets\noteOn.cs(24,31): error CS0029: Cannot implicitly convert type ‘UnityEngine.UI.Image’ to ‘UnityEngine.Sprite’

Assets\noteOn.cs(28,31): error CS0029: Cannot implicitly convert type ‘UnityEngine.UI.Image’ to ‘UnityEngine.Sprite’

Please see the Learn section and go through the beginner tutorials there, or search the forums. Those are very simple errors that literally contain issue and line number in the error. This is considered a Low Effort post, posting a script and an error and saying help is the point of these forums.
