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

    Here is how to read errors and make sense of them, get actual guidance from them:

    Always start with the FIRST error in the console window, 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)
    - also possibly useful is the stack trace (all the lines of text in the lower console window)

    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.

    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.

    Also, code screenshots are not a thing. If you post a code snippet, ALWAYS USE CODE TAGS:

    Look at the line numbers 22 and 25 as the errors tell you.

    Notice anything funny there?

    If you don't, make a new script and look at the blank script.

    What is NOT in that new blank script twice?

    Seriously, if you are going to monkey-hammer-bang tutorials code in, you have GOT to pay attention to precision on this stuff, there really is no other way.

    This will save you a LOT of time:

    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!

    It is set up perfectly.

    Read the error text, figure out the line.

    Go back over the line with that error word in it and PAY ATTENTION TO CAPITALIZATION!!!

    Again, you absolutely cannot mis-type, misspell, or miscapitalization ANYTHING.

    Be a robot. Don't make any mistakes. BE PERFECT IN EVERYTHING YOU DO HERE.

    Ok... This is not how game development (or any development) works. You are typing something out, getting an error and just posting that error and code on forum. This forum is to help people with learning to use Unity provide support to each other.

    HOWEVER, this is forum is not a simple debugging tool, input error > get fix. It is here to HELP people learn. Not do the work for them. Everything you have posted are simple mistakes, basic stuff you wouldn't do if you have done the tutorials and and paid attention. People are here to help each other, but it is assumed you will do the basic work of reading the materials provided. Help? yes! Hold your and teach you? No!

    Closing. Please go through the tutorials on the site, and please google and/or search this site for answers before posting questions like this again.
