i need help with some errors

Unity Engine
1 
ublic class PlayerMovementScrips : MonoBehaviour {

    private float horizontal;
    private float speed = 8f;
    private float jumpingPower = 16f;
    private bool isFacingRigth = true;

    [SerializeField] private Rigidbody2D rb;
    [SerializeField] private Transform groundCheck;
    [SerializeField] private LayerMask groundLayer;



void Update()
    {
        horizontal = Input.GetAxisRaw("Horizonteal");

        if (Input.GetButtonDown("Jump") && IsGrounded())
        {
            rb.velocity = new Vector2(rb.velocity.x, jumpingPower);
        }



        if (Input.GetButtonDown("Jump") && rb.velocity.y > 0f)
        {
            rb.velocity = __Vector2__(rb.velocity.y * 0.5f);
        }



        Flip();
    }


    private void FixedUpdate()
    {
        rb.velocity = new Vector2(horizontal * speed, rb.velocity.y);

    }


    private bool IsGrounded()
    {
        return Physics2D.OverlapCircle(groundCheck.position, 0.2f, __IsGroundedLayer__);
    }


    private void Flip()
    {
        if (isFacingRigth && horizontal < 0f || !isFacingRigth && horizontal > 0f)
        {
            isFacingRigth = !isFacingRigth;
            Vector3 localScale = transform.localScale;
            localScale.x *= -1f;
            transform.localScale = localScale;
        }
    }
}

the errors are CS1955 and CS0103 and are line 31 and 49
(this is not my own code i have followed a tutorial)

The line #s are all messed up in of your posted code, but where you have

rb.velocity = Vector2(rb.velocity.y * 0.5f);

but it should be

rb.velocity = new Vector2(some_x_value_here, rb.velocity.y * 0.5f);

There may be other errors. The lines you list for where the errors occur do not correspond to your posted code because you didn’t copy/paste the whole page. Also you have some weird formatting in the code, like “__”, which makes it harder to evaluate.__
edit: also, in the method IsGrounded(), you call IsGroundedLayer - I’m not sure where this comes from, is it a property or method? If Method, it needs to be IsGroundedLayer() with parentheses.

The answer is to go back to the tutorial and follow it more precisely TBH. If you cannot follow a tutorial then either the tutorial is bad or you’re not able to follow what it’s telling you to do correctly.

Your code isn’t valid C#, has stuff missing, mistyped etc.

The 2D forum is not for general scripting issues where you don’t understand the C# language and are trying to learn. At best it’s a post for the scripting forum here. I’ll move your post for you.

I’ll add that it’s the same as your previous post here. You just need to follow the tutorial more precisely.

Actually, as Melv notes, you have failed to follow the tutorial and instead you have made typographic mistakes.

Fortunately the compiler is giving you information so that you can fix them all by yourself! Here is how:

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

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)

Always start with the FIRST error in the console window, as sometimes that error causes or compounds some or all of the subsequent errors. Often the error will be immediately prior to the indicated line, so make sure to check there as well.

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 here memorizes error codes. That’s not a thing. 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.

Tutorials and example code are great, but keep this in mind to maximize your success and minimize your frustration:

How to do tutorials properly, two (2) simple steps to success:

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 step must be taken, every single letter must be spelled, capitalized, punctuated and spaced (or not spaced) properly, literally NOTHING can be omitted or skipped.
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 your error. Google is your friend here. Do NOT continue until you fix your error. Your 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. If you want to learn, you MUST do Step 2.

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!

Finally, when you have errors… see the start of this post!
