[PLEASE HELP!] - Error CS0103 x3 and CS0119.

Unity Engine

Help! I was watching a tutorial on how to make a working gun.

My Error Message(s) is/are:
1. Assets\Scripts\GunScript.cs(40,13): error CS0103: The name ‘allowButtonHold’ does not exist in the current context
2. Assets\Scripts\GunScript.cs(41,25): error CS0119: ‘GunScript.MyInput()’ is a method, which is not valid in the given context
3. Assets\Scripts\GunScript.cs(64,97): error CS0103: The name ‘rayHit’ does not exist in the current context
4. Assets\Scripts\GunScript.cs(66,23): error CS0103: The name ‘rayHit’ does not exist in the current context

Sorry if my code is too long/confusing. Please give me any tips you have for this, tysm.

Also, I left (Line 68 to 71) in comments because I haven’t made the script yet.

My Code is:

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

public class GunScript : MonoBehaviour
{
    //Gun stats
    public int damage;
    public float timeBetweenShooting, spread, range, reloadTime, timeBetweenShots;
    public int magazineSize, bulletsPerTap;
    int bulletsLeft, bulletsShot;

    //Bools
    bool shooting, readyToShoot, reloading;

    //Reference
    public Camera fpsCam;
    public Transform attackPoint;
    public RaycastHit raycastHit;
    public LayerMask whatIsEnemy;
    public Text text;

    private void Awake()
    {
        bulletsLeft = magazineSize;
        readyToShoot = true;
    }

    private void Update()
    {
        MyInput();

        //SetText
        text.text = bulletsLeft + " / " + magazineSize;
    }

    private void MyInput()
    {
        if (allowButtonHold) shooting = Input.GetKey(KeyCode.Mouse0);
        else shooting = MyInput.GetKeyDown(KeyCode.Mouse0);

        if (Input.GetKeyDown(KeyCode.R) && bulletsLeft < magazineSize && !reloading) Reload();

        //Shoot
        if (readyToShoot && shooting && !reloading && bulletsLeft > 0)
        {
            Shoot();
        }
    }

    private void Shoot()
    {
        readyToShoot = false;

        //Spread
        float x = Random.Range(-spread, spread);
        float y = Random.Range(-spread, spread);

        //Calculate Direction with Spread
        Vector3 direction = fpsCam.transform.forward + new Vector3(x, y, 0);

        //Raycast
        if (Physics.Raycast(fpsCam.transform.position, direction, fpsCam.transform.forward, out rayHit, range, whatIsEnemy))
        {
            Debug.Log(rayHit.collider.name);

            /*if (rayHit.collider.CompareTag("Enemy"))
            rayHit.collider.GetComponent<ShootingAi>().TakeDamage(damage);*/

            //of course your Enemy needs to be tagged as "Enemy" and needs to have a script with the TakeDamage function :smile:
        }

        bulletsLeft --;
        Invoke("ResetShot", timeBetweenShooting);

        if (bulletsLeft > 0 && bulletsLeft > 0)
        {
            bulletsShot = bulletsPerTap;
            Shoot();
        }
        Invoke("Shoot", timeBetweenShots);
    }

    private void ResetShot()
    {
        readyToShoot = true;
    }

    private void Reload()
    {
        reloading = true;
        Invoke("ReloadFinished", reloadTime);
    }

    private void ReloadFinished()
    {
        bulletsLeft = magazineSize;
        reloading = false;
    }
}

I am using the latest version fyi

Errors 1, 3, and 4 indicate your code is trying to use variables that aren’t in your script. You most likely missed a few lines of code from the tutorial.

Error 2 is because you wrote “MyInput” where you should have just written “Input”.

Thanks so much

I have the exact same problem can you please tell me how you fixed it

Please don’t necro-post threads.

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.

Finally, to help save you some time:

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…

I got a feeling that this is just a troll…

Actually no, Kurt is one of the most helpful persons on the forum! There are a few of us here. Perhaps you meant the necro-poster!
