类型或命名空间定义，或预期的文件结尾 (22,1) (UNITY)

Question

Please fix my script, something is wrong! I get this error, and I don't know what's wrong! There's something wrong at the 22nd line.

using System;
using System.Diagnostics;
using System.Web;
using UnityEngine;

public class Target : MonoBehaviour
{
    // Start is called before the first frame update

    public float health = 50f;


    public void TakeDamage (float amount)
    {
        health -= amount;
        if (health <= 0f)
        {
            Die();
        }
    }

    void Die()
    {
        Destroy(gameObject);
    }

}

Easiest things to check:

• This error comes up a lot when you've accidentally put the wrong number of closing curly braces. However I didn't see any problems in the code you posted.
• Double check that there are no extra curly braces or text at the very end of your file.

It's possible that even though you wrote using UnityEngine; , your code editor is bugging out and failing to recognize it. VSCode has been particularly finicky for me lately in similar ways. Here are some things you can try:

• Instead of Destroy(gameObject); try putting UnityEngine.GameObject.Destroy(gameObject); This will force the compiler to use the right namespace for that function.
• If that doesn't help, you may need to reset some things: Try creating your Target file again and copying the code over to the new file. EDIT: Rocketman Dan pointed out that you may need to manually retype some of the code, because there may be problems with invisible characters.
• You may also need to close your project in your code editor and re-open it. You may also need to restart Unity.
• If you use Visual Studio Code, make sure IntelliSense is working correctly.
