Question (8,5): error CS8803: Top-level statements must precede namespace and type declarations

Hello, im having trouble with this error, on line 8, 5.
I had a error like this not too long ago but I think that the error is not in the line that it shows so I don't know.
Here's the code:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class moimientoo : MonoBehaviour{}
6.  
7.  
8.     bool jump;
9.     bool move;
10.  
11.     // Start is
12.     // called before the first frame update
13.     void Start()
14.     {
15.  
16.     }
17.  
18.     // Update is called once per frame  
19.     void Update()
20.     {
21.         if (Input.GetKey("left"))
22.         {
23.             gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(-1000 * Time.deltaTime, 0));
24.         }
25.  
26.         if (Input.GetKey("right"))
27.         {
28.             gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(1000 * Time.deltaTime, 0));
29.         }
30.         if (Input.GetKeyDown("up") && jump)
31.         {
32.             gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0, 250f));
33.         }
34.     }
35.  
36. void OnCollisionEnter2D(Collision2D collision)
37. {
38.     if (collision.transform.tag == "zuelo")
39.     {
40.         jump = true;
41.     }
42. }

 

Removing the curly braces just gives me a LOT of errors

 

Yes but I only have one error. When I remove the braces, 8 new errors appear.

 

Thanks! But now im getting the same thing in line 13,5, but, it seems I have the braces

 

The error is always either on the line or somewhere before that line that is reported. The compiler reads your code just like you would read a book. From the top left to the right and line by line downwards. An earier mistake might only surface at a later point in time.

In line 5 you declared a new class type named "moimientoo". However the body of that class is started and ended on the same line since you have the

{

and

}

right on the same line. That means your class declaration is finished at that point. That means the code in line 8 makes no sense since you try to declare a variable but you're not inside a class / type definition. What you want is this:

Code (CSharp):

1.     using System.Collections;
2.     using System.Collections.Generic;
3.     using UnityEngine;
4.    
5.     public class moimientoo : MonoBehaviour
6.     {
7.         bool jump;
8.         bool move;
9.    
10.         // Start is
11.         // called before the first frame update
12.         void Start()
13.         {
14.    
15.         }
16.    
17.         // Update is called once per frame
18.         void Update()
19.         {
20.             if (Input.GetKey("left"))
21.             {
22.                 gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(-1000 * Time.deltaTime, 0));
23.             }
24.    
25.             if (Input.GetKey("right"))
26.             {
27.                 gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(1000 * Time.deltaTime, 0));
28.             }
29.             if (Input.GetKeyDown("up") && jump)
30.             {
31.                 gameObject.GetComponent<Rigidbody2D>().AddForce(new Vector2(0, 250f));
32.             }
33.         }
34.    
35.         void OnCollisionEnter2D(Collision2D collision)
36.         {
37.             if (collision.transform.tag == "zuelo")
38.             {
39.                 jump = true;
40.             }
41.         }
42.     }

Note that you currently set your "jump" variable to true when you start colliding with something. However you never set the variable back to false anywhere. You may want to use OnClooisionStay2D instead to set it to true and set the variable to false when you actually jump. Though that's up to you.

 

No. You have nine errors. One of them is hiding the other eight. C# will do that with some errors. In this case you're not using opening/closing curly braces correctly. A class should have a pair the surrounds everything belonging to that class. A method should have a pair that surround everything belonging to the method.

If you accidentally leave part of your class outside of the class curly braces or part of the method outside of the method curly braces you will get errors like that (it won't always be that specific error).
