[code] screen wrap [code]

this is a code that is supposed to make the ship appear from left after it disappears in right but I don't get the errors showing in unity
can someone tell me what their context means?

 

You are declaring the FixedUpdate method inside the Update method. Don't do that.

Also, post code directly into the forums using CODE tags instead of posting images. If you had, someone can just make a quick edit to your code to show you how to fix the issue, but not when you post images.

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ship : MonoBehaviour
6. {
7.  
8.     // Use this for initialization
9.     public Rigidbody2D RB;
10.     public CircleCollider2D circle;
11.     public int Thrustforce = 5;
12.     int MoveUnitsPerSecond = 5;
13.     public Vector2 thrustdirection = new Vector2(1, 0);
14.     void Start()
15.     {
16.         RB = GetComponent<Rigidbody2D>();
17.         circle = GetComponent<CircleCollider2D.Radius>();
18.     }
19.     void FixedUpdate()
20.     {
21.         RB.AddForce(Thrustforce * thrustdirection);
22.     }
23.  
24.     void update()
25.     {
26.         float horizontalInput = Input.GetAxis("Thrust");
27.         if (horizontalInput > 0)
28.         {
29.             Vector3 position = transform.position;
30.             position.x += horizontalInput * MoveUnitsPerSecond * Time.deltaTime;
31.             transform.position = position;
32.         }
33.     }
34.         float buffer = 1.0f;
35.         void FixedUpdate()
36.         {
37.             if (transform.position.x < ScreenUtils.screenLeft - buffer)
38.             {
39.                 transform.position = new Vector2(ScreenUtils.screenRight - 0.1f, transform.position.y);
40.             }
41.             if (transform.position.x > ScreenUtils.screenRight)
42.             {
43.                 transform.position = new Vector2(ScreenUtils.screenRight - 0.1f, transform.position.y);
44.             }
45.  
46.        
47.     }
48. }

I fixed the update mistake but now there's that single error and I think it's because I used fixedupdate twice when I renamed it, it got worse

 

Yeah now you have FixedUpdate defined twice. Once towards the top, and again towards the bottom. If you need the code in both, consolidate them to a single FixedUpdate method.

 

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class ship : MonoBehaviour
6. {
7.  
8.     // Use this for initialization
9.     public Rigidbody2D RB;
10.     public CircleCollider2D circle;
11.     public int Thrustforce = 5;
12.     int MoveUnitsPerSecond = 5;
13.     public Vector2 thrustdirection = new Vector2(1, 0);
14.     void Start()
15.     {
16.         RB = GetComponent<Rigidbody2D>();
17.         circle = GetComponent<CircleCollider2D.Radius>();
18.     }
19.  
20.     void update()
21.     {
22.         float horizontalInput = Input.GetAxis("Thrust");
23.         if (horizontalInput > 0)
24.         {
25.             Vector3 position = transform.position;
26.             position.x += horizontalInput * MoveUnitsPerSecond * Time.deltaTime;
27.             transform.position = position;
28.         }
29.     }
30.     float buffer = 1.0f;
31.     void FixedUpdate()
32.     {
33.         RB.AddForce(Thrustforce * thrustdirection);
34.         if (transform.position.x < ScreenUtils.screenLeft - buffer)
35.         {
36.             transform.position = new Vector2(ScreenUtils.screenRight - 0.1f, transform.position.y);
37.         }
38.         if (transform.position.x > ScreenUtils.screenRight)
39.         {
40.             transform.position = new Vector2(ScreenUtils.screenRight - 0.1f, transform.position.y);
41.         }
42.     }
43.  
44.  
45. }
46.  
47.  
48.  

when I join them together this happens

 

Change "void update()" to "void Update()".
