Question Camera Follow Code worked in 2022 - spring, didn't work in 2022-23 school year - help!

Cinemachine is a standard Unity package available in the package manager, it's not a separate installer. Your existing project will be comprised of packages that it downloaded.

 

If the code above is in a script, please post the full script using code-tags as requested above although TBH, your debugging should verify that this script is on a GameObject in the scene. You can easily verify if the "LateUpdate" is running by adding a Debug.Log() to it.

Nobody can debug or tell you what is wrong from a plain-text code snippet really.

 

The link above shows you how to use code-tags. They end up looking like this:

Code (CSharp):

1. // Class Variables
2. private Transform playerTransform;
3. public float offset;

Regardless, the PlayerMovement code has an oddity:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. // Project: PlayGround2
5. // Script:  PlayerMovement
6. // Author:  Dillard  04/19/2023
7. // Purpose: Allow player sprite to move left and right with keys
8. //          Allow player sprite to jump
9. //          Player sprite has 2d effects - Rigid body, box collider
10. //          Ground sprite has 2d effects - box collider
11.  
12. public class PlayerMovement : MonoBehaviour
13. {
14.     // Class Variables
15.     public Rigidbody2D body;
16.     [SerializeField] private float speed;
17.  
18.     // Start is called before the first frame update
19.     void Start()
20.     {
21.         body.GetComponent<Rigidbody2D>();
22.     }
23.  
24.     // Update is called once per frame
25.     void Update()
26.     {
27.         // This code makes it go left and right (arrow keys) - It only affects the horizontal movement
28.  
29.         body.velocity = new Vector2(Input.GetAxis("Horizontal") * speed, body.velocity.y);
30.  
31.         // This is the code that makes it jump - IT only affects vertical movement
32.         if (Input.GetKey(KeyCode.Space))
33.             body.velocity = new Vector2(body.velocity.x, speed);
34.  
35.     }
36. }

Line 21, "body.GetComponent<Rigidbody2D>();" gets the Rigidbody2D component you've presumably set in the inspector and then grabs itself but doesn't do anything with the results. You can remove this line, it does nothing.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CameraFollow : MonoBehaviour
6. {
7.     // Class Variables
8.     private Transform playerTransform;
9.     public float offset;
10.  
11.     // Start is called before the first frame update
12.     void Start()
13.     {
14.         //This finds a game object that is tagged as player and pulls in it's transform data.
15.         //In Unity I tagged the Player object with the Tag - Player
16.  
17.         playerTransform = GameObject.FindGameObjectWithTag("Player").transform;
18.         //body = GetComponent<Rigidbody2D>();
19.     }
20.  
21.     // Update is called once per frame
22.     void Update()
23.     {
24.      
25.     }
26.  
27.     // Update is called once per frame (Update gets the position of all objects every frame)
28.     // LateUdate is called after Update() and FixedUpdate().  (Takes the positions that update got and reacts to it.)
29.  
30.     void LateUpdate()
31.     {
32.         // I need to capture the position of the camera in a temp variable.
33.         Vector3 temp = transform.position;
34.         // I need to modify the position of the camera, using the temp variable to account for the Players position.
35.         temp.x = playerTransform.position.x;
36.         temp.x += offset;
37.         temp.y = playerTransform.position.y;
38.         // I need to reset the position of the camera, accounting for the players position.
39.         transform.position = temp;
40.     }
41. }

So as above, you need to DEBUG this yourself. We don't have the project, it's not fully described by this code.

• Is the LateUpdate running? Add a Debug.Log to verify
• If so then is the playerTransform set to the thing you are tracking. Verify! If you have more than a single GO with that tag, you won't be getting the one you think. As a test, make the "playerTransform" field public and drag the correct one into it.

A small thing but you can simplify the code:

Code (CSharp):

1. void LateUpdate()
2. {
3.     Debug.Log("LateUpdate is running!");
4.  
5.     // The camera position is the player position plus the X-axis offset.
6.     transform.position = playerTransform.position + new Vector3(offset, 0f, 0f);
7. }

Hope this helps.
