Resolved The movement of one prefab imposes on its clone

Hi all, ran into this problem. When quickly creating a prefab, the movement overlaps each other. After googling I could not find a solution. If anyone has encountered this problem and can tell me how to solve it, I would be grateful for help.
Unity - 2021.3.14f1

Video demonstration:

Movement code:

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3.  
4. public class MissileMovement : MonoBehaviour
5. {
6.     [SerializeField] private BoxCollider _pointRadius1;
7.     [SerializeField] private BoxCollider _pointRadius2;
8.    
9.     private Vector3 _intermediatePoint1;
10.     private Vector3 _intermediatePoint2;
11.  
12.     private const float FinalPosition = 1f;
13.     private readonly float _scaleCollider = 2f;
14.  
15.     public IEnumerator MoveUp(Vector3 startPosition, Vector3 endPosition, float position, GameObject missile, float speed)
16.     {
17.         _intermediatePoint2 = GetRandomPointInBounds(_pointRadius2, _scaleCollider);
18.  
19.         while (FinalPosition != position)
20.         {
21.             position += speed * Time.deltaTime;
22.  
23.             missile.transform.position = GetTrajectoryMove(startPosition, _intermediatePoint2,endPosition, position);
24.             missile.transform.rotation = GetRotation(startPosition, _intermediatePoint2,endPosition, position);
25.  
26.             yield return null;
27.         }
28.     }
29.    
30.     public IEnumerator MoveDown(Vector3 startPosition, Vector3 endPosition, float position, GameObject missile, float speed)
31.     {
32.         _intermediatePoint1 = GetRandomPointInBounds(_pointRadius1, _scaleCollider);
33.  
34.         while (FinalPosition != position)
35.         {
36.             yield return null;
37.  
38.             position += speed * Time.deltaTime;
39.            
40.             missile.transform.position = GetTrajectoryMove(startPosition, _intermediatePoint1, endPosition, position);
41.             missile.transform.rotation = GetRotation(startPosition, _intermediatePoint1,endPosition, position);
42.         }
43.     }
44.  
45.     private Quaternion GetRotation(Vector3 startPosition,Vector3 intermediatePoint, Vector3 endPosition, float position)
46.     {
47.         Quaternion rotation = Quaternion.LookRotation(CurveBizier.GetFirstDerivative(
48.             startPosition,
49.             intermediatePoint,
50.             endPosition,
51.             position));
52.  
53.         return rotation;
54.     }
55.    
56.     private Vector3 GetTrajectoryMove(Vector3 startPosition,Vector3 intermediatePoint, Vector3 endPosition, float position)
57.     {
58.         Vector3 trajector = CurveBizier.GetPoint(
59.             startPosition,
60.             intermediatePoint,
61.             endPosition,
62.             position);
63.  
64.         return trajector;
65.     }
66.  
67.     private Vector3 GetRandomPointInBounds(Collider collider, float scale)
68.     {
69.         Bounds bounds = collider.bounds;
70.         Vector3 point = new Vector3(
71.             Random.Range(bounds.min.x * scale, bounds.max.x * scale),
72.             Random.Range(bounds.min.y * scale, bounds.max.y * scale),
73.             Random.Range(bounds.min.z * scale, bounds.max.z * scale));
74.  
75.         return point;
76.     }
77. }

Prefab creation code:

Code (CSharp):

1. using UnityEngine;
2.  
3. [RequireComponent(typeof(MissileMovement))]
4. public class Missile : MonoBehaviour
5. {
6.     [SerializeField] private float _speed;
7.     [SerializeField] private GameObject _missilePrefab;
8.     [SerializeField] private Camera _mainCamera;
9.    
10.     private MissileMovement _movement;
11.     private float _position = 0;
12.  
13.     private void Start()
14.     {
15.         _movement = GetComponent<MissileMovement>();
16.     }
17.  
18.     public void Launch(Vector3 mousePosition)
19.     {
20.         Ray ray = _mainCamera.ScreenPointToRay(mousePosition);
21.  
22.         if (Physics.Raycast(ray, out RaycastHit hit))
23.         {
24.             var position = _mainCamera.transform.position;
25.  
26.             if (hit.collider && hit.point.y <= Vector3.down.y)
27.             {
28.                 GameObject missile1 = Instantiate(_missilePrefab, position, Quaternion.identity);
29.                 StartCoroutine(_movement.MoveDown(position, hit.point, _position, missile1, _speed));
30.             }
31.            
32.             if(hit.collider && hit.point.y >= Vector3.up.y)
33.             {
34.                 GameObject missile2 = Instantiate(_missilePrefab, position, Quaternion.identity);
35.                 StartCoroutine(_movement.MoveUp(position, hit.point, _position, missile2, _speed));
36.             }
37.         }
38.     }
39. }

 

Line 29 and Line 35 above operate on

_movement

, your prefab.

You need to operate on the instance of MissileMovement that you just spawned.

 

Thank you so much for the advice, now everything works as I wanted it to.
