So I am able to Instantiate new objects at runtime and they spawn in with the correct scripts attached however the scripts do now spawn in with the variables fixed in their slots.

I need a way to spawn prefabs with the scripts attached AND the variable slots in the script are all filled in.

Deploy capsule script (linked to main camera)

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class deployCapsule : MonoBehaviour
{
    public GameObject CapsulePrefab;
    public Path path;
    public float respawnTime = 1.0f;

    // Start is called before the first frame update
    void Start()
    {
        StartCoroutine(capsuleWave());
    }

    private void spawnCap()
    {
       
        GameObject a = Instantiate(CapsulePrefab) as GameObject;
        a.transform.position = new Vector2(1.0f, 1.0f);
        path.followers.Add(a);
        Debug.Log("1");
    }

    IEnumerator capsuleWave()
    {
        while (true)
        {
            yield return new WaitForSeconds(respawnTime);
            spawnCap();
        }
     
    }
}

Path Follower script

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PathFollower : MonoBehaviour

{
    public float movementSpeed;
    //private float pathProgress = 0;
    public GameObject objectToSpawn;
    public Transform[] positionPoint;
    [Range(0,1)]
    public float value;

    void Start()
    {
        Debug.Log(iTween.PathLength(positionPoint));
    }
    void Update()
    {
        movementSpeed = 10f;
        if (value < 1)
    {
            value  = Time.deltaTime / movementSpeed;
    }
        iTween.PutOnPath(objectToSpawn, positionPoint, value);
    }
    private void OnDrawGizmos()
    {
        iTween.DrawPath(positionPoint,Color.green);
    }
}

I KNOW THIS IS NOT TECHNICALLY POSSIBLE. But I need a method to get this done one way or another.

I am quite new to unity and would appreciate any help given. Thank you in advance.

After instantiating your capsule prefab and assigning a reference to it named a (I suggest you change this naming to something more logical)

GameObject a = Instantiate(CapsulePrefab);

Assuming your prefab already has the PathFollower component attached, you could use the GameObject.GetComponent<T> method to access it.

var pathFollowerComponent = a.GetComponent<PathFollower>();

After which, you could populate the positionPoint[] Transform's array (assuming that's what you're after) with references to the "Points" GameObjects located in the hierarchy and the scene.

It's up to you how to go about this:

• You could create a tag on each point, use GameObject.FindGameObjectsWithTag("Point");
• Obtain the children from the "PathFollower" GameObject and add its child transforms to your array
• Create a singleton instance or a "GameManager" class which stores the points located in a scene
• If you create new points dynamically, create a listener and invoke events to add the new points to the array whenever they're instantiated.

Note that the mentioned above may not return the points in the order you placed them, so you may need to sort them! In general, there are many other ways which you can find by searching the forums, or on Google!

in deployCapsule, store a reference to the array of points

public Transform[] positionPoint;

assign the values in the inspector.

and then once you've instantiated the prefab, give it the array like this

//this is in the SpawnCap function
//GameObject a = Instantiate(CapsulePrefab) as GameObject;
a.GetComponent<PathFollower>().positionPoint = positionPoint;
//rest of your function

alternatively, set the values in the Awake() or Start() function of the newly instantiated Capsule by getting a reference to a class that has the data.

void Start()
{
    positionPoint = GameObject.Find("Spawner").GetComponent<deployCapsule>().positionPoint;
}
