Make StackColors in Unity – Pickup Interaction (Lesson 6)

For this lesson on how to create StackColors in Unity, we will begin programming the interaction between our player object and the pickups. This interaction is that the pickup objects should become part of the player object and stack on top of each other.

public class PlayerControllerStackColor : MonoBehaviour
{
    [SerializeField] Color myColor;

    Rigidbody myRB;

    [SerializeField] float lerpSpeed;

    Transform parentPickup;
    [SerializeField] Transform stackPosition;

    // Start is called before the first frame update
    void Start()
    {
        SetColor(myColor);

        myRB = GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update()
    {
        if(isPlaying)
        {
            MoveForward();
        }

        {

            if(isPlaying == false)
            {
                isPlaying = true;
            }
            MoveSideways();
        }
        

        
    }

    void SetColor(Color colorIn)
    {
        myColor = colorIn;
        for(int i = 0; i <myRends.Length; i++)
        {
            myRends[i].material.SetColor("_Color", myColor);
        }
    }

        {
            transform.position = Vector3.Lerp(transform.position, new Vector3(hit.point.x, transform.position.y, transform.position.z), lerpSpeed *Time.deltaTime);
        }
    }

    private void OnTriggerEnter(Collider other)
    {

        if(other.tag == "Pickup")
        {
            Transform otherTransform = other.transform.parent;
            GameControllerStackColor.instance.UpdateScore(otherTransform.GetComponent<PickupStackColor>().value);

            Rigidbody otherRB = otherTransform.GetComponent<Rigidbody>();
            otherRB.isKinematic = true;
            other.enabled = false;
            if(parentPickup == null)
            {
                parentPickup = otherTransform;
                parentPickup.position = stackPosition.position;
                parentPickup.parent = stackPosition;
            }
            else

                otherTransform.parent = parentPickup;
