✅ How to reference gameObject in OnCollisionEnter2D?

public void OnCollisionEnter2D(Collision2D col)
    {
        if (col.gameObject.tag == "wall_up")
        {
            Debug.Log("Collision detected!");

        }
    }

public void OnCollisionEnter2D(Collision2D col)
    {
        if (col.gameObject.tag == "wall_up")
        {
            Debug.Log("Collision detected!");

        }
    }

I don't want to detect collision of the game object the script is tied to, I want to detect collision of an instantiated object called _cell. How do I reference _cell in the collision function?

❔ How can I make an instantiated object move?

I'm trying to make an object spawned with the instantiate function move, but I can't get it to work. Can anyone help me? public class Spawn_Cells : MonoBehaviour { public GameObject cell; public float speed = 2; public Vector3 cellDirection = new Vector3(1, 1, 0); void Start() { Vector3 randomPosition = new Vector3(Random.Range(10f, -10f), Random.Range(4f, -4f), 0); Instantiate(cell, randomPosition, Quaternion.identity); } void Update() { cell.transform.Translate(cellDirection * speed * Time.deltaTime); } }

❔ How to make instantiated object move using transform function?

public GameObject cell; public float speed = 1; public Vector3 cellDirection = new Vector3(1,1,0); void Start() { Vector3 randomPosition = new Vector3(Random.Range(10, -10), Random.Range(4, -4), 0); Instantiate(cell, randomPosition, Quaternion.identity); } void Update() { cell.transform.Translate(cellDirection * speed * Time.deltaTime); } For now, I wanna spawn a cell in a random place and make it move in a certain direction. The spawning works, but the cell will not move. Can anyone help me with this?

❔ How to make instantiated object move with transform function?

I'm quite new to Unity, so this might be really easy. public GameObject cell; public float speed = 1; public Vector3 cellDirection = new Vector3(1,1,0); void Start() { Vector3 randomPosition = new Vector3(Random.Range(10, -10), Random.Range(4, -4), 0); Instantiate(cell, randomPosition, Quaternion.identity); } void Update() { cell.transform.Translate(cellDirection * speed * Time.deltaTime); } For now, I wanna spawn a cell in a random place and make it move in a certain direction.
