[SOLVED] 2D Collision problem

Unity Engine
1

Hi everyone. I’m trying to do something very simple, when my “player” is on the ground, a text is set to true, but as you can see it does not work…

public class PlayerController : MonoBehaviour {

    Rigidbody2D rb;
    public float speed;
    public Text bottomText;
    public Text topText;
    bool isOnGround;
    bool isOnTop;
    // Use this for initialization
    void Start () {
        rb = gameObject.GetComponent<Rigidbody2D> ();
    }
   
    // Update is called once per frame
    void Update () {


        if (Input.GetKeyDown ("right")) {
                rb.velocity = new Vector2 (speed, 0);
        }
        if (Input.GetKeyDown ("left")) {
                rb.velocity = new Vector2 (-speed, 0);
        }
        if (Input.GetKeyDown ("up")) {
                rb.velocity = new Vector2 (0, speed);
        }

        bottomText.text = isOnGround.ToString();
        topText.text = isOnTop.ToString();
    }

    void OnCollisionEnter(Collision col){

        if(col.gameObject.tag == "ground"){
            isOnGround = true;
        }
        if(col.gameObject.tag == "top"){
            isOnTop = true;
        }
    }
}

Object has gravity?

Can you make player jump and watch it fall back to ground? Does OnCollisionEnter trigger when this happens? Try using Debug.Log(col.gameObject.name) in function to see in output log what all is detected during collision.

I’ve already solved this. The problem was that i was using “OnCollisionEnter” instead “OnCollisionEnter2D”. Thank you!
