How to make a sprite walk on its own?

Ah okay, of course I could send it, here it is:

{ { void Update () { comprobarDistancia(); if (walk) Walk (); else if(!walk && !isWaiting){ StartCoroutine(Wait()); }

  }

IEnumerator Wait(){ isWaiting = true; animation.CrossFade ("idle"); yield return new WaitForSeconds (5.0f); walk = true; isWaiting = false;

You can do the following steps and write the following code and see if it works for you...

STEPS

1. Create a gameObject in the scene

2. Add a rigidbody component to it

3. Add a 2d collider to it (example: BoxCollider2D)

4. Create a new script call it NpcBehaviour

5. Write the following code...

CODE using UnityEngine; public class NpcBehaviour : MonoBehaviour { public float speed; public float moveRate; public int dirX; public int dirY; private float moveCounter; private new Rigidbody2D rigidbody2D { get { return GetComponent<Rigidbody2D>() ?? default(Rigidbody2D); } } private void Update () { if (rigidbody2D) { if (moveCounter > moveRate) { ChangeDirection(); moveCounter = 0f; } Vector2 vel = new Vector2(dirX * speed, dirY * speed); rigidbody2D.velocity = Vector2.Lerp(rigidbody2D.velocity, vel, Time.deltaTime * 10f); moveCounter += Time.deltaTime; } } private void ChangeDirection () { dirX = Random.Range(-1, 1); // -1 or 0 or 1 dirY = Random.Range(-1, 1); // -1 or 0 or 1 } }

FINAL STEP 1. Attach the script to the desired game object

Hope this helps!
