Set direction Rotation when adding force 2d

Questions & Answers

Hi, I’ve got a game where a 2d sprite randomly moves around the screen, this is done like this:

using UnityEngine;
using System.Collections;

public class RandomMove: MonoBehaviour {

public float MinForce = 20f;
public float MaxForce = 40f;
public float DirectionChangeInterval = 1f;

private float directionChangeInterval;
public new Rigidbody2D rigidbody2D;

void Awake() {
    rigidbody2D = GetComponent<Rigidbody2D>();
}

// Use this for initialization
void Start () {
    directionChangeInterval = DirectionChangeInterval;
    push();
}

// FixedUpdate is called after a set time interval
void FixedUpdate () {
    directionChangeInterval -= Time.deltaTime;
    if (directionChangeInterval < 0) {
        push();
        directionChangeInterval = DirectionChangeInterval;
    }
}

void push() {
    float force = Random.Range(MinForce, MaxForce);
    float x = Random.Range(-1f, 1f);
    float y = Random.Range(-1f, 1f);
  
    rigidbody2D.AddForce(force * new Vector2(x, y));
}

}

I’d like to setup push so that it will also change the object to face the direction it’s moving (the Z rotation), but I haven’t had any luck. I’ve been googling and trying things but, nothing so far. I need a way to get the Z value that would leave it facing the new direction.

@tobiasW sadly that has similar results. Abhiroop’s suggestion of adding 180 if both x and y are negative didn’t work either. :confused: I do appreciate the help, though.

Just debug the values of rotation you are getting and then you can figure out where you are going wrong. It should be something really silly.
