Question

I wanted to create a script, that moves an object in one direction and changes the direction of the movement every three seconds. But it returns error. Could you please see what is wrong here?

    var speed = Vector3 (0, 0, 0);


function Start() 
{
var randomDirection : Vector3 = new Vector3(Random.Range(-359, 359),0,Random.Range(-359, 359));
StartCoroutine(ChangeDirection(3.0));
}




function Update()
{
rigidbody.MovePosition(rigidbody.position + speed * Time.deltaTime);



}




function ChangeDirection (waitTime : float) 
{
yield WaitForSeconds (waitTime);
var randomDirection : Vector3 = new Vector3(Random.Range(-359, 359),0,Random.Range(-359, 359));
StartCoroutine(WaitAndStart(1.0));
}

function WaitAndStart (waitTime : float) 
{
yield WaitForSeconds (waitTime);
var randomDirection : Vector3 = new Vector3(Random.Range(-359, 359),0,Random.Range(-359, 359));
StartCoroutine(ChangeDirection(3.0));
}

Error is:

1)Assets/Blind_Scripts/Random_2D_Movement.js(35,16): BCE0070: Definition of 'Random_2D_Movement.WaitAndStart' depends on 'Random_2D_Movement.ChangeDirection' whose type could not be resolved because of a cycle. Explicitly declare the type of either one to break the cycle.

2)Assets/Blind_Scripts/Random_2D_Movement.js(35,15): BCE0023: No appropriate version of 'UnityEngine.MonoBehaviour.StartCoroutine' for the argument list '(unknown)' was found.

Ok, I reviewed your script just by head so try and report any error so that we can fix it.

    var speed : Vector3; 
    var timing :float;

    function Start() { 
       // I reckon you are in 2D so z is 0
       speed = Vector3(Random.Range(-359, 359),Random.Range(-359, 359),0); 
       timing = 0;
    }

    function FixedUpdate() { 
       timing+=Time.deltaTime;
       rigidbody.MovePosition(rigidbody.position + speed * Time.deltaTime); 
        if(timing > 3){
           ChangeDirection();
           timing = 0;
        }
    }

    function ChangeDirection () { 
        speed = new Vector3(Random.Range(-359, 359),0,Random.Range(-359, 359),0);  }

Thank you so much, I see now what a mess my script was) This one works perfectly!

I'm sorry, but I've got another question. Is there a way to point an object of script in the direction of movement? I can not find a way to use a current Vector3 as a looking direction, not via LookAt, not via Rotate functions...

Do you mean you can figure out LookAt()?

target:Transform; // drag your target object in the inspector

function Update(){ transform.LookAt(target); }

Or explain a little more I did not quite get what you meant.

I mean that I am trying to make the object, that I attach this script to, face in the direction of the movement. And each time the direction of movement changes, so does the facing direction. And so on...

"I wanted to create a script, that moves an object in one direction and changes the direction of the movement every three seconds." I am lost, that is what you wanted but now you don'ty want it?

var moveSpeed:float = 10;
var timing :float;
var target:Vector3;

function Start() { 
   timing = 0;
}

function FixedUpdate() { 
   timing+=Time.deltaTime;
   transform.position += transform.forward*moveSpeed*Time.deltaTime
    if(timing > 3){
       ChangeDirection();
       timing = 0;
    }
}

function ChangeDirection () { 
    target.position = Vector3(Random.Range(-359, 359),Random.Range(-359, 359),0);  }

Well , I tried to review with the information I understood, now you get a random position on the map to where the guy is heading. It changes every 3 seconds.
