Semi-Controlled Array Randomization

Questions & Answers
1

Essentially, what this javascript does is choose a random Transform from an array and moves the camera towards the transform. Then, when the camera collides with one of the Transforms, it randomly chooses a new one and moves towards it. Rinse and Repeat.

However, i am coming across an issue where the random generator will choose the new target to be the same as the old target, which causes the loop to quit itself. What do I need to do to make the old and new targets to be different each time?

//Array of Possible Camera Target Locations and Current Target
var movTargets : Transform[] = new Transform[6];

var currentTarget : Transform;

function OnTriggerEnter (Collider) {

PickRandomTarget();

}

function Update () {

transform.LookAt(target);

MoveToTarget();

}

function PickRandomTarget () {

// set currentTarget to a new target from the movTargets array

currentTarget = movTargets[Random.Range(0, movTargets.Length)];

Debug.Log(currentTarget);

}

function MoveToTarget () {

//Automatically Moves Camera to currentTarget

transform.position = Vector3.MoveTowards(transform.position, currentTarget.position, speed * Time.deltaTime);

}

I am very inexperienced with javascript (and programming languages in general), so any help provided will be greatly appreciated.

try this:

function PickRandomTarget () {

// set currentTarget to a new target from the movTargets[] array

    var newTarget : Transform;
    do
    {
       newTarget = movTargets[Random.Range(0, movTargets.Length)];
     } while((newTarget.position - currentTarget.position).sqlMagnitude < 1);
     currentTarget = newTarget;

   Debug.Log(currentTarget);
   }
