moving a gamobject in vacum

Questions & Answers
1

hi guys
i have a gameobject that moves up and down and right and left slowly , like vacum movement
this is the code ive written , it runs when the movingtime parameter is true but it doesnt work correctly because of moving time boolean is always true and it hasnt got smooth movement

function MoveInVacum()
{
	MovingTime = false ;
	NextMoveForX = Random.Range(StartPointXLeft , StartPointXRight);
	NextMoveForY = Random.Range(StartPointYDown , StartPointYUp);
	NextPoint.x =  transform.position.x ;
	NextPoint.y = NextMoveForY ;
	NextPoint.z = transform.position.z ;
	this.transform.position = Vector3.Lerp(this.transform.position,  NextPoint, .02 * Time.deltaTime);
	//print(NextMoveForX);
	//yield WaitForSeconds (1);
	MovingTime = true ;
}

so , would anyboy please correct my plan for solving this problem , thanx

I’m not quite sure what you’re actually trying to do, but I’m sure it would be far easier with coroutines in any case:

var startPointXLeft = -5.0;
var startPointXRight = 5.0;
var startPointYDown = -5.0;
var startPointYUp = 5.0;
var moveSpeed = 5.0;

function Start () {
	while (true) {
		var nextMoveForX = Random.Range(startPointXLeft, startPointXRight);
		var nextMoveForY = Random.Range(startPointYDown, startPointYUp);
		var originalPoint = transform.position;
		yield Move(Vector3(transform.position.x, nextMoveForY, transform.position.z));
		yield Move(originalPoint);
		yield Move(Vector3(nextMoveForX, transform.position.y, transform.position.z));
	}
}

function Move (nextPoint : Vector3) {
	var startPoint = transform.position;
	var rate = 1.0 / Vector3.Distance(nextPoint, startPoint) * moveSpeed;
	var t = 0.0;
	while (t < 1.0) {
		t += Time.deltaTime * rate;
		transform.position = Vector3.Lerp(startPoint, nextPoint, t);
		yield;
	}
}

Are you looking for it to slowly move back and forth and up and down? Mathf.PingPong() might be better for you to use than just getting random values
