Script for a gentle 'bobbing' motion, similar to thrusters trying to remain at stationary position in mid-air

Try creating two positions on the Y axis, and then moving between them smoothly. Here is a simple example I can give you, experiment around and modify it how you wish. Just to test, attach this script to a sphere in your scene, and it should "hover".

 var pos1 : Vector3;

var pos2 : Vector3;

var offset : Vector3;

var moveSpeed : float = 0.05;

var moveTo;

function Start()

{

 offset = Vector3.down;

 pos1 = transform.position;

 pos2 = transform.position + offset; 

}

function Update()

{

 if(transform.position == pos1)

 {

     moveTo = pos2;

 }

 if(transform.position == pos2)

 {

     moveTo = pos1;

 }

 

 transform.position = Vector3.MoveTowards(transform.position, moveTo, moveSpeed);

}

That worked beautifully thank you! I needed it for my hover board script haha. Now my question is, how do I change the distance it "bobs" at? I only want it to happen slightly.
