"Hover" object up and down

Questions & Answers

Hello, Is it possible to make a script that smoothly moves an object up and after a few seconds down again?

Thanks, Andreas.

A really quick and dirty way to achieve this would be to just move the objects y axis along a sine curve. I.e.:

        var Step : float; //A variable we increment
        var Offset : float; //How far to offset the object upwards
        
        function Start () {
        //Store where we were placed in the editor
        var InitialPosition = transform.position;
        //Create an offset based on our height
        Offset = transform.position.y + transform.localScale.y;
        }
        
        function FixedUpdate () {
        
        Step +=0.01;
          //Make sure Steps value never gets too out of hand 
          if(Step > 999999){Step = 1;}

          //Float up and down along the y axis, 
          transform.position.y = Mathf.Sin(Step)+Offset;
        }

Easier than iTween (Not that is particularly hard …), there is still Mathf.Lerp / Vector3.Lerp.

Oh, and checkout that link if you want to continue with iTween : http://wiki.unity3d.com/index.php?title=ITweenX
