Drag a cube in place

Unity Engine
1

Hey all. I am making a simple splash page for my site. I need to drag a cube in place, Mouse Orbit style, but only while clicking. So I modified the Mouse Orbit script to only work while holding the mouse down. Now my problem is that when you release the mouse button, the cube instantly halts. I want it to spin to a halt slowly. What should I do to make that happen? Thanks!

Do you want make something spin, and then slow down and stop. It would probably be something like this:

var axis : Vector3 = Vector3 (0, 1, 0); 
var spinTime : float = 5.0; 
var spinSpeed : float = 80.0; 

function Start () 
{ 
   SpinOut (); 
} 

function SpinOut () 
{ 
   var originalTime : float = Time.time; 
   var wantedSpeed : float = (originalTime + spinTime) - Time.time; 
   while (Time.time < originalTime + spinTime) 
   { 
      transform.Rotate (axis.normalized * wantedSpeed * Time.deltaTime * spinSpeed); 
      wantedSpeed = (originalTime + spinTime) - Time.time; 
      yield; 
   } 
}

Does this work for you?

Thanks for the sample code.

I too am interested in something like this, however, I think what NickAVV and I would like to accomplish is to manipulate the spinning directly when the mouse if pressed (or in my case a swipe gesture on iPhone), and then when finger (or button) is released, dampen the motion of the spinning to gradually come to a complete stop.

An additional problem is using transform.Rotate on a cube object (in my case) and getting the rotation vector for World space instead of local space.

Can anyone provide additional insight?

I’m currently looking into this.

Trying to get a cube to spin on either the X or the Y axis depending on where the user drags their mouse.
I’ve been playing a little with iTween to get the ball rolling…

function OnMouseDrag () {
    
    iTween.RotateTo(gameObject, {"x":180, "time": 2, "onComplete": "MoveBack"});
}

Would I be right in saying that with the mouse commands, it would work the same on a touchscreen too?
