Drag by touch issue "lag"

Hi all,

I use this code to move a object on the screen where my finger is moving.
It is working but it's slow "lag".
When I move my finger slowly on the screen its following but when you go just a little faster it stops following and I have to go back to the object to reselect it and start moving again.

Is there a way to do this better?

Code (csharp):

1.  
2. function Update () {
3.  
4.     for (var touch : Touch in Input.touches){
5.  
6.         var ray = Camera.main.ScreenPointToRay(touch.position);
7.  
8.         var hit : RaycastHit;
9.  
10.         if (Physics.Raycast (ray, hit, 100)) {
11.  
12.             if(touch.phase == TouchPhase.Began || touch.phase == TouchPhase.Moved) {
13.  
14.                 var cameraTransform = Camera.main.transform.InverseTransformPoint(0, 0, 0);
15.  
16.                 object.transform.position = Camera.main.ScreenToWorldPoint(new Vector3 (touch.position.x, touch.position.y, cameraTransform.z - 0.5));
17.  
18.             }
19.  
20.         }
21.  
22.     }
23. }
24.  

 

Bump!

 

As far as I know, it's a hardware/OS limitation.

 

Try function FixedUpdate instead.

 

I know this is old, but one thing I found was to include the touch . phase == stationary in your checking of which phases to do something. I have found not doing this causes the object to stutter and drop, most likely when the user's finger pauses.
