touch.deltaPosition not working?

Juan · Feb 7, 2011

Eeer...forget about that, my bad, i used

Code (csharp):

val_x = Input.GetTouch(0).position.x;

instead of

Code (csharp):

val_x = Input.GetTouch(0).deltaPosition.x;

Hi, i'm having a strange problem with the touch.deltaPosition.

Instead of giving me the deltaPosition of the touch, it's giving me the same as touch.position.

Is this known or is my code?

My code is based in the one found in the help, here it is:

Code (csharp):

var tex_x : GUIText;

var tex_y : GUIText;

var infoin : GUIText;

var infonum:int = 0;

var val_x:int ;

var val_y:int ;

function Update () {

if (Input.GetTouch(0).phase == TouchPhase.Began) {

infonum = infonum + 1;

infoin.text = ""+infonum.ToString("f2");

}

if (Input.touchCount > 0 Input.GetTouch(0).phase == TouchPhase.Moved) {

var touchDeltaPosition:Vector2 = Input.GetTouch(0).deltaPosition;

val_x = Input.GetTouch(0).position.x;

val_y = Input.GetTouch(0).position.y;

tex_x.text = "" + val_x.ToString("f2");

tex_y.text ="" + val_y.ToString("f2");

}

}

I'm using three GUIText to see the changes in the screen.

Some idea?

Thanks.

likely a workaround to make multitouch usable on android at all.
Until very recently (not sure how recently, but HTC Desire for example suffers from anomalies on touch 2+ too) the multitouch implementation on android devices was limited and/or broken, leading to problems on touch 2+ handling that end with jumping around stuff and alike.

As such its not really safe to track too much on this end, EA and others omited multitouch whereever possible (sims 3 has multitouch on every platform aside android for example) to support more than Q4 2010 released android devices.
