Gameobject on Touch is showing very near to camera .

Gameobject on Touch is showing very near to camera it covers whole the screen i want that it will only drag the gameobject and would not show gameobject very near to camera

I got the answer that’s very simple only changes the Z axis position to positive value…like newposition.z = 13.0f by fixing its value it goes far away from camera and only changing x and y co-ordinates…
