How to translate object using script?
Hello! I have a script adapted from one my tutor gave me, which allows me to rotate and zoom on an object. The script is attached to my main camera and focused on an empty game object which is in the same position as my actual object. My question is: how do I add a functionality to allow me to move the object across the screen as well (ie. translate it on the x,y axes)? I am making an app for Android, so currently the rotate function is with one finger drag, the zoom is pinch, and I would like to be able to add this translate function so that a two finger drag moves the object. I have trawled unity answers and have found nothing and am really struggling to work out in my head how to adapt this script, so any help would be much appreciated!! Cheers.

Try this:
private void TranslateTarget(Vector2 motion)
{
target.position += transform.right * motion.x + transform.up * motion.y;
}
