I am having a little trouble with moving a GameObject to a finger tap position, I dare say it is quite simple but I am very new to scripting (I’m using c# btw) and have experimented for so long that I have become a little lost… so any help would be muchly appreciated.
I have a simple scene with an uneven terrain (and a few objects) and I would like to be able to move a GameObject from it’s position to the position of the touch.
In my previous test I was able to instantiate a prefab at the touch position so I have used that script as my starting point, and I can get my GameObject to move but it moves in increments to a random position in the approximate direction of my tap… not exactly what I had in mind.
So this is my script thus far and it is attached to the GameObject I am trying to move.
using UnityEngine;
using System.Collections;
public class MoveToTap : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.touchCount > 0 Input.GetTouch(0).phase == TouchPhase.Began)
{
RaycastHit hit;
Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
if(Physics.Raycast(ray,out hit))
if(hit.collider != null)
{
transform.Translate(hit.point);
}
}
}
}
Thanks Lacost, and sorry for the slow reply (been away from the computer for a few)
I tried your suggestion but had no joy… I guess it could be a Unity Remote thing but my original code was closer to what I need. I would also prefer a Multitouch compatible solution… But thank you so very much for your help.
Just a question, is transform.Translate an incremental change or an absolute? I’m thinking that may be my problem… maybe?
Well I got it to work… I can now move a GameObject (with this C# script attached) to the touched point on any collider in my scene (phew and yay!) I think my main issue was not giving the GameObject a starting point in the transform equation… Vector3.Lerp was my hero in the end.
Just in case there are any other newbies out there having the same problem I thought I would post my solution (may not be ideal but it works thus far)
using UnityEngine;
using System.Collections;
public class MoveToTap : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
if(Input.touchCount > 0 Input.GetTouch(0).phase == TouchPhase.Began)
{
RaycastHit hit;
Ray ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
if(Physics.Raycast(ray,out hit))
if(hit.collider != null)
{
transform.position = Vector3.Lerp(transform.position,hit.point,Time.time);
}
}
}
}
