Movement on touch

Unity Engine

I’m working on a google cardboard VR game. Unlike other cardboard viewers with the magnet slide thing, my viewer (I believe it is a Homido Grab) has a button that extends a small stylus onto the screen. But despite reading a bunch of tutorials I can’t find a method to just “touch screen, go forward” I’m not interested in dragging or anything since it’s a VR thing so there can’t be dragging.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerMovement : MonoBehaviour {
    public Rigidbody rb;
    public float speed;

    // Use this for initialization
    void Start () {
        rb = GetComponent<Rigidbody> ();
    }
   
    // Update is called once per frame
    void Update () {
        if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) {
                rb.AddForce (transform.forward * speed);
            }
        else if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Ended){
                rb.velocity = Vector3.zero;
            }
        }
    }

So to recap, what I want the code to do is make me go in the direction I’m looking when I hold down the button on the headset (which just touches the screen) At the moment the code seems to do nothing. I set up the Google VR demo on my phone and the button worked just fine for that, but the code was too complex form me to understand.

Change line 16 to:

if (Input.touchCount > 0) {

It checks if the touch just started, so it’ll only add a force for one frame. You can remove the touch phase check from the next branch and just make it an else statement.
