Google Cardboard look walk

Hi guys,
I’m (kind of) new to unity, I hope you can help me out here. I’m making a VR project and am trying to install Look Walk for Google cardboard. I have the Google VR asset pack and did about 5 tutorials on how to look walk. The tutorial that worked for me still only allowed me to look around with my pointer (holding alt), but when I look forward I don’t move forward. When I look down, I fall through my terrain. I already turned off gravity on my player, and afterward rigid body, but the same thing keeps happening and I have no idea how to fix it.
I hope you guys have any solutions for look walk!

My script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class vrlookwalk : MonoBehaviour
{
public Transform vrCamera;
public float toggleAngle = 30.0f;
public float speed = 3.0f;
public bool moveForward;
private CharacterController cc;
// Use this for initialization
void Start()
{
cc = GetComponent();
}
// Update is called once per frame
void Update()
{
if (vrCamera.eulerAngles.x >= toggleAngle && vrCamera.eulerAngles.x < 90.0f)
{
moveForward = true;
}
else
{
moveForward = false;
}
if (moveForward)
{
Vector3 forward = vrCamera.TransformDirection(Vector3.forward);
cc.SimpleMove(forward * speed);
}
}
}

Thanks!

I am having the same problem and also have not yet found a way to solve it.
I know almost a year has passed since this question was posted, but I was wondering if you (or anyone else) have found a solution in the meantime.
Let me know and thanks in advance!
