On my terrain, I set an empty child to to be a collider of it's mesh like below:

Thanks to some of the community on the Unity forms I was able to get the PlayerController to rotate/hug the slope or terrain smoothly with Racasting as it navigates, but occasionally, certain areas where you rest will jitter like below:

Here is the code for the PlayerController
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour {
public float speed = 10f;
public float runSpeed = 20f;
public float jumpForce = 7f;
public float gravity = 15f;
public bool isRunning = false;
private Vector3 moveDir = Vector3.zero;
public bool grounded;
private Vector3 turnVector;
private Vector3 posCur = Vector3.zero;
private Quaternion rotCur;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
// CharacterController reference
CharacterController controller = gameObject.GetComponent ();
//Check if character is on the ground
if( controller.isGrounded ) {
//Set new Vector3 with X,Y,Z coordinates
moveDir = new Vector3 (Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
moveDir = transform.TransformDirection (moveDir);
// Check for run input
if (Input.GetButtonDown ("Run")) {
isRunning = true;
} else if (Input.GetButtonUp ("Run")) {
isRunning = false;
}
moveDir *= speed;
// Check for jump input
if (Input.GetButtonDown ("Jump")) {
moveDir.y = jumpForce;
}
//Allign player to the terrain
Ray ray = new Ray(transform.position, -transform.up);
RaycastHit hit;
if(Physics.Raycast(ray, out hit, 1.5f) == true) {
Debug.DrawLine(transform.position, hit.point, Color.green);
rotCur = Quaternion.FromToRotation(transform.up, hit.normal) * transform.rotation;
posCur = new Vector3(transform.position.x, hit.point.y + 1f, transform.position.z);
grounded = true;
}
else {
grounded = false;
}
if(grounded == true) {
transform.rotation = Quaternion.Lerp(transform.rotation, rotCur, Time.deltaTime * 5);
}
else {
transform.position = Vector3.Lerp(transform.position, transform.position - Vector3.up * 1f, Time.deltaTime * 5);
if(transform.eulerAngles.x > 15) {
turnVector.x -= Time.deltaTime * 1000;
}
else if(transform.eulerAngles.x < 15) {
turnVector.x += Time.deltaTime * 1000;
}
rotCur.eulerAngles = Vector3.zero;
transform.rotation = Quaternion.Lerp(transform.rotation, rotCur, Time.deltaTime);
}
}
moveDir.y -= gravity * Time.deltaTime;
controller.Move (moveDir * Time.deltaTime);
}
void FixedUpdate() {
}
}
I've tried tweaking speed settings, collider size but I just can't seem to get the jitter to be gone. Any ideas what is going on?
