Unity3D go down on slopes with a animated character

I'm developping a 3D game Unity with a squirrel as the player.
I'm struggling with a problem of slopes. I know, there are a bunch of tutorial to go down a slope whithout 'floating in the air while walking' but I didn't find a fine solution. I think it's because of the horizontal animations of the squirrel (maybe). I have tried with addForce, with a modified speed, with gravity... (maybe I implemented it wrong). I know I can check if I'm in the air or not with CharacterController.isGrounded but I can't force the squirrel to stick on the slope while running or walking. I'm sorry by advance if my question is too vague or simple.
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using System;
public class Squirrel : MonoBehaviour {
Animator squirrel;
public float gravity = 1.0f;
private Vector3 moveDirection = Vector3.zero;
float axisH, axisV;
public static int munitions = 0;
Rigidbody rb;
[SerializeField]
float walkSpeed = 2f, runSpeed = 8f, rotSpeed = 100f, jumpForce = 350;
private bool isJumpKeyDown = false;
[SerializeField] bool isJumping = false;
Animator characterAnimator;
int JumpCount = 0;
public int MaxJumps = 1; //Maximum amount of jumps (i.e. 2 for double jumps)
[SerializeField] GameObject nb_munitions;
CharacterController characterController;
// Use this for initialization
void Start () {
munitions = 0;
squirrel = GetComponent<Animator>();
rb = GetComponentInChildren<Rigidbody>();
characterAnimator = GetComponent<Animator>();
JumpCount = MaxJumps;
characterController = GetComponent<CharacterController>();
}
// Update is called once per frame
void Update()
{
GetInput();
nb_munitions.GetComponent<Text>().text = "Glands : " + munitions; //Affichage du score
Move();
}
private void FixedUpdate()
{
if (isJumpKeyDown)
{
squirrel.SetTrigger("jump");
JumpCount -= 1;
isJumpKeyDown = false;
}
}
public void GetInput()
{
axisV = Input.GetAxis("Vertical");
axisH = Input.GetAxis("Horizontal");
}
private void Move()
{
if (characterController.isGrounded)
{
//On the ground
}
else
{
//on the air
}
if (axisV > 0)
{
if (Input.GetKeyDown(KeyCode.LeftControl))
{
transform.position += Vector3.forward * walkSpeed * Time.deltaTime;
squirrel.SetBool("walk", true);
}
else
{
transform.position += Vector3.forward * runSpeed * Time.deltaTime;
squirrel.SetFloat("run", axisV);
squirrel.SetBool("walk", false);
}
}
else
{
squirrel.SetFloat("run", 0);
}
if (axisH != 0 && axisV == 0)
{
squirrel.SetFloat("h", axisH);
}
else
{
squirrel.SetFloat("h", 0);
}
if (axisH != 0)
{
transform.Rotate(Vector3.up * rotSpeed * Time.deltaTime * axisH);
}
if (Input.GetKeyDown(KeyCode.Space))
{
if (JumpCount > 0)
{
isJumpKeyDown = true;
}
}
//Call munitions
if (Input.GetKeyDown(KeyCode.LeftShift))
{
if (Squirrel.munitions > 0)
{
SpawnerScript.Instance.NewSpawnRequest();
munitions--;
}
}
}
}

You can try to get the angle of the slope and make it the pitch for the mesh of the squirrel.

I finally found the problem. My C# script "overwrited" the CharacterController and did not allow the squirrel to go down the slopes. Make sure you follow a move script that "respects" the CharacterController (if you pick one or you'll be fighting windmills).

Unity - how to make an object face the direction of its movement?

I'm trying to make a character prefab face the direction in which its moving. I've tired all sorts of things, with and without rigidbodies but nothing seems to work. The thing is, it does actually face in the correct direction. But once its there, it starts to rotate the whole prefab and it goes down into the ground.
The character holds a 3D shield, and goes towards a tower. So once it reaches the tower it raises the shield which in turn rotates the whole character down into the ground. I would like it to just rotate in the X and Z axis and never change the Y axis.
Here's my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class BlockRadar : MonoBehaviour
{
// Start is called before the first frame update
public Transform Tower;
private GameObject[] multipleBlocks;
public Transform closestBlock;
public bool blockContact;
public float currentDistance;
public float stopDistance;
public Animator animator;
public int damage;
public float attackspeed;
private float canAttack;
public float moveSpeed = 5f;
public Vector3 distance;
private Vector3 movement;
void Start()
{
closestBlock = null;
blockContact = false;
}
// Update is called once per frame
void Update()
{
Vector3 pos = transform.position;
pos.y = 0;
pos.x = 0;
transform.position = pos;
closestBlock = getClosestBlock();
closestBlock.gameObject.GetComponent<Renderer>().material.color = new Color(1, 0.7f, 0, 1);
Vector3 direction = closestBlock.position - transform.position;
direction.Normalize();
movement = direction;
float dist = Vector3.Distance(closestBlock.position, transform.position);
if (dist <= 1.5f)
{
{
blockContact = true;
animator.SetBool("Moving", false);
Debug.Log("Now touching block");
if (attackspeed <= canAttack)
{
Attack();
canAttack = 0f;
}
else
{
canAttack += Time.deltaTime;
}
}
}
if (dist > 1.5f)
{
transform.forward = movement;
blockContact = false;
Debug.Log("Lost contact with block");
animator.SetBool("Moving", true);
moveCharacter(movement);
}
}
public void Attack()
{
Debug.Log("ATTACKING!");
Damage(closestBlock.transform);
animator.SetTrigger("Attacking");
}
private void FixedUpdate()
{
}
void moveCharacter(Vector3 direction)
{
transform.Translate(direction * moveSpeed * Time.deltaTime, Space.World);
}
void DistanceToTower()
{
if (Tower)
{
float dist = Vector3.Distance(Tower.position, transform.position);
if (dist <= 1)
{
{
blockContact = true;
Debug.Log("Now touching block");
if (attackspeed <= canAttack)
{
Attack();
canAttack = 0f;
}
else
{
canAttack += Time.deltaTime;
}
}
}
}
}
//when the object carrying this script is destroyed
private void OnDestroy()
{
if (closestBlock !=null)
{
closestBlock.gameObject.GetComponent<Renderer>().material.color = new Color(0, 0, 0, 0);
}
}
public Transform getClosestBlock()
{
multipleBlocks = GameObject.FindGameObjectsWithTag("Block");
float closestDistance = Mathf.Infinity;
Transform trans = null;
//finds all blocks in the scene
foreach (GameObject go in multipleBlocks)
{
currentDistance = Vector3.Distance(transform.position, go.transform.position);
if (currentDistance < closestDistance)
{
closestDistance = currentDistance;
trans = go.transform;
}
}
return trans;
}
void Damage(Transform block)
{
Tower_Stats e = block.GetComponent<Tower_Stats>();
if (e != null)
{
e.TakeDamage(damage);
}
}
}
I would be really, really grateful for any help. As I said before I used to have rigidbodies on the character, but I removed them since I thought maybe they were the fault. But doesnt seem like it. One other thing I've noticed is that when the prefab is instantiated, its children doesnt have the correct position values. Not sure why. But if that could be a clue I just thought I'd let you know.

MissingReferenceException Error Occurs with Unity's New Input System when using "buttonEast / rightButton"

I'm getting this error in Unity after pressing the relative "eastButton":
Error: MissingReferenceException while executing 'canceled' callbacks of 'Gameplay/Block[/DualShock4GamepadHID/buttonEast,/Mouse/rightButton]'
UnityEngine.InputSystem.InputActionAsset:OnDestroy () (at Library/PackageCache/com.unity.inputsystem#1.0.2/InputSystem/Actions/InputActionAsset.cs:794)
I'm attempting to set up 'block' functionality within my game which simply locks the player's movement then disables my "canBeHit" bool which will then put the player in a state where they cannot be hit, however upon interacting with the eastButton all player movement is completely locked preventing you from moving, however rotation is still possible. Another part I'd like to note is that I'm working with the Mirror package so I can network my game, unsure if this could also be causing problems. Would really appreciate if someone could point out where I've gone wrong, I'd be very grateful.

How can I make the NPC move only vertical and horizontal and not diagonal with Vector2/3.MoveTowards and how can I make the NPC move only by tile

So I was trying to make a game just for fun and to learn for future use. So I encountered this problem in making the enemy NPC. I want it to follow me or chase me but I want the NPC to only move horizontal and vertical and I want the NPC to move per tile as well just like my Player.
Here's the video of how it looks
https://www.youtube.com/watch?v=CB_vdt1Z3nA
and here's the NPC script
public class ChaseScript : MonoBehaviour
{
public float speed;
private GameObject player;
private Transform player_transform;
void Start()
{
player = GameObject.Find("Player");
}
void Update()
{
player_transform = player.GetComponent<Transform>();
transform.position = Vector3.MoveTowards(transform.position, player_transform.position, speed * Time.deltaTime);
}
}
Here's my player controller
public void InputMove()
{
if (!isMoving)
{
input.x = Input.GetAxisRaw("Horizontal");
input.y = Input.GetAxisRaw("Vertical");
if (input.x != 0) input.y = 0;
if (input != Vector2.zero)
{
playerAnimation.SetParameterValue(animator);
var movePos = transform.position;
movePos.x += input.x;
movePos.y += input.y;
FacingForward.transform.position = movePos;
if (IsWalkable(movePos))
StartCoroutine(Move(movePos));
}
playerAnimation.SetParameterValueisMoving(animator);
}
if (Input.GetKey(KeyCode.LeftShift))
{
moveSpeed = 6f;
animator.speed = 1.5f;
}
else
{
moveSpeed = 4f;
animator.speed = 1f;
}
}
IEnumerator Move(Vector3 movePos)
{
isMoving = true;
while ((movePos - transform.position).sqrMagnitude > Mathf.Epsilon)
{
transform.position = Vector3.MoveTowards(transform.position, movePos, moveSpeed * Time.deltaTime);
yield return null;
}
transform.position = movePos;
isMoving = false;
}
private bool IsWalkable(Vector3 movePos)
{
if (Physics2D.OverlapCircle(movePos, 0.1f, SolidObjectLayer | NPC) != null)
{
return false;
}
return true;
}
What I did to my Player to move per tile is I just add 1 to transform so It'll be a constant movement but I don't know how to apply it on the NPC with the Vector3.MoveTowards but if it's not possible to do then it's fine

Check if this could work (you can adapt it to your 2D case)
using UnityEngine;
public class ChaseOrthoScript : MonoBehaviour
{
public float speed;
private GameObject player;
private Transform player_transform;
bool isMoving = false;
void Start()
{
player = GameObject.Find("Player");
player_transform = player.GetComponent<Transform>();
transform.LookAt(player_transform.position);
}
void Update()
{
if (transform.InverseTransformPoint(player_transform.position).z > 0) {
transform.position += transform.forward * speed * Time.deltaTime;
isMoving = true;
} else {
if (isMoving) {
float angle = Vector3.Angle(transform.forward, player_transform.position - transform.position);
transform.Rotate(Vector3.up, Mathf.Sign(angle) * 90);
isMoving = false;
} else if (transform.InverseTransformPoint(player_transform.position).z <= 0) { //player is back
transform.Rotate(Vector3.up, 180);
}
}
}
}
note that the player_transform = player.GetComponent<Transform>(); is moved to the Start(). Usually you dont want GetComponents in an update as you need to get it only once. ALso its much cleaner to have a public GameObject player; variable in the script and attach the reference in the editor that the player = GameObject.Find("Player");. Usually you dont want scene elements found by a hardcoded magic value in your code.
Hope that helps.

Why when the camera is child of the character only when pressing on W to move forward the character is not moving and everything is stuttering?

This is the character settings and components :
The character don't move and everything stuttering only when the Camera is child of the character.
If the camera is not child of the character the character will move fine but I want the camera to follow the character.
Maybe I should edit and add the ThirdPersonCharacter script ? It's attached to the character. The script is a bit long.
There are 3 scripts they are all connected a bit long but they are all making the character controlling.

In the script ThirdPersonCharacter there is no Update function at all.
In the AICharacterControl there is Update I tried to change it to FixedUpdate but it didn't fix the problem.
In the script ThirdPersonUserControl there is Update but it's only for Jump and there is also FixedUpdate so I didn't try to change anything in that script.

Try using FixedUpdate() instead of Update() and see. Also, you should at least post the relevant bit of code.
