How to program a bunch of 1st person animations at different speeds

I have made 4 different types of animation clips in an animator for an an empty gameobject called "Animator". The main camera is a child of this.
The animations feature a running cycle, a walking cycle, a crouch cycle, and an idle cycle. They all have a trigger that let's them play.
How am I able to measure the speed of the player and execute these animations when the player reaches a certain speed. I have found someone else trying to do this and it works but only for idle and walk. But unfortunately I can't get the sprint and crouch to work. I'm not sure what to do, either have the sprint and crouch animations or just change the speed of the walk animation depending on whether the player is sprinting or crouching. I'll leave a comment where the code I found is.
Here's what I have in my player controller (thge trigger stop is for the idle animation):
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController controller;
Animator _ar;
public float speed;
[Range(-5, -20)]
public float gravity = -9.81f;
public float sprintSpeed = 6f;
public float walkSpeed = 4f;
public float crouchSpeed = 2f;
public float standHeight = 1.6f;
public float crouchHeight = 1f;
Vector3 velocity;
bool isGrounded;
public Transform groundCheck;
public float groundDistance = 0.4f;
public LayerMask groundMask;
public Light _l;
//Set this to the transform you want to check
public Transform objectTransfom;
private float noMovementThreshold = 0.0001f;
private const int noMovementFrames = 1;
Vector3[] previousLocations = new Vector3[noMovementFrames];
public bool isMoving;
//Let other scripts see if the object is moving
public bool IsMoving
{
get { return isMoving; }
}
void Awake()
{
//For good measure, set the previous locations
for (int i = 0; i < previousLocations.Length; i++)
{
previousLocations[i] = Vector3.zero;
}
}
void Start()
{
_ar = GameObject.Find("Animator").GetComponentInChildren<Animator>();
}
// Update is called once per frame
void Update()
{
isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
if (isGrounded && velocity.y < 0)
{
velocity.y = -2f;
}
float x = Input.GetAxis("Horizontal");
float z = Input.GetAxis("Vertical");
Vector3 move = transform.right * x + transform.forward * z;
controller.Move(move * speed * Time.deltaTime);
velocity.y += gravity * Time.deltaTime;
controller.Move(velocity * Time.deltaTime);
//Below here is the code I found. The if statements for isMoving, is what I put in to see if
//this worked.
//Store the newest vector at the end of the list of vectors
for (int i = 0; i < previousLocations.Length - 1; i++)
{
previousLocations[i] = previousLocations[i + 1];
}
previousLocations[previousLocations.Length - 1] = objectTransfom.position;
//Check the distances between the points in your previous locations
//If for the past several updates, there are no movements smaller than the threshold,
//you can most likely assume that the object is not moving
for (int i = 0; i < previousLocations.Length - 1; i++)
{
if (Vector3.Distance(previousLocations[i], previousLocations[i + 1]) >= noMovementThreshold)
{
//The minimum movement has been detected between frames
isMoving = true;
break;
}
else
{
isMoving = false;
}
}
if(isMoving == true)
{
if (Input.GetKeyDown(KeyCode.LeftShift))
{
speed = sprintSpeed;
_ar.SetTrigger("WalkSprint");
}
else if (Input.GetKeyUp(KeyCode.LeftControl))
{
speed = crouchSpeed;
_ar.SetTrigger("WalkCrouch");
//transform.localScale = new Vector3(0.8f, 0.5f, 0.8f);
}
else
{
speed = walkSpeed;
_ar.SetTrigger("Walk");
//transform.localScale = new Vector3(0.8f, 0.85f, 0.8f);
}
}
else
{
_ar.SetTrigger("Stop");
}
}
}

Unfortunately, as with many issue in Game Dev, this could be a number of different issues (or all of them!). Here is where you can start to debug:
Check your error log to see if there is anything obvious that jumps out at you, like a bad reference to a Game Object/Componenet.
Watch the animator. You should be able to have the Animator open, side-by-side with your game window while the game is running. You should be able to see the animations running and transitioning. See if something is not linked properly, or if an animation time is configured incorrectly, etc.
Add some debug statements, like outputting the current trigger being set. I would even verify that your inputs are configured correctly. Maybe add some additional conditionals at the beginning that debug what inputs are being pressed.
As #OnionFan said, your Input check is for KeyUp for the Crouch key. That should probably be KeyDown.

(Unity C#) NPC not moving on Grass and other terrain

I have created a NPC that follows the main player. When the player is in a certain range of the NPC, the NPC is supposed to walk, run, and attack based on the distance between the player and the NPC. The NPC has an Animator, box collider, Nav Mesh Agent, Enemy Animator And Enemy Controller Script attached. The settings are as follows,
My problem is that the NPC does not chase the player if there's some sort of grass or ferns on the terrain.
The NPC is set to run all types of terrain using Nav Mesh Agent, moreover the bake settings are like in the image. A video of the issue can be seen here.
The code of the enemy controller (although I doubt that is the issue) is as follows:
using System.Collections;

I would appreciate very it if someone could help with such an issue!
EDIT: I forgot to add the grass settings, these are as follows. As you can see there are no colliders.
I am digging some more and apparently the only walkable area is as follows (not entire map), how can I adjust this?

Below is how I did:
Painted the terrain with all kinds of grasses I needed and trees.
Undone all the painted grasses and trees.
Baked the navigation mesh(Navmesh) onto the terrain.
Redone all the painted grasses and trees.
Boom! Work done. :)
Why Do grasses not walkable?
Grasses have been painted like trees hence they are carved during baking process as trees.
Trick:
You have to paint the grasses and all the trees needed, then you have to unpaint all the grasses exceptional for the trees. After that bake the terrain, and undone the process(pressing CTRL + Z several times) until you see the grasses repainted.

Unity: Animation looping while waiting for state transition

I previously posted this question on the gameDev SE but with no luck, therefore I am trying to see if I could find some help here.
I am having some troubles with the transitions in my animator. Specifically, I am trying to set up a some code to handle combo sequences, and to do so I am using coroutines that exploit the state machine given by the animations in the animator. Here is my script:
using System.Collections;

What I am doing basically is to use enums to define the player states and on input, if the player is not already in the attacking state, perform an attack. Once the FirstAttack() is called, it will first of all update an integer, comboCounter, which handles the transitions between consecutive attacks, input said integer in the animator and then change my state to attack. After this, I created a while loop that goes on until the end of an established time interval during which the player would be able to press the same attack button to chain the combo. If this does not happen, the state and integer parameter are reset.
The problem I am facing is that while the player can actually perform the combo with the second attack, during all the interval in which the first animation is active it keeps looping. Furthermore, I noticed that the second animation does not reach the end, it seems like it stops once the interval that I previously set will end.
Update: This is the screenshot of my animator window:
The transitions any state -> 1stAttack and 1stAttack -> 2ndAttack is handled by the same integer parameter, comboSequence, which is set to 0 normally, to 1 for 1stAttack and to 2 for the second one. I observed that the transition any state -> 1stAttack is triggered multiple times whenever I press the hit button, in line with the looping problem I am facing.
I have tried a couple of things, for instance using normal functions instead of a coroutine, but in this way, I do not understand why, there are problems with the enums states, also I think that in the long term this approach would be more modular and customisable. I feel like I am missing something trivial but I do not understand what and it has been some time now, so any help would be much appreciated!

Main maintain 360 rotation while toggling between VR and Normal mode

I have developed a VR game using Unity and Google VR SDK for Android. I want the game to be playable without a VR headset too. How should I implement switching from VR to Normal mode and vice versa? I want to maintain 360 rotation while in Normal Mode using the phone gyroscope. I have looked through many scripts online, but I can't find anything that would make this possible.
I have found that switching modes can be done using XRSettings.enabled = true/false (depending on the mode), but how to maintain 360 rotation while in Normal (Non VR mode)
Here is the script I wrote:
public class GyroToggleManager : MonoBehaviour {
private int flag = 0;
private Quaternion offset;
IEnumerator SwitchToVR() {
string desiredDevice = "cardboard";
XRSettings.LoadDeviceByName(desiredDevice);
yield return null;
XRSettings.enabled = true;
transform.localRotation = Quaternion.identity;
}
IEnumerator SwitchTo2D() {
Input.gyro.enabled = true;
// couldn't figure out how to find this.
offset = ;
XRSettings.LoadDeviceByName("");
yield return null;
transform.localRotation = Quaternion.identity;
}
// Use this for initialization
void Start () {
if(XRSettings.enabled == false){
Input.gyro.enabled = true;
}
}
// Update is called once per frame
void Update () {
if (XRSettings.enabled) {
return;
}
//Also tried different combinations here nothing worked.
transform.localRotation = Input.gyro.attitude ;
}
public void StartVR(){
if(XRSettings.enabled == false){
StartCoroutine (SwitchToVR ());
}
}
public void StartN(){
if(XRSettings.enabled == true){
StartCoroutine(SwitchTo2D());
}
}
}
Updated Script:
public class GyroToggleManager : MonoBehaviour {
Quaternion offset;
IEnumerator SwitchToVR() {
string desiredDevice = "cardboard";
XRSettings.LoadDeviceByName(desiredDevice);
yield return null;
XRSettings.enabled = true;
transform.rotation = Quaternion.identity;
}
IEnumerator SwitchTo2D()
{
Input.gyro.enabled = true;
//Get offset.. Subtract Camera rotation from Gyro rotation
offset = transform.rotation * Quaternion.Inverse(GyroToUnity(Input.gyro.attitude));
XRSettings.LoadDeviceByName("");
yield return null;
XRSettings.enabled = false;
}
private static Quaternion GyroToUnity(Quaternion q)
{
return new Quaternion(q.x, q.y, -q.z, -q.w);
}
// Use this for initialization
void Start () {
if(XRSettings.enabled == false){
Input.gyro.enabled = true;
}
}
void Update()
{
if (XRSettings.enabled)
{
return;
}
//Add the gyro value with the offset then apply to the camera
transform.rotation = offset * GyroToUnity(Input.gyro.attitude);
}
public void StartVR(){
if(XRSettings.enabled == false){
StartCoroutine (SwitchToVR ());
}
}
public void StartN(){
if(XRSettings.enabled == true){
StartCoroutine(SwitchTo2D());
}
}
}

Below is a simple camera follow script that follows a player ball while maintaining the offset distance between the camera and the player. It uses an offset value to do that by subtracting the camera's position from the player's position and then re-applying that offset to the camera's position with current player position in the Update or LateUpdate function.
public Transform playerTransform;
public Transform mainCameraTransform = null;
private Vector3 cameraOffset = Vector3.zero;
void Start()
{
mainCameraTransform = Camera.main.transform;
//Get camera-player Transform Offset that will be used to move the camera
cameraOffset = mainCameraTransform.position - playerTransform.position;
}
void LateUpdate()
{
//Move the camera to the position of the playerTransform with the offset that was saved in the beginning
mainCameraTransform.position = playerTransform.position + cameraOffset;
}
The example and code above is not exactly your solution but it's the easiest way to understand what you need to do.
In your case you need to subtract the camera's rotation from the gyro sensor or Input.gyro.attitude. The minor changes is that you can't really use - or + for that since both are Quaternion not Vector3 as in the example above.
To subtract a Quaternion from another Quaternion like I did in the
Start function with Vector3, multiply the inverse of the other
Quaternion. The inverse is
obtained with Quaternion.Inverse.
To add two Quaternions like I did in the LateUpdate function
above with Vector3, simply multiply both Quaternion together.
Here is the relevant changes in your code:
Quaternion offset;
IEnumerator SwitchTo2D()
{
Input.gyro.enabled = true;
//Get offset.. Subtract Camera rotation from Gyro rotation
offset = transform.rotation * Quaternion.Inverse(GyroToUnity(Input.gyro.attitude));
XRSettings.LoadDeviceByName("");
yield return null;
}
// Update is called once per frame
void Update()
{
if (XRSettings.enabled)
{
return;
}
//Add the gyro value with the offset then apply to the camera
transform.rotation = offset * GyroToUnity(Input.gyro.attitude);
}
private static Quaternion GyroToUnity(Quaternion q)
{
return new Quaternion(q.x, q.y, -q.z, -q.w);
}
The GyroToUnity function is used to convert the gyroscope coordinate into Unity's coordinate before applying it to the camera. The gyroscope sensor is using the right-handed coordinate while Unity's camera and other objects are using the left-handed coordinate. See this for more information.

Any way of moving my player other then the controller script teleports

I'm trying to make a spring wall in my 2d platformer. However every way I've tried to move my character (addforce, transform.translate and even tried using the bouncy naterial) teleports my character rather then moving it. This doesn't happen with my controller script. I suspect something in my script is causing this interaction but I'm not sure exactly what. Here is my controller script. Any suggestions would be greatly appreciated :))

//load the local scale
Vector3 theScale = transform.localScale;
//flip character on the x axis
theScale.x *= -1;
//and then apply it to the local scale
transform.localScale = theScale;
}
Edit
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class boost : MonoBehaviour {
private Rigidbody2D rb2d;
// Use this for initialization
void OnCollisionEnter2D(Collision2D other){
if (other.gameObject.tag == "booster") {
Vector2 tempvect = new Vector2 (2, 0);
rb2d.MovePosition ((Vector2)transform.position + tempvect);
}
}
void Start () {
rb2d = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update () {
}
}
This is the code that I think should make it work the error comes at
rb2d.MovePosition ((Vector2)transform.position + tempvect);
