Adding FPS Sliding using the Character Controller

I'm currently working on a FPS "Speedrun" game & I want to add "Sliding" to the players movement. I already added "Crouching", but currently I'm stuck at getting the sliding done. (I'm using the Character Controller) I've tried many things, but nothing really worked. Heres the current PlayerMovement script:

It would be very nice if anyone could try to explain me how to implement it into this code using the Character Controller! :)
I've tried multiple Youtube Tutorial solutions & a lot in Online Forums, nothing really worked for me for some reason. Often the system wouldn't even work (nothing happened). I want the player to have the crouching ability (which is implemented) & to slide when isRunning & when the player isGrounded

I have been trying for a very long time to fix this, although I'm not the best at coding. I decided to come onto stack overflow for some help. Thank you to everyone who tries to solves this problem :D. As the titles states everything here works, excluding the crouching, when I press ctrl my moveSpeed does not change to my crouchSpeed...

having problems with unity transform

So, I made a basic movement script with wallrunning and wanted to add dashing to it, at first I made parameters for the character to dash and testing it with debug.log worked as intended, but the actual dash command, which was transform.translate(Vector3.forward), didn't work for some reason.
This is the code:
public class PlayerMovement : MonoBehaviour
{
public Transform player;
public CharacterController controller;
public float speed = 12f;
public float baseSpeed;
Vector3 velocity;
public float gravity = -9.81f;
public Transform groundCheck;
public float groundDistance = 0.4f;
public LayerMask groundMask;
public Transform wallCheckL;
public Transform wallCheckR;
public float wallDistanceL = -0.4f;
public float wallDistanceR = 0.4f;
public LayerMask wallMask;
public bool touchWallL;
public bool touchWallR;
public float SlideTime = 10f;
public float Ynormal;
public bool isGrounded;
public bool Sprinting;
public bool Crouching;
public bool Sliding;
public bool canDash;
// Start is called before the first frame update
void Start()
{
baseSpeed = speed;
canDash = true;
}
// Update is called once per frame
void Update()
{
isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);
touchWallL = Physics.CheckSphere(wallCheckL.position, wallDistanceL, wallMask);
touchWallR = Physics.CheckSphere(wallCheckR.position, wallDistanceR, wallMask);
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);
if ((isGrounded == true) && Input.GetKeyDown("space"))
{
velocity.y = 10f;
}
if (Input.GetKeyDown(KeyCode.LeftShift))
{
speed = baseSpeed * 1.5f;
Sprinting = true;
}
if (Input.GetKeyUp(KeyCode.LeftShift))
{
speed = baseSpeed;
Sprinting = false;
}
if (Input.GetKeyDown(KeyCode.LeftControl))
{
Crouching = true;
}
if (Input.GetKeyUp(KeyCode.LeftControl))
{
Crouching = false;
}
if (Crouching)
{
transform.localScale = new Vector3(1f, 0.5f, 1f);
} else if (Crouching == false)
{
transform.localScale = new Vector3(1f, 1f, 1f);
}
if (Sprinting && Crouching)
{
Sliding = true;
} else if (Sprinting == false && Crouching == false)
{
Sliding = false;
}
if (Sliding)
{
speed = baseSpeed * 2;
transform.localScale = new Vector3(1f, 0.25f, 1f);
}
Ynormal = transform.localEulerAngles.y;
if (touchWallL)
{
gravity = -4.4f;
transform.localRotation = Quaternion.Euler(0, Ynormal, -20f);
isGrounded = true;
} else if (touchWallR)
{
gravity = -4.4f;
transform.localRotation = Quaternion.Euler(0f, Ynormal, 20f);
isGrounded = true;
}
else
{
gravity = -9.81f;
transform.localRotation = Quaternion.Euler(0f, Ynormal, 0f);
}
if (touchWallR && Input.GetKeyDown(KeyCode.Space))
{
velocity.y = 10f;
transform.position += Vector3.left * Time.deltaTime * 100;
}
if (Input.GetKeyDown(KeyCode.E) && canDash)
{
Dash();
}
}
void Dash()
{
StartCoroutine(dashTimer());
player.transform.Translate(Vector3.forward * Time.deltaTime * speed);
}
IEnumerator dashTimer()
{
canDash = false;
yield return new WaitForSeconds(2f);
canDash = true;
}
}
The requirements themselves work, I did some testing, but the dash itself didn't. I tried controller.move, transform.position += transform.position, even making a game object empty called dash distance and trying to teleport my character there, but none of it worked, all of it resulted in my character just not doing anything when I tried to dash.

This is due that Transform.Translate actually needs to be updated each frame.
Try refactoring a bit like this:
// add another control flag
private bool isDashing = false;
void Update()
{
//...
if (Input.GetKeyDown(KeyCode.E) && canDash)
{
StartCoroutine(dashTimer());
}
if (isDashing)
{
Dash();
}
}
void Dash()
{
player.transform.Translate(Vector3.forward * Time.deltaTime * speed);
}
IEnumerator dashTimer()
{
canDash = false;
isDashing = true;
yield return new WaitForSeconds(2f);
canDash = true;
isDashing = false;
}

Why do objects stutter while I move and the camera is rotating?

I have began developing an fps script and followed a tutorial to help with the script. Everything works great now but the only issue is any objects in the view seem to stutter whenever the player is moving and rotating at the same time.
The script for the player's movement and camera rotation is below.
Can anybody point me in the right direction?
Thank you.

Cursor.lockState = CursorLockMode.Locked;
bodyRotationX += Input.GetAxis("Mouse X") * camRotationSpeed;
camRotationY += Input.GetAxis("Mouse Y") * camRotationSpeed;
camRotationY = Mathf.Clamp(camRotationY, camMinimumY, camMaximumY);
Quaternion camTargetRotation = Quaternion.Euler(-camRotationY, 0, 0);
Quaternion bodyTargetRotation = Quaternion.Euler(0, bodyRotationX, 0);
transform.rotation = Quaternion.Lerp(transform.rotation, bodyTargetRotation, Time.deltaTime * rotationSmoothSpeed);
cam.localRotation = Quaternion.Lerp(cam.localRotation, camTargetRotation, Time.deltaTime * rotationSmoothSpeed);
}
void Movement()
{
directionIntentX = cam.right;
directionIntentX.y = 0;
directionIntentX.Normalize();
directionIntentY = cam.forward;
directionIntentY.y = 0;
directionIntentY.Normalize();
rb.velocity = directionIntentY * Input.GetAxis("Vertical") * speed + directionIntentX * Input.GetAxis("Horizontal") * speed + Vector3.up * rb.velocity.y;
rb.velocity = Vector3.ClampMagnitude(rb.velocity, maxSpeed);
if (Input.GetKey(KeyCode.LeftShift))
{
speed = runSpeed;
}
if (!Input.GetKey(KeyCode.LeftShift))
{
speed = walkSpeed;
}
}
void ExtraGravity()
{
rb.AddForce(Vector3.down * extraGravity);
}
void GroundCheck()
{
RaycastHit groundHit;
grounded = Physics.Raycast(transform.position, -transform.up, out groundHit, 1.25f);
}
void Jump()
{
rb.AddForce(Vector3.up * jumpPower, ForceMode.Impulse);
}
}

This probably happens because the frame needs to update the camera rotation and the player position at the same time. i would suggest doing the rotation of the camera in fixed update. because this will run at the end of each frame.
like this:
void FixedUpdate()
{
LookRotation();
}
another thing i would suggest is to move the player while the groundcheck is being ran, because if you do it seperately i can see a bug coming up when the player moves faster then the code can run or something. so a tip would be or to run it inside the movement method, or call the method while you are calling the movement method.
this:
void Movement()
{
directionIntentX = cam.right;
directionIntentX.y = 0;
directionIntentX.Normalize();
directionIntentY = cam.forward;
directionIntentY.y = 0;
directionIntentY.Normalize();
rb.velocity = directionIntentY * Input.GetAxis("Vertical") * speed + directionIntentX * Input.GetAxis("Horizontal") * speed + Vector3.up * rb.velocity.y;
rb.velocity = Vector3.ClampMagnitude(rb.velocity, maxSpeed);
if (Input.GetKey(KeyCode.LeftShift))
{
speed = runSpeed;
}
if (!Input.GetKey(KeyCode.LeftShift))
{
speed = walkSpeed;
}
GroundCheck();
}
or litteraly copy and paste the code within your movement method.

Smooth fall in Unity - C#

I am working on a Character Controller Script and everything is working fine but the problem is that once my player starts to fall it is so sudden and jerks down. I would like the player to gradually fall down, this is my character controller script -

}
}
My character has a Rigidbody attactches which uses gravity and has X,Y,Z constraints for Rotation.
The player goes up smoothly and falls down smoothly but the transition between the two is very abrupt and sudden.
Thanks for the help. :)

Okay, so I took your code and had a play.
I think the issue was that in your Run() function, you were altering the velocity of the rigidbody which was affecting your jumping.
I've taken that stuff out and improved your script slightly and tested it. Attach this to a capsule with a rigidbody on it, with a floor underneath with a box collider on and hit space, and you should get a smooth jump.
Your new(ish) script:
using UnityEngine;
using System.Collections;

public float forwardVel = 12;
public float rotateCel = 12;

public float _initialJumpTime = 0.4f;
//[HideInInspector]
public bool isGrounded;
Quaternion targetRotation;
Rigidbody rBody;
Vector3 forwardInput, turnInput;
public bool canJump;
public Quaternion TargetRotation
{
get { return targetRotation; }
}
void Start()
{
targetRotation = transform.rotation;
if (GetComponent<Rigidbody>())
rBody = GetComponent<Rigidbody>();
else
{
Debug.LogError("Character Needs Rigidbody");
}
// forwardInput = turnInput = 0;
forwardInput = turnInput = Vector3.zero;
}
void Update()
{
GetInput();
//Turn ();
if (Input.GetKeyDown(KeyCode.Space) && canJump)
{
rBody.AddForce(Vector3.up * jumpHeight, ForceMode.Impulse);
}
}
void GetInput()
{
//forwardInput = Input.GetAxis ("Vertical");
//turnInput = Input.GetAxis ("Horizontal");
forwardInput = new Vector3(Input.GetAxis("Horizontal") * rotateCel, 0, Input.GetAxis("Vertical") * forwardVel);
forwardInput = transform.TransformDirection(forwardInput);
}
void FixedUpdate()
{
//Run();
}
void Run()
{
//HERE YOU SET THE RIGIDBODYS VELOCITY, WHICH IS CAUSING YOUR JUMP TO NOT WORK PROPERLY. DO NOT MODIFY THE VELOCITY
//OF A RIGIDBODY

Couple of points:
name your variables inThisKindOfFashion (jumpHeight, isOnGround, camelCaseExample), having variables beginning with a capital letter like Gravity and JumpHeight can get confusing.
as someone once answered on one of my questions, don't modify the velocity of a rigidbody unless you know what you are doing! Seems odd, but after following that advice I've never had a problem since!
In your script I have used OnCollision rather than OnTrigger. If you put a floor with a box collider underneath your capsule with a collider, rigidbody and this script on, your character will stop on the ground. If you use a trigger, he will fall through (at least in my experience!)
Happy coding! :-)
Edit
To respond to your comments:
"How do you suggest I move the player"
Movement can be done in a variety of different ways, but I usually use this one all the time unless I need to do something a bit differently:
void Update()
{
if (Input.GetKeyDown(KeyCode.LeftArrow))
{
transform.position += Vector3.left * speed * Time.deltaTime; //speed could be 5f, for example (f means float);
}
// then do the same for other directions, RightArrow -.right, UpArrow - .forward, DownArrow - .back
}
"How do I adjust how fast the player jumps"
You can alter the jumpHeight variable for a higher or smaller jump. If by faster you mean falls down faster, go to Edit>Project Settings>Physics> and change Y gravity to something smaller, such as -20.

They have a wide variety of tutorials, and even have ones that come with example projects so you can just put it together following the video.
