Adding FPS Sliding using the Character Controller - c#

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

In Unity 3D my character's left foot does not react properly when walking, it looks wobbly when I walk around,any ideas?

The main character from the Unity 3D tutorials that I followed, I believe not from the site, are producing a wobbly left foot. I did not put a foot IK because the issue is not placement. It seems like an origin point thing, but not sure so I turned here for help.
I tried to have the full range of motion of the Mecanim character but was unable to produce foot bones on the rig that seem to work even though I just imported the model and code.

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...

Unity moving after wall running

I have coded the unity movement for my character. I made it so they can wall run bit it seems that wall running is somehow making my character walk weird. After wall running (if I wall run with the wall on my right) it will apply a force 90 degrees when I'm walking on the ground. The unknown force changes when each button is pressed (is W then apply both the W force and a force pushing it to the right). And the same happens with running on the left wall but it is at a -90 degree angle. Please help I've been stuck on this for a whole week. Thanks

Thank you soooooooo much for any help

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;
}

Wall jumping height decreases with each jump

Solved - I ended up removing playerController.SimpleMove and having playerController.Move control all the player's movement.
So I have been trying to make my character wall jump between to walls. I've been able to make it work however, after each successful wall jump the height of the next jump decreases. This gets to the point where it starts wall jumping downwards. I have no idea why it does this. Before each time pressing the space bar, I am resetting the movement Vector3's to zero and then reapplying the correct values to the jump. I have even gone through the console to look at the vertical changes and neither moveDirection and moveAmount get a large enough value change to make this happen.
Because I am just trying this out, below is all the code that is affecting the player.

transform.Rotate(0, Input.GetAxis("Horizontal") * rotateSpeed, 0);
if (onWall)
{
playerAnimator.SetBool("Wall Holding", true);

The simplest explanation is that transform.forward and/or transform.up vectors begin to diverge from your expectations over time. This would explain how it even seems to be jumping "backwards" eventually when you apply the lines below. Are you sure these vectors are oriented as you expect after the jumper collides with a wall (prior to the next jump)?
moveDirection += transform.forward * jumpSpeed * 2f;
moveDirection += transform.up * jumpSpeed * 2f;
