3d wall jumping with charter controller

Question

im making a 3d Platformer with unity's built-in charter controller and no mater what I try I can't seem to get wall jumping right. The player jumps but he doesn't jump off the wall to the opposite side he just stays on the wall. NOTE: this is not the entire script because the script is too long to include it all so I only included the parts that involve the wall jump. This is what I have:

 void OnControllerColliderHit(ControllerColliderHit hit)
     {
         hitNormal = hit.normal;
     }

 void WallJump()
     {
         velocity.y = Mathf.Sqrt(maxJumpHight * -2 * gravity);
         animator.SetBool("Jumping", true);
         wallJumping = true;
         woosh1.Play();
         jump.Play();
         movingPlatform.enabled = false;
         canMove = false;
         StartCoroutine(CanMoveAgain());
     }

 float horizontal = moveing.x;
         float vertical = moveing.y;
         Vector3 direction = new Vector3(horizontal, 0f, vertical).normalized;
         
 
         if (direction.magnitude >= 0.1f && canMove)
         {
             if (wallJumping == true)
             {
                 direction = -hitNormal;
                 controller.Move(hitNormal * speed * Time.deltaTime);
             }
             if (!wallJumping == true)
             {
 
 
 
                 float targetAngle = Mathf.Atan2(-direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;
                 float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, turnSmoothTime);
                 transform.rotation = Quaternion.Euler(0f, angle, 0f);
 
                 Vector3 moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
                 controller.Move(moveDir.normalized * speed * Time.deltaTime);
             }
         }

it just doesn't work what do I do?

Edit: Think I found your problem. In WallJump you do:

canMove = false;

but then your code to move in the direction of the wall normal is inside this if statement:

if (direction.magnitude >= 0.1f && canMove)

which requires canMove to be true. You either need to change the if statement, move the wall jump code outside of it, or not set canMove to false.

Old wrong answer:

I see you've written a "WallJump" method which looks fine, but I dont see you actually calling it anywhere. Is there some code you haven't included where you trigger your wall jump to happen? If not I think you just forgot to do that. Somewhere when you detect if the player is against a wall and trying to jump you need to have the line:

  WallJump();

no its there I just didn't put the whole script

I imagine your problem is in that section of code, so if you don't include it I can't really help.

I know it's not the problem cuz I jump but I don't jump off the wall but here:

getting the input:

 private void Awake()

 {
     controls = new PlayerControls();

 controls.GamePlay.Jump.performed += ctx => Jumping();

 controls.Extra$$anonymous$$ovement.GroundPound.performed += ctx => TriggerButton();

 controls.Extra$$anonymous$$ovement.GroundPound.canceled += ctx => TriggerButtonCanceled();

}

checking if I can jump:

 void Jumping()
     {
         var hitAngle = Vector3.Angle(Vector3.up, hitNormal);
 
         if (isGrounded && canWalkOnSlope)
         {
             Jump();
         }
         else if (isGrounded && !canWalkOnSlope && hitAngle >= 71 && hitAngle <= 110)
         {
             WallJump();
         }
     }

and jumping:

 void WallJump()
     {
         velocity.y = $$anonymous$$athf.Sqrt(maxJumpHight * -2 * gravity);
         animator.SetBool("Jumping", true);
         wallJumping = true;
         woosh1.Play();
         jump.Play();
         movingPlatform.enabled = false;
         can$$anonymous$$ove = false;
         StartCoroutine(Can$$anonymous$$oveAgain());
     }
