bug in z axis

this movement.cover

             direc = new Vector3(horizontal, 0, 0).normalized;
             direc = transform.TransformDirection(direc);
             ch.Move(direc* Time.deltaTime * speed);
             anim.SetFloat("Horizontal", horizontal);

this is my move code only in x axis but also increase or decrease in z axis–z should stay constant

             debug.log(direc); ======>(1.0,0,0.1)  gets an error because of the value at the end(0.1)
                                                           (1.0,0,0.4)

this movement.directional,Could it be because of the turn here?

            float targetAngle = Mathf.Atan2(direction.x, direction.z) * Mathf.Rad2Deg + cam.eulerAngles.y;

            transform.eulerAngles = Vector3.up * Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref tpain, rpain);

            moveDir = Quaternion.Euler(0f, targetAngle, 0f) * Vector3.forward;
            ch.Move(moveDir * speed *Time.deltaTime);

You have to to put an f at the end of a floating point. .01 will cause an error must be .01f
