transform does not exist in the current context

Question

Just keeping on convert from js to C# the code from Unity, in this script, I'm stuck with the "transform" name.

 using UnityEngine;
 using System.Collections.Generic;
 using System.Collections;
 
 [RequireComponent(typeof(Rigidbody))]
 
 public class FreeMovementMotor : MovementMotor {
     Rigidbody charRigidbody;
     public float walkingSpeed = 5.0f;
     public float walkingSnappyness = 50;
     public float turningSmoothing = 0.3f;
 
     public void Start ()
     {
        // charRigidbody = GetComponent<Rigidbody>();
         
     }
     public void FixedUpdate ()
     {
         //Handle character's movement
         Vector3 targetVelocity = movementDirection * walkingSpeed;
         Vector3 deltaVelocity = targetVelocity - charRigidbody.velocity;
 
         if(charRigidbody.useGravity)
         {
             deltaVelocity.y = 0;
         }
         charRigidbody.AddForce (deltaVelocity * walkingSnappyness, ForceMode.Acceleration);
 
         //Setup player to face facingDirection, or if that's zero, then the movementDirection
         Vector3 faceDir = facingDirection;
 
         if(faceDir == Vector3.zero)
         {
             faceDir = facingDirection;
         }
 
         //Make the character rotate towards the target rotation
         if(faceDir == Vector3.zero)
         {
             charRigidbody.angularVelocity = Vector3.zero;
         }
         else
         {
             float rotationAngle = AngleAroundAxis (transform.forward, faceDir, Vector3.up);
             charRigidbody.angularVelocity = (Vector3.up * rotationAngle * turningSmoothing);
         }
     }
 
     //The angle between dirA and dirB aorund axis
     public static float AngleAroundAxis (Vector3 dirA, Vector3 dirB, Vector3 axis) //CANT BE A VOID!! float??
     {
         //Project A and B onto the plane orthogonal target axis
         dirA = dirA - Vector3.Project (dirA, axis);
         dirB = dirB - Vector3.Project (dirB, axis);
 
         //Find positive angle between A and B
         float angle = Vector3.Angle (dirA, dirB);
 
         //Return angle multiplied with 1 or -1
         return angle * (Vector3.Dot (axis, Vector3.Cross (dirA, dirB)) < 0 ? -1 : 1);
     }
 }

in line 45

 float rotationAngle = AngleAroundAxis (transform.forward, faceDir, Vector3.up);

it says "the name "transform" does not exist in the current context [Assembly-CSharp]" Is any way to solve this? Or any advice of why I'm getting this?

Are your classes or base classes extending Monobehaviour?

No it wasn't extending $$anonymous$$onoBehaviour

 using System;
 using UnityEngine;
 using System.Collections.Generic;
 using System.Collections;
 
 public class $$anonymous$$ovement$$anonymous$$otor
 {
     /*
 This class can be used like an interface.
 Inherit from it to define your own movement motor that can control
 the movement of characters, enemies, or other entities.
 */
 
 // The direction the character wants to move in, in world space.
 // The vector should have a length between 0 and 1.
     public Vector3 movementDirection;
 
 // Simpler motors might want to drive movement based on a target purely    
     public Vector3 movementTarget;
 
 // The direction the character wants to face towards, in world space.    
     public Vector3 facingDirection;
     
 }

in .JS it was like this:

 #pragma strict
 
 /*
 This class can be used like an interface.
 Inherit from it to define your own movement motor that can control
 the movement of characters, enemies, or other entities.
 */
 
 // The direction the character wants to move in, in world space.
 // The vector should have a length between 0 and 1.
 @HideInInspector
 public var movementDirection : Vector3;
 
 // Simpler motors might want to drive movement based on a target purely
 @HideInInspector
 public var movementTarget : Vector3;
 
 // The direction the character wants to face towards, in world space.
 @HideInInspector
 public var facingDirection : Vector3;

So I didn't add "$$anonymous$$ovement$$anonymous$$otor : $$anonymous$$onoBehaviour". I just add it after reading your answer, and it seems to work, thank you!
