Stop player movement if it's Raycast hits an object

I have the debug for my raycasting, and it all seems to work as intended. Now all I need is for the Player to stop moving forward if the Raycast hits another object.

Can I get examples or links to the Script References that can help me do this?

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovement : MonoBehaviour 
 {
     public PlayerCollision pCollision;
     
     public float speed = 10.0f;
     public float jumpSpeed = 10.0f;
     public float gravity = 20.0f;
     public float JPSpeed = 10.0f;
     public Vector3 moveDirection = Vector3.zero;
     public Vector3 jumpDirection = Vector3.zero;
     
     // Use this for initialization
     void Start () 
     {
         
     }
     
     void Jumping()
     {
         CharacterController playerControl = GetComponent<CharacterController>();
         
         jumpDirection = new Vector3(Input.GetAxis("Horizontal"),0.0f,0.0f);
         jumpDirection = transform.TransformDirection(jumpDirection);
         jumpDirection *= speed;
         playerControl.Move (jumpDirection * Time.deltaTime);
         
     }
     // Update is called once per frame
     void Update () 
     {
         //PlayerCollisionCheck Bools
         bool canMoveRight = pCollision.pbRight;
         bool canMoveLeft = pCollision.pbLeft;
         
         CharacterController playerControl = GetComponent<CharacterController>();
         if (playerControl.isGrounded)
         {
                     //Putting this here
                     if (!canMoveLeft || !canMoveRight)
         return;
                    //Kind of gets what I want. But dissallows left and right movement.

             if (Input.GetKeyDown(KeyCode.D) && canMoveRight)
                 {
                     moveDirection = new Vector3(1.0f,0.0f,0.0f);
                     moveDirection *= speed;
                 }
             if (Input.GetKeyUp(KeyCode.D))
             {
                 moveDirection = new Vector3(0.0f,0.0f,0.0f);
             }
         
             if (Input.GetKeyDown(KeyCode.A) && canMoveLeft)
             {
                 moveDirection = new Vector3(-1.0f,0.0f,0.0f);
                 moveDirection *= speed;
             }
             if (Input.GetKeyUp(KeyCode.A))
             {
                 moveDirection = new Vector3(0.0f,0.0f,0.0f);
             }
             if(Input.GetButtonDown("Jump"))
             {
                 moveDirection.y = jumpSpeed;
             }
         }
         moveDirection.y -= gravity * Time.deltaTime;
         Jumping();
         playerControl.Move (moveDirection * Time.deltaTime);
                 
     }
 }

Okay worse problem: Even though canMoveRight is true, it still doesn't allow me to move right. Probably because of that return;, but if I don't use return, the player is allowed to continue on.

Note: This is a small test for things I want to do that might need something like this later. So I could just use the Unity Collisions but there are things that Raycast can do better.
