Wall Jump Scripting Help

Question

alt text Hi, Im trying to make a simple fast paced 3D plat former to learn the basics of unity. I wish to implement a wall jump that is relative to the surface the player is standing on so i dont have to create many diffrent implementations of what the player is standing on. This is my script so far...

 using System.Collections;
 
 using System.Collections.Generic;
 
 using UnityEngine;
 
 public class PlayerController : MonoBehaviour
 
 {
 
     public float speed;
     public float jump = 20f;
     private Rigidbody rb;
     float timer = 0.0f;
     bool isGrounded = true;
    
 
     void Start()
     {
         rb = GetComponent<Rigidbody>();
     }
 
  
 
 
     private void Update()
     {
         bool player_jump = Input.GetButtonDown("Jump");
 
         if (player_jump && isGrounded)
         {
             rb.AddForce(Vector3.up * jump);
         }
     }
 
 
 
 
     void OnCollisionEnter(Collision collision)
     {
         if (collision.gameObject.CompareTag("Ground"))
         {
             isGrounded = true;            
         }
         if (collision.gameObject.CompareTag("Wall"))
         {
             isGrounded = true;
         }
 
     }
 
 
 
 
     void OnCollisionExit(Collision collision)
     {
         if (collision.gameObject.CompareTag("Ground"))
         {
             isGrounded = false;
         }
         if (collision.gameObject.CompareTag("Wall"))
         {
             isGrounded = false;
         }
     }




 void FixedUpdate()
 {
     float moveHorizontal = Input.GetAxis("Horizontal");
     float moveVertical = Input.GetAxis("Vertical");

     Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

     rb.AddForce(movement * speed);
 }

}

So, My player is a ball and i wish to have it able to wall jump off of a wall. For now it jumps only up and i want to be able to grate a jump that applies a force off the wall. Like in Mario. So how do i create a wall jump that is relative to the surface that the player is standing on?

hello there, i was asking about this from 2 days too no one replied, now what i did in my project that i used OnCollisionEnter and add two force one in the direction of wall normal and one in the upward direction it worked, but it has some bugs too since no one replying about wall jumping i thought i should tell you what solution in found

NOTE IT IS NOT PREFECT HAS BUGS

  void OnCollisionEnter(Collision collision)
         {
             foreach (ContactPoint contact in collision.contacts)
             {
                 if (!IsGrounded && contact.normal.y < 0.1f)
                 {
                     Debug.DrawRay(contact.point, contact.normal, Color.yellow, 5f);
                     if (walljump == true)
                     {
                         characterControl.RIGIDBODY.AddForce(contact.normal * 6f, ForceMode.Impulse);
                         characterControl.RIGIDBODY.AddForce(Vector3.up * 3f, ForceMode.Impulse);
                     }
                 }
             }
         }

I do get this error code from it... do you know how to fix it?!

PlayerController.cs(92,25): error CS0103: The name 'CharacterColtrol' does not exist in the current context

CharacterControl is script in my project from which i am using property to access rigidbody , in your case it'll be rb.AddForce

Could you post your entire script so I can see what I can change in mine?! Because it is not working yet.
