Force is being added to wrong RigidBody

Question

I'm using a script that adds force to the player when in collision with an enemy, my problem however is that the force gets added to the enemy instead of the player.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Bounce : MonoBehaviour
 {
     void OnCollisionEnter(Collision c)
     {
         // force is how forcefully we will push the player away from the enemy.
         float force = 1000;
 
         // If the object we hit is the enemy
         if (c.gameObject.tag == "Thump")
         {
             print("Hit");
             // Calculate Angle Between the collision point and the player
             Vector3 dir = c.contacts[0].point - transform.position;
             // We then get the opposite (-Vector3) and normalize it
             dir = -dir.normalized;
             // And finally we add force in the direction of dir and multiply it by force. 
             // This will push back the player
             print("Step 2");
             GetComponent<Rigidbody>().AddForce(dir * force);
         }
     }
 }

To get the rigidbody of the object you collided with, use

 c.gameObject.GetComponent<Rigidbody>()

If I replace GetComponent<Rigidbody>().AddForce(dir * force); with c.gameObject.GetComponent<Rigidbody>().AddForce(dir * force); the force still just gets added to the object and not the Player, no matter who I attach the script to (and changing the tags accordingly).

If your player character's velocity is not controlled by the rigidbody, pushing the rigidbody will not be a solution. Get your script component from the player GameObject and apply force to that - which is something you have to make your character controller script support in the first place.
