Why does my player fly through my barrier?

Question

I want to create an invisible barrier that my player will just bump into if it collides into it. I followed this thread to create my barrier https://answers.unity.com/questions/52283/invisible-walls.html. It works pretty well for the most part except for the fact that if I keep bumping into the wall, the player can go right through it. How would I fix this?

First thing to check if do all your invisible barrier have Colliders on them? Are the Collider's "Is Triggers" box clicked on?

Second thing If you have a Rigidbody and all the proper Colliders and you're not ignoring the collisions via code or anything like that.. Try setting your Rigidbody's Collision Detection to "Continuous".

Discrete Detection: Checks the next frame "Is the collider touching another collider in this frame? If not, move there, if so, we collided"

Continuous Detection: Fires a Raycast in the direction of movement to check the collision before they happen.

And Third is please post your code in the reply section so i can help you with the code . Cause maybe it is your problem

I checked the "Is Trigger" box for the Collider and this caused the player to die when it touched the collider. I set the Collision Detection to Continuous but it doesn't seem like it did anything. This is the code I have for the barrier:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class BarrierController : $$anonymous$$onoBehaviour {

 // Use this for initialization
 void Start () {
     GetComponent<Rigidbody> ().velocity = new Vector3 (0, 0, 7);
 }

}

This is the code for the Collision: using System.Collections; using System.Collections.Generic; using UnityEngine;

public class DestroyContact : $$anonymous$$onoBehaviour {

 PlayerController player$$anonymous$$ovement;
 CameraController camera$$anonymous$$ovement;
 public GameObject player;

// public Camera camera; public ParticleSystem particleSystemPlayer; public Vector3 PosofDeadPlayer;

 void Awake()

 {

     player$$anonymous$$ovement = GetComponent <PlayerController> ();

// camera$$anonymous$$ovement = GetComponent(); }

 void OnTriggerEnter (Collider other)
 {
     if (other.gameObject.tag == "Floor") {
         return;
     }
         
     if (other.gameObject.tag != "Floor") {
         Destroy (gameObject);
         PlayerisDead ();

 
     }

 }



 void PlayerisDead()

 {
         player$$anonymous$$ovement.enabled = false;
     //    camera$$anonymous$$ovement.enabled = false;
         PosofDeadPlayer = player.transform.position;
         particleSystemPlayer.transform.position = PosofDeadPlayer;
         particleSystemPlayer.Play (true);
 }

}

Rigidbody > collision detection > continuous
