Ignore collisions with all objects tagged in a string array??

I give up I cant get this to work.
I have an alpha shader called Microsplat that lets me paint holes. I wanted to paint a hole for a subway entry hole. Obviously needed to disable the terrain collider for objects in a specific area and ONLY for certain objects this is what I'v tried:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class EnterHole : MonoBehaviour
6. {
7.     [Tooltip("List of Tags that you want to Ignore Collision for")]
8.     public string[] entityTagList = {"Bullet","Player","Enemy"};
9.  
10.     [Tooltip("Terrain you want to ignore Collisions with")]
11.     public TerrainCollider terrainSlot;
12.  
13.     private Collider c;
14.  
15.     void OnTriggerEnter(Collider other)
16.     {
17.         foreach (string TagToTest in entityTagList)
18.         {
19.             if (other.gameObject.tag == TagToTest)
20.             {
21.                 Debug.Log(other.gameObject.tag+" has entered");
22.                 c = GetComponent<Collider>();
23.                 Physics.IgnoreCollision(c, terrainSlot, true);
24.             }
25.         }
26.     }
27.  
28.     void OnTriggerExit(Collider other)
29.     {
30.         foreach (string TagToTest in entityTagList)
31.         {
32.             if (other.gameObject.tag == TagToTest)
33.             {
34.                 Physics.IgnoreCollision(other, terrainSlot, false);
35.             }
36.         }
37.     }
38.  
39. }

Its not ignoring collisions for any thing that enters. It DOES detect the objects tag that enters the collider. So I know that's working at the very least.

But I cant get it to yank the colliders Id appreciate any help.

 

The collision with the trigger has already occurred in order for this code to be called in OnTriggerEnter()
You cannot go back in time and undo the physics event that happened

 

If I understand correctly, you try to prevent the collision between the hole and the objects. You should try something like:

Code (CSharp):

1.     using System.Collections;
2.     using System.Collections.Generic;
3.     using UnityEngine;
4.    
5.     public class EnterHole : MonoBehaviour
6.     {
7.         [Tooltip("List of Tags that you want to Ignore Collision for")]
8.         public string[] entityTagList = {"Bullet","Player","Enemy"};
9.    
10.         [Tooltip("Terrain you want to ignore Collisions with")]
11.         public TerrainCollider terrainSlot;
12.    
13.         private Collider c;
14.    
15.         void OnTriggerEnter(Collider other)
16.         {
17.             foreach (string TagToTest in entityTagList)
18.             {
19.                 if (other.gameObject.tag == TagToTest)
20.                 {
21.                     return;
22.                 }
23.             //Add here what should happen if the tag is not included in entityTagList
24.             }
25.         }
26.    }
27.  

 

That would be true yes, but I have a trigger volume larger than my actual collider. So that logic isnt quite correct.

@dara_rw
What exactly is the return; doing?
The only thing i want to make happen is it the tags listed in my array are on the object they do not get affected by the terrain collider so long as they are in the trigger volume. I didn't post the on trigger ext part simply because if it doesn't work on enter then there no point having both yet. It will be a temporary state.

//Add here what should happen if the tag is not included in entityTagList
I'm not sure I follow here? DO i really need to make a else then do nothing given that i tried to make it sense ONLY objects with my set tags?

In any case this is what I have that sorta works, I haven't tested it on multiple objects yet, but I suspect that's remaining issue.:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class EnterHole : MonoBehaviour
6. {
7.     [Tooltip("List of Tags that you want to Ignore Collision for")]
8.     public string[] entityTagList = {"Bullet","Player","Enemy"};
9.  
10.     [Tooltip("Terrain you want to ignore Collisions with")]
11.     public Terrain terrain;
12.     private TerrainCollider terrainSlot;
13.     private Collider myCollider;
14.    
15.  
16.     void Start()
17.     {
18.         terrainSlot = terrain.GetComponent<TerrainCollider>();
19.     }
20.  
21.     void OnTriggerEnter(Collider other)
22.     {
23.         foreach (string TagToTest in entityTagList)
24.         {
25.             if (other.gameObject.tag == TagToTest)
26.             {
27.                 Debug.Log(other.gameObject.tag+" has entered");
28.                 myCollider = other.GetComponent<Collider>();
29.                 Physics.IgnoreCollision(myCollider, terrainSlot, true);
30.             }
31.         }
32.     }
33.  
34.     void OnTriggerExit(Collider other)
35.     {
36.         foreach (string TagToTest in entityTagList)
37.         {
38.             if (other.gameObject.tag == TagToTest)
39.             {
40.                 Debug.Log(other.gameObject.tag + " has walked back out");
41.                 myCollider = other.GetComponent<Collider>();
42.                 Physics.IgnoreCollision(myCollider, terrainSlot, false);
43.             }
44.         }
45.     }
46. }
