Foot Steps on Physics materials not working properly in List

Hi Im a bit new to List's and I was trying to store my physicsmaterials in a List for my footstep sounds. When I walk on the physics material it does trigger but only ever triggers the first material in the List and wont trigger the other ones.

Code (CSharp):

1.     public List<PhysicMaterial> footStepPhysicsMaterials = new List<PhysicMaterial>();
2.  
3.     void OnCollisionEnter(Collision hit)
4.     {
5.         //groundType = 0;
6.  
7.         //Debug.Log("Sim is walking in no defined mateial");
8.  
9.         if (hit.collider.sharedMaterial == footStepPhysicsMaterials[0])
10.         {
11.             groundType = 1;
12.             //Debug.Log("Sim is walking in gravel physics material");
13.         }
14.  
15.         if (hit.collider.sharedMaterial == footStepPhysicsMaterials[1])
16.         {
17.             groundType = 2;
18.             //Debug.Log("Sim is walking on physics metal");
19.         }
20.         if (hit.collider.sharedMaterial == footStepPhysicsMaterials[2])
21.         {
22.             groundType = 3;
23.             //Debug.Log("Sim is walking on physics Concrete");
24.         }
25.         if (hit.collider.sharedMaterial == footStepPhysicsMaterials[3])
26.         {
27.             groundType = 4;
28.             //Debug.Log("Sim is walking on physics grass");
29.         }
30.  
31.     }

 

When in doubt, Debug !

Code (csharp):

1. Debug.Log( gameObject.name + " has collided with " hit.collider.gameObject.name );
2. Debug.Log( hit.collider.gameObject.name + " has physics material " hit.collider.sharedMaterial.name );

Also consider using a loop :

Code (csharp):

1. groundType = -1;
2.  
3. for ( int i = 0; i < footStepPhysicsMaterials.Length; i++ )
4.    if ( hit.collider.sharedMaterial == footStepPhysicsMaterials[i] )
5.      groundType = i;
6.  
7. if ( groundType == -1 ) Debug.LogWarning( "no match found for " hit.collider.sharedMaterial.name );
8. else Debug.Log( "Sim is walking on physics " + footStepPhysicsMaterials[groundType].name );
