Resolved Way to change MaterialMeshInfo inside IJobChunk?

Hey everyone,

Like the title says, I need to change the material id of entity's MaterialMeshInfo.

The problem is, I can't use the ref MaterialMeshInfo inside IJobChunk Execute.

How do I pass a query with the data to IJobChunk and then modify it inside?

(Note: I know I can do this inside IJobEntity but I need to use Chunks).

Thanks!

 

the array you get from chunk.GetNativeArray points to inside the chunk, so you simply have to get a value, modify it and reassign it at the same index

Code (CSharp):

1.  
2.     [BurstCompile]
3.     public struct UpdateTranslationFromVelocityJob : IJobChunk
4.     {
5.         public ComponentTypeHandle<MaterialMeshInfo> MMTypeHandle;
6.  
7.         [BurstCompile]
8.         public void Execute(in ArchetypeChunk chunk, int unfilteredChunkIndex, bool useEnabledMask, in v128 chunkEnabledMask)
9.         {
10.             NativeArray<MaterialMeshInfo> mmInfo = chunk.GetNativeArray(ref MMTypeHandle);
11.  
12.             var enumerator = new ChunkEntityEnumerator(useEnabledMask, chunkEnabledMask, chunk.Count);
13.             while (enumerator.NextEntityIndex(out var i))
14.             {
15.                 var info = mmInfo[i];
16.  
17.                 info.Material++;
18.  
19.                 mmInfo[i] = info;
20.             }
21.         }
22.     }

 

Thank you so much! Just what I was looking for. Works great for me!
