When a JobDebugger error is not an error, but a warning

Code (CSharp):

1.  
2. foreach (var group in GameGroups.DOOFUSES.Groups)
3. {
4.     var collection = entitiesDB.QueryEntities<PositionEntityStruct>(group);
5.     if (collection.length == 0) continue;
6.     var entityCollection = collection.GetNativeEnumerator<PositionEntityStruct>();
7.     var job = Entities.ForEach((ref Translation translation) =>
8.                                {
9.                                    ref readonly var positionEntityStruct =
10.                                        ref entityCollection.threadSafeNext.position;
11.                                    translation.Value =
12.                                        new float3(positionEntityStruct.x, positionEntityStruct.y,
13.                                                   positionEntityStruct.z);
14.                                }).WithBurst()
15.                       .WithSharedComponentFilter(new UECSSveltoGroupID((uint) @group)).Schedule(inputDeps);
16.     combinedDependencies = JobHandle.CombineDependencies(combinedDependencies,
17.                                                          new DisposeJob<EntityCollection<
18.                                                                  PositionEntityStruct>.EntityNativeIterator<
19.                                                                  PositionEntityStruct>>(entityCollection)
20.                                                             .Schedule(job));
21. }
22.  

I get:

Code (CSharp):

1. InvalidOperationException: The previously scheduled job RenderingDataSynchronizationEngine:<>c__DisplayClass_OnUpdate_LambdaJob0 writes to the NativeArray <>c__DisplayClass_OnUpdate_LambdaJob0.Data._lambdaParameterValueProviders.forParameter_translation._type. You are trying to schedule a new job RenderingDataSynchronizationEngine:<>c__DisplayClass_OnUpdate_LambdaJob0, which writes to the same NativeArray (via <>c__DisplayClass_OnUpdate_LambdaJob0.Data._lambdaParameterValueProviders.forParameter_translation._type). To guarantee safe
2.  

While it's true that I am scheduling the jobs on purpose to run in parallel and not in serial, If I am not wrong or I misunderstood the code, the filter should guarantee that I am writing in separate entity arrays. I guess the JobDebugger cannot know that (could it know?). Thoughts?

 

It knows only down to typing and not exactly which chunks, if you know your filter guarantees it then I guess you should WithNativeDisableContainerSafetyRestriction

 

Thanks I was looking exactly for this answer

 

WithNativeDisableContainerSafetyRestriction needs a captured variable as parameter, it doesn't disable the check for the whole foreach. Thoughts?

 

How about use CDFE of Translation instead so that became an imported container?

 

I guess at that point I may even just not use foreach and make a custom IJobParallel
